写在前面
在angularjs中提供了一些常用的函数，比如angular.lowercase()，angular.uppercase()，angular.isString()，angular.isNumber()。
demo
<!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml" ng-app="myapp"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title></title> <script src="../Scripts/angular.min.js"></script> <script> 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)); }); </script> </head> <body> <div ng-controller="myCtrl"> </div> </body> </html>
结果
