onerror problem

[josh]

Hi

if I try to attach onerror event via addEventListener

window.addEventListener("error", myError, false) it does not work
as it pass to myError only the event object but not the three
parameters
error message, url, line number as in: window.onerror = myError
infact if I assing it via window.onerror = myError it works!

any idea?

Novel idea: Use window.onerror=myError instead of addEventListener and
all is fine with the world.......

All is fine with the world as long as nothing else was already assigned
as the handler. If it was, then it's nuked.

You can try the following (works in IE and Firefox at least):

function addWindowOnerror(fn) {
var oFn;
if (typeof window.onerror == 'function') {
oFn = window.onerror;
window.onerror = function(a, b, c){
oFn(a, b, c);
fn(a, b, c);
}
} else {
window.onerror = fn;
}
}
