tysonmatanich / viewportsize Goto Github PK

Hi all,
I have found that the viewport presents in 2 types:

1. The visual viewport
2. The viewport of page
   Please read this answer http://stackoverflow.com/a/6333966/2906042

So, your script defines the visual viewport. I think, you have to mention about that in description of your project. If you have any questions, please don't hesitate ask me, my email: [email protected]

I just came across your blog post http://www.matanich.com/2013/01/07/viewport-size/

What do you think of this approach?

var getViewportSize = function(fn) {
  var div = document.createElement('div');
  div.style.cssText = 'background:red;position:fixed;top:0;right:0;bottom:0;left:0;';

  document.body.appendChild(div);

  var rect = div.getBoundingClientRect();

  fn({
    width: rect.right - rect.left,
    height: rect.bottom - rect.top
  });

  document.body.removeChild(div);
}

getViewportSize(function(size) {
    console.log(size);
});

Size is incorrect when used on iOS6 Safari. When you scroll on Safari to see rest of page, the top toolbar disappears, and viewport height becomes higher.

Yes, it is defined in the readme file but no license file exists.

I am trying to check how it works . This is my code:

But I am not getting it worked. Can anyone please help? Thanks in advance.

Getting different values in the latest version of chrome on pages with or without scrollbars. The actual CSS viewport size seems unaffected.

Getting consistent values in IE10.

Wouldn't something like this work? This is not optimized at all, but the logic should be solid.

function browserWidth() {
    if(window && 'innerWidth' in window) {
        var innerWidth = window.innerWidth;
    }

    if(document && document.documentElement && 'clientWidth' in document.documentElement) {
        var clientWidth = document.documentElement.clientWidth;
    }

    if(typeof innerWidth !== "undefined" && typeof clientWidth !== "undefined") {
        return Math.min(innerWidth, clientWidth);
    }

    if(typeof innerWidth !== "undefined") {
        return innerWidth;
    }

    if(typeof clientWidth !== "undefined") {
        return clientWidth;
    }

    if(document && document.getElementsByTagName('body')[0] && document.getElementsByTagName('body')[0].clientWidth) {
        return document.getElementsByTagName('body')[0].clientWidth;
    }

    return null;
}

Something like:
window.innerWidth && document.documentElement.clientWidth ? Math.min(window.innerWidth, document.documentElement.clientWidth) : window.innerWidth || document.documentElement.clientWidth || document.getElementsByTagName('body')[0].clientWidth;

Thanks.
