How to display errors when using LiveCode Server

All error messages will now be output directly to the browser.

Now I know how to display the errors.

But I also want to treat the error message in the script of iRev file.

Please tell me how this can be done.

To handle errors within your script files, you can use try catch blocks. For example:

try
...
your code
...
catch tError
...
error handling
...
end try
