bootstrap自帶的響應(yīng)式導(dǎo)航欄是向下滑動(dòng)的，有時(shí)滿足不了個(gè)性化的需求，需要做一個(gè)類似于android drawerLayout 側(cè)滑的菜單，這就是我要實(shí)現(xiàn)的bootstrap自定義側(cè)滑菜單，參考了很多官網(wǎng)的側(cè)滑，實(shí)現(xiàn)方法各有不同，優(yōu)缺點(diǎn)也十分明顯，有的官網(wǎng)首頁(yè)為了僅僅實(shí)現(xiàn)一個(gè)側(cè)滑的效果，用了owl.carousel滑屏的插件，個(gè)人覺得小題大做了。這個(gè)bootstrap側(cè)滑菜單更專業(yè)的名字叫做手機(jī)導(dǎo)航欄。我也比較這個(gè)名字，更符合bootstrap的特性。所以我這篇文章介紹的更容易的一種做法，新手更容易接受。
bootstrap側(cè)邊導(dǎo)航欄實(shí)現(xiàn)原理
1.側(cè)滑欄使用定位fixed
2.使用bootstrap響應(yīng)式使用工具類 visible-sm visible-xs hidden-xs hidden-sm等對(duì)不同屏幕適配
3.側(cè)滑欄的側(cè)滑效果不使用jquery方法來實(shí)現(xiàn)，使用的是css3 transforms屬性進(jìn)行div的移動(dòng)，側(cè)滑的動(dòng)畫效果使用的是css屬性transition
4.缺點(diǎn)：使用兩套菜單，一套是pc端屏幕顯示的菜單，一套是移動(dòng)端顯示的手機(jī)導(dǎo)航菜單，這個(gè)缺點(diǎn)比較明顯，生成無(wú)關(guān)的標(biāo)簽，優(yōu)點(diǎn)代碼少，簡(jiǎn)單容易接受

一個(gè)導(dǎo)航欄的布局，用了兩個(gè)導(dǎo)航菜單，一個(gè)是pc端的，一個(gè)是手機(jī)端，利用bootstrap響應(yīng)式使用工具類visible-xs visible-sm來實(shí)現(xiàn)pc端隱藏切換按鈕； visible-lg visible-md 實(shí)現(xiàn)了pc端顯示導(dǎo)航欄；visible-xs visible-sm實(shí)現(xiàn)手機(jī)端顯示手機(jī)導(dǎo)航欄。

css實(shí)現(xiàn)布局和側(cè)滑效果（側(cè)滑的關(guān)鍵css3屬性transform、transition）
代碼不多，僅僅10行
* {margin:0;padding:0;} #mobile-menu {position:fixed;top:0;left:0;width:220px;height:100%;background-color:#373737;z-index:9999;} a:hover ,a:focus{text-decoration:none} .mobile-nav ul li a {color:gray;display:block;padding:1em 5%; border-top:1px solid #4f4f4f;border-bottom:1px solid #292929;transition:all 0.2s ease-out;cursor:pointer;#mobile-menu {position:fixed;top:0;left:0;width:220px;height:100%;background-color:#373737;z-index:9999;transition:all 0.3s ease-in;}} .mobile-nav ul li a:hover {background-color: #23A1F6;color: #ffffff;} .show-nav {transform:translateX(0);} .hide-nav {transform:translateX(-220px);} /*側(cè)滑關(guān)鍵*/ .mobile-nav-taggle {height:35px;line-height:35px;width:35px;background-color:#23A1F6;color:#ffffff;display:inline-block;text-align:center;cursor:pointer} .nav.avbar-inverse{position:relative;} .nav-btn {position:absolute;right:20px;top:20px;}要值得注意的是css3的兩個(gè)屬性：
transform：旋轉(zhuǎn)div，支持元素2D或3D旋轉(zhuǎn)，屬性值translateX（X）就是在X軸上移動(dòng)Xpx的距離
http://www.w3school.com.cn/cssref/pr_transform.asp
而側(cè)滑的動(dòng)畫效果是使用transition屬性，設(shè)置屬性的過渡動(dòng)畫的效果，語(yǔ)法
transition: property duration timing-function delay;
http://www.w3school.com.cn/cssref/pr_transition.asp
單擊事件切換側(cè)滑
$("#mobile-nav-taggle").click(function () { var mobileMenu = $("#mobile-menu"); if (mobileMenu.hasClass("show-nav")) { setTimeout(function () { mobileMenu.addClass("hide-nav").removeClass("show-nav"); }, 100) } else { setTimeout(function (){ mobileMenu.addClass("show-nav").removeClass("hide-nav"); }, 100) } })總結(jié)
不推薦用兩個(gè)菜單導(dǎo)航欄，缺點(diǎn)很明顯，為了實(shí)現(xiàn)效果而已，不要介意，其實(shí)用一個(gè)菜單導(dǎo)航欄也是可以實(shí)現(xiàn)，試試media 完全可以實(shí)現(xiàn)。
