Capture form validation back from the browser

Hyperform is a complete implementation of the HTML 5 form validation API in Javascript. It replaces or polyfills the browser’s native methods and eases your validation task with custom events and hooks.

Download

Hyperform is neatly packed in a single Javascript file, weights only 36kB (10.3kB gzipped!) and includes:

a full, working and compliant implementation of the whole HTML 5 constraint API
```
assert(input.validity.valid);
```

polyfills and ponyfills for other useful methods like valueAsNumber or stepUp

// polyfill:
assert(input.valueAsNumber === 123);

// ponyfill:
hyperform.stepUp(input); // instead of input.stepUp()

new events

form.addEventListener('validate', function(event) {
  // stop the engines!
  event.preventDefault();
});

easily customizable error messages

<input required data-value-missing="No chance! Fill it already.">

fine-grained control over the display of messages
```
.hf_warning {
  border-color: pink;
}
```
