performance - Cache Javascript libraries across websites -


i want share idea you.

there many websites use sort of javascript library / framework (think jquery, angular, bootstrap). using these libraries can slow down page load, why don't cache them , use them later on different sites?

a website should able tell browser libraries (+version) wants use. browser handles package management (keep them date , remove old unused ones) bower or npm.

i made quick firefox extension proof concept, native browser implementation better of course. addon more explanation can found here: https://github.com/ovanschie/backage-firefox-addon

i'm confident can speed page loading , decrease bandwidth usage (especially on mobile devices).

what think?

would implement in of sites if browsers support it?

browsers cache libraries , cdns exist this. googles hosted libraries: https://developers.google.com/speed/libraries/

browsers cache files based on url.

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; } ...
