轮播图组件更加完善版

依然是基于微博语法开发，使用时请注意标签替换

优化了滑动的效果，默认的索引，滑动距离等，

使用方式和以前一样没变，主要修改了组件内部

<template><wbx-view class="" style="width: 100vw;height: 70vh;"><wbx-view style="margin-top: 100px; margin-left: 100px;margin-bottom: 20px;"><WBXswiper  @change="gaibian" :vertical="false"  :current="5" indicatorActiveColor="#fff" indicatorColor="#c0c0c0" :originalData="items"   style="width: 200px;height: 200px;border-radius: 20px;"><template slot="swiperItem" slot-scope="scope"><wbx-image :src="scope.item.src" mode="scaleToFill" style="width:200px; height: 200px;" /></template></WBXswiper></wbx-view></wbx-view>
</template><script>
/*** @type WBXAppOption*/
import WBXswiper from "../../commpents/WBXswiper/index.vue";
const pageOptions = {data() {return {items: [{src: 'res/001.jpg',txt:222222},{src: 'res/001.jpg',txt:222222},{src: 'res/001.jpg',txt:222222},{src: 'res/001.jpg',txt:222222},{src: 'res/001.jpg',txt:222222}],current:0}},computed:{},methods: {gaibian(e){},add(index){this.current=index}},components: {WBXswiper,},wbox: {onLoad() { },onShow() {// 页面显示/切入前台时触发},onHide() {// 页面隐藏时触发},onUnload() {// 页面退出时触发},},mounted() { },
};
export default pageOptions;
</script><style></style>

已下是组件内部
