This a good idea, but there is also a bunch of arguments to this function you
could print (notably the error message and line number). For instance

window.onerror = function (errorMsg, url, lineNumber, column, errorObj) {
    alert('Error: ' + errorMsg + ' Script: ' + url + ' Line: ' + lineNumber
    + ' Column: ' + column + ' StackTrace: ' +  errorObj);
}.
