I'm trying to build a form whose "submit" button only becomes enabled after text is present in a specific field (and likewise when that field is blank, the "submit" button returns to disabled status). Does anyone know of a painless way to do this? I'd also like the user to be able to hit return from within that field and have the "submit" button entered. Right now, it seems, the return key must be hit twice in order to first exit the field and then select "submit".
I like to use a "send in time" message that checks all the relevant fields and enables or disables buttons accordingly. I prefer it to closeField as it happens in real time, instead of waiting for the user to get out of the field. For example: -- start the messsage going on openCard send "checkButtons" to me end openCard -- check all the things you need & set the button -- you can make this check as complex as you like on checkButtons if fld "Essential" is empty or fld "Number" is not a number then disable btn "Submit" else enable btn "Submit" end if -- send the message again if the pendingMessages contains "checkButtons" is false then send "checkButtons" to me in 10 ticks end if end checkButtons -- stop the message when closing the card on closeCard put the pendingMessages into tList repeat for each line L in tList if item 3 of L contains "checkButtons" then cancel item 1 of L end repeat end closeCard Then for the Return key being able to hit the button: on returnInField click at the loc of btn "Submit" end returnInField I like this method as it won't do anything if the button is disabled, and if it does work, it gives visual feedback of the buttoon being clicked. Don't forget that you can also use enterInField and if the autoTab is set to true, you might like to use the tabKey message.
