Question: I need to get the value of a hidden input field using JS,

```
   var credoff = parseInt($(this).children('input.credoff:hidden').val());

```

which works fine in FF but does not work in IE, the input im talking of is the following...

```
<input type='hidden' value='$row->coff' class='credoff' name='credoff'/> 

```

Answer: 
Could you try `input[type='hidden']`?
This must work:

var credoff = parseInt($(this).children('input[name="credoff"][type="hidden"]').val());
