Set up a text entry box to not accept a null value

[mannguy]

Hi

I'm using Captivate 2019, I want to set a text entry box to force a user to enter their name and if they omit this, then a message box to display stating that their name must be entered before they can continue. I have set up my text entry box and trxt caption box to display the message but I've been unable to get this to work.

I have seen a guide to how to do this but I think it is old and some of the advanced actions look different in my version. I did manage some of it in adding an advanced action of creating if v_name is equal to v_null and Show NameIncorrect. The guide then goes to adding an expression and this is where I get stuck. The example shows rdcmdGoToFrame = rdinfoCurrentFrame - 1. I can't see rdcmdGoToFrame or rdinfoCurrentFrame in the drop down lists. Can anyone advise me please?

Thanks in advance

Guy

Thank you Stagprime, I'll take a look and see if I can learn a bit about JavaCode. The reason I'm still publishing to SWF is that I upload files to an intranet which is quie old and doesn't have compatibilty with HTML5. Moving over to a new system shortly so I'll then publish in HTML5.

If you're interested in another approach to this - I offer a JavaScript option.

1. Make a text entry box and delete the submit button that comes with it.

2. Make a variable (in my example - I call it  yourName)

3. Make sure that the text entry box is associated with the variable that you create.

4. Make your own smart shape to act as a button by clicking the 'Use as Button' check box

5. For the button onSuccess action - choose 'Execute JavaScript'

6. Place the following code in the Script_Window

7. In this example I have a box named 'error' that is hidden by default and have it show if the field is left blank.

if (yourName=="") {
cp.show("error");
}

else {
cp.goToNextSlide();
}

In my example - you would just need to replace the  yourName  variable with your own.

If you have any questions about this I would be happy to elaborate.

Thank you Stagprime, I've never attempted anything with Javascript but I 'll give your suggestion a go and let you know how I get on. Thanks again.

If you copy this - it may fail until you go back and delete the quotation marks and actually type them with the keyboard.

The blog post clearly has a conditional action with ELSE included. 

This must be very confusing for a newbie,  because in this thread two proposed solutions are now mixed up.

I understood that you wanted to use tje JS solution... My approach is different, as a diehard teacher I prefer to teach how to fish, in stead of offering a fish (copy/paste code without realy understanding it). It is up to you which approach you prefer, but both will need time...

I am personally VERY grateful for Stagprime offering his JavaScript solutions when able.  

I like fish and chips.  Personally, I don't care HOW the fish was caught as long as it tastes good in batter.

Thanks Rod,

As I stated above - I also prefer that people learn and understand but how else do we motivate learning if not by exposing the learner to that which is possible?

As they say -  "You don't know what you don't know."

"I like fish and chips.  Personally, I don't care HOW the fish was caught as long as it tastes good in batter". That's funny lol.  Whilst I do just need a solution and I don't really mind which way I get there, I do really appreciate all of the advice and solutions to my issue that both Stagprime and Liliybiri have offered.
