How can I serializeArray for unchecked checkboxes?

Question

How can I modify this example so it can get values from checkboxes that aren\'t checked?

I want all checkboxes to have a value, if it hasn\'t been checked I want to get

Answer 1

another option is to just look at the source code for serializeArray and remove (or modify) the call to filter. I Just took that function and created a new one called serializeArrayAll like this:

$.fn.serializeArrayAll = function() {
  var rCRLF = /\r?\n/g;
  return this.map(function(){
      return this.elements ? jQuery.makeArray( this.elements ) : this;
  })
  /* this is what is excluding the unchecked checkboxes (and also other disabled options) 
      .filter(function(){
        return this.name && !this.disabled &&
            ( this.checked || rselectTextarea.test( this.nodeName ) ||
                rinput.test( this.type ) );
    })
   */
  .map(function( i, elem ){
      var val = jQuery( this ).val();

      return val == null ?
          null :
          jQuery.isArray( val ) ?
              jQuery.map( val, function( val, i ){
                  return { name: elem.name, value: val.replace( rCRLF, "\r\n" ) };
              }) :
          { name: elem.name, value: val.replace( rCRLF, "\r\n" ) };
  }).get();
};
