screen spliting with screen

In screen the terminal multiplexer.

  • To split vertically: ctrl a then |.
  • To split horizontally: ctrl a then S (uppercase one).
  • To unsplit: ctrl a then Q (uppercase one).
  • To switch from one to the other: ctrl a then tab

Note: After splitting, you need to go into the new region and start a new session via ctrl a then c before you can use that area.

Biding events to dynamically created html elements
Here is what gets you all the way:
$(document).ready(function() {
$(document).on("click","textarea",function(){
// Do something when textarea is clicked
});
});
If your app is like most web apps, it is probably full of AJAX. Suppose you have a page that renders some buttons or links but it also dynamically adds more of those elements as events happen, such as an AJAX pagination event. To top it off, all those elements have events tied to them (think hitting "Like" on a friends Facebook post that was not initially visible on the page.").
