Remove object from array knowing its id
can you try
newArray = myArr
.filter(function(element) {
return element.id !== thisId;
});
Two solutions, one evolve creating new instance and one changes the instance of your array.
Filter:
idToRemove = DESIRED_ID;
myArr = myArr.filter(function(item) {
return item.Id != idToRemove;
});
As you can see, the filter
method returns new instance of the filtered array.
Second option is to find the index of the item and then remove it with splice
:
idToRemove = DESIRED_ID;
index = myArr.map(function(item) {
return item.Id
}).indexOf(idToRemove);
myArr.splice(index, 1);
Try like this
var id = 2;
var list = [{
Id: 1,
Name: 'a'
}, {
Id: 2,
Name: 'b'
}, {
Id: 3,
Name: 'c'
}];
var index = list.map(x => {
return x.Id;
}).indexOf(id);
list.splice(index, 1);
console.log(list);

Or you can utilize .filter()
Like this
var id = 2;
var list = [{
Id: 1,
Name: 'a'
}, {
Id: 2,
Name: 'b'
}, {
Id: 3,
Name: 'c'
}];
var lists = list.filter(x => {
return x.Id != id;
})
console.log(lists);
