Restrict input to allow only required value (jQuery plugin for input type validation)

HTML5 provides many validation on input, but still few we need to implement by our self. For example, if we need one input for price then we should allow users to enter only float values. I created one small plugin using jQuery, it is very easy to use.

To create one input with only price value then just include attribute "only-price"

To create one input with only number (contact) value then just include attribute "only-number"
