How to suppress all JavaScript runtime errors?
How can I suppress all JavaScript runtime error popups, from the programmers side?
Answer
To suppress all JavaScript errors there seems to be a window.onerror event.
If it is replaced as early as possible(e.g. right after the head) by a function which returns true - there will be no error popups, which is quite useful after debugging is done.
<head>
<script type="text/javascript">
window.onerror = function(message, url, lineNumber) {
// code to execute on an error
return true; // prevents browser error messages
};
</script>
...
Error Logging is possible too, as explained here
