我有一个网格，这里是 html 代码：

<table cellspacing="0" border="1" style="border-collapse:collapse;" id="grid1"
   rules="all">
        <tbody><tr>
 <th scope="col">Nr de ord</th>
 <th scope="col">StudentId</th>
 <th scope="col">Name LName</th>

 <th scope="col">
      <span id="mondayText">monday<br></span>
      <span id="monday">14.05.2012</span>
  </th>
<th scope="col">
     <span id="thuesdayText">thuesday<br></span>
     <span id="thuesday">15.05.2012</span>

<th scope="col">
     <span id="wednesdayText">wednesday<br></span>

                          </td>
        </tr>
    </tbody></table>

使用 jQuery，我正在计算有多少选择具有索引 1 和多少索引 2，并在更改事件的此函数中计算：

$(document).ready(function () {
             var collection = $('select.ddlJ');
             console.log(collection);
             for (var element in collection)
             $(element).change(function () {

    $('select.ddlJ').change(function (e) {
$(this).parent().parent().find('td:last').prev().find('span').html(
$(this).parent().parent().find('select.ddlJ').filter(function () {
return $.trim($(this).val()) == 'm'; }).length);

$(this).parent().parent().find('td:last span').html(
$(this).parent().parent().find('select.ddlJ').filter(function () {
return $.trim($(this).val()) == 'n'; }).length );

     });
   });
 });

但是现在我想在加载网格时进行相同的计算。

看到这个链接。但它想在加载页面时动态添加。这是你的问题？？

获取change事件的内容并将其设为单独的函数。在脚本底部调用该函数。
