How to use vue timer

Vue.js provides setInterval() and clearInterval() methods to create and clear timers. To create a timer, you need to pass a callback function and trigger interval time, and return a timer ID; to clear the timer, you need to pass the corresponding timer ID.

Use of Vue timer

Vue.js provides setInterval() and clearInterval() methods to create and clear timers.

Create a timer

To create a timer, use setInterval() method:

 <code class="javascript">const timerId = setInterval(() => { // 每隔指定毫秒执行此函数}, milliseconds);</code>

setInterval() method accepts two parameters:

• Callback function: The function to be executed when the timer is triggered.
• Milliseconds: The interval time (in milliseconds) of the timer trigger.

setInterval() returns a timer ID ( timerId ) to identify the timer.

Clear the timer

To clear the timer, use clearInterval() method:

 <code class="javascript">clearInterval(timerId);</code>

clearInterval() method accepts a timer ID as a parameter and stops the timer.

Example

Here is an example of how to use setInterval() and clearInterval() :

 <code class="javascript">// 创建一个每秒触发一次的计时器const timerId = setInterval(() => { console.log('计时器触发'); }, 1000); // 5 秒后清除计时器setTimeout(() => { clearInterval(timerId); }, 5000);</code>

This code will print a "Timer Trigger" message every second and clear the timer after 5 seconds.
