JS 判断是否移动端

javascript 判断是否移动端，代码如下：

function isMobile() {
  const userAgentInfo = navigator.userAgent
  const Agents = [
    'Android',
    'iPhone',
    'iPad',
    'iPod'
  ]
  let flag = false
  for (let v = 0; v < Agents.length; v++) {
    if (userAgentInfo.indexOf(Agents[v]) > 0) {
      flag = true
      break
    }
  }
  return flag
}
