JavaScript悬停功能在按钮单击之前保持打开状态

时间：2017-06-19 18:07:49

标签： javascript html css

我在下面的代码中提供了一些使用HTML和CSS创建的信息框。是否可以让悬停div保持打开，直到单击关闭按钮？这可以在Vanilla JavaScript中做到吗？我是JavaScript的新手，所以任何事情都有帮助，欢呼！

答案 0 :(得分：1)

这有点长，但这里是fiddle。

基本上，您要为mouseenter（打开）和单击（关闭）事件定义几个事件处理程序，然后更改CSS以解决此问题。我会立即发布并解释更新中的每一位。

对于打开和关闭处理，您只需添加和删除＆＃34; hover＆＃34; class（而不是使用伪类）：

function open(e){
  let li = e.target;
  li.classList.add('hover');
}

function close(e){
  const hoverable = e.target.closest('li.hover');
  hoverable.classList.remove('hover');
}

然后在CSS中更改你的：hover pseudoclass以改为使用.hover：

.info-boxes li.hover .shade {
  animation-timing-function: cubic-bezier(0.215, 0.61, 0.355, 1);
  animation-duration: 1s;
  animation-iteration-count: 1;
  animation-fill-mode: forwards;
}

添加事件处理程序等很简单：

const infoBoxListItems = document.querySelectorAll('.info-boxes li');
const closeButtons = document.querySelectorAll('.profileclose');

infoBoxListItems.forEach(li => {
  li.addEventListener('mouseenter', open);
});

closeButtons.forEach(btn => {
  btn.addEventListener('click', close);
});

我的完整示例包含closest()的polyfill，但这是来自MDN的直接副本，因此您可以在那里阅读。
