angularjs 删除数组的值

全局变量定义：

/**
 *删除数组指定下标或指定对象
 */
Array.prototype.remove=function(obj){
    for(var i =0;i <this.length;i++){
        var temp = this[i];
        if(!isNaN(obj)){
            temp=i;
        }
        if(temp == obj){
            for(var j = i;j <this.length;j++){
                this[j]=this[j+1];
            }
            this.length = this.length-1;
        }
    }
}

删除方法：

$scope.removeByValue = function(arr, val) {
    for(var i=0; i<arr.length; i++) {
        if(arr[i] === val) {
            arr.splice(i, 1);
            break;
        }
    }
};
$scope.unSuspectAll = function(data) {
    var item =  data.suspectList;
    for(var i=0;i<item.length;i++){
  
$scope.removeByValue($scope.SuspectFrom.ids1,item[i].suspectId);
    }
};
