View Full Version : $(document).ready(function() or $(function()

08-20-2011, 07:35 PM
Hello all. I have fairly simple questions regarding modifying this script: http://papermashup.com/create-a-dynamic-form-preview/ to dynamically show different parts of a form on another part of the page. I am looking to use it on most parts of my form and would like a little clarification.

First is the use of $(document).ready(function() or $(function(). It works using either, my question is which is preferred? As I understand it using $(document).ready(function() starts the DOM immediately on page load and is useful if you need something right away. I am also using this script: http://www.dynamicdrive.com/dynamicindex16/formwizard.htm for the form. Since the preview script is being used with the form to wizard, I don't really need it until the rest of the form loads.

Another question would be, is there a cleaner way to go about using the preview script on say 10 different form inputs independently? For example in a single function rather than 10 different function/updates?

I have an example of what I am trying here: http://jsfiddle.net/anhyG/1/

Thank you in advance for any help!
