在Java中运行JavaScript [英] Run JavaScript in Java

问题描述

我有一个javaScript标记：

 <！ - 开始ParsTools.com祷告时间代码 - > 
< script type =text / javascriptlanguage =javascriptsrc =http://www2.parstools.com/oghat/oghatwhite.php>< / script> 
< script language =javascript> 
 var CurrentDate = new Date（）; 
 var JAT = 1; 
 function pz（）{}; 
 init（）; 
 document.getElementById（cities）。selectedIndex = 12; 
 coord（）; 
 main（）; 
< / script> 
 <！ - 结束祈祷时间代码 - > 
  

我想在java中运行此脚本并接收服务器发送的html文档作为响应。我怎样才能做到这一点？我还需要解析收到的文档并提取一些特殊的标签。

谢谢。

解决方案

  WebClient htmlunit = new WebClient（）;我们知道最简单的方法就是使用HtmlUnit。 
 HtmlPage page = htmlunit.getPage（http://www.google.com）; 
 
 //执行javascript并获取新页面
 page = page.executeJavaScript（< JS code here>）。getNewPage（）;

I have a javaScript tag:

<!-- Begin ParsTools.com Prayer Times Code -->
<script type="text/javascript" language="javascript" src="http://www2.parstools.com/oghat/oghatwhite.php"></script>
<script language="javascript">
    var CurrentDate= new Date(); 
    var JAT= 1;  
    function pz() {};
    init();
    document.getElementById("cities").selectedIndex=12;
    coord();
    main();
</script>
<!-- End Prayer Times code -->

I want to run this script in java and receive the html document that server sends in response. How can I do this? I also need to parse the received document and extract some special tags.

thank you.

解决方案

The easiest way I know is using HtmlUnit.

WebClient htmlunit = new WebClient();
HtmlPage page = htmlunit.getPage("http://www.google.com");

//executing the javascript and getting the new page
page = page.executeJavaScript("<JS code here>").getNewPage();
