HTML5 defines a variety of new input types: The beauty of these elements is that you can use them now: There are two keys to understanding why the automatic fallback works consistently in all major browsers:. For each of the new input types, we present a high-level description, an overview of the syntax, a description of the main attributes, a summary of which current browsers support it, and an example you can experiment with in your browser.

Please send corrections and suggested improvements to hall coreservlets. Overview For each of the new input types, we present a tabbed panel similar to the following.

Description Syntax Attributes Browser Support Samples A high-level description of what this input type does in browsers that support it. The main element-specific attributes used by this input type if any.

A summary of which browsers support this feature. As of January , Opera had the most complete support for these new input elements, followed closely by Chrome. Firefox and Safari had moderate support, and Internet Explorer had no support at all. For each type of input element, we use the modernizr. You are currently using document. The first sample HTML5 uses the new input type. Try using it to enter data of proper and improper types and see what you get in your browser.

If your browser does not support this element type, then the two versions should look and act exactly the same. Description Syntax Attributes Browser Support Samples This input type lets you collect a number either integer or floating point. All known browsers that support this use a spinner. You should normally supply all of value, min, and max. Browsers that support this input type give inconsistent behavior when these attributes are omitted. If you want to collect floating point numbers, use a non-integer for min or step.

If omitted, the field is initially blank, but the internal value is not consistent across browsers. How much to change the value when you click on the up or down arrows of the control. The default is 1. However, Chrome lets you type values outside that range directly into the textfield, and then gives no error when you submit.

Opera also lets you type values outside the range, but gives an error when you try to submit.

However, the Opera error message incorrectly refers to the maximum value, so is of little use in the current version. See the Browser Support section for an Opera screen shot. I tested number input on the latest versions of the five most popular browsers on Windows.

Here are the results as of January Pre-HTML5 Choose even number All known browsers that support this use a slider. The exact value is not displayed to the user unless you use JavaScript. So, use the number spinner input type if you want to let the user choose an exact value. Browsers are supposed to use a horizontal slider unless you attach CSS that specifies a smaller width than height, in which case they are supposed to use a vertical slider.

Unlike with the number spinner input type, the range slider input type has reasonable defaults for min, max, step, and value. The default is halfway between the min and the max. The smallest and largest values that can be selected.

The default for min is 0, and the the default for max is I tested range input on the latest versions of the five most popular browsers on Windows. Pre-HTML5 Choose number Description Syntax Attributes Browser Support Samples This input type lets you collect a date.

Chrome and Opera use a textfield with a calendar that pops up when you clieck in the textfield, and it is expected that this is what most future browsers will do. Safari uses an interface that looks like a number spinner but increments the yyyy-mm-dd string one day at a time. As of January , neither Firefox nor Internet Explorer has any support at all for date input. Note that the modernizr.

In Opera and other future browsers that pop up calendars, the calendar selection defaults to the current date. So, all of value, step, min, and max can be omitted. The Chrome behavior is unhelpful, since you will need JavaScript to calculate the current date at run time.

Also, if you have two related date input fields e. The format is "yyyy-mm-dd". The step size in days. The smallest and largest dates that can be selected, formatted as date strings of the form "yyyy-mm-dd". I tested date input on the latest versions of the five most popular browsers on Windows. Hopefully, future Chrome versions will use a popup calendar. Same as ordinary textfield: Description Syntax Attributes Browser Support Samples This input type lets you collect a color of the form rrggbb.

If your browser supports color input, clicking in the top entry should result in a color chooser popping up.

Note that the new and poorly named HTML5 "autocomplete" attribute is not used for these lists of choices, but instead is a flag that tells the browser whether or not it should used stored form values from previous sessions.

Sadly, the HTML5 autocompletion has no options for customizing the look, for using HTML in the autocomplete list, or for defining how the match against the choices is performed.

The input element list: The id of a separate "datalist" element that defines a list of choices for the user to choose among.

