前言

因为uni自带的picker无法自定义样式,所以自定义封装了滚动选择器

注意

改封装基于Uview组件的popup弹出层，不想用uview的可自行写popup，或者使用uniapp的扩展组件自行调整

先看效果：

标题，关闭按钮，确认按钮可以自定义修改组件，调整方便

父组件中使用

	import mypopup  from '../../components/mypopup.vue'
	export default {
		components:{
			mypopup
		},

	<mypopup label="label"
        :isShow="isShowTeamNumber" 
	    :dataList="teamList"
	    @getVal="getVal" 
	    popupTitle="团队规模"
	    @getIsShow="getIsShow">
    </mypopup>


			getVal(e) {
				console.log(e,'123')
				this.teamValue = e.label;   
			},
			getIsShow(e) {
				this.isShowTeamNumber = e
			},
