title: popup loading window
body: <p>I want a popup screen to show the user that "this part" or "that part" of my app is loading....A lot of things within my app is referenced content so sometimes it takes a sec to load...</p>
  
  <p>I'm new to Ajax (so pardon me, please), but I want a popup window to appear to the user in Ajax or JavaScript to let the user know the app is "loading" when the user finger taps something that needs to load....For example content on the new screen....I hope I'm making sense here.... I don't know where to start when it comes to making this happen (cause I'm not a code warrior yet, still a bit green sry lol), so any help is appreciated. I'm using JavaScript and HTML5 so far, but I need a popup loading window widget...</p>
