Hello. I'm trying to hook to JavaScript events so I could listen to events and recognize when my action on a page has called a JavaScript function. I've found the JSEventListener::handleEvent() method that receives events and tries to execute the JS code with:
JSValue retval = handleEventFunction ? JSC::call(exec, handleEventFunction, callType, callData, jsFunction, args) : JSC::call(exec, jsFunction, callType, callData, toJS(exec, globalObject, event->currentTarget()), args); The problem is whenever I look at the type of JSValue it's always "undefined or null" (retval.isUndefinedOrNull()). I've binded my own JS callback functions outside the WebKit engine from my C program which uses WebKit and the callbacks return booleans (return JSValueMakeBoolean(ctx, true)). Then I binded my JS function to a page element that calls the function when clicked. Because the return value of retval should be boolean I don't know why I'm getting different results. Maybe I don't fully understand the retval JSValue. Is retval the right way to check return values of my binded _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org http://lists.webkit.org/mailman/listinfo.cgi/webkit-dev
