我正在尝试点击此网站上的搜索按钮：

该按钮是站点左侧的搜索按钮.我使用HtmlUnitScripter附加组件为firefox生成一个类,但即使它生成了将填充表单的代码,它也不会生成将单击按钮的代码.
按下按钮后,会出现一个加载屏幕,然后显示结果.通常,下一个代码应该将结果页面返回到页面变量中
HtmlElement theElement5 = (HtmlElement) page.getElementById("ctl00_ctl00_ctl00_cph1_cph1_QuickSearchAll1_QuickFlightSearchControl1_btnSearch");
page = (HtmlPage) theElement5.click();
但它只返回填写表单的上一页.有没有一种特殊的方法来处理这个按钮,或者我找不到合适的按钮来点击？任何帮助将不胜感激.
编辑：
我使用时获得的例外
ScriptResult result = page.executeJavaScript("document.getElementById('ctl00_ctl00_ctl00_cph1_cph1_QuickSearchAll1_QuickFlightSearchControl1_btnSearch_Table').onclick()");
final Page newPage = result.getNewPage();

我认为它试图访问网站中的其他一些脚本,但它不在当前页面上. htmlunit是否仍然可以通过某些功能访问这些脚本,还是这样就可以了？
编辑2：
我在页面开头附近找到了以下脚本.这与搜索按钮有关吗？它似乎有按钮的ID,但我不确定.
</script>

解决方法
如果您无法单击按钮,请尝试此操作
HtmlElement htmlElement = page.getFirstByXPath("//*[@id=\"ctl00_ctl00_ctl00_cph1_cph1_QuickSearchAll1_QuickFlightSearchControl1_btnSearch_Table\"]/tbody/tr/td[2]");
htmlElement.click();
如果这不是你想要的,你已经处理了点击部分
我建议尝试等待页面和JavaScript加载和执行.
试试这个
webClient.waitForBackgroundJavaScript(1000);
要么
webClient.setAjaxController(new NicelyResynchronizingAjaxController());
webClient.setAjaxController(new AjaxController(){
@Override
public boolean processSynchron(HtmlPage page,WebRequest request,boolean async)
{
return true;
}
});
要么
JavaScriptJobManager manager = page.getEnclosingWindow().getJobManager();
while (manager.getJobCount() > 0) {
Thread.sleep(100);
}
