Issue #134  (beforeprint, Text Editors, Git Tools, JS Utils)


(Skip to the tools section below)


Here are two DOM events that I think will be quite useful to many: the beforeprint and afterprint events.

In Microsoft's documentation, beforeprint is explained: "Fires on the object before its associated document prints or previews for printing." Interestingly, the afterprint event is supposed "to undo those changes, reverting the document back to its pre-print or pre-preview state."

These events would trigger whether the browser's print functionality is triggered or just the print preview. MSDN further gives an interesting use case: "This example uses the onbeforeprint to make all hidden sections of the document visible just before the document prints. The onafterprint event is processed after the document prints to return the document to its original state."

Here's how it would look with a couple of simple examples:
 
window.addEventListener('beforeprint', function () { 
  document.body.innerHTML = 'this is before printing';
}, false);

window.addEventListener('afterprint', function () {
  document.body.innerHTML = 'this is after printing';
}, false);

(Try it in JS Bin)

I would think another use case would be to track how many times a user has printed or previewed for printing. This way, you don't have to have an actual print button that checks for click events, and which wouldn't tell the whole story. These events will be triggered regardless of the way the print functionality is used.

Browser support seems to go back to IE8 (maybe even earlier) and these events are also supported in Firefox 6+. So full support isn't too far away. More info:
