Using JavaScript to set task parameters

About this topic

JavaScript programs (scripts) can be used to change the parameters of a

 

protocol task immediately before it is scheduled. This extends the

 

capability of VWorks or BenchWorks software because the parameters

 

can be changed dynamically during a run, based on the following:

 

❑ Information passed from an external source, such as a database

 

❑ The number of times the protocol has cycled

 

❑ Feedback on changing conditions during the run

Where scripts are written

This topic describes the use of JavaScript to set task parameters in a protocol.

Read this topic if you are an administrator or technician responsible for creating VWorks or BenchWorks software protocols and want to add functionality to a task using JavaScript.

Scripts can be written in two ways:

❑Directly into the box in the Advanced Settings tab of the Task Parameters toolbar

❑As an external file that is located by clicking Browse in the Advanced Settings tab and navigating to its location on the hard drive

Note: You can also call an external file by embedding the “open()” function in the box.

The following screenshot displays a short script that prints the parameters of a task to the log toolbar, just before the task runs. In this case, the script is written directly in the Advanced Settings box.
