uni-app实现点击弹窗输⼊⽂本的交互操作（3）（组件化）uni-app实现点击弹窗输⼊⽂本
写成组件
前⾯的学习：
组件形式：
主页⾯：
<view class="login">
<view class="login-btn" @click="show">
<prompt ref="prompt" @onConfirm="onConfirm" @onCancel="onCancel" title="提⽰"></prompt>
</view>
</view>
import prompt from '../prompt/prompt.vue';
data() {
return {
};
},
components: {
prompt,
},
/*
引⼊弹窗prompt插件
*/
show: function() {
this.$refs.prompt.isHidden = !this.$refs.prompt.isHidden;
},
组件：prompt.vue  与 prompt.css
<view class="prompt-box" v-if="isHidden" @click.stop="!show">
<view class="prompt-content contentFontColor">
<view class="prompt-title">修改库存</view>
<view class="container">
