JavaScript code specifically designed for mobile and tablet devices only

I seem to be facing a challenge with a JavaScript script that is being used on a menu. The menu is styled differently for desktop and smaller devices, and I would like the script to only impact the menu when the screen width is less than a certain value. How can I make this happen? Here's the script:

    var dropdown = document.getElementsByClassName("dropdown-btn");
    var i;

    for (i = 0; i < dropdown.length; i++) {
      dropdown[i].addEventListener("click", function() {
      var dropdownContent = this.nextElementSibling;
      if (dropdownContent.style.display === "block") {
      dropdownContent.style.display = "none";
      } else {
      dropdownContent.style.display = "block";
      }
      });
    }

Answer №1

Determine the width of the browser window in a cross-browser way and execute your script based on the conditions.

var screenWidthThreshold = 400,
windowWidth = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
if (windowWidth < screenWidthThreshold) {
  console.log(windowWidth, 'true')
  // Implement actions for smaller screens here
} else {
  console.log(windowWidth, 'false')
  // Implement actions for larger screens here
}

Answer №2

To determine the width of the window using JQuery, you can utilize the window property and the width method.

if ($(window).width() < x)
{
    //Add your code here
}

Answer №3

If you need to determine the width of a window in a cross-browser way, JavaScript offers a solution utilizing the window, screen, and width properties.

Here is an example that may be useful:

//Checking for smaller screen sizes
var size = 768; 
if(window.screen.width < size) {
    //Code for smaller screens can go here
}
else
{
    //Code for larger screens can go here
}
