Content kopiëren
Ik heb een uploader gemaakt: http://powarimages.netii.net/uploader.php
Nu zou ik graag willen dat de URL naar je afbeelding wordt gekopiëerd naar je klembord, zodra je achter het textvak (eigenlijk een input tag) op iets als Kopiëren klikt.
Ik neem aan dat dit met javascript, of flash moet oid.? Maar is daar een script van? Ik heb al op google gezocht, maar dat is allemaal voor textvakken.
Mijn code van de uploader:

Kijk hier eens: hierzo. Misschien heb je daar wat aan.
De code, voor het gemak:
function copyToClipboard(text)
{
if (window.clipboardData) // IE
{
window.clipboardData.setData("Text", text);
}
else
{
unsafeWindow.netscape.security.PrivilegeManager.enablePrivilege("UniversalXPConnect");
const clipboardHelper = Components.classes["@mozilla.org/widget/clipboardhelper;1"].getService(Components.interfaces.nsIClipboardHelper);
clipboardHelper.copyString(text);
}
}

De code die jij geeft is bedoelt voor een GreaseMonkeyscript en werkt alleen in IE en FF.
(unsafeWindow -> GM; const, Components -> FF).
Een flash bestand zou beter werken als alternatief voor die else-constructie:
