Question

I have a form which sent the entered values using ajax:

    var form_data = {
        board_id : $("#board-tabs").tabs('option', 'selected'),
        name : $('#board_name').val(),
        csrf_test_name : $("input[name=csrf_test_name]").val()
    };

In that case form_data will be sent.

The server will return some JSON content.

Server side i’m using PHP and I’m wondering if there is some advantage sending form_data as a JSON object (considering that it must be decoded).

Answer 1

When you pass form data as a json object to jQuery ajax method it serializes into a string escaping all the required characters safe enough to transfer over http. It also depends on the type(GET/POST etc) you set in the ajax options.

The advantage is simplicity and simple to create json object instead of building a string of key/value pair.
