MediaQueryList: removeListener() method

View on MDN ↗

The removeListener() method of the MediaQueryList interface removes a listener from the MediaQueryListener.

In older browsers MediaQueryList did not yet inherit from EventTarget, so this method was provided as an alias of removeEventListener(). Use removeEventListener() instead of removeListener() if it is available in the browsers you need to support.

Syntax

removeListener(func)

Parameters

  • func
    • : A function or function reference representing the callback function you want to remove.

Return value

None (undefined).

Examples

const paragraph = document.querySelector("p");
const mediaQueryList = window.matchMedia("(width <= 600px)");

function screenTest(e) {
  if (e.matches) {
    /* the viewport is 600 pixels wide or less */
    paragraph.textContent = "This is a narrow screen — 600px wide or less.";
    document.body.style.backgroundColor = "pink";
  } else {
    /* the viewport is more than 600 pixels wide */
    paragraph.textContent = "This is a wide screen — more than 600px wide.";
    document.body.style.backgroundColor = "aquamarine";
  }
}

mediaQueryList.addListener(screenTest);

// Later on, when it is no longer needed
mediaQueryList.removeListener(screenTest);
