cordova 2.0.0給出未捕獲的TypeError：對象0沒有方法'func'

我已經在cordova2.0.0中創建了一個應用程序，在cordova的幫助下，我從Java腳本調用本機函數（用c編寫）。cordova 2.0.0給出未捕獲的TypeError：對象0沒有方法'func'

以前我是用的PhoneGap 1.0.0做其中的應用程序工作properly.but當我把它更新到2.0.0科爾多瓦，我得到的錯誤

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

任何一個可以請幫我出了這個問題。

代碼我的.html文件中：

<!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

：

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);  

}

行return window.find.func("find",dataArray);被suppossed調用本地Java功能，但它給我上面的錯誤。

工作正常，我

測試上的冰激凌三明治和薑餅（您可能需要進行重組去除開關和有你喜歡的任何選項）

嘗試調試您的版本與警報看到，直到其中它走了。

您是否還需要從cordova.exec返回？
