<script>
 function display(){
$(".unitId_0").select2("val","hr");

</script>

please tell me where I did mistake?

Answer 1

You mean the value in both boxes should be same, right?

$(function () {
    $(".itemid_0").keyup(function () { // on key up in first box
        var value = $(this).val();     // get its value
        $(".unitId_0").val(value);     // set the value of the second box to it
    });
});

这是您要找的吗？

 $('.unitId_0').val("hr");

Answer 3

you can do this like,it should work.

var a=$(".itemid_0").val();
$('.unitId_0').val(a);

you can use keyup or onclick events
