javascript - angular splice overwriting element on move fromIndex, toIndex -

i have array exposed $scope called exercises containing array of exercises objects this:

[    {      "exercisename": "half lunge ",      "exercisedescription": "stand 1 foot forward taking of weight.",      "images": [71,73]    } ]

i aim move exercise 1 position using following:

$scope.moveitem = function(exercise, fromindex, toindex) {  $scope.exercises.splice(fromindex, 1);  $scope.exercises.splice(toindex, 0, exercise); };

however overwriting exercise in toindex data fromindex

you passing 1 perameter in function. remove exercises perameter element.

<ion-reorder-button class="ion-navicon" on-reorder="moveitem(exercise, $fromindex, $toindex)"></ion-reorder-button>
