Web瀏覽器找到錨點和autoclick在c＃

Question

我正在創建一個工具，我已經使用C＃瀏覽器控件，它自動登錄IRCTC並預訂機票。一切工作正常，除了一頁。我不能夠通過瀏覽器點擊，我怎麼能找到錨，並通過點擊C＃browser.Below是HTML：

在這裏，我想通過瀏覽器下方點擊。我不能夠找到下面主播：請幫我：

<a onclick="availFareEnq(this,'12141','Thu Jul 03 00:00:00 IST `2014','SL','CSTM','JBP',true)"> SL</a>. 

Answer 1

你可以注入HTML成在瀏覽器中控制和負載的jQuery加載的頁面，然後注入的JavaScript用了jQuery以同樣的方式找到錨標籤並點擊它。

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); 

然後，當你想點擊它，做

idOfBrowserControl.Document.InvokeScript("clickAnchor"); 

你不必注入jQuery的，我只是這樣做，因爲我使用jQuery的一切......它更容易。
