如何使用webkit使js函数与c#交互？,c#,mono,webkitgtk,C#,Mono,Webkitgtk,我用运行在mono c#中的webkit制作了一个webbrowser。我希望允许页面在浏览器中调用函数，然后浏览器根据传递的参数执行操作。我似乎做不到 html页面是下一个页面 <html> <head> <title>ola</title> </head> <body> <button onclick="window.external.Test('called from script code');">tes

我用运行在mono c#中的webkit制作了一个webbrowser。我希望允许页面在浏览器中调用函数，然后浏览器根据传递的参数执行操作。我似乎做不到

html页面是下一个页面

<html>
<head>
<title>ola</title>
</head>
<body>
<button onclick="window.external.Test('called from script code');">test</button>
</body>
</html>

如果你想要c#项目，它就在这里

提前感谢。

您需要从旧的webview类派生一个新的webview类，并覆盖：

public class MyDerived: WebView
{
...

    public const string COM_COMMAND_INIT = "http://mypresetcommand/?";
    protected override void OnResourceRequestStarting(WebKit.WebFrame web_frame, WebKit.WebResource web_resource, WebKit.NetworkRequest request, WebKit.NetworkResponse response)
    {
        // check if this is a command
        if (request.Uri.ToLower().StartsWith(COM_COMMAND_INIT))
        {
            // this is a com command. Responding with responce.
            string cmnd = web_resource.Uri.Substring(COM_COMMAND_INIT.Length);
            // HANDLE COMMAND HERE.
            return;
        }
        base.OnResourceRequestStarting(web_frame, web_resource, request, response);
    }
}

完成此操作后，只需在网页内对C#应用程序进行ajax调用即可。将“myresetcommand/？”替换为您自己的不可检查url。您可以通过WebView中的ExecuteScript进行响应
