	<h3>ng-init初始化变量</h3>
	<div ng-init="name='aurora';age='18'">
		<p ng-bind="name+','+age"></p>
		<p>{{name+','+age}}</p>
	    <p ng-bind="name"></p>
	    <p ng-bind="age"></p>
	</div>
	<h3>ng-init初始化对象</h3>
	<div ng-init="hero={name:'aurora',role:'sup',line:'不管刮风还是下雨,太阳照常升起'}">
		<p ng-bind="hero.name+','+hero.role+','+hero.line"></p>
	    <p ng-bind="hero.name"></p>
	    <p ng-bind="hero.role"></p>
	    <p ng-bind="hero.line"></p>
	</div>
	<h3>ng-init初始化数组</h3>
	<div ng-init="heros=['曙光女神','堕落天使','魂锁典狱长']">
		<p ng-bind="heros[0]+','+heros[1]+','+heros[2]"></p>
	    <p ng-bind="heros[0]"></p>
	    <p ng-bind="heros[1]"></p>
	    <p ng-bind="heros[2]"></p>
	</div>
	
	<h3>ng-controller控制器</h3>
	<div ng-controller="contr-2">
	    First Name: <input type="text" ng-model="firstName">
	    Last Name: <input type="text" ng-model="lastName">
	    Full Name : <span>{{firstName + "," + lastName}}</span>
	    Full Name : <span ng-bind="firstName + ',' + lastName"></span>    
	</div>

	<h3>ng-repeat遍历无重复集合</h3>
	<div ng-init="names=[1,2,3]">
	  <ul>
	    <li ng-repeat="x in names">
	      {{x}}
	    </li>
	  </ul>
	</div>
	<h3>ng-repeat遍历重复集合</h3>
	<div ng-init="number=[1,2,2,3]">
	  <ul>
	    <li ng-repeat="x in number track by $index">
	      {{x}}
	    </li>
	  </ul>
	</div>
	<h3>ng-repeat遍历对象</h3>
	<div ng-controller="contr-3">
		  <ul>
		    <li ng-repeat="(key,value) in object track by $index">
		      {{key+":"+value}}
		    </li>
		  </ul>
	</div>
	<h3>ng-repeat遍历对象(按原有顺序)</h3>
	<div ng-controller="contr-4">
		  <ul ng-repeat="obj in obJS ">
		    <li ng-repeat="(key,value) in obj ">
		      {{key+":"+value}}
		    </li>
		  </ul>
	</div>
	<h3>ng-repeat遍历对象(属性详解)</h3>
	<table ng-controller="contr-5">
		<tr ng-repeat="(key, value) in objs ">
			<td>学号:
				<span ng-bind="$index"></span>
			</td>
			<td>
				<span ng-bind="key"></span>:
				<span ng-bind="value"></span>
			</td>
			<td>是否为奇数?
				<span ng-bind="$odd"></span>
			</td>
			<td>是否为偶数?
				<span ng-bind="$even"></span>
			</td>
			<td>排行是老大?
				<span ng-bind="$first"></span>
			</td>
			<td>排行最小?
				<span ng-bind="$last"></span>
			</td>
			<td>排行中间?
				<span ng-bind="$middle"></span>
			</td>
		</tr>
	</table>
	<h3>ng-repeat start/end</h3>
	<div ng-controller="contr-6">
		<div ng-repeat-start="(key,value) in objs">
			<p>学号:
				<span ng-bind="$index"></span>
			</p>
			<p>
				<span ng-bind="key"></span>:
				<span ng-bind="value"></span>
			</p>
		</div>
		<div ng-repeat-end></div>
	</div>
