Resetting Select2 value in dropdown with reset button

I'd try something like this:

$(function(){
    $("#searchclear").click(function(){
        $("#d").select2('val', 'All');
    });
});

version 4.0

$('#d').val('').trigger('change');

This is the correct solution from now on according to deprecated message thrown in debug mode: "The select2("val") method has been deprecated and will be removed in later Select2 versions. Use $element.val() instead"

You can also reset select2 value using

$(function() {
  $('#d').select2('data', null)
})

alternately you can pass 'allowClear': true when calling select2 and it will have an X button to reset its value.
