【vue 组件 mint-ui】 看了一下源码,给轮播图Swiper封装自定义跳转的函数

mint-ui 自身提供了前一页，后一页的function,这里由于项目需求,点击任意tab都可跳转到相应的图片,所以自己封装了一个function:switchCar。

查看项目请到(https://github.com/Rise-Devin/FullStack-Product-Transport-User)

Usage

import Mint from ‘mint-ui’;

import { Swipe, SwipeItem } from ‘mint-ui’;

Vue.component(Swipe.name, Swipe);

Vue.component(SwipeItem.name, SwipeItem);

html

switchCat 为点击tab切换轮播图事件（我封装的自定义跳转事件）,

front为 mint-ui提供的前一页的事件

back为 mint-ui提供的后一页的事件

mt-swipe 、mt-swipe-item为 mint-ui 提供的轮播图组件

<ul >
<li @click="switchCar(index)" :class="carIndex==index?'active':''" v-for="(car,index) in carConfig">{{car.name}}</li>
<i class="border" ref="nav_border"></i>
</ul>
<div>
<i @click.stop="front()" class="fa fa-angle-left fa-btn banner-left" aria-hidden="true"></i>
<i @click.stop="back()" class="fa fa-angle-right fa-btn banner-right" aria-hidden="true"></i>
<ul ref="carBox">
<mt-swipe :show-indicators="false"  ref="mtSwipe" @change="handleChange" :auto="0">
<mt-swipe-item ref="mtItem" v-for="car in carConfig" :key="car.name"><img :src="car.img_src"/></mt-swipe-item>
</mt-swipe>
<p class="car_title">{{carConfig[carIndex].name}} 起步价: ￥{{curCarConfig.price}}</p>
</ul>
</div>

js

front(){   //前一页
this.$refs.mtSwipe.prev();
},
back(){    //后一页
this.$refs.mtSwipe.next();
},
handleChange(index){    //跳转之后获取当前的下标
this.carIndex = index;
},
switchCar(index)    //自定义跳转，只需要传图片的下标即可
{
if(index==this.carIndex)
{
console.log('break off');
return;
}

var callback = () => {
if (index !== undefined) {
var newPage = this.$refs.mtItem[index].$el;
removeClass(curPage.$el, 'is-active');
addClass(newPage, 'is-active');

this.$refs.mtSwipe.index = index;
}
if (this.$refs.mtSwipe.isDone) {
this.$refs.mtSwipe.end();
}

if (prevPage) {
prevPage.$el.style.display = '';
}

if (nextPage) {
nextPage.$el.style.display = '';
}
};

if(index>this.carIndex)
{
var curPage = this.$refs.mtItem[this.carIndex];
var nextPage = this.$refs.mtItem[index];
var pageWidth= this.$refs.mtItem[0].$el.clientWidth;
if (nextPage) {
nextPage.$el.style.display = 'block';
this.$refs.mtSwipe.translate(nextPage.$el, pageWidth);
}
console.log(this.$refs.mtSwipe.isDone);
this.$refs.mtSwipe.isDone = true;
this.$refs.mtSwipe.before(curPage.$el);

this.$refs.mtSwipe.translate(curPage.$el, -pageWidth, 300, callback);
if (nextPage) {
var self =this;
var timer = setTimeout(function(){
self.$refs.mtSwipe.translate(nextPage.$el, 0, 300);
clearTimeout(timer);
},50)

}
}
else if(index<this.carIndex)
{
var curPage = this.$refs.mtItem[this.carIndex];
var prevPage = this.$refs.mtItem[index];
var pageWidth= this.$refs.mtItem[0].$el.clientWidth;

if (prevPage) {
prevPage.$el.style.display = 'block';
this.$refs.mtSwipe.translate(prevPage.$el, -pageWidth);
}

this.$refs.mtSwipe.isDone = true;
this.$refs.mtSwipe.before(curPage.$el);
this.$refs.mtSwipe.translate(curPage.$el, pageWidth, 300, callback);
if (prevPage) {
this.$refs.mtSwipe.translate(prevPage.$el, 0, 300);
}
}
},
