Question

I have written a jQuery code to get an attribute from a TR tag in html. The code works in IE 8, but when I run that in IE 9 I get a error “Function expected”. The code is below:

$(".grid tr").each(function () {

  //I've inserted an attribute called idRow in each grid row. 
  if(this.attributes("idRow") != null) //I get the "Function expected error" here
  {
      ...
  }

});

What’s the code problem? Why it works in IE 8?

Answer 1

To take that approach, you’d need…

this.attributes.getNamedItem('idRow').nodeValue

or…

this.attributes.item('idRow').nodeValue

…although, I’d suggest simply using getAttribute().

this.getAttribute('idRow')
