Question

Captivate 8 and Javascript Play common interface function

  • October 19, 2016

I have a weird issue.  I have a slide that prompts for input with a submit button.

The button calls a very simple javascript that checks if the field is blank.  If it is it puts up an alert box explaining the issue and pauses the movie, so the user has a chance to put something in the box before it continues playing.  If it isn't blank it stores the data in a variable and should then continue the movie.

window.cpAPIInterface.pause(); works fine

window.cpAPIInterface.play(); doesn't do anything.

So now the movie pauses at the slide and I can't seem to get it moving again.  If I use

windows.cpAPIInterface.next(); it will skip to the next slide as expected but it stays paused.

I thought maybe it was my scripting since i'm no javascript expert so i created another button and the only line of script is the common interface play command and it also does nothing when pressed.

For reference my goal is using HTML5 output.

For testing I also previewed in standard flash output in which case the play button works, but the none of the functions from the original box and button work.  I'm sure I could accomplish this without javascript but my project requires several instances of similar functions and it will make it a lot easier if I can just call the function each time.  Haven't used Captivate for a few versions so wasn't sure if there was some large javascript changes.

    I have used some of those commands with success. Which ones did you try?

    This thread answered my question.

    Make Captivate play again after pausing - with Javascript

    Which basically restates what the OP says, that the "Continue Playing Project" check box has to be checked. And when its checked, you don't need any script to play the movie, Captivate will do that for you.

    I use the pause the same as you but use: window.cpCmndResume = 1; to play the movie again. I must have encountered the same issue as you some time ago, I don't remember. I have the same basic script file I use for all of our courses and they all use the resume command. I do check if at the end of the slide before issuing the command though.

      Thanks for the assistance.  This also did not work.  In fact I have now figured out that pause also does not work.  It always pauses on load since there is a text entry box.  From there its behavior is following the "Continue playing the project" option.  If it's checked it continues regardless of what I do, and if it's unchecked it stays pauses and won't continue.

      It's processing all of my other script.  Alert boxes show up, or if I set a variable in a text caption it changes accordingly, but its like it's ignoring any play controls.

      I've tried window.cpAPIInterface.pause()/play()

      I've tried window.cpCmndResume = 1

      I've tried cp.setvariable("rdcmndResume","1")

      Nothing seems to be working.  Guess maybe I should try and get it working with internal captivate controls but since I plan to take everything collected and dump it into a google sheet I really need to figure out why javascript is not playing along nicely.

      Thanks!
