Force browser update if IE8 or older
问题 I wonder if it's possible to show a warning or open a pop-up, which would say update your IE to latest version or use Firefox / Chrome / Safari instead, when browser is Internet Explorer IE8 or older... I guess I should use that code below inside the tags... <!--[if lt IE 9]> ...i should use code here... <![endif]--> Is it smart to deceted browser with jQuery and loading jQuery lib? Or is it better to just use regular javascript in order to avoid additional issues with very old browsers? 回答1:
