Question

Been trying to work this out for a little while now, no luck.

jQuery("#choosenCause option:selected").removeAttr("selected","selected");

jQuery('#choosenCause option[value="'+json.causeID+'"]').attr("selected",true);

I’m using the above, it adds selected="selected" to the right element, but does not change the selected element that the user sees.

Answer 1

To set the selected option of a select element, use val():

jQuery('#choosenCause').val(json.causeID);
