How to remove items from an array of objects?

Question

How to remove items from an array of objects? There is an array of properties per which it is necessary to remove items from which isn isn coincides with the array. Here is an example:

let selectedIsn = [10,15,20,30,40];
let arayObject = [{
  isn:10,
  name:"Bolt"
}, {
  isn:13,
  name:"marry"
},{
  isn:15,
  name:"a"
},{
  isn:18,
  name:"q"
}, {
  isn:20,
  name:"marrys"
},{
  isn:25,
  name:"aa"
},{
  isn:30,
  name:"qa"
}, {
  isn:40,
  name:"marrya"
},{
  isn:55,
  name:"sa"
},{
  isn:68,
  name:"qas"
 }];

let deleteSelected = (q,selectedItems) => {
        let arrayNew = q,
            count=0;

    for (var m = 0; m < q.length; m++) {
        let index = selectedItems.indexOf(q[m]["isn"]);
        if (index > -1) {
            arrayNew.splice(m - count, 1);
            count++;
        }
    }
    return arrayNew;
}

deleteSelected(arayObject,selectedIsn);

Removes not all elements of the given list. I do not understand what's wrong doing.

Answer 1

You can use .filter function to get selected items from array

let deselected = arayObject.filter(function (a) {
   return selectedIsn.indexOf(a.isn) < 0;
});

Answer 2

像这样使用过滤器

var result = arayObject.filter(item => selectedIsn.indexOf(item.isn)===-1);
