JavaScript Find Position

I’ve been trying to use the findPosX() & findPosY() functions from Peter-Paul Koch’s excellent ‘quirksmode‘ site. The purpose of these functions is to find the absolute X and Y co-ordinates of an HTML element. They work well in both Internet Explorer and Firefox, but the results can be pretty rubbish on Safari.

I’ve made a small adjustment that fixes this problem. I’ve moved the loop exit from the start of the loop to the middle. Safari was failing to add in the offset of the outermost containing element. Here’s the modified code:

  function findPosX(obj)
    var curleft = 0;
          curleft += obj.offsetLeft;
          obj = obj.offsetParent;
    else if(obj.x)
        curleft += obj.x;
    return curleft;

  function findPosY(obj)
    var curtop = 0;
          curtop += obj.offsetTop;
          obj = obj.offsetParent;
    else if(obj.y)
        curtop += obj.y;
    return curtop;


You are free to use this script for any purpose.

Peter-Paul Koch has implicitly dedicated his original version of this script to the public domain [link]. I hereby dedicate my version of the script to the public domain.

If you wish to give us credit, I suggest you just say: by Peter-Paul Koch & Alex Tingle. A link would be nice, too.

    Hi, I had been trying to use your code on my web site but I still face some problem. I have a couple of questions hope you can help… Thank you.

    I wish to find a X,y or Left,Top position of an image within a web page, can I do that using your script? I had tried using DIV encapsulation on the but I still cannot read out the XY coordinate. Do you have any alternative solution?

    Thank you very much. Regars

    Jared: What? These functions find the X,Y position of an object. Why would you need an alternative solution?

    If it doesn’t work for you, then you’ll need to be more specific. How about an example and an indication of which browser you’re using.

    Hi Jared, I’ve tried these scripts from your site and quirksmode but always get a 0 returned whereever i position the element.

    I’m just using IE6 on XP sp2

    i just have an img tag that i’ve put in various positions, then call you functions always get 0, any ideas?

    Thanks for the fix, solves the same problem in Opera by the way. Here’s a version formatted a little more strictly as far as including the “{” for the if/else statements in case anyone else had a problem with the formatting of the version on this page.

    function findPosX(obj) {
        var curleft = 0;
        if (obj.offsetParent) {
            while (1) {
                if (!obj.offsetParent) {
        } else if (obj.x) {
        return curleft;
    function findPosY(obj) {
        var curtop = 0;
        if (obj.offsetParent) {
            while (1) {
                if (!obj.offsetParent) {

    Hi Thomas,

    I’m an old hand, so I’m able to view your fervent rejection of my
    coding style with a wry humour. In years gone by, I would have been
    offended by your waste of characters and illogical brace-placement. :-P

    When I get a minute, I’ll clean up your version and post it for any
    other K+R luddites who may happen across my page.

    Happy hacking, and I hope that you see the light one day.

  16. Emery Wooten said,

    Jarad and others. I too was getting nothing but 0 returned from the function call. I was calling the function from a script inside a table cell and not from an event like onMouseover.

    If that is your problem, place your calling script OUTSIDE of the table and it will work properly. The function itself should be in the head of your page.

    Programmers scare me with how fanatical they get over their code style. Here is the same code written in compressed format with reverse indent.

    The newbie coder will most likely have their eyes bug out of their sockets just looking at it. If you are an old hand, reverse indenting can be a life saver when its added to scripts of 1,000+ lines. It allows you to see more of the code in one viewing without it scrolling off the page. Although it does scroll to right some, most of the scrolling is controlled.

    function findPosX(obj){
    var curleft = 0;
    if (obj.offsetParent){
    if (!obj.offsetParent){break}
                         }else if(obj.x){curleft+=obj.x}
    return curleft;
    function findPosY(obj){
    var curtop = 0;
    if (obj.offsetParent){
    if (!obj.offsetParent){break}
                        }else if(obj.y){curtop+=obj.y}
    return curtop;

    Emery Wooten is right – the script only works in IE when called from an event (onload doesn’t seem to count). I had the same problem as everyone else, with a zero or -1 return, but this has fixed it. Thanks Alex and Emery!

