目前我正在为我的公司开发一个web应用程序，最近开始学习JS / Jquery。我在下面的github链接中设置了Tabs插件/库中的内容：

正常情况下，标签在第142行上设置为onclick：
$currentTab.click(function () {
我已将标签更改为悬停，因为我更喜欢我的应用程序，如下所示：
$currentTab.hover(function () {
它在我的桌面上工作正常但是当我将浏览器的大小调整为较小的分辨率时，标签会以手风琴的形式发生变化。通常情况下它完全正常，但因为我已将它改为悬停系统，所以它现在不是最佳选择。有没有办法在javascript / jquery中检测较小的分辨率，所以当它在800px下的功能变回$currentTab.click(function () {时？或者我的问题的任何其他解决方案？
我想要的：根据分辨率更改jquery悬停事件功能或根据分辨率更改JS脚本（所以我创建2个js文件，一个用于移动设备，一个用于桌面，然后决定我将加载哪个脚本）。 / p>
答案 0 :(得分：0)
创建一个命名函数并执行
if (window.screen.width < whatever ) $currentTab.click(doIt);
else $currentTab.hover(doIt);
