        var app = angular.module('myapp', []);
        app.controller("myCtrl", function ($scope) {
            //控制器
            var name = "WOLFY";
            //转换字符串为小写
            var lower = angular.lowercase(name);
            console.log(lower);
            //转换字符串为大写
            var upper = angular.uppercase(lower);
            console.log(upper);
            //判断给定的对象是否为字符串，如果是返回 true。
            console.log(angular.isString(name));
            //判断给定的对象是否为数字，如果是返回 true。
            console.log(angular.isNumber(name));
            //是否是undefined
            console.log(angular.isUndefined(name));
            //是否是array
            console.log(angular.isArray(name));
            //是否为date
            console.log(angular.isDate(name));
            //是否defined
            console.log(angular.isDefined(name));
            //是否是element
            console.log(angular.isElement(name));
            //是否是function
            console.log(angular.isFunction(name));
            //是否是object
            console.log(angular.isObject(name));

            console.log(angular.isPrototypeOf(name));
