我是新手(开玩笑吗?！)，我无法使它正常工作.我在这里做错了什么? 如果屏幕宽度大于480，我不希望此功能执行任何操作，仅在屏幕宽度为480及以下时才触发.

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'); }); }); }

推荐答案

由于屏幕大小可以更改(如果用户重新调整窗口大小)，那么在事件中包含if语句是否更有意义?

Because screen size can change (if a user re-sizes the window), would it be more relevant to have the if statement within the event?

查看示例:

$(document).ready(function(){ $(".reklam").click(function(){ if ($(window).width() < 480) { $('.reklam').attr('src','bilder/480/reklam_on.jpg'); } }); });
