提问by tugberk
I found this code sample on one of the questions;
我在其中一个问题上找到了此代码示例；
window.onerror = function (msg, url, linenumber) {
//make ajax call with all error details and log error directly into the elmah database
//show freindly error msg here to user

return true;
}
What does 'hide error from browser'means and how can I do that?

return true;
}
})();
