How to modify UniApp's native navigation style

With the development of mobile Internet and the popularity of smart devices, mobile application development has increasingly become one of the important tasks of programmers. As a cross-platform development tool, UniApp allows developers to write code once and complete application development in an environment where it can be run in multiple places. In this process, UniApp’s native navigation style is particularly important because it directly affects the user’s experience of using the application. Therefore, this article will introduce to you how to modify the native navigation style of UniApp.

UniApp’s native navigation

UniApp’s native navigation refers to the pages in the uni-app application. UniApp provides the need for customizing the navigation bar. Custom navigation bars can be divided into two types: custom background colors and custom buttons. In the UniApp framework based on Vue, we can implement a customized navigation bar by modifying the page configuration and APP.vue file.

Modify page configuration

In UniApp, we can customize the navigation bar by modifying the page configuration. The specific steps are as follows:

Step 1: Open the manifest.json file

Find the manifest.json file in the root directory of the UniApp project and open it.

Step 2: Modify the NavigationBarBackgroundColor attribute

In the "pages" attribute of the manifest.json file, find the json object of the page that needs to be customized, and then modify its NavigationBarBackgroundColor attribute. For example:

{
  "path": "pages/index/index",
  "style": {
    "navigationBarTitleText": "首页",
    "navigationBarBackgroundColor": "#ffffff", // 自定义背景色
    "navigationBarTextStyle": "black"
  }
}

Step 3: Recompile and run the project

After modifying the NavigationBarBackgroundColor property, you need to recompile the project and run it to see the modified navigation bar effect.

Modify the APP.vue file

If you need to implement a custom button navigation bar effect, you can do so by modifying the APP.vue file. The specific steps are as follows:

Step 1: Open the APP.vue file

Find the APP.vue file in the root directory of the UniApp project and open it.

Step 2: Modify the page navigation bar configuration

In the navigation bar configuration of APP.vue, we can customize the navigation bar through uniNavBar in the uni-ui component library. For example:

<template>
  <div>
    <uni-nav-bar
      title="自定义按钮样式"
      :back-text="&#39;返回&#39;"
      background-color="#ffffff"
      border-color="transparent"
      left-text="返回"
      left-arrow
      @click-left="back"
      @click-right="handleClickRight"
    />
  </div>
</template>

<script>
  import uniNavBar from '@/components/uni-nav-bar.vue'

  export default {
    components: {
      uniNavBar
    },
    methods: {
      handleClickRight() {
        console.log('点击右侧按钮')
      },
      back() {
        uni.navigateBack()
      }
    }
  }
</script>

Summary

Through the above two methods, we can achieve UniApp’s custom navigation bar style effect. When developing an application, we need to choose an appropriate navigation bar style to improve the user experience based on actual needs and the overall style of the application. At the same time, you also need to pay attention to the compatibility issues of customized navigation bar styles to ensure that the application can run smoothly on different mobile devices.
