How to pass Json array to servlet

Question

[DUPICATE]

~~This My POST JSON Code~~

var data_create = JSON.stringify($("#form_create_delegate").serializeArray());

        alert("isi data_create" + data_create);

//        console.log(data_create)
        $.ajax({
            type: "POST",
            url: "formCreateDelegationServlet",
            dataType: "json",
            data:data:{JSONFile:data_create},
            success: function (response) {  }


        });

THIS MY Result JSON

JSONFile:[{"name":"id_form_delegate","value":"1"},{"name":"merchant","value":"AMBHARA HOTEL TERBAIK"},{"name":"citty","value":"JAKARTA PUSAT"},{"name":"addrs","value":"JL. DIPONEGORO NO.  1J"},{"name":"province_merchant","value":"DKI JAKARTA"},{"name":"mid_merchant[]","value":"1"},{"name":"tid_merchant[]","value":"1"},{"name":"mid_merchant[]","value":"2"},{"name":"tid_merchant[]","value":"2"}]

How to remove property "name" and "value" from my JsonArray

I want to make a format like this

[{"merchant":"AMBHARA HOTEL TERBAIK","citty":"JAKARTA PUSAT"}]

this my servlet code

JSONArray jsonArray = (JSONArray) net.sf.json.JSONSerializer.toJSON(request.getParameter("JSONFile"));

            merchant = jsonObject.getString("merchant");
            city = jsonObject.getString("city");
            addrs = jsonObject.getString("addrs");
            province_merchant = jsonObject.getString("province_merchant");
            tid = jsonObject.getString("tid_merchant");
            mid = jsonObject.getString("tid_merchant");
//            
            System.out.println("nama_merchant: " + nama_merchant);
            System.out.println("kota_merchant: " + kota_merchant);
            System.out.println("alamat_merchant: " + alamat_merchant);
            System.out.println("province_merchant: " + province_merchant);
            System.out.println("mid: " + mid);
            System.out.println("tid: " + tid);

But it doesn't work

What do you mean by remove? Nothing will be left if you get rid of those properties from your object — Mr. Alien, Jan 09 '17 at 10:46
You question is not clear. Maybe you want an array of arrays like this `[["id_form_delegate","1"],["merchant",""AMBHARA HOTEL TERBAIK"]]` ... ? — edc65, Jan 09 '17 at 10:50

If you want to get rid of keys and just keep values as arrays, you can use Array.map like this

var input=[{"name":"id_form_delegate","value":"1"},{"name":"merchant","value":"AMBHARA HOTEL TERBAIK"},{"name":"citty","value":"JAKARTA PUSAT"},{"name":"addrs","value":"JL. DIPONEGORO NO.  1J"},{"name":"province_merchant","value":"DKI JAKARTA"},{"name":"mid_merchant[]","value":"1"},{"name":"tid_merchant[]","value":"1"},{"name":"mid_merchant[]","value":"2"},{"name":"tid_merchant[]","value":"2"}]

var result = input.map(function (obj) {return [obj.name, obj.value]})

console.log(JSON.stringify(result))

You can make it dynamic, so that it just works with any property and not only "name" and "value", using Object.keys (not supported in MSIE pre 9). But beware that you lose control on the order of values in output.

input=[{"name":"id_form_delegate","value":"1"},{"name":"merchant","value":"AMBHARA HOTEL TERBAIK"},{"name":"citty","value":"JAKARTA PUSAT"},{"name":"addrs","value":"JL. DIPONEGORO NO.  1J"},{"name":"province_merchant","value":"DKI JAKARTA"},{"name":"mid_merchant[]","value":"1"},{"name":"tid_merchant[]","value":"1"},{"name":"mid_merchant[]","value":"2"},{"name":"tid_merchant[]","value":"2"}]

result = input.map(function (obj) {
  return Object.keys(obj).map(function (key) {return obj[key]})
})

console.log(JSON.stringify(result))

@AdamAzad it's not what OP is asking, but it's an interesting task — edc65, Jan 09 '17 at 10:57
