jQuery's method of matching document links and adding classes_jquery

The example in this article describes how jQuery matches document links and adds classes. Share it with everyone for your reference. The details are as follows:

JQuery is used here to automatically discover links to documents and add classes, such as doc, xls, and pdf documents.

$('a[href]').each(function() {
  if((C = $(this).attr('href').match(/[.](doc|xls|pdf)$/))) {
    $(this).addClass(C[1]);
  }
});

I hope this article will be helpful to everyone’s jQuery programming.
