如何在awesomium webcontrol c#中点击link

Question

我的网站在 div 中有两个 link。我想点击 div 里面的第二个 link。这是网站 HTML 的样子：

<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 link。我不想获得 link href 值，我只想单击 link。到目前为止，这是我尝试过的方法：

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 link 是否被点击，您需要添加 target="_blank":

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

并捕获此事件：

webControl.ShowCreatedWebView += OnShowNewView;

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

终于可以用传统方式打开了：

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

..或者用它做任何你想做的事。您可以找到更多信息 here
