Simplifying Event Listener Assignment for Multiple Elements
You may encounter a situation where you need to add event listeners to multiple elements. While it's possible to assign listeners individually as shown:
element1.addEventListener("input", function() { // This function does stuff });
or by chaining conditional statements:
element1 && element2.addEventListener("input", function() { // This function does stuff });
these methods can become tedious when dealing with many elements. A more efficient approach is to utilize the forEach() method on an array of the elements:
let elementsArray = document.querySelectorAll("whatever"); elementsArray.forEach(function(elem) { elem.addEventListener("input", function() { // This function does stuff }); });
By iterating through the array, this code assigns the event listener to each element in a single line, simplifying your code and streamlining the event-handling process.
