loader - jquery - removing loading div after the page has loaded -


so created simple method put loader. put loader , put opacity of main container tag 0.4 . when page loads, javascript doesn't remove loader , set opacity 1. code here:

important notes:
use jquery version 2(i don't know exact) 

$(document).ready(function() {        $(this).load(function() {           $('.progress').hide();           $('body').css("opacity", "1");        });     });

you should use $(window).load() not $(document).load()

$(document).ready(function(){    $(window).load(function(){      alert("this can run");    });    $(this).load(function(){      alert("this cannot run");    });    $(document).load(function(){      alert("this cannot run too");    });  })

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } &l
