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 native 函数(用 c 编写)。

之前我使用的是 phonegap 1.0.0,应用程序在其中运行正常。但是当我将它更新到 cordova 2.0.0 时,出现错误

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

谁能帮我解决这个问题。

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);

}

return window.find.func("find",dataArray); 应该调用 native java 函数,但它给了我上述错误。

最佳答案

对我来说很好用

在 Ice-Cream Sandwich 和 GingerBread 上进行了测试(您可能需要重组以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去向。

你还需要从 cordova.exec 返回吗?

<!DOCTYPE HTML>
<html>
<head>
<title>Cordova</title>
<script type="text/javascript" charset="utf-8" src="cordova-2.0.0.js"></script>
<script type="text/javascript" charset="utf-8">

function callPlugin(type){

switch(type){

case 1:

//Func Ptr
window.echo = function(str, callback) {

cordova.exec(callback, function(err) { callback('Nothing to echo.'); }, "Echo", "echo", [str]);

};

//Func Call
window.echo("echome", function(echoValue){alert(echoValue);} );
break;

case 2:

var MyClass = function (){}; //Prototype

MyClass.prototype.echo = function(str, callback) {

cordova.exec(callback, function(err) { callback('Nothing to echo.'); }, "Echo", "echo", [str]);

};


window.echo = new MyClass();
window.echo.echo("echome2", function(echoValue){alert(echoValue);} );

//OR
//window.echo = new MyClass().echo; //Add Function to Window Object
//window.echo("echome1", function(echoValue){alert(echoValue);} ); //Call Plugin

break;
}
}

</script>
</head>
<body>
<h1>Plugin Test</h1>
<button onclick="callPlugin(1)">Call Plugin by Cordova 2.0.0 Method</button><br />
<button onclick="callPlugin(2)">Call Plugin by Cordova 1.0.0 Method</button><br />
