javascript - Detect change of option values of an select field using jquery -


is there way of event binding recognize when options of select field changed different, external, not editable javascript?

just clearify: don't want listen value changes, want listen change of dom structure

have tried this?

this tell if there change structure. 

$(".selectbox").bind("domsubtreemodified", function()   {      $(".message").append("structure changed<br>");  });      $("#add").click(function()   {      $(".selectbox").append("<option>added</option>");  });
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>    <button id="add">add select</button>      <select class="selectbox">      </select>      <div class="message"></div>

if looking data or attributes. looking mutationobserver

mutationobserver provides developers way react changes in dom. designed replacement mutation events defined in dom3 events specification.
