1. Problem background

A dependency injection unique to AngularJS. When an object is created, it needs to depend on another object.

2. Implementation source code

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<title>AngularJS之依赖注入（实例一）</title>
		<script src="http://apps.bdimg.com/libs/angular.js/1.4.6/angular.min.js"></script>
		<style>
			body,html{
				font-family: "微软雅黑";
				font-size: 12px;
				font-feature-settings: on;
			}
			.showContent{
				width: 200px;
				padding: 10px;
				margin: 10px;
				border: 1px dashed #2AABD2;
			}
		</style>
		<script>
			var app = angular.module("reApp",[]);
			app.config(function($controllerProvider){
				$controllerProvider.register("reCon",["$scope",function($scope){
					$scope.content = "";
					$scope.clickShow = function(){
						$scope.content = "showContent";
						$scope.showContent = "依赖注入";
					};
				}]);
			});
		</script>
	</head>
	<body ng-app="reApp">
		<p ng-controller="reCon">
			<button type="button" ng-click="clickShow();">依赖注入</button><br><br>
			<label class="{{content}}">{{showContent}}</label>
		</p>
	</body>
</html>
