POSTED ON:

TAGS: mdn inputs forms

If you want your input value casted as a number, use valueAsNumber

<script>
  const checkMyValueType = (event) => {
    console.log(typeof event.target.value) // string
    console.log(typeof event.target.valueAsNumber) // number
  }
</script>

<input type="number" onkeyup="checkMyValueType(event)" />

double: Returns the value of the element, interpreted as one of the following, in order:
A time value
A number
NaN if conversion is impossible

HTMLInputElement - MDN
