我正在尝试构建一个手电筒应用程序,但它在我的设备上无效,在Firebug中我有一个奇怪的错误:
ReferenceError: cordova is not defined
cordova.addConstructor(Flashlight.install);
我使用https://build.phonegap.com/plugins/294插件
我的代码index.html
<div id="button2" class="button1">Click!</div>
我的代码flashlightexec.js
$("#button2").live('click', function(){
window.plugins.flashlight.available(function(isAvailable) {
if (isAvailable) {
window.plugins.flashlight.switchOn();
alert("ok");
} else {
alert("Flashlight not available on this device");
}
});
});
插件代码:
function Flashlight() {
// track flashlight state
this._isSwitchedOn = false;
}
Flashlight.prototype = {
available: function (callback) {
cordova.exec(function (avail) {
callback(avail ? true : false);
}, null, "Flashlight", "available", []);
},
switchOn: function (successCallback, errorCallback) {
this._isSwitchedOn = true;
cordova.exec(successCallback, errorCallback, "Flashlight", "switchOn", []);
},
switchOff: function (successCallback, errorCallback) {
this._isSwitchedOn = false;
cordova.exec(successCallback, errorCallback, "Flashlight", "switchOff", []);
},
toggle: function (successCallback, errorCallback) {
if (this._isSwitchedOn) {
this.switchOff(successCallback, errorCallback);
} else {
this.switchOn(successCallback, errorCallback);
}
}
};
Flashlight.install = function () {
if (!window.plugins) {
window.plugins = {};
}
window.plugins.flashlight = new Flashlight();
return window.plugins.flashlight;
};
cordova.addConstructor(Flashlight.install);
我应该改变什么来使手电筒工作?也许还有另一种解决方案&amp;
答案 0 :(得分:1)
我认为你需要在包含插件.js文件之前在index.html中添加对cordova.js的引用。另外,等待deviceready事件触发。
