Javascript-форум - Iframe в букмарклете

Нет... готов поспорить.

Есть код:

(function() {
var doc = top.document,
iframe = doc.getElementById("bitmark_yoself_fool"),
script = doc.getElementById("bitmark_js");
if (iframe && script) {
alert("bitmarklet is already running... \n close it out first if you want to start over")
return;
}
if (iframe && iframe.parentNode) {
iframe.parentNode.removeChild(iframe);
}
if (script && script.parentNode) {
script.parentNode.removeChild(script);
}
var u = top.location.href,
t = doc.title;
var target_el = getTargetEl(),
target_el_body = target_el.body,
iframe = document.createElement("iframe"),
script = doc.getElementById("bitmark_js"),
iframe_id = "bitmark_yoself_fool",
body_old_className = target_el_body.className || "";
target_el_body.className = [body_old_className, "bitmarklet_on"].join(" ");
var text;

target_el_body.appendChild(iframe);

И он спокойно везде вызывается с помощью этого букмарклета:
