jQuery正文问题-ASP.NET [英] JQuery tbody question - ASP.NET

问题描述

我有一个aspx页面，看起来像这样:

I have a aspx page that looks something like this:

<table runat="server" id="tblTEst">
  <tr id="trHeader" runat="server">

  </tr>
  <tr id="trRow1" runat="server">

  </tr>
  <tr id="trRow2" runat="server">

  </tr>
</table>

当我写我的JQuery说获得s的计数时，我需要这样做:

When I write my JQuery to say get a count of s, I need to do:

alert($('#' + strTableId).children('tbody').children('tr').length);

我的问题是，何时添加TBODY?当我做一个InnerHTML时，我看到了TBODY.我想知道这是否是ASP.NET要做的事情?

My question is when does the TBODY get added? When I do a InnerHTML, I do see the TBODY. I was wondering if this is something ASP.NET does?

编辑 感谢您的回答.如果它是由浏览器添加的，我是否需要担心在多个浏览器中测试代码以确保JQuery的兼容性?我的印象是，JQuery与所有浏览器兼容，而我不必担心在不同的浏览器上测试代码.

EDIT Thanks for the answers. If it's added by the browser, do I need to worry about testing the code in multiple browsers to ensure compatibility of JQuery? I was under the impression, JQuery is compatible with all browsers and I would'nt have to worry about testing the code on different browsers.

推荐答案

浏览器会执行此操作，这是在构建DOM时清理HTML的过程的一部分. 标准指定必须出现TR元素在TBODY，THEAD或TFOOT元素中，并且由于您均未指定任何内容，因此浏览器会为您添加一个来帮助您.

It's something the browsers do, as part of the process of cleaning up the HTML while building the DOM. The standard specifies that TR elements must occur within a TBODY, THEAD, or TFOOT element, and since you specified none of those, the browser helps you out by adding one for you.

如果您想忽略这一点，可以将表达式重写为:

If you wish to ignore this, you can re-write your expression as:

alert($('#' + strTableId).find('tr').length);

...但是，最好将行显式包装在TBODY中，以免将来造成混乱.

...But, you would do well to explicitly wrap your rows in TBODY so as to avoid confusion in the future.
