How to clear an angularJS array
提问by nullException
$scope.itemarray = ['A', 'B', 'C'];
this will clear the array but the ui wont be updated.
这将清除数组，但 ui 不会更新。
$scope.itemarray = [];
this works fine! why?
这很好用！为什么？
$scope.itemarray.length = 0;
回答by Petr Averyanov
$scope.itemarray.length = 0;<< this is correct. Length is read-write property.
$scope.itemarray.length = 0;<< 这是正确的。长度是读写属性。
$scope.itemarray = [];<< this creates new empty array. If you have bindings to old itemarray, they may be lost. (Html binding like ng-if="itemarray[0]"wont be lost)
$scope.itemarray = [];<< 这会创建新的空数组。如果您绑定到旧的 itemarray，它们可能会丢失。（Html 绑定之类的ng-if="itemarray[0]"不会丢失）
