我在 index.js 中编写了一个测试 javascript 代码，它是一个普通的 alert()，当我在 android 上测试涟漪时它工作正常，当我在我的 Windows Phone 上测试它时它显示

Unhandled exception at line 16, column 13 in
ms-appx://io.cordova.myapp16ff10/www/scripts/index.js

0x800a1391 - JavaScript runtime error: 'alert' is undefined

index.js

(function () {
    "use strict";

    document.addEventListener( 'deviceready', onDeviceReady.bind( this ), false );

    function onDeviceReady() {
        // Handle the Cordova pause and resume events
        document.addEventListener( 'pause', onPause.bind( this ), false );
        document.addEventListener('resume', onResume.bind(this), false);

        document.getElementById("btnTakePhoto").onclick = function () {
            alert("button working fine!");
        };

        // TODO: Cordova has been loaded. Perform any initialization that requires Cordova here.
    };

    function onPause() {
        // TODO: This application has been suspended. Save application state here.
    };

    function onResume() {
        // TODO: This application has been reactivated. Restore application state here.
    };
} )();

alert原因是因为在 Windows Phone 7 和 8中没有内置支持。请改用 PhoneGap 的Notification API，并有这样的东西：

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

function onDeviceReady() {
    window.alert = window.alert || navigator.notification.alert;
    alert('button working fine!');
}
