Use a Jump Menu to Make Selection and stay on same page.

Question

I have a form that you select a ID from a drop down list
click submit, and then are redirected back to the same page with
the results of a query based on the selection from the drop down
list. I want to change this so the user doesn't have to click
submit... I want my drop down list to act as a jump menu. How do I
get my dropdown list to act like a jump menu, which essentially
submits the form, and posts the results below?

Answer 1

2 ways, both use javascript (you can't do it with just cf):
1) add an onChange attribute to your select with
'this.form.submit()' as
value. this will submit the form, refresh the page and show
your results
- just as if user clicked your 'submit' button. be careful,
though, if
you are checking for existence of the submit button in your
action page
- it won;t be there since it has not been clicked.
2) you can also employ some ajax features to submit your form
asynchronously, 'behind the scenes', and show results without
refreshing
the page. CF8 has built-in ajax js functions and tags to do
it,
otherwise look into ajaxcfc by rob gonda or jQuery or other
js framework
that has these features.
