本文通过一个示例对比了jQuery中的html()和text()方法的区别。html()方法保留HTML元素标签并将其作为字符串显示，而text()方法则只提取纯文本内容，忽略所有HTML标签。

html()显示html，包括标签
text()显示的是纯文本


<html>
<head>
<script type="text/javascript" src="/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
  $("button").click(function(){
    alert($("div").html());
    alert($("div").text());
  });
});
</script>
</head>

<body>
<div>
 <h1 id="h1">This is a heading</h1>
 <p>This is a paragraph.</p>
 <p>This is another paragraph.</p>
 <p>This is another paragraph.</p>
 <p>This is another paragraph.</p>
</div>
<button id="default">default</button>
</body>
</html>

result:
第一个alert输出
<h1 id="h1">This is a heading</h1>
<p>This is a paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another paragraph.</p>
<p>This is another paragraph.</p>

第二个alert输出
This is a heading
This is a paragraph.
This is another paragraph.
This is another paragraph.
This is another paragraph.
