Playing Audio Using Keystrokes: Is It Possible?

Annabelle5893

Gold Coder
I'm wondering, how would I make an app that plays audio files using the keys on the number pad? Specifically, I want to make an app that triggers "Rotary Pulse 1" by pressing 1 on the numeric keypad, all the way up to "Rotary Pulse 0" on the 0 key. A dial tone will be toggled on by pressing the spacebar, which will begin with a "receiver pickup" noise. The dial tone turns off when digits are dialed via the numeric keypad. If you press the spacebar either when the dial tone is on, or after dialing a number, a "Receiver Hang Up" noise will be triggered. With the rotary dial sounds, the dial turning to the fingerhole is triggered at key down, and the release of the dial returning to the resting position will be triggered by releasing of the number corresponding to the fingerhole (1, 2, 3, 4, 5, 6, 7, 8, 9, 0). This will be accompanied by the internal sound of the dial pulses as heard in a telephone. What is the code I would use to make this audio app using HTML?
 
Let me clarify my question a bit: Do you really have an html element with that id?
There's a function with that name, and an element called "hookswitchStatus", which is on the hookswitch itself.
Code:
<div role="switch" aria-labelledby="id-label">
  <label for="Hookswitch Status"
  <button type="button"
          role="switch"
  id="hookswitch">Hookswitch Status: 
    <span class="hookStatus off">
    </span>
  </label>
  </button>
</div>

So, according to the code you posted, you do not have an element with the id of "toggleLineStatus", which is what the error is telling you.
 
The "Hookswitch" switch, which is supposed to be toggled when you press the spacebar, is supposed to play certain sounds when switched on and others when switched off.
But we weren't talking about the switch though, we were talking about the element that you are missing, with an id of 'toggleLineStatus'
 
This one?
Code:
function toggleLineStatus() {
That's a function. I am assuming you are using it somewhere in your code.

Let's go back to the line of error and break the code down.
JavaScript:
document.getElementById('toggleLineStatus')

That line: document, refers to the html document, aka the page itself. The function getElementById is a javascript built-in function, that allows you to access HTML Elements in javascript, using the element attribute 'id'.

The function is used to toggle between "On Hook", and "Off Hook" by pressing Spacebar. When "Off Hook", the Dial Tone plays. When on hook, all audio stops. the "RingTelephone" function may be triggered when On Hook. When answering by pressing Spacebar, you can use your microphone to talk, like you're on the phone. I know it sounds a bit complicated, right?

Ok, but I am not sure how that is relevant to the actual issue here. The issue is that you are trying to access an HTML ELEMENT that has the attribute "id" woth a value of "toggleLineStatus", which you do not have in your HTML.

in other words, you need to create an element like this, as an example:
HTML:
span id="toggleLineStatus" class=""

very close. But let me take a step back myself and ask you this: So in the code in question, you are setting up an onclick event, which in essence is an event listenter... when this is fired off, the function toggleLineStatus() is called. The question here is: what exactly were you intending to click when you are using this line:


JavaScript:
document.getElementById('toggleLineStatus').onclick=function(){
    toggleLineStatus()
};

I want to be able to toggle the hookswitch by pressing the spacebar.
