How to use filter in angularjs

Question

I have the following data

var data = [
    {
        "h_id": "31",
        "city": "hill",
    },
    {
        "h_id": "13",
        "city": "Bevery Hills",
    },
    {
        "h_id": "5",
        "city": "New York",
    },
    {
        "h_id": "31",
        "city": "New York",
    },
    {
        "h_id": "5",
        "city": "New York",
    }
];

I am getting data in this format

var data1 = [
    {
        "h_id": "31",
        "city": "hill",
    }, {
        "h_id": "13",
        "city": "Bevery Hills",
    }, {
        "h_id": "31",
        "city": "New York",
    }
];

I want data in this format

var data1 = [
    {
        "h_id": "31",
        "city": "hill",
    }, {
        "h_id": "31",
        "city": "Bevery Hills",
    }
];

This is my angularjs script

$scope.data1 = $filter('filter')($scope.data , {h_id:31} )

I want the data to be filter based on exact match.filter concept i used above not filtering based on exact match.

This page documents how to create your own angular filter scotch.io/tutorials/building-custom-angularjs-filters If its a filter for checking h_id of an object you could create a h_id filter and pass it your Array of objects as the first param and the ID as the second param and then in your $filter use YOUR_ARRAY.filter(item => item.hi_id === ID PARAM) — Francis Leigh

Use Array.filter() to get results matching certain condition.

var data = [{
  "h_id": "31",
  "city": "hill",
}, {
  "h_id": "13",
  "city": "Bevery Hills",
}, {
  "h_id": "5",
  "city": "New York",
}, {
  "h_id": "31",
  "city": "New York",
}, {
  "h_id": "5",
  "city": "New York",
}];

var newData = data.filter(el => el.h_id==="31");
console.log(newData);

Use the third parameter to strict comparison:

$scope.data1 = $filter('filter')($scope.data , {h_id:31}, true )

Here you have the documentation
