With the popularity of mobile web applications, Webview pop-up windows have become one of the common requirements in mobile web application development. As an excellent cross-platform development framework, Uniapp also provides Webview-related components and APIs, allowing developers to easily implement the function of Webview pop-up windows.

This article will focus on the method and specific steps of how to use Webview to implement pop-up windows in Uniapp.

Create Webview component

First, create a Webview component in Uniapp. In Uniapp, we can use the webview component to display web pages.

Code example:

<template>
  <view class="container">
    <web-view :src="url" :style="webViewStyle" @message="onMessage"></web-view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      webViewStyle: {
        height: `${uni.upx2px(500)}px`
      },
      url: 'https://www.example.com'
    }
  },
  methods: {
    onMessage(e) {
      //  接收来自webview组件发来的数据
      console.log(e.detail.data)
    }
  }
}
</script>

Introduce the Webview component into the pop-up window component

Next, we need to introduce the Webview component into the pop-up window component. In this case, we will create a bottom pop-up component that will be displayed when the user clicks on other components.

Code example:

<template>
  <view>
    <!-- 遮罩 -->
    <view class="mask" v-show="visible" @click="onClose"></view>

    <!-- 底部弹窗 -->
    <view class="popup" :class="{ show: visible }">
      <webview :src="url" :style="webViewStyle"></webview>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      visible: false, // 是否展示底部弹窗
      webViewStyle: {
        height: `${uni.upx2px(500)}px`
      },
      url: 'https://www.example.com'
    }
  },
  methods: {
    // 打开底部弹窗
    open() {
      this.visible = true;
    },
    // 关闭底部弹窗
    onClose() {
      this.visible = false;
    }
  }
}
</script>

<style>
.popup {
  position: fixed;
  bottom: 0;
  width: 100%;
  height: auto;
  background-color: #fff;
  z-index: 1000;
  transform: translateY(100%);
  transition: transform .3s;
}

.popup.show {
  transform: translateY(0);
}

.mask {
  position: fixed;
  top: 0;
  left: 0;
  width: 100%;
  height: 100%;
  opacity: .6;
  background-color: #000;
  z-index: 999;
  transition: opacity .3s;
}

.mask.show {
  opacity: 1;
}
</style>

Trigger pop-up window

Finally, we need to listen to click events in other components, and when the user clicks, call the pop-up window The open method of the window component is used to display the pop-up window.

Code example:

<template>
  <view>
    <view class="button" @click="showPopup">显示弹窗</view>
    <popup ref="popup"></popup>
  </view>
</template>

<script>
    import Popup from './components/popup'

    export default {
        components: {
            Popup
        },
        methods: {
            // 显示弹窗
            showPopup() {
                this.$refs.popup.open()
            }
        }
    }
</script>
