如何判断是从PC端还是移动端进入

window.location.href = /Android|webOS|iPhone|iPad|iPod|BlackBerry|Windows Phone/i.test(navigator.userAgent) ? 'http://www.baidu.com':'http://news.baidu.com'

 

js:

　　

function detectmob() {
if( navigator.userAgent.match(/Android/i)
|| navigator.userAgent.match(/webOS/i)
|| navigator.userAgent.match(/iPhone/i)
|| navigator.userAgent.match(/iPad/i)
|| navigator.userAgent.match(/iPod/i)
|| navigator.userAgent.match(/BlackBerry/i)
|| navigator.userAgent.match(/Windows Phone/i)
){
return true;
}
else {
return false;
}
}
alert(detectmob());
