calling a JavaScript function with HTMLUnit
提问by Der Fede
I'm trying to call the function showPage('3');of this page, for use the page source code after. I tried to do with htmlUnitlike so:
我想调用的函数showPage('3');的这个页面，为以后使用页面的源代码。我试图htmlUnit这样做：
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<p=gennaio");
String javaScriptCode = "showPage('3');";
ScriptResult result = page.executeJavaScript(javaScriptCode);
result.getJavaScriptResult();
System.out.println("result: "+ result);
But it's not working. It prints out:
但它不起作用。它打印出：
result: net.sourceforge.htmlunit.corejs.javascript.Undefined@a303147
结果：net.sourceforge.htmlunit.corejs.javascript.Undefined@a303147
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.
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抓取。是否有另一种方法（也许更简单）从 Java 代码调用 jsp-function 然后在页面的源代码中导航？感谢您的任何帮助，祝您有美好的一天。

You print the ScriptResult object not the content of the page,change the SOP code to result.getNewPage()
您打印的是 ScriptResult 对象而不是页面的内容，将 SOP 代码更改为 result.getNewPage()
