Depending on each ones needs, we often need ways to detect if our visitors are using an iPad, a smartphone or any other mobile device in order to make out website responsive and even faster by reducing data load. The following are a bunch of classes and snippets you can use to accomplish that, either on the back-end (server side) or on the front-end (client side), depending on each development situation, making it easier to detect mobile devices.

Last updated on by Gabriel Livan

Sometimes it is useful to format user input as they type. It provides a better experience to the user, it shows that you care about visitor’s input and you optimized your web forms like a professional and this way, it’s very unlikely the user will make any typing mistakes as it clearly shows how the input format should be. Here are 2 scripts that you can use to improve the functionality of your forms:

Masket Input Plugin allows a user to easily type in fixed width input in which you would like them to enter the information in a certain format (dates,phone numbers,social security numbers etc). It’s been tested on Internet Explorer, Firefox, Safari, Opera, and Chrome. A mask is determined by a format made up of mask literals and mask definitions. Any character not in the definitions list below is considered a mask literal. Mask literals will be automatically entered for the user as they type and will not be able to be removed by the user.The following mask definitions are predefined:
a – Represents an alpha character (A-Z,a-z)
9 – Represents a numeric character (0-9)
* – Represents an alphanumeric character (A-Z,a-z,0-9)