    Ran across this by accident searching for something else, but here’s the function I typically use, not sure how compatible it is but I find it a bit cleaner.

    function getPos(inputElement) {
        var coords =  new Object();
        coords.x = 0;
        coords.y = 0;
        try {
            targetElement = inputElement;
            if(targetElement.x && targetElement.y) {
                coords.x = targetElement.x;
                coords.y = targetElement.y;
            } else {
                if(targetElement.offsetParent) {
                    coords.x += targetElement.offsetLeft;
                    coords.y += targetElement.offsetTop;
                    while(targetElement = targetElement.offsetParent) {
                        coords.x += targetElement.offsetLeft;
                        coords.y += targetElement.offsetTop;
                } else {
                    //alert("Could not find any reference for coordinate positioning.");
            return coords;
        } catch(error) {
            return coords;

    Hi Alex,

    I’ve been using your script pretty much unchanged but it isn’t working in my application. I have a series of photos in a container, each wrapped by a div. The div’s are floated left so that the photos look like they are next to each other in a row and the photos wrap to the next line if there are more photos than can fit on a row. When I try to get the position of any image, I always get the coordinates for the top-left most image in the matrix, not the coordinates of the current image. Basically, the script is giving the position of the image where it would have put it if there wasn’t anything in the way already. Does the offsetLeft & offsetTop fail for floating containers? I’ve tried this on Firefox 1.0.7 & IE 6. Any help would be appreciated, otherwise and FYI to others.

    Tip from quirksmode site if you are trying to position an element using this script:

    “In ’strict mode’ you must add ‘px’ to the value, or Mozilla, Explorer on Mac and Safari will refuse to place the layer anywhere.”


    document.getElementById( element2 ).style.left = findPosX( element1 ) + 'px';

    Great script by the way, thanks for the time saver.

  37. Nitin said,

    15 September, 2006 @ 09:16

    this is not mine just copied from a open source: what = object offsettype = “left” for x-pos and “top” for y-pos

    function getposOffset(what, offsettype) { var totaloffset=(offsettype==”left”)? what.offsetLeft : what.offsetTop; var parentEl=what.offsetParent; while (parentEl!=null) { totaloffset=(offsettype==”left”)? totaloffset+parentEl.offsetLeft : totaloffset+parentEl.offsetTop; parentEl=parentEl.offsetParent; } return totaloffset; }

  38. ericShinn said,

    21 September, 2006 @ 05:31

    How’s this for minimalistic?

    function getPos (obj) { var pos = {x: obj.offsetLeft||0, y: obj.offsetTop||0}; while(obj = obj.offsetParent) { pos.x += obj.offsetLeft||0; pos.y += obj.offsetTop||0; } return pos;


    … and you access the info by: alert(”X = “+getPos(myElement).x+” and Y = “+getPos(myElement).y);

    Cheers, eShinn

    Hi !

    I had a problem in identifying the position of an element inside a div which is scrolling. Is there a way to get the position of the element relative to the displayed area, rather than getting the fixed position always ?

    2 Geeta: For problem in identifying the position of an element inside a div which is scrolling Use prototype.js!!!

    download it from

    read documentation at – in the end of doc about “Position”

    use this function :

    GetBounds : function(element) { var iebody = (document.compatMode && document.compatMode != “BackCompat”)? document.documentElement : document.body;
    var dsocleft = document.all? this.iebody.scrollLeft : pageXOffset; var dsoctop = document.all? this.iebody.scrollTop : pageYOffset;

        var posReal = Position.realOffset(element);
        var pos = Position.cumulativeOffset(element);
        var top =  pos[1] - posReal[1] + dsoctop;
        var left = pos[0] + posReal[1] - dsocleft;
        var offsetWidth = element.offsetWidth;
        var offsetHeight = element.offsetHeight;
        return {left: left, top: top, width: offsetWidth, height:  offsetHeight};

    adapt this function to your needs. i’m note sure it has no errors.

