Question

为什么这只适用于＆＃34; body＆＃34;？我尝试使用head和id标签但是一旦我将它更改为它就无法工作。即便如此，它仅适用于空白的html，但不适用于此文件。

适合发布quota.text的文本，以适应发布quota.text以适合发布quota.text以适应发布quota.text以适应发布quota.text以适应发布配额。

Answer 1

因为头标记只包含标记

<title> 
<style>
<base>
<link>
<meta>
<script>
<noscript>

如果你附加其他标签，它会被添加到正文

为什么$（文件）.ready（function（）{$（＆＃34; body＆＃34;）。prepend（＆＃39; <p> I \＆＃39; ma段落！</p>＆＃39 ）;}）;
