change color of div

Dear experts

I have a image and a text next to the image .. like this
“ IMAGE “   click on the image

Now when user clicks on the image, i am passing an id and  I am calling a function expandcontent. i.e
onClick="expandcontent(id)">
 and expandcontent function is this
function expandcontent(id){
 
       if (ccollect.length>0){
       document.getElementById(id).style.display=(document.getElementById('sc'+id).style.display!="none")? "none" : ""
            document.getElementById(id).src=(document.getElementById('sc'+id).style.display=="none")? expandsymbol : contractsymbol
            
      
      
}
}
In my jsp the div is placed right under the image.
The above function hides and unhides the div when user clicks on the image. Now my requirement is first time when user clicks on the image the div is unhidden  and the background color of the first row in that
div should change from white to blue. I am able to unhide the div but any idea how i can change the color.


Thanks
J

the code for changing the background color would be:

document.getElementById(id).style.backgroundColor = "#00f"; // #0000FF BLUE ; #FFFFFF WHITE

im not quite sure where you intend to change the background color though.
but whether div nor td the code would change the background color of the element.

hope that helps,

Since you want to show and changes color, it can be efficiently handled by css className

e.g.


<style type="text/css">
div.show { display: block; background-color: blue;  }
div.hide { display: none;  background-color: white; }
</style>
<script language="javascript">
function ShowHide (id, className) {
document.getElementById (id).className = className;
return false;
}
</script>
<a href="#" onclick="return ShowHide ('div1', 'show');">Show</a>
<a href="#" onclick="return ShowHide ('div1', 'hide');">Hide</a>
<div id="div1" >&nbsp;</div>
