How to write a vue timing function

Vue provides four built-in timing functions: setTimeout, setInterval, clearTimeout, and clearInterval, which can be used to schedule specific times or execute tasks at specific intervals. The usage method is as follows: setTimeout(callback, delay): Set delay to execute one-time tasks, delay is the delay time (milliseconds). setInterval(callback, delay): Sets the timed execution of tasks, delay is the execution interval (milliseconds). clearTimeout(timerId): Clear the timer returned by setTimeout. clearInte

Vue timing function

Several built-in timing functions are provided in Vue for scheduling tasks at specific times or at specific intervals.

setTimeout

• <code class="javascript">setTimeout(callback, delay)</code>

• callback : The function to be executed.

• delay : Delay time in milliseconds.

  setInterval

• <code class="javascript">setInterval(callback, delay)</code>

• callback : The function to be executed regularly.
• delay : The interval between two calls to the function (in milliseconds).

clearTimeout

• <code class="javascript">clearTimeout(timerId)</code>

• timerId : The timer ID returned by setTimeout .

  clearInterval

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

• timerId : The timer ID returned by setInterval .

Example of usage

Here are some examples of using Vue timing functions:

• Perform one-time tasks after 2 seconds:

  <code class="javascript">setTimeout(() => { console.log("任务已完成！"); }, 2000);</code>

• Execute tasks once a second:

  <code class="javascript">const intervalId = setInterval(() => { console.log("任务已完成！"); }, 1000);</code>

• Clear the timer:

  <code class="javascript">const timerId = setTimeout(() => { console.log("任务已完成！"); }, 2000); // 在任务执行前取消定时器clearTimeout(timerId);</code>
