Select last item in <select> list using jquery [duplicate]

Question

I have a <select> element on my form with the multiple attribute set to "true". After the element gets populated, how can I select the last item in the list using jquery? I want the item to be selected the same way you select it with a mouseclick:

Answer 1

You can try

    var myVal = $('.someclass option:last').val();
    $('.someclass').val(myVal);

where someclass is the select class or it's wrapper element class.

You can do this by index value as well:

var num = $('select option').length;
$('select').prop('selectedIndex', num-1); // For choosing last item in list
