Initial Description 
Developing a form where I had several date and time fields, I came with a jQuery multiselector where I need to get, through the name attribute, if it was a date or time field. So far, jQuery does not have a boolean method to check if an attribute of an element has a certain value.

This custom method does that. It simple retuns true if the attribute element has a certain value. False if it doesn't.
