HtmlUnit忽略JavaScript错误？

我试图遍历一个网站，但在他们的一个页面上，我发现以下错误：

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)

我是否可以忽略这个错误？我并不特别关心日历是否正确加载。

您可以使用以下类方法：

或者将问题区域封闭在try-catch块中-

try {
   // code with error

}catch(e) {
   // handle error
}

Alexey的答案是针对HttpUnit。对于HtmlUnit，代码类似

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

我尝试使用Matthews answer，并需要使用以下方法重写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;
        }
    };

HttpUnit

如何引用

HtmlUnit

？似乎这些是不同的框架…解决方案基于设置最终字段HtmlUnit如何引用WebClient？@user12384512-HtmlUnit有自己的WebClient类-

com.gargoylesoftware.HtmlUnit.WebClient

；还要检查下面的@jseteny answer以了解其用法。

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