关于OWL-carousel插件在ajax调用后需要重新实例化问题(页面无轮播效果)

维护公司老项目，发现问题，记录一下~ 

1.产生原因

owl 已经实例已经存在,在ajax请求成功后并更改完页面数据后, 但是没有销毁之前实例,并重新生成新的实例,导致没有owl插件没有轮播效果.

2.解决方案

html：

<div class="owl-slider ps-carousel" data-owl-auto="true" data-owl-loop="true" data-owl-speed="7500" data-owl-gap="30"data-owl-nav="true" data-owl-item="3" data-owl-item-xs="1" data-owl-item-sm="2" data-owl-item-md="3"data-owl-item-lg="3" data-owl-duration="1000" data-owl-mousedrag="false" id="carousel-featured-properties"><div class="ps-project ps-project--grid"><div class="ps-project__thumbnail"><div class="ps-project__image"><img src="../img/property/1.jpg" alt="" id="img0" /></div><aclass="ps-project__overlay" id="detail0"></a><div class="ps-project__actions"><a href="javascript:void(0)" style="float: right"><iclass="lnil lnil-star-fill active"></i></a></div></div><div class="ps-project__content"><h4 class="ps-project__name"><a id="name0">房屋名称111</a></h4><p class="ps-project__address" id="address0">上海市,闵行区,浦秀路</p><p class="ps-project__price"><strong id="price0">¥2,0000/月</strong></p><div class="ps-project__meta"><figure><figcaption>房产经济人</figcaption><p id="agent0">张三</p></figure><figure><figcaption>状态</figcaption><p id="state0">出售</p></figure><figure><figcaption>时间</figcaption><p id="build0">7/4/2021</p></figure></div><div class="ps-project__services"><p><span id="arce0"><i class="lnil lnil-size"></i>250 ㎡</span></p><p><span id="bedroom0"><i class="lnil lnil-hospital-bed"></i>3 卧室</span></p><p><span id="bathroom0"><i class="icon icon-bathtub"></i>2 浴室</span></p></div></div></div><div class="ps-project ps-project--grid">//第二个</div><div class="ps-project ps-project--grid">//第三个</div><div class="ps-project ps-project--grid">//第四个</div></div>

js:

success: function (result) {
// alert("查找成功");
//console.log(result)
var allHouse = result.data;
$("#carousel-featured-properties").trigger("destroy.owl.carousel")
$("#carousel-featured-properties").html("");// $("#testId").html('<div class="owl-slider ps-carousel" data-owl-auto="true" data-owl-loop="true"data-owl-speed="7500" data-owl-gap="30" data-owl-nav="true" data-owl-item="4" data-owl-item-xs="1"data-owl-item-sm="2" data-owl-item-md="3" data-owl-item-lg="3" data-owl-duration="1000" data-owl-mousedrag="false"id="carousel-featured-properties"></div>');
$(allHouse).each(function (index,house1){
var house = house1.bHouse;
var image = house1.image;
var agents = house1.agents;// 第二种写法,但是无轮播效果
var div = ' <div class="ps-project ps-project--grid">\n' +' <div class="ps-project__thumbnail">\n' +' <div class="ps-project__image"><img src="'+image[0].imageUrl+'" alt="" id="img0" /></div><aclass="ps-project__overlay" id="detail0"></a>\n' +' <div class="ps-project__actions"><a href="javascript:void(0)" style="float: right"><iclass="lnil lnil-star-fill active"></i></a></div>\n' +' </div>\n' +' <div class="ps-project__content">\n' +' <h4 class="ps-project__name"><a id="name0">'+house.houseName+'</a></h4>\n' +' <p class="ps-project__address" id="address0">'+house.address+'</p>\n' +' </p>\n' +' <div class="ps-project__meta">\n' +' <figure>\n' +' <figcaption>房产经济人</figcaption>\n' +' <p id="agent0">'+agents.name+'</p>\n' +' </figure>\n' +' <figure>\n' +' <figcaption>状态</figcaption>\n' +' <p id="state0">'+house.state+'</p>\n' +' </figure>\n' +' <figure>\n' +' <figcaption>时间</figcaption>\n' +' <p id="build0">'+house.buildTime+'</p>\n' +' </figure>\n' +' </div>\n' +' <div class="ps-project__services">\n' +' <p><span id="arce0"><i class="lnil lnil-size"></i>'+house.area+' ㎡</span></p>\n' +' <p><span id="bedroom0"><i class="lnil lnil-hospital-bed"></i>'+house.bedroom+' 卧室</span></p>\n' +' <p><span id="bathroom0"><i class="icon icon-bathtub"></i>'+house.bathroom+' 浴室</span></p>\n' +' </div>\n' +' </div>\n' +' </div>';$(".owl-slider").append(div);});$(".owl-slider").owlCarousel({
items: 3
});},
error: function (){
alert("查询失败");
}

重点:

 先销毁实例 再插入数据 再生成实例

//销毁实例代码
$("#carousel-featured-properties").trigger("destroy.owl.carousel")
//生成实例代码
$(".owl-slider").owlCarousel({});
