I have a page with a document.onkeydown
event handler, and I'm loading it inside an iframe in another page. I have to click inside the iframe to get the content page to start "listening".
Is there some way I can use JavaScript in the outer page to set the focus to the inner page so I don't have to click inside the iframe?
EDIT: response to comment:
The context is the main window is a light-box-like system, except instead of pictures, it shows iframes, and each iframe is an interactive page with keydown/mousemove handlers. these handlers don't fire until I click in the iframe after showing the light-box-thing.
I'm not actually looking to "setFocus" in the traditional sense as much as "enable event handlers on the iframe contentDocument"
I had a similar problem with the jQuery Thickbox (a lightbox-style dialog widget). The way I fixed my problem is as follows:
function setFocusThickboxIframe() {
var iframe = $("#TB_iframeContent")[0];
iframe.contentWindow.focus();
}
$(document).ready(function(){
$("#id_cmd_open").click(function(){
/*
run thickbox code here to open lightbox,
like tb_show("google this!", "http://www.google.com");
*/
setTimeout(setFocusThickboxIframe, 100);
return false;
});
});
The code doesn't seem to work without the setTimeout(). Based on my testing, it works in Firefox3.5, Safari4, Chrome4, IE7 and IE6.
