To create the custom form, I used Google Docs to create a Google-hosted form. Then I simply looked at the generated form, lifted the relevant HTML, and pasted it into my own CMS (MyST Blogsite, in this case, but any HTML web page would do.) I basically rewrote the generated HTML to simplify it, style it the way I wanted, and to add some simple JavaScript form validation logic as you might in any web form. The key was starting with the Google-generated form so I had the appropriate field names and action address. To see the detail, feel free to view the source of this page:
http://myst-technology.com/public/enterprise-rss/setup (Search the source for "SETUP_FORM" to find the custom form.) There is a little HTML/JavaScript trickery that may not at first be obvious. This is not absolutely necessary, but I added it to provide a little smoother user experience. First, there is a hidden DIV element that contains a thank you message. The JavaScript shows this DIV after the form is submitted. Search for "ID_Response" to find this DIV. Second, there is an empty IFRAME (search for "id_result") that is used to hold the response from the form submission. This is accomplished using target="id_result" on the custom FORM element. And, since we present our own "thank you" message for form submission, we really don't need to see Google's response, so I set the height of the result IFRAME to 1. |
