My javascript code like this :
<script type="text/javascript">
var clubs = [
{id: 1, name : 'chelsea'},
{id: 2, name : 'city'},
{id: 3, name : 'liverpool'}
];
if(clubs.indexOf(2) != -1)
clubs.splice(2, 1)
console.log(clubs)
</script>
For example, I want to delete the index with id = 2
I try like that, but it does not work. The index with id = 2 is not deleted
How can I solve this problem?
Here is a way to solve your problem, check this :
var clubs = [
{ id: 1, name: 'chelsea' },
{ id: 2, name: 'city' },
{ id: 3, name: 'liverpool' }
];
for (var i = 0; i < clubs.length; i++) {
if (clubs[i].id == 2) {
clubs.splice(i, 1);
break;
}
}
console.log(clubs);
Use Array.filter
var clubs = [
{id: 1, name : 'chelsea'},
{id: 2, name : 'city'},
{id: 3, name : 'liverpool'}
];
clubs = clubs.filter(function(item){
return item.id !== 2;
});
console.log(clubs);
The element is not getting deleted because of your if statement, you are checking if 2 is present or not in array, but there is nothing like 2 in array as it is an array of objects. So the condition always remains false.
