User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release) Build ID: 20140314220517 Steps to reproduce: According to html5 onerror handler for body and frameset elements should be exposed on window (http://www.w3.org/html/wg/drafts/html/master/webappapis.html#event-handlers-on-elements,-document-objects,-and-window-objects) and it is correct, but we don't have access to event object, we get only a string (like e.message). Chrome working correctly, IE doesn't expose this event when use handler on body/frameset. Other event handler, like onload, onunload, onresieze works fine. If I find similar inconsistencies for event handler I will put them in this place. Some test for better understanding: <!DOCTYPE html> <html> <head> </head> <body> <p>Generate error for script (when running).</p> <p style="color: blue;">Detailed information for the captured events:</p> <p id="info"></p> <script> var info = document.getElementById("info"); function readInfo(e){ var data = "Interface: " + e + "<br>" + "e.type: " + e.type + "<br>" + "e.currentTarget: " + e.currentTarget + "<br>" + "e.target: " + e.target + "<br>" + "e.eventPhase: " + e.eventPhase; // Only for script error if (e == "[object ErrorEvent]"){ data += "<br>" + "e.message: " + e.message + "<br>" + "e.filename: " + e.filename + "<br>" + "e.lineno: " + e.lineno + "<br>" + "e.colno: " + e.colno + "<br>" + "e.error: " + e.error + "<br><br>"; } else{ data += "<br><br>"; } info.innerHTML = info.innerHTML + data; } document.body.onerror = readInfo; document.body.addEventListener("error", readInfo, true); // without invoke (correct) document.body.addEventListener("error", readInfo, false); // without invoke (correct) makeError(); // generate some JS error (undefined method) </script> </body> </html>
