To implement seamless text scrolling based on Vue, you need to add a window scroll listener through the mounted hook, and in the processing function of the v-on:scroll instruction, the scrollHeight and scrollTop attributes are used to calculate the scrollbar position, thereby updating the Vue data control scroll animation. The steps are as follows: Add mounted hook: Listen to scroll events. Add the v-on:scroll directive: defines the processing function. Write a processing function: calculate the scrollbar position and update the Vue data.
Seamless text scrolling based on Vue
How to achieve it?
Vue-based seamless text scrolling can be achieved by using the Vue lifecycle hook mounted and the Vue directive v-on:scroll :
- In the
mountedhook, add a listener to the window object to listen for scrolling events. - In
v-on:scrolldirective, add a handler to respond to the scroll event. - In the processing function, JavaScript's
scrollHeightandscrollTopproperties are used to calculate the position of the scrollbar. - According to the position of the scroll bar, update the Vue data to control the scrolling animation of the text.
Detailed steps:
1. Add mounted hooks to the Vue component:
<code class="javascript">mounted() { window.addEventListener('scroll', this.handleScroll); }</code>
2. Add v-on:scroll directive in the Vue component:
<code class="html"><div v-on:scroll="handleScroll"></div></code>
3. Write handleScroll processing function:
<code class="javascript">handleScroll() { const scrollTop = document.documentElement.scrollTop; const scrollHeight = document.documentElement.scrollHeight; // 根據(jù)滾動條位置更新Vue 數(shù)據(jù)}</code>
example:
<code class="javascript"><script> export default { mounted() { window.addEventListener('scroll', this.handleScroll); }, methods: { handleScroll() { const scrollTop = document.documentElement.scrollTop; const scrollHeight = document.documentElement.scrollHeight; // 根據(jù)滾動條位置更新Vue 數(shù)據(jù)this.scrollTop = scrollTop; this.scrollHeight = scrollHeight; } } }; </script> <template> <div v-on:scroll="handleScroll"> <!-- 無縫滾動的文字內(nèi)容--> </div> </template></code>
Notes:
- Use
mountedhooks to make sure the listener is added only after the component is loaded. - In the
handleScrollhandler, update the Vue data to trigger re-rendering of the view. - Adjust the calculation logic of the scroll animation to meet specific scrolling effect needs.

How to separate the front and back end of wordpress
Apr 20, 2025 am 08:39 AM
It is not recommended to directly modify the native code when separating WordPress front and back ends, and it is more suitable for "improved separation". Use the REST API to obtain data and build a user interface using the front-end framework. Identify which functions are called through the API, which are retained on the backend, and which can be cancelled. The Headless WordPress mode allows for a more thorough separation, but it is more cost-effective and difficult to develop. Pay attention to security and performance, optimize API response speed and cache, and optimize WordPress itself. Gradually migrate functions and use version control tools to manage code.
