<p>Yeah, it is possible using the <code>document.elementFromPoint</code> method.<br>
This is how it is documented by <a href="http://msdn.microsoft.com/en-us/library/ms536417%28VS.85%29.aspx" rel="nofollow noreferrer">Microsoft</a>.
Here is <a href="https://developer.mozilla.org/en-US/docs/DOM/document.elementFromPoint" rel="nofollow noreferrer">Mozilla documentation</a>.<br>
The function is almost fully compatible, as you can see in <a href="http://www.quirksmode.org/dom/w3c_cssom.html#documentview" rel="nofollow noreferrer">this browser comparison</a>.</p>

<p>Here is some sample code from MDN docs:</p>

<p><div class="snippet" data-lang="js" data-hide="false" data-console="false" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>function changeColor(newColor) {
  elem = document.elementFromPoint(2, 2);
  elem.style.color = newColor;
}</code></pre>
<pre class="snippet-code-html lang-html prettyprint-override"><code>&lt;p id="para1"&gt;Some text here&lt;/p&gt;
&lt;button onclick="changeColor('blue');"&gt;blue&lt;/button&gt;
&lt;button onclick="changeColor('red');"&gt;red&lt;/button&gt;</code></pre>
</div>
</div>
</p>

<p>have a look at this existing StackOverflow conversation you may find this helps:</p>

<p><a href="https://stackoverflow.com/questions/8813051/determine-which-element-the-mouse-pointer-is-on-top-of-in-javascript">Determine which element the mouse pointer is on top of in Javascript</a></p>

<p>This is using a javascript function <code>document.elementFromPoint</code> and has a great demo that shows a working example. </p>

<p>The jsFiddle URL is: <a href="http://jsfiddle.net/MPTTp/" rel="nofollow noreferrer">http://jsfiddle.net/MPTTp/</a></p>

<p>Code from the fiddle:</p>

<pre><code>$(window).click(function(e) {
    var x = e.clientX, y = e.clientY,
        elementMouseIsOver = document.elementFromPoint(x, y);

    alert(elementMouseIsOver);
});
</code></pre>


<p>It is fairly easy to find the location of a div, when you know the div name. But is there an easy way to get the div id when all I know is the X/Y cords of the screen? </p>

<p>There will be no overlapping divs within a range of divs named '#Items1' to '#Items50' on a board (another div) called #HarbourRadar. Each div #Items can have more than one stacked image in it. </p>

<p>Anyway any hint to find the div out from a location would be greatly appreciated.  </p>

<p>The following code (taken from the answer below on this side) gets the id of the div #HarbourRadar, that is partially right since the div #marker is layered ontop on that one, but does not return the div #marker that is selected - ie one with a higher Z-index. </p>

<pre><code>var pos = $("#marker").position();
alert(document.elementFromPoint(pos.left, pos.top).id);
</code></pre>


Is there a way to find the div name out from from location(x,y cords)

当您知道div名称时，查找div的位置是相当容易的。但是，当我只知道屏幕的X/Y线时，有没有一种简单的方法来获取div id？在名为“#items1”到“#items50”的div范围内(另一个div)，将不会有重叠的div。每个div #Items可以有多个堆叠的图像。无论如何，从某个位置查找div的任何提示都将不胜...
