JS获取cookie

function getCookie(name) {
  if (document.cookie.length > 0) {

    const end = `${name}=`
    const cal = document.cookie.split(';')
    for (let i = 0; i < cal.length; i += 1) {
      const str = cal[i].trim()
      if (str.substring(0,end.length) === end) return str.substring(end.length,str.length)
    }
  }
  return '';
}
