monitoring the browser resolution changes by observing window.innerWidth using the $watch method in JavaScript

I am looking to retrieve the current screen resolution of my clients' browsers for calculation purposes. The function I plan to use is as follows:

  scope.$watch('**??what,should,go,here??**', function() {
     scope.screen = (window.innerWidth / 2) - 150;
  });

While attempting to use a regular $watch function, I encountered an issue with determining what exactly to watch. Initially, I tried watching window.innerWidth but found this approach to be ineffective as it only provides a value once. I believe there must be a simpler solution that I'm overlooking.

Any assistance would be greatly appreciated. Thank you.

Answer №1

Attach to onresize, for example.

window.addEventListener("resize", function () {
    // verify width
});

Answer №2

Utilize this method

 window.addEventListener("resize", function () {
     // your scripts go here
 }

If you aim to style the page based on window size, incorporating .clientWidth along with it would be the solution

window.addEventListener("resize", function () {
    if (document.clientWidth < 900) {
        // additional scripts
     }
}

Alternatively, for styling purposes, CSS can be utilized with @media queries as demonstrated below

@media (max-width: 900px) and (min-width: 300px) {
    // Your CSS styling here
}

Answer №3

Another option is to utilize the following method:

window.onresize = adjustOnResize;

function adjustOnResize() {
// add your code here
}
