javascript - 如何将表行索引传递给 JavaScript 函数

标签 javascript html onchange drop-down-menu tablerow

我有一些正在创建 html 表的 php 代码。在其中我有一个表单，其中有不同的下拉菜单，其中包含 onChange 事件。我需要将表行索引传递给 javascript 函数。有什么办法可以做到这一点吗？如果可以的话请举个例子。谢谢!

下面列出了我的 php 代码:

最佳答案

我习惯了 Zend，所以这就是我通常的做法，而不是回显 html，只需键入 html，然后使用 <?for:?>句法。就像下面这样。 

 <table id='inputTable'>
    <form id='trade' name='trade' method='post' action=''>
    <tr id = 'labelRow0' name = 'labelRow0' style='display:table-row'>
      <td>Spread Type</td>
      <td>Option/Future</td>
      <td>Year</td>
      <td>Month</td>
      <td>Strike</td>
      <td>Call/Put</td>
      <td>Buy/Sell</td>
      <td>Price</td>
      <td>Quantity</td>
      <td>Delta</td>
      <td>House</td>
    </tr>
    <tr id = 'inputRow0' name = 'inputRow0' style='display:table-row'>
