I need a cross-platform way to insert OPTIONs into a SELECT with jQuery. I think I recall in the past that IE6 does nothing when this is called:
First off, you aren't waiting for the DOM to be ready with your code. You should be wrapping your jQuery code in:
$(document).ready(function() {
$('#myselect').append('');
$('#myselect').append('');
});
I'm not sure about IE6 compatibility, but you could try the .appendTo function instead, such as:
$('').appendTo("#myselect");
example:
