jquery - how to get selected text from html select which dynamically is created? -

this part of 1 page numberofp integer database , variable.

<div> <%  string matn = "";  (int = 0; < numberofp; i++)  {      matn+= " <div class='cmsdiv'>";       matn += "<input id='text"+i+"' class='labelhid' type='text' />";      matn += "<select id='select"+i+"' class='drophid'>";      matn += "<option>value= '"+ "خیلی زیاد"+"'>خیلی زیاد" + " <option value= '"+"زیاد'"+">زیاد";      matn += "</select>";      matn += "</div>";      response.write(matn);      matn = "";  } %> </div> 

now want know in each "cmsdiv" text of html select, , value , change 3rd item of class (which has 3 element) in code behind.

i wrote code selected item , pour label , got label. not work. why?

<script type="text/javascript"> $(document).ready(function () { $('.cmsdiv .drophid').each(function() {        var selectedtext = $(this).find('option:selected').text();        document.getelementbyid("labelhid").value = selectedtext;    });    }); </script> 

your select tag has id attribute. make while loop , increment inside of it, break when no longer find object:

var = 0; while (true) {     var select = document.getelementbyid('select' + i);      if (!select) {break;}     i++; }
