Question

php或js如何判断： 当电脑访问手机页面时自动跳转到PC版网页！

不是手机访问电脑版的跳转哈！
<script type="text/javascript">
var pcAgent = new Array("chrome","compatible","firefox");
var browser = navigator.userAgent.toLowerCase();
var ispc = false;
for (var i=0; i<pcAgent.length; i++){ if (browser.indexOf(pcAgent[i])!=-1){ ispc = true;
//alert(mobileAgent[i]);
location.href = 'http://ww.baidu.com;
break; } }
</script>

之前用这个代码，如小米之类手机访问他也跳转到电脑版了....!

Answer 1

<script type="text/javascript">
function IsPhone() {
var userAgentInfo = navigator.userAgent;
var Agents = ["Android", "iPhone",
"SymbianOS", "Windows Phone",
"iPad", "iPod"];
var flag = false;
for (var v = 0; v < Agents.length; v++) {
if (userAgentInfo.indexOf(Agents[v]) > 0) {
flag = true;
break;
}
}
return flag;
}
if (IsPhone()) {
window.location ="http://m.baidu.com";
};
</script>
这是如果是手机访问跳转到m.baidu.com，如果是要匹配pc的话 改false和true就行

是手机页面，用电脑访问它是跳转到pc.a.com

亲，这里有个问题！ 此页已是手机页m.php.com 那用这个代码，当手机访问它不是在m.php.com循环刷新？

追答

你创建一个控制器。先访问这个文件。这个文件会自动跳转到手机或者pc

追问

这个就是没有解决目前的问题啊！你说的结构我懂！ 就是由:控制器，PC和mobile构成…… 而我要解决的是用户直接用电脑访问mobile的问题

追答

那你创建个头部加载时先运行这个文件不久行了，无非是跳了三次