  42. Kalle said,

    22 October, 2006 @ 11:57

    If you need to find the position in Internet Explorer you have to use a timer function, otherwhise Explorer returns “-1″. I think this is because Explorer needs to draw the entire webpage before it can return the position of an element. (In Firefox this is not necessary.) Maybe you can also use “window on load” in IE.

    function findPos(obj) { var curleft = curtop = 0; if (obj.offsetParent) { curleft = obj.offsetLeft; curtop = obj.offsetTop; while (obj = obj.offsetParent) { curleft += obj.offsetLeft; curtop += obj.offsetTop; } }

    return [curleft,curtop];


    function UpdateTimer() { if(timerID) clearTimeout(timerID);

    var position = findPos(document.getElementById("name"));


    setTimeout(”UpdateTimer()”, 1000);

    I’ve been playing around with your script and quirksmode’s script, but like others, I’ve been getting a return of x = 0, y = 0. I tried adding the “px” afterwards to no avail. does it have something to do with the doctype? I’ve tried strict and transitional doctypes for xhtml 1.0 but still nothing. any clue as to what is happening? What’s really strange is that in IE6 and FF, when i put: if (!obj.offsetParent) alert (”no offsetParent”) and it returns that alert.

    Any clues? thanks

    I’ve got return 0 as well. My html page is generated by PHP,javascript and html itself. But in my test page I found that if your html open tag without closed tag. You will get 0 from findpos() function. Does anybody has another method in IE to find element pos?(like obj.x and obj.y in firefox).

    I have also developed a solution for this problem, a little bit shorter but it works also fine:

        function getX(obj){
            return obj.offsetLeft + (obj.offsetParent ? getX(obj.offsetParent) : obj.x ? obj.x : 0);
        function getY(obj){
            return (obj.offsetParent ? obj.offsetTop + getY(obj.offsetParent) : obj.y ? obj.y : 0);

    I’m having a problem with FF2.0.

    I’ve tried this script and others similar to it and related to it. I keep getting strange values for the Y offset. In stylesheets, I set everything to zero: body { padding:0px; margin:0px }. then placed one single image on a blank page with an href around it. using mouseover to show me the y offset, I keep getting different y offsets depending on the height of the image (manually changed for experimentation). The natural height of the image is 88, yet somehow the offset keeps saying 73.

    If I have set everything to zero: 1. shouldn’t the offset always be zero? 2. why does the y offset change every time I change the image height?

  61. Norm Sherman said,

    19 March, 2007 @ 17:29

    Depending on how you implemented this script: I recommend adding ‘obj=document.getElementById(obj);’ right above ‘var curleft = 0;’ and ‘var curtop = 0;’.

    Sans-Quote :)

    Firefox will always return ZERO if it’s not called via an event.

    It seems that this function, and basically every other one I’ve seen on the net has the same problem, which I’ll try to explain here.

    When giving it an A (link element), when that is a container for an image, Mozilla gives very strange result, but it seems that it can be explained.

    In the case of giving an A object displayed as an inline element, with an image contained within, you get basically:

    (Real Y Offset) + (Image Height – Font Height).

    I assume that means Mozilla thinks the A’s position is really where the text would start if it were there.

    You can visualize this problem by putting a border around the A element.

    Setting the display CSS property to block corrects this.

    If you can’t switch to block mode, you can correct for this problem by simply giving the element for the image, and not the A.

    Hey, First of all, thanks a lot for posting the script. It does work with IE, Firefox & Safari. BUT there is one problem: When you rezise the window, the script looses its track of the absolute position of the element and the positioning is then done in a relative manner. e.g the position of the element is 400px from the top. If you scroll down by 100px, and then again refresh the page, the element will be positioned at 500px from the top instead of its absolute position which is 400px.

    Is there a way to get around with this resizing problem.

    Thanks Kunal

    Hi i new to javascript, im using this function to find the Y-postion function findPosY (obj) {

    var curTop=0; if (obj.offsetParent){ while(obj.offsetParent) { curTop+=obj.offsetTop; obj=obj.offsetParent; } } else if (obj.y){ curTop+=obj.y; } alert(curTop); return curTop; }

    This is my html code


    It alert’s only 0.

