用Js判断客户端是PC还是手持设备

 function IsPC()
{
var userAgentInfo = navigator.userAgent;
var Agents = new Array("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;
}
