常用自定义服务方法.md

app.config(['$provide', function($provide) {
			//$('p').addClass("wsscat");
			angular.element(document.querySelector('p')).addClass("wsscat").css('backgroundColor','yellow');
			$provide.service('Math3', function() {
				this.addd = function(a, b) {
					return a + b;
				};
				this.multipyy = function(a, b) {
					return a * b
				}
			})
			$provide.factory('Math4', function() {
				var obj = {
					add4(a, b) {
						return a + b;
					},
					multipy4(a, b) {
						return a * b
					}
				}
				return obj;
			})
		}])
app.factory('Math', function() {
		var obj = {
			add: function(a, b) {
				return a + b;
			},
			multipy: function(a, b) {
				return a * b
			},
			num:1,
			str:"abc"
		}
		return obj;
	})
//service其实一个构造器，但我们注入这个服务的时候，就会自动帮我们new，创建这个对象
app.service('Math2', function() {
	this.add = function(a, b) {
		return a + b;
	};
	this.multipy = function(a, b) {
		return a * b
	};
	this.num=1;
	this.str="abc";
})
//constant定义常量
app.constant('consta','wsscat is cat')

//定义函数，字符串，数字等等，可更改值
app.value('name',{
			add: function(a, b) {
				return a + b;
			},
			multipy: function(a, b) {
				return a * b
			},
			num:1,
			str:"abc"
		})
app.service('change',()=>{
	return {
		text(){
			return "wsscat"
		},
		number:1
	}
})
