javascript - Add dynamic option selection list in jquery -


i need add selection menu dynamically.that means when user select on option selection menu add new new selection menu , when user select option new selection menu, should again add new option menu.

here have tried using jquery. double selection menu. , work first selection menu.how can change code meet requirement?. 

<html>      <head>         <script type="text/javascript" src="http://code.jquery.com/jquery-1.7.2.js"></script>         <script>             jquery(function ($) {                 $('.target').change(function () {                     $("select option:selected").each(function () {                         $('#other').append('<select class="target"><option value="3" selected="selected">option1</option><option value="4" selected="selected">option2</option>  </select>');                     });                 });             });         </script>     </head>      <body>         <form>             <input class="target" type="text" value="field 1" />             <select class="target">                 <option value="1" selected="selected">option 1</option>                 <option value="2">option 2</option>             </select>         </form>         <div id="other"></div>     </body>  </html>

use on delegated event dynamically added element

$(document).on('change','.target',function() {      $("select option:selected").each(function () {          $('#other').append('<select class="target"><option value="3" selected="selected">option1</option><option value="4" selected="selected">option2</option>  </select>');   }); });

delegating document works..however , recommeneded delegate closest static parent container performancewise.
