      从2007年,乔布斯带来了第一代Iphone手机,整个移动互联网发生天翻地覆的变化,也同时证明了乔布斯的一句名言:“再一次改变世界”。

      在当今的移动互联网,手机App居多,很多App对移动设备的要求也越来越高,当然,土豪就可以经常更新换代。我们这群屌丝只能望梅止渴。为了解决少部分由于硬件或者软件引起的问题,我们将App迁移到浏览器上,也就是人们常说的WebApp,WebApp相对与手机App客户端有以下优点:

      1、免安装,一个浏览器就可以搞定。
      2、不需要繁忙的迭代更新。
      3、不需要担心存储不足无法安装。
      4、时刻可以享受最新的功能。
      5、轻量级App。
      6、跨平台
      7、...

    第一步:页面头部标签的申明
    ① 声明文档,在这里我们采用的是Html5的申明文档
    <!DOCTYPE html>

    ② 禁止浏览器缩放
    <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">

    ③ 设置浏览器编码类型
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta content="application/xhtml+xml;charset=UTF-8" http-equiv="Content-Type" />

    ④ 清除浏览器缓存
    <meta http-equiv="pragma" content="no-cache">
    <meta http-equiv="Cache-Control" content="no-cache, must-revalidate">
    <meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT">

    ⑤ iPhone 手机上设置手机号码不被显示为拨号链接
    <meta content="telephone=no, address=no" name="format-detection" />

    ⑥ IOS私有属性,可以添加到主屏幕
    <meta name="apple-mobile-web-app-capable" content="yes" />

    ⑦ IOS私有属性,网站开启对 web app 程序的支持
    <meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />

    第二步:解决IE6~IE9对Html5和Css3的支持问题
    ① 让IE6~8支持CSS3伪类和属性选择器
    <!--[if lte IE 8]>
            <script src="scripts/selectivizr.js"></script>
        <![endif]-->

    ② 让IE9以下的浏览器支持Html5标签和媒体查询器(主要用于响应式网站开发)
    <!--[if lt IE 9]>
           <script src="scripts/css3-mediaqueries.js"></script>
           <script src="scripts/html5shiv.js"></script>

       <![endif]-->

    上面两步的具体代码:
    <!DOCTYPE html>
    <html xmlns="http://www.w3.org/1999/xhtml" id="test">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <!--禁止浏览器缩放-->
        <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
        <meta content="application/xhtml+xml;charset=UTF-8" http-equiv="Content-Type" />
        <!--清除浏览器缓存-->
        <meta http-equiv="pragma" content="no-cache">
        <meta http-equiv="Cache-Control" content="no-cache, must-revalidate">
        <meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT">
        <!--iPhone 手机上设置手机号码不被显示为拨号链接)-->
        <meta content="telephone=no, address=no" name="format-detection" />
        <!--IOS私有属性,可以添加到主屏幕-->
        <meta name="apple-mobile-web-app-capable" content="yes" />
        <!--屏幕顶部条的颜色-->
        <meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />

        <title>手机webApp</title>
        <!--让IE8,IE9,支持Html5和Css3-->
        <!--[if lte IE 8]>
            <script src="scripts/selectivizr.js"></script>
        <![endif]-->
        <!--[if lt IE 9]>
            <script src="scripts/css3-mediaqueries.js"></script>
            <script src="scripts/html5shiv.js"></script>
        <![endif]-->

    </head>

    这样我们就部署好一个简单WebApp头部了

    第三步:添加重置样式(reset.css)和解决手机WebApp字体和图片等标签问题
    ① 添加重置样式,主要为了解决浏览器部分标签在各大浏览器上显示的一致问题(reset.css)
    html, body, div, span, applet, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, a, abbr, acronym, address, big, cite, code, del, dfn, em, font, img, ins, kbd, q, s, samp, small, strike, strong, sub, sup, tt, var, b, u, i, center, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td { margin: 0; padding: 0; border: 0; outline: 0; font-size: 100%; vertical-align: baseline; background: transparent; }
    body { line-height: 1; }
    ol, ul { list-style: none; }
    blockquote, q { quotes: none; }
    blockquote:before, blockquote:after, q:before, q:after { content: ''; content: none; }
    /* remember to define focus styles! */
    :focus { outline: 0; }
    /* remember to highlight inserts somehow! */
    ins { text-decoration: none; }
    del { text-decoration: line-through; }
    /* tables still need 'cellspacing="0"' in the markup */
    table { border-collapse: collapse; border-spacing: 0; }

    ② 设置手机字体和部分标签样式问题(common.css)
    /* 禁用iPhone中Safari的字号自动调整 */
    html { -webkit-text-size-adjust: none; }
    /* 设置HTML5元素为块 */
    article, aside, details, figcaption, figure, footer, header, hgroup, menu, nav, section { display: block; }
    /* 设置图片视频等自适应调整 */
    img { max-width: 100%; height: auto; width: auto9; /* ie8 */ }

    .video embed, .video object, .video iframe { width: 100%; height: auto; }

    通过上面三个步骤,一个基本的手机WebApp框架就构建好了

    但是还缺点什么呢?那就是让手机支持触摸事件!在这里我推荐一个js插件,hammer.js
    hammer.js是一款开源的移动端脚本框架,他可以完美的实现在移端开发的大多数事件,如:点击、滑动、拖动、多点触控等事件。不需要依赖任何其他的框架,并且整个框架非常小,在使用时非常简单。并且hammer.js的兼容性和拓展性非常好,hammer.js主要针对触屏的6大事件进行监听。如下图所示:

    第四步:为手机添加触屏插件:hammer.js
    <script type="text/javascript" src="scripts/hammer.js"></script>


    这样一个稍微完整的WebApp开发框架就搭配好了,详细代码:

    HTML代码
    <!DOCTYPE html>
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <!--禁止浏览器缩放-->
        <meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no">
        <meta content="application/xhtml+xml;charset=UTF-8" http-equiv="Content-Type" />
        <!--清除浏览器缓存-->
        <meta http-equiv="pragma" content="no-cache">
        <meta http-equiv="Cache-Control" content="no-cache, must-revalidate">
        <meta http-equiv="expires" content="Wed, 26 Feb 1997 08:21:57 GMT">
        <!--iPhone 手机上设置手机号码不被显示为拨号链接)-->
        <meta content="telephone=no, address=no" name="format-detection" />
        <!--IOS私有属性,可以添加到主屏幕-->
        <meta name="apple-mobile-web-app-capable" content="yes" />
        <!--屏幕顶部条的颜色-->
        <meta name="apple-mobile-web-app-status-bar-style" content="black-translucent" />

        <title>手机webApp</title>
        <!-- 重置样式 -->
        <link type="text/css" href="css/reset.css" rel="stylesheet" />
        <!-- 主样式 -->
        <link type="text/css" href="css/common.css" rel="stylesheet" />
        <!-- Jquery库 -->
        <script type="text/javascript" src="scripts/jquery-1.11.1.min.js"></script>
        <!-- 手机触摸 -->
        <script type="text/javascript" src="scripts/hammer.js"></script>
        <!--让IE8,IE9,支持Html5和Css3-->
        <!--[if lte IE 8]>
            <script src="scripts/selectivizr.js"></script>
        <![endif]-->
        <!--[if lt IE 9]>
            <script src="scripts/css3-mediaqueries.js"></script>
            <script src="scripts/html5shiv.js"></script>
        <![endif]-->
    </head>
    <body>
