一、通过uni.showActionSheet实现底部选择

效果

 代码

<template><view><button @click="showActionsheet">点击打开弹窗</button></view>
</template><script>
export default {methods: {showActionsheet() {uni.showActionSheet({itemList: ['选项1', '选项2', '选项3'],success: (res) => {console.log('选择了第' + (res.tapIndex + 1) + '个选项');},fail: (err) => {console.log('弹窗取消');}});}}
};
</script>

二、自定义底部弹出窗

 代码

<template><view><button @click="togglePopup">点击打开弹窗</button><view v-if="showPopup" class="popup"><view class="content"><view class="line1"><view>料号编辑</view></view><view class="line2"><view>料号：</view><view>料号名称：</view><view>规格型号：</view><view>单位：</view></view></view><view class="btn-group"><view class="btn_position"><view class="cancel" @click="cancel">取消</view><view class="submit" @click="submit">提交</view></view></view></view><view v-if="showPopup" class="mask" @click="togglePopup"></view></view>
