The purpose of $('a[href$=".pdf"]'); ?

I don't quite understand what, ("a[href$=".pdf"]" ); part means?

Let's break that expression down into parts:

$(                 );  // create a jQuery object
  'a              '    // by selecting anchor elements (links)
    [            ]     // brackets select by attribute
     href              // look at the "href" attribute
         $=            // check the last part of it
           ".pdf"      // see if it matches ".pdf"

So, all together, what this code does is "find all links that have an "href" attribute that ends in ".pdf" and return the collection of them as a jQuery object."
