Now what if we needed to do this more then just once? Let’s change our html to a more unobtrusive way:
<input type="text" name="birthDate" id="birthDate" data-role="datepicker" />
In this file we make sure we alias ‘$’ to jQuery as another plugin we use could have aliased it differently.
If you are worried about performance of the selector used here, you can always use a class in your convention.
