Jquery Selector not working in IE7

For the following HTML

<div id='parent'> 
  <input id='child' type=hidden value=''/>
</div>

I am doing

开发者_高级运维$('#parent #child').val('test')

OR

$('#parent > #child').val('test')

but none of the above is working in IE7. It does work in Firefox though

Any idea why is it not working ?

---

is it because you've got the HTML wrong? You should use " for attribute values. Sometimes IE is more sensitive to these things than Firefox

Your syntax seems correct. The only stuff I can think of that can muck this up are:

• Make sure you've got your code between a $(document).ready() block
• Maybe try .prop() instead of .attr() if you're using jQuery 1.6+

Try $('#child').val('test'); which would probably give the same result.
