如何运行此 jquery 仅在桌面上运行

Question

我是 Javascript 的初学者，我需要您帮助我编写这个 Jquery 脚本..

我需要让它只在桌面上工作并阻止它在tablet/mobile中运行。

如果有人能帮我解决这个问题那就太好了。非常感谢！

<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>

Answer 1

你可以写一个 javascript 函数来 returns 用户是否在桌面设备上来自用户代理。

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
  );
}

Answer 2

您可以使用以下代码：

 <script>
  var isDesktop = true;
  if (
    /(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|ipad|iris|kindle|Android|Silk|lge |maemo|midp|mmp|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino/i.test(
