How to disable F8 key across windows


I have to disable F8 key, but it only applies to the particular page. And within the page, I had embeded a pdf file, the problem now is when I highlight on the pdf file within the page, the F8 is not disabled. It only applies outside the embeded pdf but within the page.



So, I was thinking is there a way to disable F8 across windows with code, I do not want to use any software.

Code:

document.attachEvent("onkeydown", my_onkeydown_handler);
function my_onkeydown_handler()
{
 switch (event.keyCode)
 {
  case 119 : // 'F5'
  event.returnValue = false;
  event.keyCode = 0;
  window.status = "F8 is disabled";
  break;
 }
}
