HtmlUnit忽略JavaScript错误？

我试图通过一个网站,但在他的一个页面上,我得到这个错误：

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)

有没有反正我可以忽略这个错误？我不是特别关心日历是否正确加载.

解决方法

Alexey的答案是针对HttpUnit.对于HtmlUnit,代码是类似的

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