Will $(window).resize() fire on orientation change?

Im using this to run some code when a browser window is resized: $(window).resize(callback)

I also need to run this code when the orientation is changed in phones and tablets. Will the above fire on this event?


Solution 1:

Some devices/browsers do, some not. You need to decide your supported browsers and devices.

If you want to be on secure side you should use the resize event and get/check the sizes inside in it; if you know your desired devices go with a simple orientation change:

Easy solution:

// Listen for orientation changes      
window.addEventListener("orientationchange", function() {
    // Announce the new orientation number
    alert(window.orientation);
}, false);

More secure/supported

// Listen for resize changes
window.addEventListener("resize", function() {
    // Get screen size (inner/outerWidth, inner/outerHeight)

}, false);

David Walsh wrote a good article about resize and orientation change event. More about orientation change and sizes here: http://davidwalsh.name/orientation-change

Solution 2:

the answer is imho: no

but:

$(window).on('resize orientationchange', function(){
//do stuff
});

should have you covered

careful, this can trigger twice depending on the browser

Solution 3:

My solution:

  1. Generate an event when orientationchange doesn't do it
  2. use a throttle to prevent to much update on resize (lodash library for instance)

window.addEventListener("resize", throttle(function() {
    //to do when resize
}, 50), false);

window.addEventListener("orientationchange", function() {
    // Generate a resize event if the device doesn't do it
    window.dispatchEvent(new Event("resize"));
}, false);

Solution 4:

Quirksmode directly tested this question and found that the native resize event fired on orientation change in all browsers other than Opera Mini: https://www.quirksmode.org/dom/events/resize_mobile.html