The option element inside "datalist" label: Extra information that may be displayed in the autocomplete list. Browsers might show this label or a combination of the label and the value. The label is never part of the value that is inserted into the textfield when the entry is selected. The value that should be inserted into the textfield when the entry is selected. I tested autocompletion i. See later sections on email and URL input for support for autocomplete lists with those textfield types.

Pre-HTML5 Choose Employee ID: Description Syntax Attributes Browser Support Samples This input type lets you collect an email address. If the "list" attribute is not specified, then the intention is that the browser supplies some help in entering a legal email address e. As of January , the latest versions of Chrome and Safari claim to support email input, but have no difference in look or behavior. As of January , the latest version of Opera has no difference in look on input, but performs email address validation on submission.

If the "list" attribute is specified, then the intention is that the browser lets the user choose among a set of email addresses defined separately with the "datalist" element. If you supply the "list" attribute, you must also supply a separate "datalist" entry. The initial value a legal email address.

The id of a separate "datalist" element that defines a list of email addresses for the user to choose among. I tested email input on the latest versions of the five most popular browsers on Windows.

Safari claims to support URL input, but has no difference in look or behavior. The latest version of Opera has no difference in look on input, but performs minor editing on change and validates illegal characters on submission. On change, Opera adds "http: The definition of onchange is when you enter something and then click in a different textfield or otherwise have the original textfield lose focus.

On submission, Opera gives an error message if the URL contains illegal characters, but does not do full URL validation e. If the "list" attribute is specified, then the intention is that the browser lets the user choose among a set of URLs defined separately with the "datalist" element. The initial value, as an absolute URL. The id of a separate "datalist" element that defines a list of URLs for the user to choose among.

However, since the format of telephone numbers is not specified, it is not clear how a normal browser would help you with this. However, a cell phone might use an on-screen keyboard that is optimized for phone number input. As of January , Firefox, Chrome, Safari, and Opera claim to support telephone input, but show no difference when entering values and perform no validation when submitting values. The initial value as a phone number.

I tested telephone input on the latest versions of the five most popular browsers on Windows. Pre-HTML5 Enter phone number: Description Syntax Attributes Browser Support Samples This input type is intended to help you collect a string for a search. Since search queries are free-form text, there is never any help in inputting characters, and never any validation on submission. However, on some platforms, search fields should look slightly different than regular textfields e.

However, on Windows, as of January , no tested browser showed any difference whatsoever, even when as with Firefox, Chrome, Safari, and Opera the browser claimed to support search input.

I tested search input on the latest versions of the five most popular browsers on Windows. Description Syntax Attributes Browser Support Samples Adding the "placeholder" attribute lets you add a hint inside the textfield, but where the hint automatically disappears when you click inside it.

This is like the "Password" text inside the textfield in the Windows login window. The input element placeholder: This differs from the "value" attribute in two ways.

First, it will usually be rendered differently e. Second, it will automatically disappear when you click in the textfield. If you have both placeholder and value, the value wins, and placeholder is ignored.

Pre-HTML5 Enter Employee ID: HTML5 Enter Employee ID: Description Syntax Attributes Browser Support Samples Adding the "pattern" attribute lets you specify a regular expression in JavaScript RegEx format for legal values.

This is particularly useful when the legal pattern is clear from the prompt, or when you use "placeholder" to describe the pattern. As of January , Firefox, Chrome, and Opera give an error message on form submission when the value fails to match the pattern; however, the error message is pretty generic "Please use the required format" , and thus does not give the user much help with how to correct the error.

But, if you also add placeholder text or regular text telling the user what format to enter, this error message may be quite helpful. On attempted submission, Safari underlines bad values in red and blocks the submission. A JavaScript regular expression.

Description Syntax Attributes Browser Support Samples Adding the "required" attribute lets you specify that the user must enter a value before submitting the form. As of January , Firefox, Chrome, and Opera give an error message on attempted form submission when the textfield is empty. Safari claims to support "required", but in actuality do nothing with it.
