java – htmlunit：指定了无效或非法的选择器

我试图用htmlunit模拟登录.虽然我根据例子编写了我的代码,但我遇到了一个无聊的问题.以下是我从控制台中获取的一些消息.

runtimeError: message=[An invalid or illegal selector was specified (selector: '*,:x'         error: Invalid selector: *:x).] sourceName=[http://user.mofangge.com/Scripts/inc/jquery-1.10.2.js] line=[1640] lineSource=[null] lineOffset=[0]

这是我的代码.我没有任何用处.我不知道为什么会这样,希望得到任何帮助.

    WebClient webClient = new WebClient(BrowserVersion.CHROME);     
    webClient.getOptions().setCssEnabled(true);
    webClient.getOptions().setJavaScriptEnabled(true);
    webClient.getOptions().setThrowExceptionOnScriptError(false);
    webClient.getOptions().setTimeout(10000);

    DefaultCredentialsProvider credentialsProvider = (DefaultCredentialsProvider)webClient.getCredentialsProvider(); 
    credentialsProvider.addCredentials("username", "password"); 


    HtmlPage page = webClient.getPage(url); 
    HtmlForm loginForm = page.getFormByName("regform");         


    HtmlInput username = loginForm.getInputByName("txt_userid"); 
    HtmlInput password = loginForm.getInputByName("txt_userpw"); 

    username.setValueAttribute("username"); 
    password.setValueAttribute("password");         


    HtmlSubmitInput submit = page.getHtmlElementById("login_btn");

    webClient.waitForBackgroundJavaScript(30000);
    HtmlPage result = submit.click();


    FileWriter writer = new FileWriter("mofang.html"); 
    writer.write(result.getWebResponse().getContentAsString()); 
    writer.close(); 

解决方法:

放

webClient.waitForBackgroundJavaScript(30000);

后

HtmlPage result = submit.click()
