在Angularjs中this的指当前的scope。
<a class=" ng-click="remove(this)"></a> <!--this指的是a标签作用域下的scope--> <script> app.controller(‘myCtrl‘,function($scope){ $scope.remove = function (scope) { scope.remove(); }; }); </script>
来自知乎的解释，https://www.zhihu.com/question/35780175
<div ng-click="change()">{{value}}</div>
$scope.change = function(){
this.value = ‘new value‘;
//等价于$scope.value = ‘new value‘
}
<div ng-click="change()" ng-repeat="item in items">{{item.value}}</div>
$scope.change = function(){
this.item.value = ‘new value‘;
//由于是ng-repeat出来的，所以这里this指向的scope是上面那个案例中$scope的子集。
//即this.$parent === $scope;
