免费作图网站都有哪些营销的概念是什么

uniapp本身自带的actionsheet太丑，不够美观。闲着也是闲着，自己实现了一个类似的选择器。

支持功能：

1、左对齐

2、右对齐

3、居中

4、可加图标

下面贴出使用教程：

<template><view><action-sheet alignment="left" :showSheetView="showSheetView" :displayCheckedIcon="true" :optionsList="deseaseList" titleKey="name" iconKey="cover" @onSelected="onSelected"></action-sheet></view>
</template>

<script>import actionSheet from '@/components/zxp-uniActionSheet.vue'export default{data() {return {deseaseList: [],showSheetView:false};},components:{actionSheet},methods:{onSelected(row){/*这里必须将值置为false，否则无法唤起下一次的弹框显示*/this.showSheetView = false}}}
</script>

 组件实现代码：在你项目合适的目录中创建一个名为zxp-uniActionSheet.vue的组件文件，一般位于项目的components目录中，注意目录及页面中的引用位置！

或者直接通过hbuilderx引入到你的项目中！
