try
The try
structure attempts to execute the following statements. If a script error is triggered, instead of interrupting the script, the statements under the catch
clause, if specified, are executed. The text of the error message is stored in the specified variable. The statements under the finally
clause, if specified, are always executed regardless of whether or not a script error is triggered.
