What should I do if dynamic loading of data always fails when sliding?

success:function(result){
var resultdata =eval("("+result+")");
if(resultdata.status == 1){
	var dataList = resultdata.data;
	currentPage = resultdata.currentPage;
	pageCount = resultdata.pageCount;
	var html = "";
	if(pageCount == 0){
		html ='<p class="noCollect">' + resultdata.msg + '</p>';
	}else{
		for(var i in dataList){
			var data = dataList[i];
			html += '<p class="swiper-container artistp">'
			+ '<p class="swiper-wrapper">'
			+ '<p class="swiper-slide workp">'
			+ '<p class="app_inlineBlock workPic">'
			+ '<img class="picImg" src="&#39;+ data.artistAvatar +&#39;" />'
			+ '</p>'+'<p class="app_inlineBlock workInfo">'
			+ '<p class="artistName">' + data.artistName + '</p>'
			+ '<p class="workName">' + data.artworkName + '</p>'
			+ '<p class="workValue">'+ data.typeName +'/'+ data.width + '*' + data.height +'/' +data.createYear + '</p>'
			+ '</p><p class="app_inlineBlockRight workPrice">'
			+ '<p class="price">￥'+ data.marketPrice +'</p></p></p>'
			+ '<p class="swiper-slide delBtn">删除</p></p></p>';
		}
		
	}
	$("#list").append(html);
	//swiper初始化 
	var swiper = new Swiper('.swiper-container', {
		pagination: '.swiper-pagination',
		slidesPerView: 'auto',
		paginationClickable: true,
		spaceBetween: 0
	});
}

swiper1 = new Swiper('.swiper-container', { 
 initialSlide :0, 
 observer:true,//修改swiper自己或子元素时，自动初始化swiper 
 observeParents:true//修改swiper的父元素时，自动初始化swiper 
});
