I have an array like below
const arr = [
{
id: "first",
val: 'ganguly',
},
{
id: "third",
val: 'sachin',
},
]
const selectedVaue ='dhoni';
if id is match to 'third' then value to replace to particular key
const list = arr.filter(data => data.id === 'third');
if (list.length > 0 ) {
// code
}
Expected result lie below :
const arr = [
{
id: "first",
val: 'ganguly',
},
{
id: "third",
val: 'dhoni',
},
]
You can use Array.prototype.map and create a new array with the value with id "third" replaced.
const arr = [
{ id: "first", val: "ganguly" },
{ id: "third", val: "sachin" },
];
const selectedValue = "dhoni";
const res = arr.map((a) =>
a.id === "third" ? { ...a, val: selectedValue } : a
);
console.log(res);Or you can use Array.prototype.forEach if you want to replace the object in place.
const arr = [
{ id: "first", val: "ganguly" },
{ id: "third", val: "sachin" },
];
const selectedValue = "dhoni";
arr.forEach((a, i) => {
if (a.id === "third") {
arr[i] = { ...a, val: selectedValue };
}
});
console.log(arr);
