只有在页面完全加载后才填充文档 [英] Populate doc only after the page is completely loaded

问题描述

我从特定网站检索数据。 < sup> 中的< a> 仅在页面完全加载后才可用iejavascript将<

I am retrieving data form a certain website. The <a> inside <sup> is available only after the page is completely loaded i.e.javascript adds the <a> tag to the page.

<table>
<tr>
<td class="left ">
<a href="reference" >Refer</a>see this
<sup class="super"><a href=​"#src1" onclick=​"dosomething;​" title=​"1" >​1​</a>​</sup>
</td>
<td class="td_right2" style="padding-top: .25em"></td>
</tr>
..

</table>

所以，当我做的时候

Document doc=JSoup.connect(...).userAgent(...).get();

文件不包含< a> 标签。
我如何确保文档也使用'a'标签填充.JSoup中的任何函数与JQuery中的 .ready 类似？

The doc doesnot contain the <a> tag. How do I make sure that the doc gets populated with 'a' tag as well.Is there any function in Jsoup similar to .ready in JQuery?

推荐答案

Jsoup是一个HTML解析器，而不是webbrowser。像大多数HTML解析器一样，Jsoup不执行任何JavaScript代码。

Jsoup is a HTML parser, not a webbrowser. Like as most HTML parsers, Jsoup doesn't execute any JavaScript code.

您需要一个可以执行JavaScript的HTML解析器。 就是这样，它是一个无GUI界面的浏览器，专为单元测试而设计，能够执行包含JavaScript的页面在可能修改HTML DOM树的网页中。您可以尝试使用它。

You need instead a HTML parser which can execute JavaScript. HtmlUnit is such one, it's a GUI-less webbrowser designed for unit-testing purposes and is capable of executing JavaScript contained in the webpage which may modify the HTML DOM tree. You could try using it instead.
