/*--- waitForKeyElements(): A utility function, for Greasemonkey scripts,
that detects and handles AJAXed content. Forked for use without JQuery.
Usage example:
waitForKeyElements (
"div.comments"
, commentCallbackFunction
);
//--- Page-specific function to do what we want when the node is found.
function commentCallbackFunction (element) {
element.text ("This comment changed by waitForKeyElements().");
}
IMPORTANT: Without JQuery, this fork does not look into the content of
iframes.
