swiper

（涉及到swiper.min.js，swiper.min.css，记得导入这两个文件。）
两种样式：

1）标题 + 页数。

2）标题。

第一种：标题+页数。

<div class="swiper-container" id="swiper-container">
    <div class="swiper-wrapper" >
        <div class="swiper-slide" data-hash="slide2"><img src="picA.jpg"/>
            <div class="title">第一张图</div>
            <div>
            	<span class="swiper-title"></span>
            	<span class="swiper-now"></span>
            </div>
        </div>
        <div class="swiper-slide" data-hash="slide2"><img src="picA.jpg"/><div class="title">第二张图</div>
            <div>
            	<span class="swiper-title"></span>
            	<span class="swiper-now"></span>
            </div>
        </div>
        <div class="swiper-slide" data-hash="slide2"><img src="picA.jpg"/><div class="title">第三张图</div>
            <div>
            	<span class="swiper-title"></span>
            	<span class="swiper-now"></span>
            </div>
        </div>
        <div class="swiper-slide" data-hash="slide2"><img src="picA.jpg"/><div class="title">第四张图</div>

        </div>
    </div>
    <!-- <div class="swiper-pagination" id="swiper-pagination"></div> -->
   
    
</div>

.swiper-slide {
    width: 100%;
    height: 200px;
  /*  background: #999 url(../image/log.png) center center no-repeat;
    background-size: 200px auto;*/
}

.swiper-slide  img {
    width:100%;
    height: 100%;
}

.swiper-pagination {
    position: absolute;
    bottom: 10px;
}
.swiper-title{
	line-height: 30px;
    position: absolute;

	/*z-index: 2;*/

}
.title{
	font-size: 13px;
	font-weight: 600;
	width: 80%;
	height: 30px;
	line-height: 36px;

}
.swiper-now{
	position: absolute;
	bottom: 6px;

	color: #4b9edc;
}

var mySwiper = new Swiper('.swiper-container',{
    pagination: '.swiper-pagination',
    loop:true,
    grabCursor: true,
    paginationClickable: true,
    autoplay: 3000
});

var now = document.querySelectorAll(".swiper-now"); 
var imgs = document.querySelectorAll(".swiper-title");

var count = imgs.length-2;
for(var i=0;i<imgs.length;i++){
	imgs[i].innerText = '/'+count;
}

now[0].innerText = '1';

for(var i=1;i<imgs.length-1;i++){
    now[i].innerText = i;
}
now[imgs.length-1].innerText = '1';

第二种：标题。

        <div class="swiper-slide" data-hash="slide2"><img src="picA.jpg"/><div class="swiper-title">第四页</div></div>
        <div class="swiper-slide" data-hash="slide2"><img src="picA.jpg"/><div class="swiper-title">第五页</div></div>
        
    </div>
    <!-- <div class="swiper-pagination" id="swiper-pagination"></div> -->
<div id="page"><span id="now">1</span><span id="all"></span></div>
   
    
</div>

.swiper-slide {

}
#page{

	right: 20px;
	bottom: 0;
	background: red;
}
#page span{ display: block;color: #fff;float: left; }

var mySwiper = new Swiper('.swiper-container',{
    pagination: '.swiper-pagination',
    loop:true,
    grabCursor: true,
