jQuery serializeArray() key value pairs

Question

I\'m having a bit of trouble serializing a form

Answer 1

Here is some modernization of Hollister's code.

(function($,undefined){
  '$:nomunge'; // Used by YUI compressor.

  $.fn.serializeObject = function(){
    var obj = {},
        names = {};

    $.each( this.serializeArray(), function(i,o){
      var n = o.name,
        v = o.value;

        if ( n.includes( '[]' ) ) {
          names.n = !names.n ? 1 : names.n+1;
          var indx = names.n - 1;
          n = n.replace( '[]', '[' + indx + ']' );
        }

        obj[n] = obj[n] === undefined ? v
          : $.isArray( obj[n] ) ? obj[n].concat( v )
          : [ obj[n], v ];
    });

    return obj;
  };

})(jQuery);

In case you need field names as myvar[] for checkboxes.
