I'm taking over an app that uses a bunch of client side Java. The only reason I can see it uses Java is because it allows you to build logic like "if this radio button is selected, this checkbox is disabled." If there was a way to do this in a combination of DTML and Javascript then the app could use just those technologies. Has anyone got a demo of something like that? I can think of fairly convoluted ways to do it -- is there a straightforward way?
This is actually quite straightforward in the HTML 4.0 spec. Section 17 discusses forms. 17.12.1 Disabled controls: The following elements support the disabled attribute: BUTTON INPUT, OPTGROUP, OPTION, SELECT, and TEXTAREA. eg: <INPUT disabled name="fred" value="stone"> Note: the only way to dynamically modify the value of the disabled attribute is through a script. ... I don't know the exact javascript to do this, but it should be pretty straightforward. I imagine you can do this server-side with dtml, but with javascript it would be all client-side. -- mindlace Disclaimer: Any use of this email, in any manner whatsoever, will increase the amount of disorder in the universe.
