使用swiper制作轮播图的时候，轮播的图片大概率是使用ajax从后台获取到的。每一次获取图片都要重新初始化swiper.
$.ajax({
type: "get",
url: "update/",
dataType: "json",
success: function(data) {
data = JSON.parse(data);
console.log(data);
for(var i = 0; i < data.length; i++) {
$('.banner .swiper-wrapper').append($('<div class="swiper-slide"><img src=' + data.path + '/></div>'))
};
var swiper = new Swiper('.swiper-container', {
loop: true,
centeredSlides: true,
autoplay: {
delay: 2500,
},
pagination: {
el: '.swiper-pagination',
clickable: true,
},
});
},
error: function() {
}
});
