I use vue.js and I want to delete elements of an array that have specific id
value.
For example :
I want to delete elements that have id
of 0. I tried to use the findindex
and then delete the element but I couldn't implement that, and to use the splice
method you have to know the index before deleting.
"Options": [
{
"id": 0,
"option": "A",
"value": "2"
},
{
"id": 0,
"option": "B",
"value": "1"
},
{
"id": 0,
"option": "C",
"value": "3"
},
{
"id": 1,
"option": "A",
"value": "1"
}
One more ( polyfill ):
var array = [{id:1},{id:0},{id:0},{id:2}]; array = array.filter(x => x.id != 0); console.log(array);
x => x.id != 0
is the same as function (x) { return x.id != 0; }
function (x) { return x.id != 0; }
.
for + splice (there are plenty of solutions with the same result):
var array = [{id:1},{id:0},{id:0},{id:2}]; removeIf(array, x => x.id == 0); console.log(array); function removeIf (array, predicate) { var i, n = array.length; for (i = 0; i < n; i++) { if (predicate(array[i])) { array.splice((n--, i--), 1); } } }
