我正在尝试单击此站点中的搜索按钮：http ://www.amadeusepower.com/trek/portals/trek/default.aspx?Culture=en-US

但它显然无法点击它，因为返回的页面与旧页面相同。它需要返回一个显示此搜索结果的页面。

我尝试了 htmlunitscripter，但它似乎不知道我点击了该按钮并且它没有为其生成代码。我试过了 ：

HtmlElement theElement5 = (HtmlElement) page.getElementById("ctl00_ctl00_ctl00_cph1_cph1_QuickSearchAll1_QuickFlightSearchControl1_btnSearch");
page = (HtmlPage) theElement5.click();

但它不起作用（返回旧页面）。我在 selenium 中尝试了下一个代码并且它工作但我不能使用 selenium，因为当我尝试在 Web 服务中使用它时它引起的问题。

WebElement searchbutton = driver.findElement(By.id("ctl00_ctl00_ctl00_cph1_cph1_QuickSearchAll1_QuickFlightSearchControl1_btnSearch"));
searchbutton.click();

如何在 htmlunit 中访问此按钮？我没有尝试 xpath，因为我不知道如何使用它获取元素。有人可以看看该网站并提出解决方案以达到并单击此按钮吗？

编辑：

当我尝试这个时

page.executeJavaScript("var elem = document.getElementById('ctl00_ctl00_ctl00_cph1_cph1_QuickSearchAll1_QuickFlightSearchControl1_btnSearch'); elem.click();");

它抛出这个异常。

显然它找不到元素的点击功能。还能做什么？

您可以尝试通过 js 执行调用，看看它是否可以这样工作：

JS 应该是这样的：

var elem = document.getElementById('ctl00_ctl00_ctl00_cph1_cph1_QuickSearchAll1_QuickFlightSearchControl1_btnSearch'); elem.click();
