[1.9 vote] Fix #12264 Customizable serializeArray result

[tedliang]

I propose to accept a callback function in the serializeArray, so that the users can customize or filter the returning object.

For example:

$('#form').serializeArray(function(val){
  return {label:this.name, value:val, type:this.type};
});

This produces the following data structure:

[{label: "a", value: "1", type: "text"},
 {label: "b", value: "2", type: "text"},
 {label: "c", value: "3", type: "hidden"},
 ....]

More powerful one:

$('#form').serializeArray(function(val){
  var $elem = $(this);
  if($elem.hasClass('invalid')){
    return null;
  }
  else if($elem.is(':date')){
    val= mySpecialDateFormat(val);
  }
  else if($elem.is(':hidden')){
    mySpecialMethodToHandleHiddenInput(this.name, val);
  }
  return {name:this.name, value:val};
});

Can you provide tests that support this feature?

Should the convertion be handled inside the default function , so one can decicde per use case if it is required?

[tedliang]

This optional converted value passed to the user is for consistency and convenience, since the rCRLF is defined inside jQuery. It's desired in most of use cases. One can retrieve the original value by calling $(this).val() explicitly.

We voted not to land this feature in core.
