近期在網(wǎng)站開發(fā)過程中遇到了一個需要組合輪播圖片的頁面，頁面布局如下：
 

先來講一下具體功能是：點擊左側(cè)“公司資質(zhì)”或者“產(chǎn)品證書”，右邊切換到相應(yīng)的輪播模塊。中間的圖片可以左右拖動切換，同時帶動右邊名稱的選中狀態(tài)切換，右邊的名稱點擊能切換中間的圖片，使對應(yīng)的圖片能居中放大顯示，也是就是中間的當(dāng)前圖片與右邊的名稱是一一對應(yīng)的。
 
下面再來講一下頁面布局結(jié)構(gòu)如下：
 
 
 
 
除了以上的html代碼外，實現(xiàn)上述的功能還需要下面的js代碼，這些代碼看起來雖然比較復(fù)雜，但使用方法卻是比較傻瓜式，直接粘貼到頁面上就可以用，所以看不懂以下的JS代碼也沒關(guān)系，但對于一些關(guān)鍵的類名，例如上面的html代碼寫的hon_con_box1,hon_name_box1,swip_tab2等類名還是要跟JS代碼對應(yīng)起來，不然就實現(xiàn)不了多組合輪播功能，JS代碼如下：
 
if($("body").hasClass("swip_box")){
//資質(zhì)榮譽(yù)
if ($(".imgbox2").hasClass("swip_tab2")){
var sib,sib2,sib3;
if (wind_w > 780){
sib = "vertical";
sib2 = 4;
sib3 = false;
} else {
sib = "horizontal";
sib2 = "auto";
sib3 = true;
}

以上功能是基于 swiper.js 插件最新版本實現(xiàn)的。由于swiper 插件對ie的兼容性不是很到位，所以這里的輪播不兼容ie 低版本，也就是IE8以下的版本均不支持該效果，不過現(xiàn)在用IE8以下的瀏覽器比較少了，除了window xp系統(tǒng)和少部分的win 7系統(tǒng)外。
