Answer 1

If you want to select all elements that have a class attribute that starts with the word btn:

$( '[class^=btn]' )

If you want to use the name attribute instead, just swap out the attribute:

$( '[name^=btn]' )

Using the attribute value starts-with selector: http://api.jquery.com/attribute-starts-with-selector/
