Question

嗨Iam windows phone fresher。任何人都可以告诉我如何在Phonegap（windows mobile）的javascript中调用C＃方法。谢谢。

我收到以下错误。

错误：“无法找到command :: MyCommand”。

这是我的代码Behind file

using System;
using System.Collections.Generic;
using System.Linq; using System.Net;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Animation;
using System.Windows.Shapes;
using Microsoft.Phone.Controls;
using System.IO;
using System.Windows.Media.Imaging;
using System.Windows.Resources;
using WP7CordovaClassLib.Cordova.Commands;
namespace CSharpToJS
{
public partial class MainPage : PhoneApplicationPage
{
    // Constructor
    public MainPage()
    {
        InitializeComponent();
    }

    private void GapBrowser_Loaded(object sender, RoutedEventArgs e)
    {

    }

}
namespace WP7GapClassLib.PhoneGap.Commands
{
    public class MyCommand : BaseCommand
    {
        public void DoThis(string args)
        {
            // TODO: 
        }
    }
}
}

这是我的Index.html文件：

<!DOCTYPE html>
<html>
<head>
<meta name="viewport" content="width=device-width, height=device-height, initial-    scale=1.0, maximum-scale=1.0, user-scalable=no;" />
<meta http-equiv="Content-type" content="text/html; charset=utf-8" />
<title>Cordova WP7</title>
<link rel="stylesheet" href="master.css" type="text/css" media="screen" title="no title" charset="utf-8" />
<script type="text/javascript" charset="utf-8" src="cordova-1.5.0.js"></script>
<script type="text/javascript">
    document.addEventListener("deviceready", onDeviceReady, false);
    // once the device ready event fires, you can safely do your thing! -jm
    function onDeviceReady() {
        document.getElementById("welcomeMsg").innerHTML += "Cordova is ready! version=" + window.device.cordova;
        console.log("onDeviceReady. You should see this message in Visual Studio's output window.");
        var args = { "message": "whatever" };
        Cordova.exec(null, null, "MyCommand", "DoThis", args);
    }
  </script>
 </head>
  <body>
 <h1>
    Hello Cordova</h1>
<div id="welcomeMsg">
</div>
</body>
</html>

Answer 1

您应该可以使用plugin architecture和PhoneGap.exec()方法完成此操作。

在c＃中创建一个继承自BaseCommand的类（您还必须使用此特定命名空间）：

namespace WP7GapClassLib.PhoneGap.Commands
{
    public class MyCommand : BaseCommand
    {
      public void DoThis(string args)
      {
        // TODO: 
      }
    }
}

从Javascript调用此方法：

var args = {"message":"whatever"};    
PhoneGap.exec(null, null, "MyCommand", "DoThis", args);

您可以将Notify方法与ScriptNotify事件处理程序结合使用，详见以下博客文章： -
