Input constraint "type date"

Question

Code:

<input type="date" name="data" value="">
<input type="submit" class="success round button" value=""/>

I need that when I click the Ubmit button and the date field is blank it doesn’t let me submit. Have some mode in html even without JS to make this restriction ?

Answer 1

You can use the attribute required which is exactly to prevent the field from being sent empty. This HTML5 API feature is supported virtually on all browsers.

Would look like this:

<input type="date" name="data" value="" required>
