How to convert form data to JavaScript object with jQuery

Question

How do I convert all elements of my form to a JavaScript object?

I'd like to have some way of automatically building a JavaScript object from my form, without having to loop over each element. I do not want a string, as returned by $('#formid').serialize();, nor do I want the map returned by $('#formid').serializeArray();

Hello @kartik,

You can use:

function form_to_json (selector) {
  var ary = $(selector).serializeArray();
  var obj = {};
  for (var a = 0; a < ary.length; a++) obj[ary[a].name] = ary[a].value;
  return obj;
}

Output:

{"myfield": "myfield value", "passwordfield": "mypasswordvalue"}

Thank You!!
