Include empty value fields in jQuery .serialize()

I am trying to submit a form via开发者_如何学JAVA jQuery $.post and serialize the form data via

$('form').serialize();

Unfortunately fields with unchecked radiobutton or checkboxes are not being serialized, ergo submitted.

Is there a way to include ALL fields regardless of whether they contain a value or not?

I guess this only affects fields like this

<input type="checkbox" name="some_name[]" value="1" />
<input type="checkbox" name="some_name[]" value="2" />

Make your own version of serialize :

(function( $ ){
  $.fn.mySerialize = function() {
    var returning = '';
    $('input, textarea',this).each(function(){
          var name = this.name;
          var value = this.value;
          returning += name + '=' + value + '&';
    })
    return returning;

  };
})( jQuery );


$('form').mySerialize();

You seem to be mistaken as shown in this live demo. The foo field is included even if it doesn't contain any value:

<form>
    <input type="text" name="foo" />
    <input type="text" name="bar" value="baz" />
</form>

and then:

alert($('form').serialize());

prints (as expected):

foo=&bar=baz

result: bar=

<form> 
<input name="bar" /> 
</form> 
<script> 
$(function(){ 
   $("input").click(function(){ 
       alert($("form").serialize()); 
    }); 
}); 
</script>
