使用HTMLUnit调用JavaScript函数 [英] calling a JavaScript function with HTMLUnit

问题描述

我正在尝试调用函数 showPage（'3'）; of 此页面，用于之后的页面源代码。我尝试用 htmlUnit 这样做：

I'm trying to call the function showPage('3'); of this page, for use the page source code after. I tried to do with htmlUnit like so:

WebClient webClient = new WebClient();

webClient.waitForBackgroundJavaScriptStartingBefore(10000);
HtmlPage page = webClient.getPage("http://www.visittrentino.it/it/cosa_fare/eventi/risultati?minEventDate=09012014&maxEventDate=31012014&tp=searchForm.thismonth&ltp=gennaio");

String javaScriptCode = "showPage('3');";

ScriptResult result = page.executeJavaScript(javaScriptCode);
result.getJavaScriptResult();
System.out.println("result: "+ result);

但它不起作用。
打印出来：

But it's not working. It prints out:

结果：net.sourceforge.htmlunit.corejs.javascript.Undefined@a303147

result: net.sourceforge.htmlunit.corejs.javascript.Undefined@a303147

和其他10000个警告。我究竟做错了什么？我需要更改此站点的页面以对源代码进行一些爬行。是否有另一种方式（也许更容易）从Java代码调用jsp-function然后在页面源中导航？
感谢您的帮助，祝您度过愉快的一天。

and other 10000 warnings. What am I doing wrong? I need to change the page of this site for do some crawling on the source code. Is there another way (and maybe more easier) for calling jsp-function from Java code and then navigate in the source of the page? Thank you for any help, have a nice day.

推荐答案

您打印ScriptResult对象而不是内容页面，将SOP代码更改为result.getNewPage（）

You print the ScriptResult object not the content of the page,change the SOP code to result.getNewPage()
