I feel like I'm missing something very basic, but I can't get a dropdown menu to work as I expect using Knockout.js. I have a set of objects I want to present in a menu, and I need to find the selected option and post that to the server. I can get the menu to render, but can't seem to get the value of the selected item. My view model looks like this: function ProjectFilterItem( name, id ) { this.Name = name; this.Id = id; } function FilterViewModel() { this.projectFilters = ko.observableArray([ new ProjectFilterItem( "foo", "1" ), new ProjectFilterItem( "bar", "2" ), new ProjectFilterItem(

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: <select id="myselect" size="1"> <option value=""></option> </select> <script type="text/javascript"> $('#myselect').append('<option value="test1">test1</option>'); $('#myselect').append('<option value="test2">test2</option>'); </script> I think I recall that the above worked in all browsers as well as Firefox 2+ and IE7+, but not IE6. Correct? If so, what's the workaround? JavaScript is Cross-Platform, Even IE6. To test how it looks in IE6 open

I've got a select list like this: <select id="selectlist" name="selectproduct" > <option value=""> --- Select product --- </option> <option value="1">Product 1</option> <option value="2">Product 2</option> <option value="3">Product 3</option> <option value="4">Product 4</option> </select> Unfortunately I can't edit it. Is there any method which let me hide the "Product 4" option by default? I'm trying with CSS, but it doesn't work with IE. walterquez To hide it, wrap it with a span tag. $( "#selectlist option[value=4]" ).wrap( "<span>" ); To show it, unwrap the span tag if it has one. if ( $(
