I've got an array of JSON data structured like this:
[
{
id: 1,
name: 'Alice'
},
{
id: 2,
name: 'Bob'
},
{
id: 3,
name: 'Eve'
}
]
My goal is to locate an object by its id and append a deleted: true property to it.
I'm curious about the most straightforward method to achieve this.
If you're looking to update an object within an array, you can utilize the following versatile function by providing the array and the id of the object as parameters.
var arr = [
{
id: 1,
name: 'Alice'
},
{
id: 2,
name: 'Bob'
},
{
id: 3,
name: 'Charlie'
}
];
function modifyObject(data, id){
data.forEach(obj => {
if(obj.id === id){
obj['updated'] = true;
}
});
return data;
}
let id = 2;
console.log(modifyObject(arr, id));If you need to find a specific user in an array, using Array.prototype.find is the most straightforward approach.
let employees = [
{
id: 1,
name: 'Alice'
},
{
id: 2,
name: 'Bob'
},
{
id: 3,
name: 'Carol'
}
];
let id = 2;
let foundEmployee = employees.find(employee => employee.id === id);
console.log('Employees before update', employees);
foundEmployee.status = 'Inactive';
console.log('Employees after update', employees);Give this a try:
var array = [
{
id: 1,
name: 'John'
},
{
id: 2,
name: 'Jack'
},
{
id: 3,
name: 'Peter'
}
]
for (var item in array){
if (array[item].id === 1){
array[item].deleted = true;
break;
}
}
console.log(array)This code snippet iterates through each element in the array and checks if the specified value is present. If it finds a match, it adds a boolean attribute named deleted to that element and then exits the loop.
