Here i m given some data in Json formate. I want to fillter it with it atrribute .

[
{
    "_id": "1",
    "name": "ShalimarBhagh",
    "city_id": "1",
    "location_id": "1",
    "country_name": "India"
},
{
    "_id": "2",
    "name": "Janpat, Delhi",
    "city_id": "1",
    "location_id": "2",
    "country_name": "India"
},
{
    "_id": "3",
    "name": "MSP, Delhi",
    "city_id": "1",
    "location_id": "3",
    "country_name": "India"
},
{
    "_id": "4",

    "name": "Janpat, Delhi",

    "location_id": "2",
    "country_name": "India"
},
{
    "_id": "3",

Just use array's filter method:

const data = [
  {
    _id: "1",
    name: "ShalimarBhagh",
    city_id: "1",
    location_id: "1",
    country_name: "India",
  },
  {
    _id: "2",
    name: "Janpat, Delhi",
    city_id: "1",
    location_id: "2",
    country_name: "India",
  },
  {
    _id: "3",
    name: "MSP, Delhi",
    city_id: "1",
    location_id: "3",
    country_name: "India",
  },
];

const filtered = data.filter((item) =>
  item.name.toLowerCase().includes("delhi")
);

console.log(filtered);

Let's say your array is stored in a variable called elements.

What you can do is filter all of the elements with a condition that the name includes string "Delhi"

const elements = [
{
    "_id": "1",
    "name": "ShalimarBhagh",
    "city_id": "1",
    "location_id": "1",
    "country_name": "India"
},
{
    "_id": "2",
    "name": "Janpat, Delhi",
    "city_id": "1",
    "location_id": "2",
    "country_name": "India"
},
{
    "_id": "3",
    "name": "MSP, Delhi",
    "city_id": "1",
    "location_id": "3",
    "country_name": "India"
},
{
    "_id": "4",
    "name": "MSP, Pune",
    "city_id": "2",
    "location_id": "4",
    "country_name": "India"
},
{
    "_id": "5",
    "name": "Anand Pur",
    "city_id": "1",
    "location_id": "5",
    "country_name": "India"
}];

const result = elements.filter(element => element.name.includes("Delhi"));

console.log(result);

Now result contains all elements whose name includes Delhi. Note that this does not modify the original array, instead it returns a new array.

You can use the .filter() function. If the array is named arr then:

var new_array = arr.filter(function callback(element, index, array) {
    return (element.name.includes("Delhi"))
});

Where new_array is the filtered array.
