How To Suppress All Javascript Runtime Errors?
How can I suppress all JavaScript runtime error popups, from the programmers side?
Solution 1:
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><scripttype="text/javascript">window.onerror = function(message, url, lineNumber) {
// code to execute on an error returntrue; // prevents browser error messages
};
</script>
...
Error Logging is possible too, as explained here
Solution 2:
I made a little script for suppressing an error like "@" does in PHP.
Here is an example.
var at = function( test ) {
try {
if(typeof test === "function") returntest();
elsereturn test || null;
} catch (e) {
returnnull;
}
};
