How to implement prompt box component in uniapp

UniApp is a cross-platform application development framework based on the Vue framework. It allows us to use one set of code to develop applications for multiple different platforms at the same time. In UniApp, we often need to use prompt box components to display some important information or interact with users. This article will introduce how to implement the prompt box component in UniApp and provide code examples.

In UniApp, we can use the Uni-Modal component to implement the prompt box function. The Uni-Modal component is a pop-up layer component built into UniApp, which can be used to display various types of prompt information.

First, we need to introduce the Uni-Modal component into the page where the prompt box needs to be used:

<template>
  <view>
    <!-- 其他页面内容 -->
    
    <!-- 提示框组件 -->
    <uni-modal
      ref="modal"
      :show="showModal"
      :title="modalTitle"
      :content="modalContent"
      @click-overlay="hideModal"
      @click-confirm="confirmModal"
      @click-cancel="hideModal"
    ></uni-modal>
  </view>
</template>

Then, define the relevant data and methods in the Vue instance of the page:

<script>
export default {
  data() {
    return {
      showModal: false, // 是否显示提示框
      modalTitle: '', // 提示框标题
      modalContent: '', // 提示框内容
    }
  },
  methods: {
    // 显示提示框
    showModal(title, content) {
      this.modalTitle = title
      this.modalContent = content
      this.showModal = true
    },
    // 隐藏提示框
    hideModal() {
      this.showModal = false
    },
    // 确认按钮点击事件
    confirmModal() {
      // 处理确认操作逻辑
      
      // 隐藏提示框
      this.hideModal()
    }
  }
}
</script>

Next, we can call the showModal() method to display the prompt box when needed, and just pass in the corresponding title and content:

// 显示一个简单的提示框
this.showModal('提示', '这是一个简单的提示框')

// 显示一个带有确认按钮的提示框
this.showModal('确认提示', '确定要进行删除操作吗？')

// 显示一个带有取消按钮和确认按钮的提示框
this.showModal('操作确认', '确定要提交表单吗？')

The above is in UniApp Basic steps and code examples for implementing the prompt box component. By introducing and using the Uni-Modal component, we can easily implement various types of prompt boxes in UniApp. According to actual needs, we can also customize the style and function of the prompt box to adapt to different business scenarios.
