HtmlUnit和Java Eclipse错误无法正常运行
[英]HtmlUnit and Java eclipse errors not running correctly
问题描述
So , I am completely new to Java this is my first program. 
因此，我对Java完全陌生，这是我的第一个程序。 I'm working with Java Eclipse using HtmlUnit and Mars i believe for my Eclipse 我正在使用HtmlUnit和Mars使用Java Eclipse，我相信我的Eclipse
and this is my current code of what i've tried 这是我目前所尝试的代码
public static void webstart(String website) throws InterruptedException
{
try (WebClient webClient = new WebClient(BrowserVersion.getDefault()))
{
label1.setText("Status: Loading Light Viewer...");
HtmlPage page = webClient.getPage(website);
label1.setText("Status: Clicking Start Viewer...");
HtmlElement start = (HtmlElement) page.getByXPath("//*[@id='main_page_offline']/div/div[3]/div/div/a");
start.click();
label1.setText("Status: Clicked...");
i=2;
while(i==2)
{
HtmlElement text = (HtmlElement) page.getByXPath("//*[@id='visio_compteur']");
String time = text.toString();
timer(time);
}
}
catch (FailingHttpStatusCodeException e)
{
e.printStackTrace();
}
catch (MalformedURLException e)
{
e.printStackTrace();
}
catch (IOException e)
{
e.printStackTrace();
} finally {
}
}
It crashes after writing Loading Light Viewer... to the label. 将Loading Light Viewer ...写入标签后，它会崩溃。
Here is the errors I'm currently getting 这是我目前遇到的错误

Looks like an error in site's JavaScript. 似乎是网站的JavaScript中的错误。
Haven't you tried this setting? 您没有尝试过此设置吗？
webClient.getOptions().setThrowExceptionOnScriptError(false);
before 之前
HtmlPage page = webClient.getPage(website);
