rated 0 times [ 165] [ 6] / answers: 1 / hits: 91846 / 9 Years ago, wed, april 22, 2015, 12:00:00

 $scope.itemarray = ['A', 'B', 'C'];

this will clear the array but the ui wont be updated.

$scope.itemarray = [];

this works fine! why?

 $scope.itemarray.length = 0;

$scope.itemarray.length = 0; << this is correct. Length is read-write property.

$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)
