Hi, In the context of https://bugs.webkit.org/show_bug.cgi?id=26147 ( No support of DOM events on a frameless document ) I am researching how to implement a fix. I'm thinking of two possible solutions, none of which is trivial. Probably because I'm new to the webkit codebase. a) modify the function void JSEventListener::handleEvent(ScriptExecutionContext* scriptExecutionContext, Event* event) found in http://trac.webkit.org/browser/trunk/Source/WebCore/bindings/js/JSEventListe... so that it does not return without doing anything when there is no frame. However, given the extensive checks related to frames found in the function, I suspect that would cause more problems than it solves. b) modify the function EncodedJSValue JSC_HOST_CALL jsDOMParserPrototypeFunctionParseFromString(ExecState* exec) (or whatever generates this function) to assign the frame() of the global document to it. However, I suspect that this will have a number of undesirable side effects. I'm not sure if there are other ways to look for a solution. I would be very grateful if someone familiar with the codebase could provide me with a hint or point me in the right direction. Thanks in advance
