Question

使用HtmlUnit我可以为网页获取此Image元素

 <pre> <a onclick="return OnSubmitValidateSignUp();return ValidEmail();" id="lnkSave"    tabindex="10" class="create" href="javascript:__doPostBack('lnkSave','')"></a> </pre>

使用

     <i> HtmlAnchor button = (HtmlAnchor) currentPage.getByXPath("//* [@id=\"lnkSave\"]").get(0);     
System.out.println(" anchor "+ button.getId());</i>

但是当我发现button.click();后发生错误。

我该如何解决这个问题？

这是一个javascript问题。看来你有一些javascript附加到按钮的OnClick事件。首先尝试禁用JS，如果可能的话。第二次尝试看看这个答案：HtmlUnit is throwing Out Of Memory and maybe leaking memory，它可能会有帮助。

使用HtmlUnit单击锚点时发生错误
