to retrieve all DIVs ID and perform some action

[kadnan]

hi

suppose I have 3 DIVs with IDs

<div id="id1">A</div>
<div id="id2">B</div>
<div id="id3">C</div>

now i want to make a javascript function which takes inut a DIV ID and then Hide all DIVs whose ID isnt equal to supplied iD

i tried following but no luck.
[codes]
var objDiv=document.getElementsByTagName("DIV");

for (LC = 0; LC < objDiv.length; LC ++)
{
alert(objDiv[LC].Id);
}

[/codes]
any help pls?

Thanks

function hideDivsButOne(id)
{
  var divs = document.getElementsByTagName('div');
  for(var k=0, div; k<divs.length; k++)
  {
    var div = divs[k];
      div.style.display = (div.id==id)? 'block':'none';
  }
}
