应该把JS 放在页面首页加载 就行function IsPC() {
var userAgentInfo = navigator.userAgent
var Agents = ["Android", "iPhone",
"SymbianOS", "Windows Phone",
"iPad", "iPod"]
var flag = true
for (var v = 0v <Agents.lengthv++) {
if (userAgentInfo.indexOf(Agents[v]) >0) {
flag = false
break
}
}
return flag
}
var flag = IsPC()//true为PC端，false为手机端
alert(flag)
