将如下代码加在网页标题头部，，即可实现手机客户端访问时自动跳转到wap目录下：
<script language="javascript">
function is_mobile() {
var regex_match = /(nokia|iphone|android|motorola|^mot-|softbank|foma|docomo|kddi|up.browser|up.link|htc|dopod|blazer|netfront|helio|hosin|huawei|novarra|CoolPad|webos|techfaith|palmsource|blackberry|alcatel|amoi|ktouch|nexian|samsung|^sam-|s[cg]h|^lge|ericsson|philips|sagem|wellcom|bunjalloo|maui|symbian|smartphone|midp|wap|phone|windows ce|iemobile|^spice|^bird|^zte-|longcos|pantech|gionee|^sie-|portalmmm|jigs browser|hiptop|^benq|haier|^lct|operas*mobi|opera*mini|320x320|240x320|176x220)/i;
var u = navigator.userAgent;
if (null == u) {
return true;
}
var result = regex_match.exec(u);
if (null == result) {
return false
} else {
return true
}
}
if (is_mobile()) {
document.location.href= '/wap';
}
</script>
