[Vuejs]-VueJS Value must be a number to be valid

✅

This statement just evaluates whether the wrongNumber method exists on the Vue instance, which will always be true:

if (this.wrongNumber) {

You should call the method and evaluate the result:

if (this.wrongNumber()) {

Or, you might be getting the use of Vue methods confused with the use of Vue computed properties.

If you made wrongNumber a computed property, you could access the returned value via this.wrongNumber like you are trying to do:

methods: {
  isNumeric: function (n) {
    return !isNaN(parseFloat(n)) && isFinite(n);
  },
  validateForm: function (event, $modal) {
    if (this.wrongNumber) {
      event.preventDefault();
      toastada.error('The squares field must contain a number value!');
      return;
    }
    this.saveData($modal);
    return true;
  },
},
computed: {
  wrongNumber: function () {
    return this.isNumeric(this.number) === false
  },
}
