关于$filter的自定义过滤器。要是定义在moduler内部使用自定义函数的方式，那么传入该函数的是object。要是定义成filter的话，则传入filter的则是array。
<div ng-app="myApp" ng-controller="namesCtrl">
<ul>
<li ng-repeat="x in names | filter:myFilter1">
<!-- 传入object -->
{{x}}
</li>
</ul>
<ul>
<li ng-repeat="x in names | myFilter2">
<!-- 传入array -->
{{x}}
</li>
</ul>
</div>
<script>
angular.module('myApp', []).controller('namesCtrl', function($scope,$filter) {
$scope.index = 2;
$scope.size = 3;
$scope.names = [
{name:'11'},
{name:'22'},
{name:'33'},
{name:'44'},
{name:'55'},
{name:'66'},
{name:'77'}
];
$scope.myFilter1 = function(data){
console.log(data);
}
}
}).filter('myFilter2',function($filter){
return function(data){
console.log(data);
}
});
angular.module('demo',[])
</script>
