form question

rtown

just curious as to how stupid this sounds...I have been looking for quite some time to find some code to help me with dynamically loaded dropdown boxes, in javascript, now there have been mixed feelings on it due to the fact of being able to turn off js and also that Netscape doesn't support all the features in some occurences. this may be a simple "no" question, but could I instead have a button that would submit the form once a size is selected, since that is the criteria that I need to determine the price, and then reload the page with the selected size and its corresponding price...but then have a submit button for the entire form since it is to be part of a shopping cart. so essentially 2 buttons on 1 form or something similar???

brain is fried and out come the stupid ideas....smokem if ya gottem!

Simple "Yes" answer.

You can submit a form any number of times and it's up to the php script called what happens next.

Primarily you'll process the data sent and see whether there is a value for the actual "submit" button. If not then the submit must be triggered by a change event.

I have an awesome links page at http://property.digitalrice.com/links.html and the best javascript reference I have found to date is Dev Guru's Reference Page which explains all the methods etc.

You're on the right track, just keep at it.

thanks for the reply, good to see that I do have "educated" guesses down to an art😉 What did you mean by

If not then the submit must be triggered by a change event.

Are we talking about an onChange event, or something diff?

I'll check out those links, I've never had a bad link sent to me through this forum, so I am sure they'll be ery helpful.

Thanks again, may be in touch...

I was looking at my form and if I have to buttons, wouldn't it cause a problem if one was to post to itself to reload the page with the satisfied query and new data, and the other button would be the one that would submit the page and all it's data to another page...I am creating a shopping cart, and once the product is selected then it will go to a view cart page and display the data...would this make me require 2 forms😕 😕

alot of this comes down to design and flow.

Yes, you are using the onchange event so that you dont' need buttons- or to rely on the user clicking them.

You can have a single script handling a form in all it's "states" and finally, when the user has pressed submit managing that.

Or...

the form with the final submit button has no visible controls, just a stack of hidden fields with the values from the last time the form was submitted. If anything changes the other submit will happen and the final form will be updated.

If you design your page well your user won't know the difference.
