How to Mobile blogger site redirecting to desktop when shared from mobile:

<script type="text/javascript">
    var addthis_share = {
        url: "<data:view.url.canonical/>",
    }
</script>

The Conditional expression has the following syntax which works on a Boolean Logic:

<b:if cond='data:blog.isMobileRequest == "true"'>
HTML To Show Only in Mobile Devices
</b:if>

The content inside the conditional expression above will load only in Mobile devices where the condition has value true due to the parameter ?m=1 where 1 means True.

If in case you wish to display a content only on desktop devices then you will reverse the logic in this order:

<b:if cond='data:blog.isMobileRequest == "false"'>
HTML To Show Only in Desktop Devices
</b:if>

As simple as that. Note that this condition works irrespective of whether or not you have enabled or disabled the default Blogger Mobile template. You can use it in both cases.

------------------------------------------------------------------

if (screen.width < 960) {
    alert('Less than 960');
}
else {

    alert('More than 960');
}

------------------------------------------------------

if ($(window).width() < 480 || $(window).height() < 480) {
    //small screen, load other JS files
    $.getScript('/js/script.js', function () {
        //the script has been added to the DOM, you can now use it's code
    });
}

<script>
if(!/Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) && location.search.match("m=1") != null) 
{
location.search = location.search.replace('m=1','m=0')
}
