获取当天日期的时间戳||日期相关的函数-蒲公英云

一、获取当天的时间戳

new Date(new Date().setHours(0, 0, 0, 0)).getTime()  //当天0点的时间戳
new Date(new Date().setHours(23, 59, 59, 999)).getTime()  //当天24点的时间戳

二、日期相关的封装函数

  // document[hiddenProperty] 可以判断页面是否失焦
  let names = ['hidden', 'webkitHidden', 'mozHidden', 'msHidden']
  names = names.filter(e => e in document)
  return names.length > 0 ? names[0] : false
})()
const visibilityChangeEvent = (() => {
  if (!hiddenProperty) {
    return false
  }
  return hiddenProperty.replace(/hidden/i, 'visibilitychange') // 如果属性有前缀, 相应的事件也有前缀
})()
export default {
