Coordinates of a object in javascript...

[Devesh H Rao]

Hi ppl,
is it possible to find out if a object like select or a text box is present at a given coordinate.
say for eg i have the mouse on (x,y) coordinate as(300,300) is it possible for me to know what object lies at that coordinates.
thanx for any help in advance

Hi Devesh,
you could use an image-map

<map name="example">
<area shape="rect" coords="11,10,59,29" href="http://javaranch.com" alt="Rectangular Object x,y,x,y">
<area shape="circle" coords="150,150,50" href="javascript:alert('circle')" alt="Circle Object x,y,r">
<area shape="poly" coords="48,311,105,248,96,210" href="#" onClick="save2hiddenField( 'polly' )" alt="Polygon x1,y1,x2,y2,x3,y3,..." >
</map>
<img src="objetcs.gif" width="350" height="350" border="0" alt="Karte" usemap="#example">

this also works with a transparent pixelsize Pic positioned absolutely over your objects

Thanx christian for the answer but that is not what i was looking for i think i will give a example to the exact problem that i am facing.
In our application i have a menu which unfolds and goes to n levels which is dynamically decided from the no of nodes a user has access to in the database.
The problem in the page(it is a frame consisting of 3 framesets the top frame contains the menu, the middle frame the body and the third frame is the footer which contains the processing info) is when ever the menu unfolds over a select box the select box peeks thru the menu due to which the menu is not visible properly.
i have deployed a crude method in which i hide all the select objects in the page on opening the menu and the again make them visible when the menu collapses.I wanted to hide only the sepecific select box as an when it hinders the display of the menu hence my requirement for finding a object at a particular coordinate on the page.
Thanx for the help.

There is a way to do it, I just got home from a trip, so I need to get some stuff done. If is done by referencceing the element object...

Look at this, I only used the coordinates on the blue div box.
