JS实现判断移动端PC端功能

function IsPC() {
  var userAgentInfo = navigator.userAgent;
  var Agents = ["Android", "iPhone","SymbianOS", "Windows Phone","iPad", "iPod"];
  var flag = true;
  for (var v = 0; v < Agents.length; v++) {
    if (userAgentInfo.indexOf(Agents[v]) > 0) {
      flag = false;
      break;
    }
  }
  return flag;
}

if (/(iPhone|iPad|iPod|iOS|Android)/i.test(navigator.userAgent)) { //移动端
//TODO
}
