uniapp hides top navigation bar

In the process of using Uniapp for mobile application development, we often need to hide or show the navigation bar of the page to achieve different visual effects or functional requirements. This article will introduce how to hide the top navigation bar of Uniapp page.

1. Use the jump method to jump to the page

When using Uniapp to jump to the page, we can use APIs such as uni.navigateTo or uni.redirectTo. These APIs allow us to pass some parameters to control the behavior of page jumps.

Among them, we can use the "animationType" parameter of uni.navigateTo or uni.redirectTo to control the animation effect of hiding the top navigation bar when the page jumps. The specific code is as follows:

uni.navigateTo({
  url: 'your_url',
  animationType: 'slide-in-right',
  animationDuration: 300,
  success: function () {
    uni.hideNavigationBarLoading()
  }
})

2. Using the navigation bar slot in the page component

In the Uniapp page component, we can use code like ca24b4e6055209b9acbe55e0709d6321@{{title}}7971cf77a46923278913ee247bc958ee Insert the navigation bar component. If we need to hide the navigation bar, we only need to comment out this code or set its content to empty.

For example, in the template part of the vue file, we can write like this:

<template>
  <div class="container">
    <!--<slot name="title">@{{ title }}</slot>-->
    <div class="content">
      ...
    </div>
  </div>
</template>

After doing this, the navigation bar of the page will be hidden.

3. Use global styles in App.vue

If we need to hide the top navigation bar of all pages in the entire Uniapp application, we can use global styles to set it in App.vue .

In the style section of App.vue, we can set the margin-top attribute to 0 for the html element of the page, and move the content of the page upward to cover the top navigation bar. The specific code is as follows:

<style>
  html {
    margin-top: 0;
  }
</style>

In this way, we can hide the top navigation bar of all pages throughout the entire life cycle of the application without the need for separate settings in each page component.

4. Use the uni.hideNavigationBar method

The last method is to use the uni.hideNavigationBar method. This method allows us to dynamically control the display or hiding of the navigation bar during the life cycle of the page.

In the created, mounted and other life cycle methods of the page, we can call uni.hideNavigationBar() to hide the navigation bar of the page. The specific code is as follows:

export default {
  name: 'YourPage',

  data() {
    return {
      ...
    }
  },

  created() {
    uni.hideNavigationBar()
  },

  methods: {
    ...
  }
}

Using this method, you can dynamically control the display or hiding of the navigation bar in the page component, which is more flexible and convenient.

This article introduces four methods to hide the top navigation bar of the Uniapp page, including using the jump method to jump the page, using the navigation bar slot in the page component, and Use global styles and use the uni.hideNavigationBar method in App.vue.
