The click event for getelementbyid() function is malfunctioning

I need assistance with a website I am creating that plays audio when a certain condition is met. Specifically, I want the audio to play if x falls within a specific range of numbers, but also continue playing if x does not fall within that range after the initial click. Unfortunately, I can't use jQuery because it doesn't work in Chrome. Here is my code:

if(x<=1200&&x>=600){
    var n=true;
};
if(x<=1200&&x>=600&&n==true){
    document.getElementById('a').onclick = function(){
        audio.play();
        n=false;    
    }
}
else{
    n=false;
}

Answer №1

The functionality of your code is to attach a click event listener to an element, and thereafter the click handler will execute regardless of the x value since there are no conditional checks within the click handler.

A better approach would be to set up the click listener only once and incorporate a check for the value of x within it. Here's an example:

document.getElementById('a').onclick = function(){
  if(x <= 1200 && x >= 600 && n == true) {
    audio.play();
    n = false;    
  }
}

Here's a demonstration (I've substituted audio playback with div highlighting, but the concept remains unchanged):

var r = document.getElementById('r');
var n = true;
var x = 1000;
document.getElementById('a').onclick = function(){
  if(x <= 1200 && x >= 600 && n == true) {
    r.className = 'playing';
    n = false;
    printN();
    setTimeout(function(){
      r.className = '';
    }, 2000);
  }
}

function toggleN(){n = !n;printN()}
function printN(){document.getElementById('n').textContent = 'n is set to ' + n;}
function randomizeX(){x = Math.floor(Math.random() * 1200);printX()}
function printX(){document.getElementById('x').textContent = 'x equals ' + x;}

#r {display: inline-block; width: 50px; height: 50px; background: #ccc; transition: background 1s linear;}
#r.playing {background: green}

<button id="a">Hit me</button><br><br>
<div id="r"></div>
<p id="x">x equals 1000</p>
<p id="n">n is set to true</p>
<button onclick="toggleN()">Toggle n</button>
<button onclick="randomizeX()">Randomize x</button>

It seems like you may be attempting to achieve a specific task, so here is a suggestion:

if(y<=1200&&y>=600){
    var m=true;
    var pressed = false;
    };
    if(y<=1200&&y>=600&&m==true || pressed==true){
    document.getElementById('b').onclick = function(){
    audio.play();
    m=false;
    pressed = true;
        }
    }
    else{
        m=false;
        pressed = false;
   }

It seems like this code will meet your requirements, based on my understanding of your request.

There is no need to repeatedly check x and n, as n only becomes true when x falls within the specified ranges.

var ab = document.getElementById('a');
var n = false;

if (x <= 1200 && x >= 600) {
  n = true; // Setting n to true when x is within range.
} else {
  n = false; // Resetting n if x goes out of range.
}

ab.onclick = function() {
  if (n) {
    audio.play();
  }
}

Please be aware that if a user clicks the button multiple times, the audio will play accordingly each time. To prevent this from happening, you may consider introducing another variable to track if the user has already clicked once. The solution for controlling repeated clicks depends on your specific setup and whether users should be able to trigger the audio multiple times in succession. Feel free to reach out with more details for a tailored solution.
