[英]HtmlUnit Javascript error when getting Page

 原文  2015-09-20 16:38:54  1   1    javascript/ java/ html/ htmlunit

问题描述

I'm new to interacting with websites in Java, and I am having trouble getting a webpage with htmlUnit 2.18. 我是第一次接触Java中的网站，但是在使用htmlUnit 2.18获取网页时遇到了麻烦。 I've tried to change the URL to other websites(like google), and those pages have loaded. 我试图将URL更改为其他网站（例如google），并且这些页面已加载。 But when I try to load the page my program needs I get the attached errors. 但是，当我尝试加载页面时，我的程序需要我得到附件错误。 I've steped through my program and it is breaking on the line final HtmlPage loginPage = browser.getPage(LOGIN_PAGE); 我已经完成了程序，它在final HtmlPage loginPage = browser.getPage(LOGIN_PAGE);行上final HtmlPage loginPage = browser.getPage(LOGIN_PAGE);

Try this 尝试这个 

browser.getOptions().setThrowExceptionOnScriptError(false);

after 后 

browser = new WebClient(BrowserVersion.CHROME);

To Ahmed Ashour: maybe it is a bad default value? 对艾哈迈德·阿瑟（Ahmed Ashour）：也许这是一个不好的默认值？
