JavaScript question

[Vico Eventuin]

I want to build an interaction with JS. I want to use a button to increase the value of a number of a meter as long as the button is clicked and hold it. On release of the button the number has to stay at the last value. Pushing and holding it again has to further increae the value.

How to build this with Some JS in CP?

Help is very Welcome!

One more challenge.

I would like the number (myVal) to always have 2 digits, so not 1, 2, 3 etc but 01, 02, 03 etc.

Any ideas?

Hmmm

You'll have to do the incrementing, then if the value is only a single digit, cast the value to a string before passing it back to Captivate. That'll need another variable in the js.

Something like this:

function buttonPressUp() { //prevents values higher than 99

var jsVal = parseInt(window.myVal); //read the value of myVal from CP and cast it to an integer

    if (window.jsVal < 99) {

          cp.hide("img1");

          cp.show("img2");

        timer = setInterval(function () {

            jsVal++;

             if(jsVal < 10){

                    window.myVal =  "0" + jsVal.toString(); //cast jsVal to a string and append a zero in front

             }

             else {window.myVal = jsVal;

            }

            if (jsVal > 98) {

                clearPress();

            }

        }, 100);

    }

}

Oops - the first if statement should read

if(jsVal < 00){

Sorry!

Don't know why the system isn't letting me edity my own comments.

Let's try that again:

if(jsVal < 99){
