Do not use submit to name a submit button

Written byPhuoc Nguyen

Given a form element, we often call the `submit()` method to submit the form after validating its fields.
If the submit button of the form has either `name="submit"` or `id="submit"` attribute, then `formEle.submit` will return the submit button instance. As a result, `formEle.submit()` throws an exception because it's not an actual function anymore.
We can face the similar issue when using special properties of form such as `reset`, `length`, `method`.
<!-- Do NOT -->
<button type="submit" name="submit">Submit</button>
<button type="submit" id="submit">Submit</button>

<!-- Do -->
<button type="submit" name="submitButton">Submit</button>
