推荐答案

您可以使用 .removeAttr() ，像这样:

You can use .removeAttr(), like this:

$("#testdiv").find("table, tr, td").removeAttr("style");

请注意，尽管这只会删除内联样式，但样式表中定义的内容仍然适用.

Note though this just removes inline styles, whatever's defined in your stylesheets will still apply.

从更一般的角度来看，不需要ID来选择元素，您只需使用像我在上面的 .find() 调用中一样的元素选择器查找该<div id="testdiv">的后代的所有<table>，<tr>和<td>元素.

From a more general standpoint, an ID is never needed to select an element, you can just use an element selector like I have in the .find() call above, so for example this code looks for all <table>, <tr>, and <td> elements that are descendants of that <div id="testdiv">.
