When using a v-textarea, is it possible to automatically clear the content after a certain amount of time (2 minutes) if no action is taken? If so, how can this be achieved?
https://i.sstatic.net/16EAj.png
<v-textarea
v-model.trim="text"
clearable
:label="modeLabel"
>
If I were to implement a timer, my approach would be similar to the following:
<v-textarea
v-model.trim="text"
clearable
:label="modeLabel"
@change="clearHandler(event)"
>
let timerID = null;
function clearHandler() {
if (timerID) {
clearTimeout(timerID);
}
// Set up a timer to clear the textarea after a certain time period by resetting the text model
timerID = setTimeout(() => {
this.text = "";
}, 120000);
}
Furthermore, it would be advisable to use this.timerID or employ a ref variable instead of var, depending on the Vue version being used.
By utilizing a straightforward watcher, I have designed this solution. Initially, we establish a function that contains the timeout mechanism. Next, we set up a watcher that is triggered by the variable val. Within this watcher, we invoke the timeout function and then clear the timeout. This setup ensures that the function will be re-executed as needed. Furthermore, the watcher monitors changes to the value; if the user inputs something, the timeout will be canceled.
new Vue({
el: "#app",
data() {
return {
val: ''
}
},
methods: {
timeout() {
return setTimeout(() => {
this.val = ''
}, 5000)
}
},
watch: {
val: {
handler() {
this.timeout()
clearTimeout(this.timeout);
}
}
}

<input v-model="val" />
