I forgot to mention that Ray Camden has a good blog post about filling in form field values with jQuery and Ajax:
http://www.coldfusionjedi.com/index.cfm/2010/5/24/Example-of-jQuery-loading-form-fields hth, larry > With jquery, no you can call a .cfm page. You just have to make sure > the data is in the proper format. Here's an example where what's > returned is just plain html: > > <s/cript> > $('.subMenuItem').live('click', function() { > var thelink = $(this); > var theURL = thelink.attr('href'); > $("#contentDiv").load(theURL); > return false; > }); > > </s/cript> > > Basically what happens here is that you're telling jQuery that > whenever a user clicks on something with a subMenuItem class, you want > to extract the value of the href attribute. Then do an ajax call to > the href value (in this case vendors.cfm but it could also have been > to a cfc). The final step inserts the returned information into the > html of the contentDiv. > > In my vendors.cfm template there is a simple query and some html > layout (basically a list of links), but it could have also been json > data, xml or javascript.
