To recap—or in case you haven’t read Sandeep’s article—with the dawn of HTML5, a raft of new input types and attributes were added to tags that allow the browsers themselves to perform the client-side validation for us: no Java Script required.To start using the new input types and attributes, you don't really need to do anything other than start using the new input types and attributes.So if an older browser doesn't support them, the fact that they're in the HTML won't 'break' anything, they’ll just be rendered as an .NB While client-side form validation is great for enhancing user experience—fast, instant feedback to the user without making a round trip to the server—you will still need to validate any data submitted on the server, too.We then looked at how new CSS3 pseudo-classes can be used to give visual cues to the user as to which fields are required and options, and which contain valid or invalid data.Finally we covered how to disable HTML form validation, and detect whether form validation was available or not in case we have to support browsers that are yet to support this feature.We'll want the 'Name' field to be submitted in the format 'Firstname Lastname', and to only contain letters and a space (NB in real world scenarios, you might need to take account of other locales – this example has been kept simple deliberately).We can achieve this by adding a pattern attribute to the 'Name' field, setting it's value to the regular expression we want the data to be compared against: The text in the title attribute is then appended to the built-in validation message: Note that some screen reader / browser combinations might lead to the title attribute being read out in addition to the aria-describedby text, so watch out for this e.g.
In tandem with the new input types and attributes provided by HTML5, CSS3 gives us some new pseudo-classes we can use to provide visual clues to the user as to which form fields are required, which are optional, and which contain validation errors.
This keeps our HTML semantic, with the labels helping to give meaning to the input controls.
It also means that if you click the label, the associated input tag receives the focus.
I found that using NVDA with IE10 caused the title attribute and the aria-describedby element's text to be read out, but using NVDA with Chrome and Firefox didn’t exhibit this behaviour. Later on we’ll revisit this and show you one solution using CSS3.
To make sure our user enters the right data in the email, website, and number of tickets fields, we can use some of the new input types added in HTML5: By specifying the appropriate type, our browser will validate the data for us and make sure we've got an email address in the email field, a URL in the website field, and a number in the number of tickets field.
