在 jQuery 中几秒钟后显示和隐藏 div

Question

我有一些链接，当我将鼠标悬停在上面时会显示与该链接相关的特定文本。我使用悬停功能来显示和隐藏 div。

我还想添加一个功能，使文本在几秒钟后自动更改以显示下一个 div 的内容。即通过div循环。隐藏 div 1、显示 div 2、隐藏 2、显示 div 3 等。下面是显示悬停功能如何工作的代码。将鼠标悬停在右侧的链接上，左侧的文字会发生变化：

$(".o-c").hover(function() {
  $('.home-o-c').show();
  $('.home-i-t').hide();
}, function() {
  $('.home-o-c').hide();
  $('.home-i-t').show();
});

$(".c-f").hover(function() {
  $('.home-c-f').show();
  $('.home-i-t').hide();
}, function() {
  $('.home-c-f').hide();
  $('.home-i-t').show();
});

$(".i-c").hover(function() {
  $('.home-i-c').show();
  $('.home-i-t').hide();
}, function() {
  $('.home-i-c').hide();
  $('.home-i-t').show();
});


$(".c-u").hover(function() {
  $('.home-c-u').show();
  $('.home-i-t').hide();
}, function() {
  $('.home-c-u').hide();
  $('.home-i-t').show();
});

.left-fill {

.vc_col-sm-6 {
  width: 50%;

}

.pivot-nav {
  list-style: none;
  font-family: 'Montserrat';
  text-align: left;
}

.pivot-nav li a {
  font-size: 1.6rem;
  font-weight: 700;
  text-transform: uppercase;
  display: inline-block;
  position: relative;
  color: #fff;
  text-decoration: none;
  line-height: 40px;
}

.pivot-nav li a.default-underline::after,
.pivot-nav li a:hover::after {
  width: 100%;
}

.pivot-nav:hover a.default-underline:not(:hover)::after {
  width: 0;
}

.pivot-nav li a::after {
  bottom: 0;
  content: "";
  display: block;
  height: 4px;
  position: absolute;
  background: #fff;
  transition: width 0.3s ease 0s;
  width: 0;
}

你可以这样做：

var homeLinks = ['i-t', 'o-c', 'c-f', 'i-c', 'c-u'];
var currentLink = 0;
var hovered = false;

$(".home-link").hover(function() {
  hovered = true;
  $('.home-'+homeLinks[currentLink]).hide();
  $('[data-hover='+homeLinks[currentLink]+']').toggleClass('default-underline');
  currentLink = homeLinks.indexOf($(this).attr('data-hover'));
  $('[data-hover='+homeLinks[currentLink]+']').toggleClass('default-underline');
  $('.home-'+homeLinks[currentLink]).show();
}, function() {
  hovered = false;
});

var autoNavInterval = setInterval(autoNav, 1000);

function autoNav() {
  if(hovered === false){
    $('.home-'+homeLinks[currentLink]).hide();
    $('[data-hover='+homeLinks[currentLink]+']').toggleClass('default-underline');
    currentLink++;
    if(currentLink >= homeLinks.length){ currentLink = 0; }
    $('[data-hover='+homeLinks[currentLink]+']').toggleClass('default-underline');
    $('.home-'+homeLinks[currentLink]).show();
  }
}

.left-fill {
  background: #0000006b;
  height: 100vh;
}

.right-fill {
  background: pink;
  height: 100vh;
}

.vc_col-sm-6 {
  width: 50%;
  float: left;

.pivot-nav {

  font-family: 'Montserrat';

.pivot-nav li a {
  font-size: 1.6rem;
  font-weight: 700;
  text-transform: uppercase;
  display: inline-block;
  position: relative;
  color: #fff;

  line-height: 40px;
}

.pivot-nav li a.default-underline::after,
.pivot-nav li a:hover::after {
  width: 100%;
}

.pivot-nav:hover a.default-underline:not(:hover)::after {
  width: 0;
}

.pivot-nav li a::after {
  bottom: 0;
  content: "";

请注意，我在您的链接中添加了 data-hover 属性和 .home-link，这可以简化脚本...我使用 setInterval 自动显示功能，每 1 秒一次，但您可能想要更改它稍长一点，我创建了hovered var 作为标志，以了解鼠标当前是否位于链接上，并防止自动导航在链接悬停时更改显示的文本。
