How to get the correct window width on orientation change for android devices both tablets and mobiles

问题

I am trying to calculate the window width on orientation change for android devices using jquery function $(window).outerWidth(true);. This calculation gives correct width on orientation change for both iphone and ipad but not in android. If i initially load the page in landscape mode or portrait mode i am getting the correct width but once i change the orientation after loading the page i am getting the width for portrait mode as was in landscape mode and vice versa. Please suggest what is happening and how can i handle this issue so that i get the correct window width on orientation change in android device

回答1:

Why not just use the javascript screen object. you should be able to get the screen dimensions with :

screen.height;
screen.width;

I was also stuck in this problem and find the best solution which will work on all the platforms.Below is the code of 'orientationchange' event.

function onOrientationChange(event)
{
    setTimeout(function(){
       'Enter you code here';
    },200);
}

Hope, it will help you and most of other too.. Cheers.

回答5:

Instead of listening to orientationchange event , you can listen to window resize event , it will make sure that window.innerHeight/outerHeight properties got updated.

回答6:

Try window.innerWidth, respectively, window.innerHeight; It is posible that android doesn't not about outerWidth and Height;

回答7:

This is ugly, but it works. Mobile viewport height after orientation change

window.addEventListener('orientationchange', () => {
  const tmp = () => {
    this.onResize()
    window.removeEventListener('resize', tmp)
  }
  window.addEventListener('resize', tmp)
})
