Question

检测访问网站是pc端还是手机端用户

Answer 1

JS判断是手机访问还是PC端访问网站
<script>
if ((navigator.userAgent.match(/(iPhone|iPod|Android|ios|iOS|iPad|Backerry|WebOS|Symbian|Windows Phone|Phone)/i))) {
location.replace("http://m.helloweba.com")
}else{
document.write("请使用手机访问.");
}
</script>

百度的判断代码

复制代码 代码如下:

function uaredirect(f) {
try {
if (document.getElementById("bdmark") != null) {
return
}
var b = false;
if (arguments[1]) {
var e = window.location.host;
var a = window.location.href;
if (isSubdomain(arguments[1], e) == 1) {
f = f + "/#m/" + a;
b = true
} else {
if (isSubdomain(arguments[1], e) == 2) {
f = f + "/#m/" + a;
b = true
} else {
f = a;
b = false
}
}
} else {
b = true
}
if (b) {
var c = window.location.hash;
if (!c.match("fromapp")) {
if ((navigator.userAgent.match(/(iPhone|iPod|Android|ios|SymbianOS)/i))) {
location.replace(f)
}
}
}
} catch(d) {}
}
function isSubdomain(c, d) {
this.getdomain = function(f) {
var e = f.indexOf("://");
if (e > 0) {
var h = f.substr(e + 3)
} else {
var h = f
}
var g = /^www\./;
if (g.test(h)) {
h = h.substr(4)
}
return h
};
if (c == d) {
return 1
} else {
var c = this.getdomain(c);
var b = this.getdomain(d);
if (c == b) {
return 1
} else {
c = c.replace(".", "\\.");
var a = new RegExp("\\." + c + "$");
if (b.match(a)) {
return 2
} else {
return 0
}
}
}
};

使用方法：
<SCRIPT type=text/javascript>uaredirect("手机站","WEB站");</SCRIPT>
