How to quickly execute functions for vue

How to quickly execute functions in Vue.js includes: using the v-on directive to bind event handling functions. Use ref to refer to the method or property of the calling element. Use the $nextTick method to queue the function to execute in the next event loop.

How to quickly execute functions in Vue.js

In Vue.js, there are several ways to execute functions quickly:

1. v-on command

The v-on directive is used to bind event handlers. You can use the v-on directive to assign a function directly to a specific event. For example:

 <code class="html"><button v-on:click="myFunction">点击我</button></code>

When the user clicks a button, the myFunction function will be called immediately.

2. ref quote

The ref reference allows you to access a DOM element or Vue instance. You can use ref references to call the element's methods or properties to achieve quick execution of functions. For example:

 <code class="js">export default { methods: { myFunction() { console.log('函数已执行') } }, mounted() { this.$refs.myElement.myFunction() } }</code>

In the mounted hook function, the ref reference of the component instance will immediately call the myFunction function.

3. $nextTick

The $nextTick method allows you to queue the function to be executed in the next event loop of Vue. This is very useful for executing functions after DOM updates. For example:

 <code class="js">export default { methods: { myFunction() { console.log('函数已执行') } }, mounted() { this.$nextTick(() => { this.myFunction() }) } }</code>

In the mounted hook function, the myFunction function will be queued to execute in the next event loop after the component is mounted.
