## Controlling when validation occurs

### Events

By default, validation occurs immediately upon changes to form fields: on `input` for inputs and textareas, and on `change` for selects.

One can change to a different event by setting a field's `data-val-event` attribute. For example, one can use `data-val-event="blur"` to validate that field on the `blur` event.

### Timing

To prevent unnecessary validation, a debounce of 300ms is used. This ensures validation does not occur for every keystroke, which is especially important during remote validation.

In some cases it may be unnecessary, for example when performing local validation on blur (rather than on change). To change the default:

```ts
v.debounce = 0;
```
