Using id selector will be fast always as it returns single element but class selector will return one or more elements.
NOTE - You must ensure that id should be unique through out the DOM.

But in both cases it may iterate throw the DOM? – Fury Feb 05 '15 at 06:24

but search criteria is more restrictive using ID selector, hence once it finds element it will stop searching. – Bhushan Kawadkar Feb 05 '15 at 06:25

in case of id I need to write 100 selector But if I use class then a single line code can be sufficient. So What if Class is used to improve maintainability of Jquery code. – Anil Anjana Feb 05 '15 at 06:39

Yes, for handling 100s of element, class is better choice instead of id. This will be easy for maintainability and extensibility. – Bhushan Kawadkar Feb 05 '15 at 06:42
