bootstrap-select add item and select it

Question

I'm using Silvio Moreto's Bootstrap Select.

On my page I have a button that opens a modal with an input box that allows you to add an item to the selectpicker. I would then like to automatically have that item selected but I can't get it to work.

The code I have is :

$('#myselect').append('<option val="'+newitemnum+'">'+newitemdesc+'</option>');
$('#myselect').val(newitemnum);
$('#myselect').selectpicker('refresh');

But it just doesn't work. The item doesn't get selected.

I have tried replacing the selection line with :

$('#myselect').selectpicker('val',newitemnum);

but that doesn't work either

Any ideas much appreciated (although the item DOES get added to the selectpicker).

Answer 1

You have a typo. Instead of:

$('#myselect').append('<option val="'+newitemnum+'">'+newitemdesc+'</option>');

You need:

$('#myselect').append('<option value="'+newitemnum+'">'+newitemdesc+'</option>');

Here is a JSFiddle demo: http://jsfiddle.net/xbr5agqt/

The "Add and select 'Soy Sauce' option" button does the following:

$("#myselect").append('<option value="'+newitemnum+'">'+newitemdesc+'</option>');
$("#myselect").val(4);
$("#myselect").selectpicker("refresh");

One slightly faster approach (used by the "Add and select 'Relish' option" button) is to append the new <option> element with the selected attribute already applied:

$("#myselect").append('<option value="'+newitemnum+'" selected="">'+newitemdesc+'</option>');
$("#myselect").selectpicker("refresh");
