C++ (Cpp) JSFunction Examples

Example #1

File: ScriptEventListener.cpp Project: CannedFish/deepin-webkit

bool eventListenerHandlerLocation(Document* document, EventListener* eventListener, String& sourceName, int& lineNumber)
{
    const JSEventListener* jsListener = JSEventListener::cast(eventListener);
    if (!jsListener)
        return false;
    JSC::JSObject* jsObject = jsListener->jsFunction(document);
    if (!jsObject)
        return false;
    JSC::JSFunction* jsFunction = static_cast<JSFunction*>(jsObject);
    if (!jsFunction || jsFunction->isHostFunction())
        return false;
    JSC::FunctionExecutable* funcExecutable = jsFunction->jsExecutable();
    if (!funcExecutable)
        return false;
    lineNumber = funcExecutable->lineNo();
    sourceName = ustringToString(funcExecutable->sourceURL());
    return true;
}
