Question

我在cordova2.0.0中创建了一个应用程序，我在cordova的帮助下从java脚本调用本机函数（用c编写）。

之前我正在使用phonegap 1.0.0，其中应用程序正常运行。但是当我将其更新为cordova 2.0.0时，我收到错误

08-07 15:24:12.527: I/Web Console(855): JSCallback Error: Request failed. at file:///android_asset/www/cordova-2.0.0.js:3698
08-07 15:22:27.815: E/Web Console(855): Uncaught TypeError: Object 0 has no method 'func' at file:///android_asset/www/file.js:359

任何人都可以帮我解决这个问题。

我的.html文件的代码：

<!DOCTYPE html>
 <head>
   <script type="text/javascript" charset="utf-8" src="cordova2.0.0.js"></script>
   <script type="text/javascript" charset="utf-8" src="find.js"></script>
   <script type="text/javascript">

      function js_find(fthisval){   

        ws_find(socket,js_found);           

      }
      function js_found(retval){    

       alert(retval);           

      }
      function onBodyLoad(){        

            document.addEventListener("deviceready",onDeviceReady,false);

      }

       function onDeviceReady()
      {

            document.getElementById('d1').style.visibility = "visible";

        }   
   </script>    
 </head>
 <body onload="onBodyLoad()">
 <div id="d1" style="visibility:hidden">
    <button id="b1" onclick="js_find("ram")">Find it plz</button><br />
     </div>
</body>

在find.js中

：

var Find = function() {};

Find.prototype.func = function(funcname,funcdata) { 

return cordova.exec(
  null,                 
  null,                 
  'findPlugin',     
  funcname,            
  funcdata);            
};
window.find = new Find();

function ws_find(name, param, callback){

     if(undefined == callback){

            var dataArray = [param, param, name];   

    }
    else{

        var dataArray = [callback, callback, name, param];

     }

     alert("Calling plugin function find with \r\n"+dataArray);       
     return window.find.func("find",dataArray);     

}

线return window.find.func("find",dataArray);被称为调用本机java函数，但它给了我上述错误。

对我来说很好用

在冰淇淋三明治和GingerBread上进行测试（您可能需要重新构建移除开关并选择您喜欢的任何选项）

尝试使用警报调试您的版本以查看它的位置。

您还需要从cordova.exec返回吗？

cordova 2.0.0给出了Uncaught TypeError：对象0没有方法＆＃39; func＆＃39;
