javascript - Listen for keypress while iframe has focus? - Stack Overflow

Is there any way to listen for keypress events in a parent page while the iframe has focus? Or, alternatively, is it possible to pull away the focus from the iframe?

Please note, the iframe is not within the same domain, so I cannot modify its contents via javascript.

I've tried the following jquery in the parent page, thinking perhaps an intermittent blur would work, but it doesn't seem to.

function iframeBlur(){
    $("#iframe").blur();         
}
var blurif = setInterval(iframeBlur, 500);

• I just noticed that setting the focus to an input element works. Is it really the best solution though? I would have to create a hidden input element, and then test to see if other inputs are currently being focused (in which case i shouldn't refocus). – Matrym Commented Apr 9, 2010 at 9:42

It looks like I just had the wrong syntax. window.focus(); works in ffx and chrome (I've got to resolve other ie bugs first before i know with that).

function iframeBlur(){
    window.focus();  
}
var blurif = setInterval(iframeBlur, 500);

I'm pretty sure this is not possible, iframes are pretty extensively protected from the parent JavaScript. This is a good thing for security reasons. Otherwise a hacker could register something like gmai1., have a big iframe with the real gmail. and then log password entries from the parent.
