JAVASCRIPT: how can I remove a json object in json object?

how can I remove a json object in json object?

[
    [
        {"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"}
   ]
]

I save this json in ordering

Now I want remove 

   [   {"name":"extera_Ordering_json[count]","value":"1"},
       {"name":"coupon","value":"1"},
       {"name":"formtype","value":"ordering"},
       {"name":"extera_Ordering_json[id]","value":"4"}
   ]

My key is extera_Ordering_json[id] (it is not unique)

I do this:

ordering = JSON.parse(ordering);
var temp;
$.each(ordering, function(idx, obj)
{
    if(obj.Ordering_json[id] != 4)// not works
    {
        temp[] = obj;
    }
    temp[] = obj
}
ordering = JSON.stringify(temp);

you can use splice method 

ordering = [ /*Array without json parsing*/ ];
var indexToDelete = 3;
ordering.splice( indexToDelete, 1); 
// 1 indicates only one element from array 
console.log(ordering);

You are using id instead of idx. try this

if(obj.Ordering_json[idx] != 4)

This should do what you want:

var ordering = [
    [
        {"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 sVal = 4;
    var indexToRemove = false;
    ordering.forEach(function(element, index) {
       element.forEach(function(subelement) {
           if (subelement.name == "extera_Ordering_json[id]" 
              && parseInt(subelement.value) == sVal){
              indexToRemove = index;
           }
       });
    });

    if (false !== indexToRemove) {
        ordering.splice(indexToRemove, 1);
    }

in your case extera_Ordering_json[id] is not key, it is value of name

    var ordering = [
        [
            {"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 temp = [];
    $.each(ordering, function (key1, obj1) {
        $.each(obj1, function (key2, obj2) {
            if (obj2.name == 'extera_Ordering_json[id]' && obj2.value == 4) {
                delete ordering[key1];
            }
        });
        if(ordering[key1] != null){
            temp.push(ordering[key1]);
        }
    });
    console.log(JSON.stringify(temp));

"extera_Ordering_json[id]" is simply a string so you need to iterate all the objects in each array and find the one that has that string as name and check the value of the same object

Here's a map and filter approach

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 = 1
data=data.map(function(arr){
   return arr.filter(function(o){
      return o.name !== "extera_Ordering_json[id]" || +o.value !== searchVal
   })
})

console.log(data)

You could use the splice method on your JSON array to remove an element at a specific index:

var ordering = JSON.stringify([
    [
        {"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"}
   ]
])

temp = JSON.parse(ordering);
temp.splice(3, 1)
ordering = JSON.stringify(temp);
console.log(ordering)
