Primitive Type and Validity Checking

• Use a type attribute on an input element

• Web Forms 2.0 aware browsers can:

  • use custom controls (e.g. a calendar for a date)

  • check the validity of submitted data

• Web Forms 2.0 unaware browsers can ignore this and operate as normal

<label>E-mail address: <input type="email" name="addr"></label>
<p>
  <label>Start date: <input type="date" name="start"></label>
</p>
