Question: What is the best solution for this problem? Answer: This blog code can help you solve errors How to Differentiate Single and Double Click Events in JavaScript. Question: “What should you do if you run into code errors?” Answer:”You can find a solution by following this blog.

I needed a way to detect both single and double clicks on my website.

I used both event listeners below:

document.addEventListener("click", handleClick);
document.addEventListener("dblclick", handleClick);

Unfortunately, the dblclick event handler wouldn’t prevent the click event handler from firing, so every double click was preceded by a single click.

In order to fix this, I removed the dblclick handler completely and began checking for double clicks within the click handler.

let numClicks = 0;
const handleClick = () => {
  if (numClicks === 1) {
    singleClickTimer = setTimeout(() => {
      numClicks = 0;
      console.log("single click!");
    }, 400);
  } else if (numClicks === 2) {
    numClicks = 0;
    console.log("double click!");
document.addEventListener("click", handleClick);

numClicks is a global count variable for the number of clicks that have occurred so far.

The first click will always trigger the timer singleClickTimer, which runs for 400ms. If a second click happens within that 400ms, then a double click will be registered, and the timer (as well as the callback) will be cleared.

The downside to this approach is that it will always take 400ms to register a single click event.

We can decrease the 400ms to a smaller number to force single clicks to register faster, but this will also force double clicks to be quicker as well.

Revise the code and make it more robust with proper test case and check an error there before implementing into a production environment.
