Vue realizes vertical text scrolling effect

To implement vertical text scrolling effect in Vue, you need to define the container style (.vertical-scroll-container) for vertical scrolling, and set its height and overflow properties. Defines the style (.vertical-scroll-content) of the text content, position it absolutely, and initializes its position at the top. Use transition animation in Vue component to define the animation effect of text content movement. Use CSS to define transition effects (.vertical-scroll-enter-active and .vertical-scroll-leave-active), and set the transition time and transition type.

Vue realizes vertical text scrolling effect

To achieve vertical text scrolling in Vue, you need to use the transition animation function of CSS and Vue.

CSS

First, use CSS to define the vertical scrolling container style:

 <code class="css">.vertical-scroll-container { height: 500px; /* 容器高度*/ overflow: hidden; position: relative; }</code>

Then, define the style of the text content:

 <code class="css">.vertical-scroll-content { position: absolute; top: 0; /* 初始位置*/ height: 100%; white-space: nowrap; }</code>

Vue transition animation

Next, in the Vue component, use transition animation to control the movement of text content:

 <code class="vue"><template> <div class="vertical-scroll-container"> <transition name="vertical-scroll"> <div class="vertical-scroll-content">{{ text }}</div> </transition> </div> </template> <script> import { ref } from &#39;vue&#39; export default { setup() { const text = ref(&#39;垂直滚动文本&#39;) return { text } } } </script></code>

CSS transition effect

Finally, use CSS to define the transition effect:

 <code class="css">.vertical-scroll-enter-active, .vertical-scroll-leave-active { transition: top 1s ease-in-out; } .vertical-scroll-enter-from { top: 100%; /* 从顶部进入*/ } .vertical-scroll-leave-to { top: -100%; /* 离开到底部*/ }</code>

Running effect

Vue triggers transition animation when text data changes. The text content will enter the container from the top, then scroll down, and finally leave the container from the bottom.

Things to note

• Make sure the container is large enough to hold all text content.
• top value and transition time can be adjusted as needed to customize the scrolling effect.
