jQuery $ .live()不适用于iPhone上的表行

问题描述:

我正在使用jQuery的 $。live()功能点击表行。

在Chrome,Firefox甚至桌面上都能完美运行Windows Safari - 但不在iPhone上。

$。bind()无处不在,但出于显而易见的原因,我想使用其他功能。

I'm making table rows click-able with jQuery's $.live() function.
Works perfectly on Chrome, Firefox and even desktop Windows Safari -- but not on the iPhone.
$.bind() works everywhere, but for obvious reasons I'd like to use the other function.

有没有人知道它为什么不起作用以及我该如何解决?

下面的示例代码。

Does anyone have any idea why it doesn't work and how can I fix it?
Example code below.

<!DOCTYPE html>
<html lang="en">
<head>
 <title>test</title>
 <meta charset="utf-8" />
 <meta name="viewport" content="user-scalable=no,width=device-width" />
 <meta name="apple-mobile-web-app-capable" content="yes" />
 <style type="text/css">table { width: 100%; border-collapse: collapse; } table tr {     background: #eee; } table td { padding: 10px; border-top: 1px solid #ccc; }</style>
 <script type="text/javascript" src="http://jquery.com/src/jquery-latest.pack.js">        </script>
 <script type="text/javascript">
$(document).ready(function() {
  /* $.bind() works */
  /*
  $('table').find('tr').bind('click', function() {
    alert($(this).text());
  });
  */
  /* $.live() doesn't */
  $('table').find('tr').live('click', function() {
    alert($(this).text());
  });
});
 </script>
</head>
<body>
 <table>
  <tbody>
   <tr><td>words are flying out \ </td><td>like endless rain into a paper cup</td></tr>
   <tr><td>they slither while they pass \ </td><td>they slip away across the             universe</td></tr>
  </tbody>
 </table>
</body>
</html>


此代码的一个问题是您正在使用 .live 错误 - 应该直接在选择器上调用:

One problem with this code is that you're using .live wrong - it should be called directly on the selector:

$('table tr').live( /* ... */)

来自 specs :


不完全支持DOM遍历方法来查找要发送到.live()的元素。相反,.live()方法应该总是在选择器后直接调用

DOM traversal methods are not fully supported for finding elements to send to .live(). Rather, the .live() method should always be called directly after a selector

接下来,在jQuery 1.4.2上,它可能更好使用 委托

Next, on jQuery 1.4.2, it's probably better to use delegate:

$('table').delegate('tr', 'click', function(){/* ... */} );
