您正在使用的代码（navigator.notification.confirm）专门用于在PhoneGap移动应用程序中运行的移动平台。如果您想在将浏览器编译成应用程序之前在浏览器上测试对话框/确认消息，我建议使用混合方法来检测应用程序的环境并使用本机confirm(message)或PhoneGap特定的通知API。下面是一个为我工作的示例对象：

/**
 * The object encapsulates messaging functionality to work both in PhoneGap and 
 * browser environment. 
 * @author Zorayr Khalapyan
 * 
 */
var MessageDialogController = (function () {

    var that = {};

    /**
     * Invokes the method 'fun' if it is a valid function. In case the function
     * method is null, or undefined then the error will be silently ignored.
     *
     * @param fun  the name of the function to be invoked.
     * @param args the arguments to pass to the callback function.
     */
    var invoke = function( fun, args ) {
        if( fun && typeof fun === 'function' ) {
            fun( args );
        }
    };

    that.showMessage = function( message, callback, title, buttonName ) {

        title = title || "DEFAULT_TITLE";
        buttonName = buttonName || 'OK';

        if( navigator.notification && navigator.notification.alert ) {

            navigator.notification.alert(
                message,    // message
                callback,   // callback
                title,      // title
                buttonName  // buttonName
            );

        } else {

            alert( message );
            invoke( callback );
        }

    };

    that.showConfirm = function( message, callback, buttonLabels, title ) {

        //Set default values if not specified by the user.
        buttonLabels = buttonLabels || 'OK,Cancel';
        var buttonList = buttonLabels.split(',');

        title = title || "DEFAULT TITLE";

        //Use Cordova version of the confirm box if possible.
        if (navigator.notification && navigator.notification.confirm) {

                var _callback = function (index) {
                    if ( callback ) {
                        //The ordering of the buttons are different on iOS vs. Android.
                        if(navigator.userAgent.match(/(iPhone|iPod|iPad)/)) {
                            index = buttonList.length - index;
                        }
                        callback( index == 1 );
                    }
                };

                navigator.notification.confirm(
                    message,      // message
                    _callback,    // callback
                    title,        // title
                    buttonLabels  // buttonName
                );

        //Default to the usual JS confirm method.
        } else {
            invoke( callback, confirm( message ) );
        }

    };

    return that;

})();

希望这有帮助！如果您有任何疑问，请告诉我。
