jQuery.fn.getCheckboxVal = function(){ 
    var vals = []; 
    var i = 0; 
    this.each(function(){ 
        vals[i++] = jQuery(this).val(); 
    }); 
    return vals; 
}


// EXAMPLE
var arr = $("input[name='fieldname']:checked").getCheckboxVal() 
//would return an array like: 
// ['val1', 'val2', 'val3']
