title: jQuery: How do I get the contents of a span, subtract by 1, and replace contents of span with new number?
body: <p>Let's say I have a PHP loop that displays data that you can delete. I'm using AJAX, so when you delete a row, it processes a PHP script and the row disappears from the page.</p>
  
  <p>However, I have something that says "There are 5 items". I'd like that "5" to change when an item is deleted. I figured the easiest way would be to subtract by one in Javascript.</p>
  
  <p>Problem is, I really don't know how. If someone could point me in the right direction, that would be great.</p>
