Question

The element is:

<input type="text" name="idName" id="idName" value="" size="2" maxlength="2" />

I use this selector:
alert($('#idName').val());

In IE 8:
cannot alert the content

In IE 9 and firefox 8:
can alert the content

why? How to fix?

Answer 1

Make sure the code that calls the alert($('#idName').val()); is inside a $(document).ready(function(){..}); part, so that it runs after the DOM is ready..

$(function(){
    alert($('#idName').val());
});
