前阵子写了个小工具，后来经过经理的审核后给了我几个改进的建议，第一是简化界面，这个工具将来会用手机来进行管理，所以界面上要尽量简化，省去不必要的组件，第二是使用jquery mobile来美化界面，第三是使用ajax post方式来提交数据，避免传统的post方法重载整个页面。
第一，我加上了检测客户端设备的页面为首页,这样就能在访问首页的时候根据设备来做重定向，
此代码参考了csdn里某大牛的文章，做了部分修改，原文出自这里：链接
index.php代码为：
<?php
function is_mobile(){
$regExp="/mobile|nokia|iphone|ipad|android|samsung|htc|motorola|blackberry|ericsson|huawei|dopod|amoi|gionee|^sie\-|^bird|^zte\-|haier|";
$regExp.="blazer|netfront|helio|hosin|novarra|techfaith|palmsource|^mot\-|softbank|foma|docomo|kddi|up\.browser|up\.link|";
$regExp.="symbian|smartphone|midp|wap|phone|windows ce|CoolPad|webos|iemobile|^spice|longcos|pantech|portalmmm|";
$regExp.="alcatel|ktouch|nexian|^sam\-|s[cg]h|^lge|philips|sagem|wellcom|bunjalloo|maui|";
$regExp.="jig\s browser|hiptop|ucweb|ucmobile|opera\s*mobi|opera\*mini|mqqbrowser|^benq|^lct";
$regExp.="480×640|640x480|320x320|240x320|320x240|176x220|220x176/i";
if(!isset($_SERVER[‘HTTP_USER_AGENT‘])){
return true;
}else{
return @$_GET[‘mobile‘] || isset($_SERVER[‘HTTP_X_WAP_PROFILE‘]) || isset($_SERVER[‘HTTP_PROFILE‘]) || preg_match($regExp, strtolower($_SERVER[‘HTTP_USER_AGENT‘]));
}
}
?>
<?php echo ‘you are ‘.(is_mobile()? ‘mobile‘ : ‘desktop‘).‘ user, redirecting...‘;?>
<?php is_mobile()? $rd_link=‘mobile.php‘ : $rd_link=‘desktop.php‘;
echo $rd_link;
header("Location:$rd_link");
?>第二，桌面版界面我改成这样了
跟之前的对比：
是不是简洁了很多？
desktop.php
桌面版主要使用jquery的document.ready来检测事件，使用传统的post提交数据

效果图:
有木有发现按钮和选择框都被放大了很多？这是主要为了显示在手机上而优化的，直接应用了jquery
mobile的库，mobile.php代码如下：
<html>
<head>
<meta name="viewport" content="width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no" />
//这一行很管用，主要是在手机里能100%显示并禁止缩放界面
