Hype Javascript Function Control

Hello everyone,

I’m curious to know if someone may have any ideas on how to trigger a clearInterval on a scene unload.

The Javascript code I am using makes dots on the page go from invisible to visible. I have a setInterval checking a number every 100 milliseconds. When the scene unloads, I would like to run a function that triggers a clearInterval.

Below is the code I am currently using:

    var mph = setInterval(function(){ check() }, 100); function check() {var speedo = parseInt(document.getElementById("speed").innerHTML, 10); console.log(speedo);if(speedo <= 0){hypeDocument.getElementById("dot1").style.opacity = "1";} if(speedo >= 1){hypeDocument.getElementById("dot2").style.opacity = "1";} else {hypeDocument.getElementById("dot2").style.opacity = "0”;}

Any ideas?


make your mph global. explicit with window.mph or just mph. this way you should be able to access it …

Hi Hans! Thanks for the rapid reply!

I am a total beginner in Javascript, but am getting better everyday! How can I go about making the mph variable global?

Thanks again!!

mph = ...


window.mph = ...

google or search this forum for the differences …
as far as i remember mraddy did a good explanation…


You are a saint! Thank you so much!

Thank you again!!
