HTML5’s geo-location application programming interface (API), is to me one of the most interesting features. It enables mobile web sites to access a mobile device’s GPS technology. The W3C geolocation API specification was published in September, 2010. (http://www.w3.org/TR/geolocation-API/)
Google Latitude for the iPhone is one example of a pure HTML5 web application using these features (It’s also available on iPad and Android-powered devices). Latitude lets users share where they are and see where their friends are on a map. Read more at http://code.google.com/apis/latitude/ and http://www.google.com/mobile/latitude/.
Some other application scenarios for using HTML5 geolocation are:
- Finding points of interest in the user’s area
- Showing the user’s location on a map
- Alerts when points of interest are in the user’s vicinity
- Turn-by-turn route navigation
There are more than a dozen new input types and new features that can be used in HTML5 web forms. One of the features enables developers to create and display a placeholder in an input field. What is a placeholder? It is a hint as to what input is expected and what the format should be. When you highlight the field, the placeholder disappears and allows the input.
Another feature is the addition of form validation.
There are many new data inputs supported in HTML5:
- Search – To prompt users to enter text they want to search for.
- Email – For entering a single email address or a list of email addresses.
- Color – For choosing color through a color well control.
- Number Slider – Turns the input field into a numeric slider.
- Web Addresses - Now fields requiring a web address can provide a custom keyboard on iPhones made for entering URLs.
- Numbers - You can now specify minimum and maximun numbers allowed in a particular field, plus what "steps" or increments you allow (i.e. 0, 2, 4, 6 or 0, 5, 10, 15).
