The JavaScript Editor and Debugger lets you trace the execution of a script. You can step through a code
line-by-line or step through from one breakpoint to another. You
can check the current value of a variable at any time.
Note:
A comment line starts with two forward slashes (//) at
the beginning of the line.
To
validate JavaScript code, select Debug > Start. The result
of the validation appears in the Tasks tab.
Stepping Through the Code
The JavaScript Editor and Debugger works without input data at the IN-port of the component. However, for best results, populate the IN-port with data before using the debugging features.
Adding and Removing Breakpoints
Include breakpoints at selected lines instead of stepping through the procedure line-by-line.
