1、实例背景

     ionic是基于AngularJS，是一个框架。根据AngularJS双向绑定变量，动态获取值。


2、实现源码

<!DOCTYPE html>
<html>
	<head>
		<meta charset="UTF-8">
		<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
		<title>ionic之简单实例</title>
		<link rel="stylesheet" href="../css/ionic.css" />
		<script type="text/javascript" src="../js/ionic.bundle.js" ></script>
		<script>
			var app = angular.module("tagApp",["ionic"]);
			app.controller("tagController",function($scope){
				$scope.username = "李海";
			});
		</script>
	</head>
	<body ng-app="tagApp" ng-controller="tagController">
		<ion-header-bar class="bar-positive">
			<label class="title">欢迎使用ionic</label>
		</ion-header-bar>
		<ion-content>
			<span>{{username}}</span>
		</ion-content>
	</body>
</html>
