如何解决HtmlUnit-单击链接时执行JavaScriptAjax错误
我是htmlunit的一个获取信息的页面，该页面使用javascript（ajax）e意识到每次链接中的html代码变化很大。但是我会遵循文档中的所有内容，并且无法执行ajax工作并获取更改页面。这对我的工作非常重要。请帮帮我！
我正在使用htmlunit版本2.43
我的零件代码：
WebClient client = new WebClient(BrowserVersion.FIREFOX_68);
client.getOptions().setJavaScriptEnabled(true);
client.getOptions().setThrowExceptionOnScriptError(false);
client.getOptions().setCssEnabled(false);
client.setAjaxController(new NicelyResynchronizingAjaxController());
// Here a get Page paginaAfterConsultaIdentificador
HtmlAnchor linkConsultaLote = (HtmlAnchor) paginaAfterConsultaIdentificador.getByXPath("//ul[@class='dropdownBB_content']//a").get(1);
HtmlPage paginaAfterConsultaIdentificadorCaptcha= linkConsultaLote.click();
client.waitForBackgroundJavaScript(5 * 1000);
//But the page doesn't change. I don't know if the error is in the javascript or css
System.out.println(paginaAfterConsultaIdentificadorCaptcha.asXml());
单击锚点后，在日志中显示错误：
