If I type too quickly in the input field, it ends up displaying the incorrect div

I need to display two different dropdowns in my input field. To achieve this, I am using a method called shouldShowWarningBox that gets triggered every time the user updates the input and updates the value of showWarningBox accordingly. However, when I type too quickly, I get a false warning message displayed, which is not accurate. If I type slowly, the first dropdown is rendered correctly.

I have experimented with both including and excluding the debounce function, but the behavior remains the same, just with a slight delay.

Any suggestions?

.html

<div v-if="!showWarningBox">
 // First dropdown content
</div>

<div v-if="showWarningBox">
 // Warning message content
</div>

.js

data () {
 return {
  showWarningBox: false,
 }
},
methods: {
 onInput (value) {
  this.debounce(this.shouldShowWarningBox(), 1000)
 },
 shouldShowWarningBox () {
  // Code logic to determine showWarningBox
 },
 debounce (func, delay) {
  let id
 
  return (...args) => {
   if (id) clearTimeout(id)

   id = setTimeout(() => {
    func(...args)
   }, delay)
  }
 },
}

Debounce is a helpful method that creates a throttled function. It is important to assign this debounced function to a component property and invoke it when there is user input:

data(){
  let throttledFunc = this.debounce(this.displayAlertMessage, 1000)
  return {
    throttledInputFunction: throttledFunc
  }
},
methods: {
 onInputChange (inputValue) {
  this.throttledInputFunction()
 },
 //...
}
