问题 I'm a newbie (no kidding?!) and I can't get this to work. What am I doing wrong here? If the screen width is larger than 480 I don't want this function to do anything, only to fire when screen width is 480 and below. if ( screen.availWidth < 480 ) { $(document).ready(function(){ $(".reklam").click(function(){ $('.reklam').attr('src','bilder/480/reklam_on.jpg'); }); }); } 回答1: Because screen size can change (if a user re-sizes the window), would it be more relevant to have the if statement
