Vue page transition animation implementation and common animation effects-Vue.js-php.cn

Vue is a popular JavaScript framework that uses a data-driven approach to assist developers in building single-page web applications with strong interactivity and beautiful data presentation. Vue has many useful features built-in, one of which is page transition animation. In this article, we will introduce how to use Vue’s transition animation function and discuss the most common animation effects.

Implementing Vue page transition animation

Vue’s page transition animation is through Vue’sandcomponents realized. Below we introduce these two components respectively.

The component can automatically perform transition animation effects when the wrapped element is inserted, updated, or removed.

This component emitsbefore-enter,enter,after-enter,enter-cancelledand # to the outside. ##before-leave,leave,after-leave,leave-cancelledand other hook functions allow us to control the start, end and Cancel.

The following is a simple

animation effect, showing the transition animation of an element when inserted. Please note that this component requires anameattribute, which specifies the name of the animation. In the example below, the animation name isfade. The CSS style here defines the transition animation effect of the element at the beginning and end.

The component is very similar to, but it is suitable for Elements such as list items or tables that need to be inserted and removed at the same time.

Like the

component, hook functions can be defined in thecomponent, such asbefore-enter,enter, etc.

You need to specify atagattribute to specify the type of HTML tag generated by the transition component. It also requires each child element to have a unique key value so that Vue can correctly identify inserted, updated, or removed elements.

In the example below, we show a simple list that adds or removes an item every time a button is clicked. In this example, we use the

component and specify the HTML tag type asul. Each item in the list comes with a key value to help Vue perform the transition animation correctly.
