Question

I have read quite a few different methods of having html checkboxes get posted to the server, but I am really looking to do it without modifying anything except for $.serialize. I ideally, I would like checked boxes to be posted as on, and unchecked to be posted as 0, empty, or null.

I’m a little confused by jquery’s inner-workings, but I’ve got this so far, but it sets unchecked checkboxes to ‘on’… Can anyone tell me how to continue this modification below?

$.fn.extend({
    serializeArray: function() {
        return this.map(function(){
            return this.elements ? jQuery.makeArray( this.elements ) : this;
        })
        .filter(function(){
            return this.name && !this.disabled &&
                ( this.checked || !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( /\r?\n/g, "\r\n" ) };
                    }) :
                    { name: elem.name, value: val.replace( /\r?\n/g, "\r\n" ) };
        }).get();
    }
});

It’s a minor change:

    .map(function( i, elem ){
        var val = jQuery( this ).val();
        if ((jQuery(this).checked != undefined) && (!jQuery(this).checked)) {
            val = "false";
        }

I haven’t tested but it seems the most logical approach. Good luck
