Uniapp removes shadows

Uniapp is an excellent cross-platform development framework that supports writing once and running on multiple terminals. As a developer, you may encounter some problems during development using Uniapp, such as how to remove the shadow effect on the page. In this article, I will share a method to implement Uniapp to remove shadows, I hope it will be helpful to everyone.

First of all, we need to understand the page switching effect of Uniapp. Uniapp uses a page switching animation effect by default, that is, sliding in from the right side, and there is a fade-in and fade-out shadow effect. This shadow effect gives people a three-dimensional sense of page change, but in some scenarios, this effect may not be needed, such as in some simple page designs.

Next, I will introduce how to remove this shadow effect.

Method 1: Modify the global style

We can remove this shadow effect by modifying the global style. The specific implementation method is as follows:

1. Open the Uniapp project and find the "App.vue" file in the root directory.
2. Find the following code:

<uni-transition fade class="app-plus-transition">
  <router-view class="app-plus">
  </router-view>
</uni-transition>

Among them, the <uni-transition></uni-transition> label represents the page switching effect, and fade represents the fade-in and fade-out Effect, <router-view></router-view> tag represents page components.

3. Add the effect attribute in the <uni-transition></uni-transition> tag and set it to slide-left, as follows Shown:

<uni-transition effect="slide-right" class="app-plus-transition">
  <router-view class="app-plus">
  </router-view>
</uni-transition>

Among them, the effect attribute indicates the page switching effect, and slide-right indicates sliding in from the left.

4. Add the style attribute in the <router-view></router-view> tag and set it to background-color: #FFFFFF, as shown below:

<uni-transition effect="slide-right" class="app-plus-transition">
  <router-view class="app-plus" style="background-color: #FFFFFF">
  </router-view>
</uni-transition>

5. Save the changes and re-run the project, you will see the page with the shadow effect removed.

It should be noted that this method can remove the shadow effect of the page switching effect, but it will also remove the shadow effect of the page components. If a page component requires a shadow effect, it can be adjusted through CSS styles.

Method 2: Modify the component style

We can also remove the shadow effect of the page switching effect by modifying the component style. The specific implementation method is as follows:

1. Find Components that need to remove shadow effects.
2. Add the following code in the component's style:

.uni-transition-fade-enter-active, .uni-transition-fade-leave-active, .uni-transition-fade-enter-to, .uni-transition-fade-leave-to {
  background-color: transparent !important;
}

Among them, .uni-transition-fade-enter-active, .uni- transition-fade-leave-active, .uni-transition-fade-enter-to, .uni-transition-fade-leave-to CSS classes representing page switching .

3. Save the changes and re-run the project, you will see the page components with the shadow effect removed.

It should be noted that this method can only remove the shadow effect of one component. If you need to remove the shadow effect of multiple components, each component needs to be modified accordingly.

Summary

Uniapp is an excellent cross-platform development framework that can help developers quickly build cross-end applications. This article introduces two methods to remove the shadow effect of Uniapp pages, one of which is by modifying the global style, and the other is by modifying the component style. I hope these methods can help everyone solve problems in Uniapp development.
