还是将代码包装到事件响应函数中处理吧！给一个例子你看看。
HTML：
<!doctype html>
<html ng-app>
<head>
<script src=""></script>
<script src="script.js"></script>
</head>
<body>
<div ng-controller="EventController">
Root scope <tt>MyEvent</tt> count: {{count}}
<ul>
<li ng-repeat="i in [1]" ng-controller="EventController">
<button ng-click="$emit('MyEvent')">$emit('MyEvent')</button>
<button ng-click="$broadcast('MyEvent')">$broadcast('MyEvent')</button>
<br>
Middle scope <tt>MyEvent</tt> count: {{count}}
<ul>
<li ng-repeat="item in [1, 2]" ng-controller="EventController">
Leaf scope <tt>MyEvent</tt> count: {{count}}
</li>
</ul>
</li>
</ul>
</div>
</body>
</html>
JS：
function EventController($scope) {
$scope.count = 0;
$scope.$on('MyEvent', function() {
$scope.count++;
});
}
HTML：
<!doctype html>
<html ng-app>
<head>
<script src=""></script>
<script src="script.js"></script>

<body>
<div ng-controller="EventController">
Root scope <tt>MyEvent</tt> count: {{count}}
<ul>
<li ng-repeat="i in [1]" ng-controller="EventController">
<button ng-click="$emit('MyEvent')">$emit('MyEvent')</button>
<button ng-click="$broadcast('MyEvent')">$broadcast('MyEvent')</button>
<br>
Middle scope <tt>MyEvent</tt> count: {{count}}
<ul>
<li ng-repeat="item in [1, 2]" ng-controller="EventController">
Leaf scope <tt>MyEvent</tt> count: {{count}}
</li>
</ul>
</li>
</ul>
</div>
</body>
</html>
JS：
function EventController($scope) {
$scope.count = 0;
$scope.$on('MyEvent', function() {
$scope.count++;
});
}
