ng-controller 重复指定
<div ng-controller="EventController">
Root scope
<tt>My Event</tt> count: {{count}}
<ul>
<li ng-repeat="i in [1]" ng-controller="EventController">
<button ng-click="$emit('MyEvent')">
$emit('MyEvent');{{i}}
</button>
<button ng-click="$broadcast('MyEvent')">
$broadcast('MyEvent'){{i}}
</button>
<br />
Middle Scope
<tt>MyEvent</tt> count: {{count}}
<ul>
<li ng-repeat="item in [1, 2]" ng-controller="EventController">
Left scope {{item}}
<tt>MyEvent</tt> count: {{count}}
</li>
</ul>
</li>
</ul>
</div>为什么在ng-repeat 的li标签中还要写一个一样ng-controller呢？在根div中不是已经制定ng-controller了吗？
