How to Remove a Json Inside a Json by a Key Using Jquery

var data = [    [        {"name":"formtype","value":"ordering"},                  {"name":"extera_Ordering_json[id]","value":"1"}   ],   [        {"name":"extera_Ordering_json[count]","value":"20"},                       {"name":"coupon","value":""},        {"name":"formtype","value":"ordering"},         {"name":"extera_Ordering_json[id]","value":"2"}   ],   [       {"name":"extera_Ordering_json[count]","value":"7"},       {"name":"coupon","value":"1"},       {"name":"formtype","value":"ordering"},       {"name":"extera_Ordering_json[id]","value":"3"}   ],   [   {"name":"extera_Ordering_json[count]","value":"1"},       {"name":"coupon","value":"1"},       {"name":"formtype","value":"ordering"},       {"name":"extera_Ordering_json[id]","value":"4"}   ]]var searchVal = 1data=data.map(function(arr){   return arr.filter(function(o){      return o.name !== "extera_Ordering_json[id]" || +o.value !== searchVal   })})
console.log(data)

Remove JSON element

var json = { ... };
var key = "foo";
delete json[key]; // Removes json.foo from the dictionary.

You can use splice to remove elements from an array.

How to remove JSON object/Token from JSON with changing keys

Try this if it can help you,

var json = File.ReadAllText("json1.json");
var myJobj = JObject.Parse(json);
var rk3 = myJobj.SelectToken("rootkey3");

foreach (var ck in rk3.Children())
{
     var ck1 = ck.SelectToken("$..childkey1").ToString();
}

Nested JSON, remove object based on a condition in Jquery using angularjs

You can use _without() function of _underscorejs

see the documentation

without

_.without(array, values)

Returns a copy of the array with all instances of the values removed.

_.without([1, 2, 1, 0, 3, 1, 4], 0, 1);

=> [2, 3, 4]

Input

[
    {
        "market": "Atl",
        "subItem": [
            {
                "comment_id": "1",
                "user_id": "32509",
                "flag": true
            },
            {
                "comment_id": "2",
                "user_id": "32510",
                "flag": false
            }
        ]
    },
    {
        "market": "Chicago",
        "subItem": [
            {
                "comment_id": "3",
                "user_id": "32501",
                "flag": true
            },
            {
                "comment_id": "4",
                "user_id": "32502",
                "flag": false
            }
        ]
    }
]

Output

[
    {
        "market": "Atl",
        "subItem": [
            {
                "comment_id": "1",
                "user_id": "32509",
                "flag": true
            }
        ]
    },
    {
