  var idValue= document.getElementById('id').value;

That's a perfectly valid statement, not sure what your IDE is having a problem with here. Various libraries have shortcuts for this (syntax shortcuts, not performance shortcuts), but none of that prevents the core JavaScript functionality from working, it's 100% valid.

I guess it's expecting the YUI style:

var element = new YAHOO.util.Element('id');
var idValue = element.get('value');

...but either method works, use whichever you want. I would prefer the shorter core javascript syntax here.

Babu,

As noted, the original code snippet does not use any JS library -- it sounds like the IDE is badly configured. Nick's answer looks good for YUI 2. In the newer YUI 3 syntax, you might do this:

YUI().use("node", function(Y) {
  var value = Y.one("#id").get("value);
});
