移动端左侧导航的实现

一、实现效果

主页：

点击导航键：

二、实现方案

0x1 CSS3+javascript方案

1、实现思路

利用css3的transform变换
translate(x,y)，translatex() translatey()
transition过渡

<’ transition-property ‘>：检索或设置对象中的参与过渡的属性
<’ transition-duration ‘>：检索或设置对象过渡的持续时间
<’ transition-timing-function ‘>：检索或设置对象中过渡的动画类型
- linear：线性过渡。
  ease：平滑过渡。
  ease-in：由慢到快。
  ease-out：由快到慢。
  ease-in-out：由慢到快再到慢。
<’ transition-delay ‘>：检索或设置对象延迟过渡的时间
缩写：transition: all 0.2s ease-in-out;

2、网站主体

HTML部分

<body>
    <!-- 代码部分begin -->
    <section class="wraper-page">
        <header class="header">
            <span class="btn-slide-bar"></span>
            <h1 class="page-title">header</h1>
        </header>
        <p>请使用你的移动网页浏览本页面</p>
        <p>点击左上角按钮试试效果</p>
        <footer class="footer">footer</footer>
    </section>
    <section class="slide-bar">
        <ul>
            <li>首页</li>
            <li>菜单导航</li>
            <li>jQuery特效</li>
            <li>CSS3特效</li>
            <li>tab标签</li>
        </ul>
    </body>

    transition: all 0.2s ease-in-out;

}

* { -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; }

JS部分
DOMContentLoaded事件
DOMContentLoaded事件是在html document加载完成之后触发的。
不用等我们的样式、图片以及subframes等加载完毕。
相当于$(document).ready()
onload事件是页面上所有的DOM，样式表，脚本，图片，flash
都已经加载完成后触发。

<script>
    document.addEventListener("DOMContentLoaded", function(){
        (function(){
            var _btn  = document.querySelector(".btn-slide-bar"),
                _body = document.querySelector("body");
                _btn.onclick = function(){
                    _body.classList.toggle("active");
                }
        })(window)
    },false);
</script>

0x2 jquery方案

1、实现思路
运用经典的左侧固定，右侧自适应的布局方式

2、jQuery代码
采用面向对象的方式书写

var swiperFun = {
    init:function(){
        var _this = this ;
        //点击事件
        $('.btn-slide-bar').click(function(){
            if($(this).hasClass('active')){
                _this._swipeRight();
            }else{
                _this._swipeLeft();
            }
        });
    },
    _swipeLeft:function(){
        $('.slide-bar').animate({'width':'50%'},"50");
        $('.wraper-page').animate({'margin-left':'50%'},"50");
        $('.btn-slide-bar').addClass('active');
    },
    _swipeRight:function(){
        $('.slide-bar').animate({'width':'0'},"50");
        $('.wraper-page').animate({'margin-left':'0'},"50");
        $('.btn-slide-bar').removeClass('active');
    }
}
swiperFun.init();
