htmlunit忽略JavaScript错误

Question

我正在尝试通过网站穿越，但是在他们的一个页面上，我会遇到此错误：

EcmaError: lineNumber=[671] column=[0] lineSource=[null] name=[TypeError] sourceName=[https://reservations.besodelsolresort.com/asp/CalendarPopup.js] message=[TypeError: Cannot read property "parentNode" from undefined (https://reservations.besodelsolresort.com/asp/CalendarPopup.js#671)]
com.gargoylesoftware.htmlunit.ScriptException: TypeError: Cannot read property "parentNode" from undefined (https://reservations.besodelsolresort.com/asp/CalendarPopup.js#671)

无论如何，我可以忽略这个错误吗？我不特别关心日历是否正确加载。

Answer 1

alexey的答案是针对httpunit的。对于htmlunit，代码相似

WebClient client = new WebClient();
client.getOptions().setThrowExceptionOnScriptError(false);

Answer 2

我尝试使用matthews答案，并且需要使用以下方式覆盖newwebclient（）方法：

    HtmlUnitDriver driver = new HtmlUnitDriver(true) {
        @Override
        protected WebClient newWebClient(BrowserVersion version) {
            WebClient webClient = super.newWebClient(version);
            webClient.getOptions().setThrowExceptionOnScriptError(false);
            return webClient;
        }
    };

Answer 3

您可以使用以下方法 httpunitoptions class> class：

//change the scriptingEnabled flag
static void setScriptingEnabled(boolean scriptingEnabled)
// Determines whether script errors result in exceptions or warning messages.
static void setExceptionsThrownOnScriptError(boolean throwExceptions)

或将问题区域包围在try -catch块中 -

try {
   // code with error
}catch(e) {
   // handle error
}
