将javascript表单变量传递给jQuery函数不起作用

I am trying to pass some JavaScript variables that I have assigned to form variables into a query string used by a jQuery plug in called fancybox. If I hard code in the string that I want lightbox works great, however I need it to pass some form values in there to make it work as desire.

<script type="text/javascript">
    $(document).ready(function(){

            var item = document.itemFinder.item;
            var zip = document.itemFinder.zip;
            var radius = document.itemFinder.radius;
            var dataString = "item=" + item + "&zip=" + zip + "&radius=" + radius;
            $("#various3").fancybox({
                    ajax : { type   : "POST", data  : dataString},
                    'scrolling'         : 'auto',
                    'overlayOpacity'    : '0'           
                    }               
                );
    });
    </script>

What am I doing wrong?

    The data parameter expect an object. You're passing a string. Change your call like so:

    ajax : { type: "POST", data  : {'item': item, 'zip': zip, 'radius': radius}} 
    

    That should get it to properly serialize your values for you.

    -- Updated --

    <script type="text/javascript">
      $(document).ready(function(){
         $('#someElement').change(function () {
            var item = document.itemFinder.item;
            var zip = document.itemFinder.zip;
            var radius = document.itemFinder.radius;
            var dataString = "item=" + item + "&zip=" + zip + "&radius=" + radius;
            $("#various3").fancybox({
                    ajax : { type   : "POST", data  : dataString},
                    'scrolling'         : 'auto',
                    'overlayOpacity'    : '0'           
                    }               
                );
      });
    });
    </script>
    

    In my example I'm not sure which event you actually want to bind to (your call), and I'm not sure what other elements are available, but hopefully that makes sense anyway. Thanks,
