H5开发：手机访问www如何自动跳转到m

第一种方法：

<script>

if(navigator.platform.indexOf('Win32')!=-1){

//pc

//window.location.href="电脑网址";

}else{

//shouji

window.location.href="手机网址";

}

</script>

第二种方法：

<script type="text/javascript">

function browserRedirect() {

var sUserAgent= navigator.userAgent.toLowerCase();

var bIsIpad= sUserAgent.match(/ipad/i) == "ipad";

var bIsIphoneOs= sUserAgent.match(/iphone os/i) == "iphone os";

var bIsMidp= sUserAgent.match(/midp/i) == "midp";

var bIsUc7= sUserAgent.match(/rv:1.2.3.4/i) == "rv:1.2.3.4";

var bIsUc= sUserAgent.match(/ucweb/i) == "ucweb";

var bIsAndroid= sUserAgent.match(/android/i) == "android";

var bIsCE= sUserAgent.match(/windows ce/i) == "windows ce";

var bIsWM= sUserAgent.match(/windows mobile/i) == "windows mobile";

if (bIsIpad || bIsIphoneOs || bIsMidp || bIsUc7 || bIsUc || bIsAndroid || bIsCE || bIsWM) {

window.location.href= '手机网站地址';

} else {

window.location= '电脑网站地址';

}

}

browserRedirect();

</script>

第三种方法：

<script type="text/javascript">

var mobileAgent = new Array("iphone", "ipod", "ipad", "android", "mobile", "blackberry", "webos", "incognito", "webmate", "bada", "nokia", "lg", "ucweb", "skyfire");

var browser = navigator.userAgent.toLowerCase();

var isMobile = false;

for (var i=0; i<mobileAgent.length; i++){ if (browser.indexOf(mobileAgent[i])!=-1){ isMobile = true;

//alert(mobileAgent[i]);

location.href = '手机网址';

break; } }

</script>

第四种方法：

<?php

////这段放手机站里

header("Cache-Control: no-cache");

header("Pragma: no-cache");

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);

$uachar = "/(symbianos|android|Mac OS|ucweb|blackberry)/i";

if($ua != '' && !preg_match($uachar, $ua)){

echo 'window.location.href="电脑地址";';

exit();

}

?>

<?php

//这段放在网站里

header("Cache-Control: no-cache");

header("Pragma: no-cache");

$ua = strtolower($_SERVER['HTTP_USER_AGENT']);

$uachar = "/(symbianos|android|Mac OS|ucweb|blackberry)/i";

if($ua != '' && preg_match($uachar, $ua)){

echo 'window.location.href="手机地址";';

exit();

}

?>

第五种方法：

<?php

function UserAgent(){

$user_agent = ( !isset($_SERVER['HTTP_USER_AGENT'])) ? FALSE : $_SERVER['HTTP_USER_AGENT'];

return $user_agent;

}

//Mobile

if ((preg_match("/(iphone|ipod|android)/i", strtolower(UserAgent()))) AND strstr(strtolower(UserAgent()), 'webkit')){

header('Location: 手机网址');

exit;

}else if(trim(UserAgent()) == '' OR preg_match("/(nokia|sony|ericsson|mot|htc|samsung|sgh|lg|philips|lenovo|ucweb|opera mobi|windows mobile|blackberry)/i", strtolower(UserAgent()))){

header('Location: 手机网址');

exit;

}else{//PC

header("Location: 电脑网址");

}

?>

第六种方法，也可以把名为uaredirect的文件下载到自己网站上引入；