    Could you help me what im wrong. Thanks in advance.

    I’ve been using the following. It takes into account the scroll position of the window as well as any scrolling objects (css overflow: scroll|auto)

    function getPosition(elementId) {

    var element = document.getElementById(elementId);
    var left = 0;
    var top = 0;
    if (element != null)
        // Try because sometimes errors on offsetParent after DOM changes.
            while (element.offsetParent)
                // While we haven't got the top element in the DOM hierarchy
                // Add the offsetLeft
                left += element.offsetLeft;
                // If my parent scrolls, then subtract the left scroll position
                if (element.offsetParent.scrollLeft) {left -= element.offsetParent.scrollLeft; }
                // Add the offsetTop
                top += element.offsetTop;
                // If my parent scrolls, then subtract the top scroll position
                if (element.offsetParent.scrollTop) { top -= element.offsetParent.scrollTop; }
                // Grab
                element = element.offsetParent;
        catch (e)
            // Do nothing
        // Add the top element left offset and the windows left scroll and subtract the body's client left position.
        left += element.offsetLeft + document.body.scrollLeft - document.body.clientLeft;
        // Add the top element topoffset and the windows topscroll and subtract the body's client top position.
        top += element.offsetTop + document.body.scrollTop - document.body.clientTop;
    return {x:left, y:top};


    You would then use something like the following to use it:

    var pos = getPosition(’IMAGEOS’); alert(’x:’ + pos.x.toString() + ‘, y:’ + pos.y.toString());

    Note that your IMAGEOS object will not exist until the page is loaded. If you need it’s co-ordinates at load time, then wrap it in a function called by window.onload or it can be called from an event from another page object.

    Hello and thanks for the script. I was also having issues with the functions returning only 0.

    I was running the function from onClick-event like this: findPosX(’element_id’)

    Got it working by running it like this: findPosX(document.getElementById(’element_id’))

    If you need to get the position of an element that may be inside a div with scroll content, then you should decrement the scrollTop or scrollLeft values of the element. This is: function findPosX(obj) { var curleft = 0; if(obj.offsetParent) while(1) { curleft += obj.offsetLeft; curleft -+ obj.scrollLeft; if(!obj.offsetParent) break; obj = obj.offsetParent; } else if(obj.x) curleft += obj.x; return curleft; }

    I’m using your script a lot and it goes but…

    Yesterday i’ve tried to find position of DIV element that was created after page load (Ajax environment), the problem is that this DIV have its origin (x=0 , y=0 , position=absolute) not to the window left-top corner, but at left-top corner of its parent that i call AjaxContainer.

    So, find position function retrieve DIV position into AjaxContainer how maximum parent.

    My scenario is BODY -> ELEMENTS -> AJAXCONTAINER (about in middle of page) -> DIV.

    Anyone can help me?

    Tip from quirksmode site if you are trying to position an element using this script:

    “In ’strict mode’ you must add ‘px’ to the value, or Mozilla, Explorer on Mac and Safari will refuse to place the layer anywhere.”


    document.getElementById( element2 ).style.left = findPosX( element1 ) + ‘px’;Great script by the way, thanks for the time saver.

    I dont know if this is a problem due to the script or something else on my project. But when i use this script it works 100% perfect on FF and abit wrong on IE:

    Im using a div centered both horizontally and vertically with the help of a table. On my onmouseover-event i trigger a function that’ll take the x- and y-pos of its div with the help of this script. After that I take these x and y coordinates and put them in yet another div (my little div-popup which is supposed to position itself directly above the div that triggered the onmouseover-event). The thing is, when i change the size of the browser-window my popup-div position itself on different Y-coordinates. The X-coordinates are the same but vertically the popupdiv changes location whenever i resize the browserwindow.

