HtmlUnit - 处理错误 Ajax Jquery
HtmlUnit - Error in processing Ajax Jquery
我使用 htmlUnit 处理了 div 到 Ajax 的大量内容。我已经尝试了所有方法，但在单击按钮后我无法获得包含更改的新页面。
似乎下面脚本中的代码不起作用。
$（文档）.ready（函数（）{
...
});
请帮助我。谢谢
我的部分代码：
WebClient client = new WebClient(BrowserVersion.FIREFOX_60);
client.getOptions().setJavaScriptEnabled(true);
client.getOptions().setThrowExceptionOnScriptError(false);
client.getOptions().setCssEnabled(false);
client.setAjaxController(new NicelyResynchronizingAjaxController());
HtmlPage paginaDePesquisaLicitacao = client.getPage("url");
client.waitForBackgroundJavaScript(5 * 1000);
HtmlForm 表单 = (HtmlForm) paginaDePesquisaLicitacao.getElementById("licitacaoPesquisaIdentificadorForm");
HtmlTextInput inputNumeroLicitacao = form.getInputByName("numeroLicitacao");
inputNumeroLicitacao.type(login);
HtmlPage paginaCabecalhoLicitacao = ((HtmlSubmitInput) form.getInputByName("pesquisar")).click();
client.waitForBackgroundJavaScript(10000);
Thread.sleep(10*1000);
System.out.println(paginaCabecalhoLicitacao.asXml());

看起来您使用的是旧版本的 HtmlUnit。请尝试使用最新版本，如果您仍然遇到问题，请在 github 上提出问题。
