Question

I have code like this

if ($('#chkCheckAll').is(':indeterminate') == true) 
{
}

But it is throwing exception in ie 8

what can do instead of this in Jquery to work with ie8

Answer 1

Use this instead:

var $allChk = $('#chkCheckAll');
if ($allChk[0] && $allChk[0].indeterminate ) {
  ... 
}

The problem is that ‘:indeterminate’ pseudo-expression is not supported by IE8 querySelectorAll implementation. But in your case, it’s actually not required to use it, as you can query the corresponding property of DOM element itself
