javascript - 使用 jquery 预览文本

Question

我有以下html

<img src="a.jpg" /><p> This is some random text and just to test this example. This is some random text and just to test this example. This is some random text and just to test this example<p>
<br><p>This is some random text and just to test this example This is some random text and just to test this example</p>
<img src="a.jpg" />
<br><p>This is some random text and just to test this example This is some random text and just to test this example</p>

我的问题是，如果我必须只使用 jquery 来预览文本，假设我在名为 html 的变量中有这个，如何只显示文本的少数部分而忽略图像

       <div id="preview"></div>
       $("#preview").val("//display only text in the variable named html")

你可以 filter图片来自 html:

var someHtml = '....';
$('#preview').html($(someHtml).filter(':not("img")'));
