如何在桌面上运行这个jquery函数

Question

我是Javascript的乞丐，我需要你的帮助与这个Jquery脚本我正在工作..

我需要使它只在桌面上工作并防止它在平板电脑/手机上运行。

如果有人能帮我做这件事就太好了。

<script>
/*Project Collection Section*/
// Page Load
$('.grid-card').eq(0).addClass('current');
$('.grid2-item').eq(0).addClass('current');
$('.grid-image').eq(0).addClass('current');
function changeFocus(trigger) {
$('.current').removeClass('current');
trigger.addClass('current');
let myIndex = trigger.closest('.grid1-item').index();
$('.grid2-item').eq(myIndex).addClass('current');
$('.grid-image').eq(myIndex).addClass('current');
}
$('.grid-card').on('mouseenter', function() {
changeFocus( $(this) );
});
$('.scroll-trigger').on('inview', function(event, isInView) {
if (isInView) {
let myTrigger = $(this).closest('.grid-card');
changeFocus( myTrigger );
} else {
// do something else
}
});
</script>

可以使用以下代码:

<script>
var isDesktop = true;
if (

你可以写一个javascript函数来返回用户是否在桌面设备上。

你可以这样做

function isDesktop() {
const ua = navigator.userAgent;
return !/(tablet|ipad|playbook|silk)|(android(?!.*mobi))|(Mobile|Android|iP(hone|od)|IEMobile|BlackBerry|Kindle|Silk-Accelerated|(hpw|web)OS|Opera M(obi|ini))/.test(
ua
);
}
