Yet Another SerializeArray()

This implementation is again based on jQuery's original code, but I needed it for some Bootstrap's "switch" checkboxes with two different values.

$.fn.serializeArrayWC = function() {
    var rCRLF = /\r?\n/g;
    return this.map(function(){
        return this.elements ? jQuery.makeArray( this.elements ) : this;
    })
    .map(function(i, elem){
        if (this.type == "checkbox") {
            // Bootstrap checkboxes with two different values.
            if (jQuery(this).hasClass("switched")) {
                // Always return value (either on-value or off-value).
                return { name: this.name, value: this.value };
            }
            // Normal checkboxes. Unchecked checkboxed are not returned.
            if (!this.checked) {
                // This will be removed by the !!f filter, below.
                return false;
            }
            // Return the value, or "on".
            return { name: this.name, value: this.value||"on" };
        }
        var val = jQuery(this).val();
        if (val == null) {
            return { name: elem.name, value: null };
        } else {
            return 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" ) };
        }
    })
    .filter(function(i, f){ return !!f; })
    .get();
};
