我正在创建一个我使用c#浏览器控件的工具，它会自动登录IRCTC并预订机票。一切正常，除了一页。我不能通过浏览器点击，我怎么能找到锚并通过c#浏览器点击。下面是HTML:

。我找不到下面的锚:请帮助我:
<a onclick="availFareEnq(this,'12141','Thu Jul 03 00:00:00 IST `2014','SL','CSTM','JBP',true)"> SL</a>.
你可以在浏览器控件加载的页面中注入html并加载jquery，然后注入javascript，就像使用jquery找到锚标记并点击它一样。
HtmlElement head = idOfBrowserControl.Document.GetElementsByTagName("head")[0];
HtmlElement script1 = idOfBrowserControl.Document.CreateElement("script");
script.SetAttribute("type", "text/javascript");
script.SetAttribute("src", "//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js");
HtmlElement script2 = idOfBrowserControl.Document.CreateElement("script");
script.SetAttribute("type", "text/javascript");
script.InnerHtml = "function clickAnchor() { $($('a', '#avlAndFareForm:trainbtwnstns:6:j_idt311')[0]).click();}}";
head.AppendChild(script1);
head.AppendChild(script2);
当你想点击它时，点击
idOfBrowserControl.Document.InvokeScript("clickAnchor");
你不需要注入jQuery，我这样做只是因为我使用jQuery的一切…它是容易。
