Title: Javascript to update another field on a form
Post by: Mike Grigsby on November 01, 2007, 01:38:48 PM

Anyone have advice or examples of how to do the following?

I have a two fields that will be combined to prefill another field's value. I was thinking of using javascript for this, but I'm not even sure how to approach this with the Form template.

The fields are:
AST:YearOfManufacture
AST:Make

and they would be combined to form the dynamic value that goes into the next field:

AST:Description

Also, does the javascript handcode ellipse/lookup button on the field act like an include (I guess I could test this).

Thanks for any suggestions. MikeG

Hi Mike,

no, I wouldn't use javascript to do this. The templates pretty much let you do this without resorting to non-clarion code.

For both the YearOfManufacture, and Make fields,do the following;

on the "client side" tab,
a) tick on "send new value to server".
b)  add AST:Description to the "Reset" Field list
c) click on the "server code" button.
d) find the right field (Year or Make) and add the following code;

AST:Description = AST:YearOfManufacturer & ' ' & AST:Make
p_web.SetSessionValue('AST:Description',AST:Description)

Now, on the form, if either the Make or Manufacturer field changes, then the Description field will change as well.

Cheers
