uniapp jumps directly to http

uniapp is a multi-terminal development framework that integrates Vue.js and WeChat applet development frameworks. It allows us to write code using Vue.js syntax and run it on multiple platforms. The method of directly jumping http links in uniapp is very simple. Let’s take a closer look below.

1. What is uniapp?

As a professional multi-terminal development framework, uniapp solves all the problems of developing Android and iOS applications separately. Instead, it allows developers to write applications and run them on multiple platforms at the same time. At the same time, uniapp's code can also be shared between different platforms, which makes the development process easier and faster.

2. How to jump directly to http in uniapp

If we want to jump directly to the http link in uniapp, then we need to get the current web-view Component, jump through the built-in navigateTo method of the web-view component.

We can define a button in the template to trigger the jump operation.

<template>
  <div>
    <button @click="jumpToUrl">跳转到百度</button>
  </div>
</template>

Then in the script script, we need to define a jumpToUrl function to jump to the specified http link.

<script>
  export default {
    data () {
      return {
        url: 'https://www.baidu.com'
      }
    },
    methods: {
      jumpToUrl () {
        uni.navigateTo({
          url: '/pages/webview/webview?url=' + encodeURIComponent(this.url)
        })
      }
    }
  }
</script>

In the above code, we first define a url variable to save the link to be jumped. Then in the jumpToUrl function, we use the uni.navigateTo method to jump, and pass the link to be jumped as a parameter to the webview component.

3. Implementing the web-view component

In the above code, we use the webview component to jump to the http link. Therefore, we need to create a new webview folder in the pages directory and create a webview.vue file to implement this component.

<template>
  <div class="webview">
    <web-view :src="url" :title="title" @message="receiveMessage" />
  </div>
</template>

<script>
  export default {
    data () {
      return {
        url: '',
        title: ''
      }
    },
    onLoad (options) {
      this.url = decodeURIComponent(options.url)
      this.title = options.title || ''
    },
    methods: {
      receiveMessage (e) {
        console.log(e.detail)
      },
    }
  }
</script>

In the above code, we first use the web-view tag in the template to display the webview component. Then in the script, we define a data object to save the link and title to be displayed. At the same time, we also defined a receiveMessage method to receive messages from the webview component.

4. Summary

Through the above operations, we have successfully implemented the method of directly jumping http links in uniapp. First, we define a button in the template to trigger the jump operation. Then in the script, we define the jump operation and jump to the webview component through uni.navigateTo. Finally, we also implemented a webview component to display the link to jump. In this way, we can jump directly to the http link in uniapp.
