Document.getelementbyid() Returns Null On Ie9

I'm working on a popup and i'm having some hard time with Internet Explorer 9. This is the piece of code that gives me trouble: var popUp= document.getElementById('projectInfo'); p

Solution 1:

Without using function it can't work

window.onload = function() {
   var popUp= document.getElementById('projectInfo');
   popUp.style.left=(tempX-310)+'px';
   popUp.style.top=(tempY-110)+'px';
 }

Solution 2:

IE is having some known issues with getElementById.This post may help .

Solution 3:

In previous versions of IE (and apparently Chrome and Firefox), getElementById would check for an object with the given id and if it didn't find it, it would take an element with that name.

IE9 doesn't do this, so you need to make sure you have an element with id = projectInfo, not just name=projectInfo. We just discovered this throughout one of our applications. Not great.
