Again, previously you had to fiddle around with JavaScript to achieve this very nice (and useful) effect. This allows us to specify some dummy text to appear inside the field, before the user has entered their own text (see screenshot below). This is so much nicer than messing around with JavaScript and regular expressions! Furthermore, some browsers, such as Mobile Safari on the iPhone, will present a keyboard dedicated to entering email addresses (see screenshot below). It behaves much like a regular type="text" field however, HTML5-aware browsers will validate the field automatically, ensuring that the user enters a valid email address. However, the emailAddress input field has some new, exciting HTML5 attributes and values! type="email" This is one of the new input types that HTML5 gives us, and it’s designed specifically for email addresses. You’ll no doubt be familiar with the label and input elements, as well as attributes such as for, type, name, id and maxlength. This goes inside the unordered list in the “License details” fieldset. The first field we’ll add to the form is the “Email address” field. The form ends with a submit button so that the user can send the form. We’ll place our fields inside these lists.

Each fieldset has a legend, and an empty ul (unordered list) element. The form itself consists of an h1 heading, and 3 fieldset elements for the 3 sections of the form. We’re using the HTML5 doctype, adding head and title elements, specifying the utf-8 (Unicode) character set, adding a page title, and creating the basic form. No big surprises here - this is fairly standard stuff. HTML5 Web Form with (almost!) No JavaScript in Sight HTML5 Web Form with (almost!)

It’s an online order form for an imaginary software company. In this tutorial I’m going to walk you through the process of creating a nice, self-validating, widget-rich, HTML5 Web form. Sure, this does mean we’re not exactly banishing JavaScript for now, but at least we can remove it once the browsers catch up! Fortunately, there are a few JavaScript libraries out there that can emulate HTML5 form validation and widgets, as we’ll see later in the tutorial. Hallelujah!Īs with most cutting-edge Web stuff, there’s a catch to all this, and that is browser support (or lack of it). Thanks to the joys of HTML5, we can now create forms with built-in validation and rich widgets for dates, numbers and so on, all without including a single line of JavaScript code. The good news is that these dark days of JavaScript-laden Web forms may soon be coming to an end. Adding decent validation to a form - not to mention creating custom widgets for things like dates and number ranges - is both fiddly and time-consuming.

This means that, when confronted with a new form, a user has to learn the form’s unique quirks and foibles in order to use it.

  • Each Web developer builds their JavaScript form validation and widgets differently.
  • Not all browsers have JavaScript enabled, or can even run JavaScript.
  • While using JavaScript for these purposes is a pretty good solution, it’s not without its problems: JavaScript is also used to enhance forms with additional functionality, such as calendar widgets and the like. Typically this JavaScript is used to validate the form - that is, check all the fields have been filled in correctly before the form is sent to the server. For years now, most Web forms have included at least some lines of JavaScript code.
