vue中js让悬浮菜单div循环上下移动

封装的方法：

runEle() {
  const thisTemp = this
  const suspendmenuentrydiv = document.getElementById('suspendmenuentrydiv')
  const initValue = 66
  // 初始化一个不然好像获取不到
  suspendmenuentrydiv.style.bottom = initValue + 'px'
  let flag = true // 切换条件
  const num = 50 // 加到最大值
  let start = 0 // 起始值
  let isMove = true
  // 鼠标放上去就停止移动
  suspendmenuentrydiv.onmouseover = function() {
    isMove = false
  }
  // 鼠标移出就继续移动
  suspendmenuentrydiv.onmouseout = function() {
    isMove = true
    // 移出的时候把菜单设置为关闭
    // thisTemp.isShow = false
  }
  suspendmenuentrydiv.onmouseleave = function() {
    isMove = true
    // thisTemp.isShow = false
  }
  setInterval(function() {
    if (isMove) {
        if (flag) {
          start = start + 1
          if (start === num) {
              flag = false
          }
        } else {
          start = start - 1
          if (start === 0) {
              flag = true
          }
        }
        // 移出中把菜单设置为关闭试试
        thisTemp.isShow = false
        suspendmenuentrydiv.style.bottom = (initValue + start) + 'px'
    }
  }, 90)
}

使用的时候调用一下方法即可

mounted() {
  this.runEle()
}
