I have an array of json objects, for eg
var user =[ { id: 1, name: 'linto', img: 'img' },
{ id: 2, name: 'shinto', img: 'img' },
{ id: 3, name: 'hany', img: 'img' } ]
From this, i need to remove a particular json object
{ id: 2, name: 'shinto', img: 'img' }.
ie the output array should be like this
[ { id: 1, name: 'linto', img: 'img' },
{ id: 3, name: 'hany', img: 'img' } ]
Is there any function in node.js to achieve this ?
use delete command for that.
E.g.
delete user[index]
EDIT: splice command works better in case of array as it fully removes the element. In case of delete null replaces the deleted element.
user.splice(0,<index>);
Full code :
var user =[ { id: 1, name: 'linto', img: 'img' },
{ id: 2, name: 'shinto', img: 'img' },
{ id: 3, name: 'hany', img: 'img' } ]
alert(JSON.stringify(user));
user.splice(0,1);
alert(JSON.stringify(user));
There is an underscore way for the same.
var user = [{
id: 1,
name: 'linto',
img: 'img'
}, {
id: 2,
name: 'shinto',
img: 'img'
}, {
id: 3,
name: 'hany',
img: 'img'
}]
console.log(_.reject(user, function(usr) {
return usr.name == 'shinto';
}));<script src="http://underscorejs.org/underscore.js"></script>
