AE Extension | Trigger 9 different functions with single button and keyboard Numpad 1-9

[manjunath MK]

I want 9 different functions to be triggered by single button and keyboard numpad (1-9) in my After effects extension. I got some solution from stackoverflow and it works fine in online html editors but doesn't work in after effects. Below is the sample code. Can someone plz help.

<button type="button" id="b41" onclick="myFunction(event)">myButton</button>
<script>
const pressedButtons = {};

window.onkeydown = (e) => (pressedButtons[e.which] = true);
window.onkeyup = (e) => (pressedButtons[e.which] = false);

function myFunction(event) {

if (pressedButtons[97]) {
setOpacity_0();
} else if (pressedButtons[98]) {
setOpacity_100();
} else {
setOpacity_50();
}
}
</script>

I'm not clear what you are asking. Your code does not contain any event listener that actually intercepts the key commands nor can I see anything pertaining to your functions/ button definitions. I suggest you actually look it up in the AE scripting docs or refer to useful tutorials like this:

This am not trying to achieve using  scriptUI.environment in jsx.

This am trying to get key pressed on cep panel button..

Functions ll be triggered using csinterface which I didn't mention in question.. Now am mentioning below.

<button type="button" id="b41" onclick="myFunction(event)">myButton</button>
<script>
const pressedButtons = {};

window.onkeydown = (e) => (pressedButtons[e.which] = true);
window.onkeyup = (e) => (pressedButtons[e.which] = false);

function myFunction(event) {

if (pressedButtons[97]) {
CSinterface.evalScript("setOpacity_0()");
} else if (pressedButtons[98]) {
CSinterface.evalScript("setOpacity_100()");
} else {
 CSinterface.evalScript(" setOpacity_50()");
}
}
</script>

Excuse me if any typo errors while typing the code. "setOpacity_50()" function just sets opacity of layer to 50 and this function in included in jsx script and it runs fine.. I don't have any prob in scripting. 

What I do is,I ll hold numpad1 and click the above button then it ll trigger function 1, and I hold numpad2 and click the above button then it ll trigger function 2.

.Hope u understand my concern now.. 

I didn't try with scriptUI.environment using cep panel and csinterface, let me  check anyways.  Thank you

I achieved thru scriptUI object only after button click thru CSinterface. I thought it would not work without even trying and was finding other ways.But, eventually the one which is already there is working fine. Thanks for enlightenment.
