如何在awesomium网络控制c#中点击链接

Question

我有一个网站，有两个链接在一个div。我想点击第二个链接，它在这个div里面。以下是网站的HTML外观：

<div class="title-nav-single">
    <strong></strong>
    <a href="http://www.website.com/50665">Previous</a>
    <a href="http://www.website.com/50665/3">Next</a>
</div>

现在，我试图点击包含Next的链接。我不想得到链接的href值，我只想点击链接。以下是我到目前为止尝试过的：

private void button1_Click(object sender, EventArgs e)
{
    string xpath = GetJsSingleXpathString("//DIV[@ID=\"outbrain_widget_0\"]/preceding-sibling::DIV[3]//A[normalize-space()=\"Next\"]");
    JsFireEvent(xpath, "click");
    // webcontrol.ExecuteJavascriptWithResult("document.getElementsByClassName('title-nav-single').ElementAt(1).DomObject.click();");
}

public static string GetJsSingleXpathString(string xpath)
{
    return String.Format("document.evaluate(\"{0}\", document, null, XPathResult.FIRST_ORDERED_NODE_TYPE, null).singleNodeValue", xpath);
}

// executes javascript which fires specified event on element 
// Example: JsFireEvent("document.getElementById('my_id')", "click");
public void JsFireEvent(string getElementQuery, string eventName)
{
    webcontrol.ExecuteJavascript(@"function fireEvent(element,event) {
        var evt = document.createEvent('HTMLEvents');
        evt.initEvent(event, true, true ); // event type,bubbling,cancelable
        element.dispatchEvent(evt);
    }" + String.Format("fireEvent({0}, '{1}');", getElementQuery, eventName));
}
}

要检测是否单击了链接，需要添加target="_blank"

<a href="http://www.website.com/50665/3" target="_blank">Next</a>

并捕捉这一事件：

webControl.ShowCreatedWebView += OnShowNewView;

internal static void OnShowNewView( object sender, ShowCreatedWebViewEventArgs e )
{
    // Do sth with your link. it's in e.TargetURL
}

最后，您可以使用传统的方式打开它：

System.Diagnostics.Process.Start(e.TargetURL.ToString());

..or用它做任何你想做的事。更多信息，您可以找到这里