    Any fix for this? :)

    The scripts above will not work for all elements. Elements which are absolute positioned and elements which are relatively positioned on the page will return different values. Relative positioned objects will return the x and y relative to the parent, and thus why the loop through the parent nodes, however, absolute positioned elements will return a value relative to the HTML object of the page but still have the same parent in which they are appended to.

    Also, elements which do not have CSS/javascript assigned position attributes will only be caught with offsetTop and offsetLeft. A mixture of no pre-defined x and y, predefined x, y and absolute x and y will really screw up most scripts. The reason for the -1 values is because the scripts do not exit when they hit the HTML and/or Body objects which are at -1 and 0 respectively.

    The solution to the problems above is to limit the parent nodes in which it calculates the offset top from. Absolute positioned objects should NOT run through a parent check as since they are absolutely positioned, their position is already ABSOLUTE and thus the script should end there and return their position. relative positioned objects and objects which have no top and left assigned to them via css should then be checked against their parent nodes but only certain parent node types.

    Div > Table > TR > TD > TH

    So, say you have an image inside a TH tag, the relative position of the TH tag is important as cellspacing and cellpadding play a huge roll in the positioning of that image within the TH tag. Next the offset parent to the TH tag will be the TR tag which also has to be taken into consideration for the same reasons as stated for the TH tag. Then you’ll hit table which also has to be accounted for and then you’ll either hit some other layout object like a parent table or div, or td, etc.

    In short, x and y position accumulation should only happen for layout objects, divs, tables, spans, and anything else that can be a container for other html elements. positions of the html and body elements should NOT be checked as they are -1 and 0 respectively.

    One more variant of the routine. I found it more convenient to have just one function instead of two which returns a single object pos. The x and y attrs may be accessed using pos.x and pos.y

    Modifications: - merging two functions findPosX and findPosY into one function FindPos - returning a single value ‘pos’ - getting rid of the ‘break’ statement from within the ‘while’ loop

    Whould it still work under the browsers other than IE?

    function FindPos(ctrl) { var pos = {x:0, y:0};

    if (ctrl.offsetParent)
            pos.x += ctrl.offsetLeft;
            pos.y += ctrl.offsetTop;
            ctrl = ctrl.offsetParent;
    else if (ctrl.x && ctrl.y)
        pos.x += ctrl.x;
        pos.y += ctrl.y;
    return pos;

    This works most of the time in as many browsers as I have found, but if you nest the element inside a table, inside a div, inside a table, inside a table, inside a table, inside a div, it doesn’t work in FireFox and Chrome, and returns 0 for x and y. The way I know is because I use it in a SharePoint web part that has a customized master page that was done with a table layout. Yuk, and I still haven’t found a way to get it to work now. For some crazy reason, it actually does work in IE still. That’s not the way things usually go!

    Great script, thanks very much. Spent weeks trying to get positions from images etc – nearly bald now because of it! So I am very happy that I came across your solution. Cheers!

    thanks @Guy Schalnat & @Peter-Paul Koch & Alex Tingle. Nothing else worked for my relative positioned divs.

    @Guy Schalnat script works like a charm!

    Greetz, Flo

    Very nice, script. However I found that it didn’t work if there object was nested in other objects, multiple ones of which were absolutely positioned. After no small amount of heartache, I added a counter to the loop, starting with 0 and incremented in the loop. I then added the following if clause in the beginning of the “do” loop (note this is IE-centric, but could easily be generalized):

    if (obj.currentStyle.position == ‘absolute’ && counter > 0) break;

    I initially tried to add the additional restriction in the “while” constraint so I wouldn’t have to use a counter, but I kept getting javascript errors when I did that. Anyway, it seems to help in this situation.

    Cheers Works fine. Must have visited goodness knows how many web sites with rubbish solutions, before finding this.

    Update, almost works fine, but…

    It doesn’t take into account the possibility that the browser window is reduced in size so that scroll bars appear. Then when the window is scrolled, the coordinates are offset and incorrect, which messes up mouse detection etc. It’s a problem in all browsers from what I can see.

    But I see someone in the comments has pointed out the issue of scrollbars etc.
