Modified Java Script
Description
Modified Java Script is a step in the Scripting Plugin for Process Studio Workflows. It is an easy, expression based user interface for building JavaScript expressions. This step also allows you to create multiple scripts for each step. Please keep in mind that this step has performance disadvantages due to the fact that it is interpreting the JavaScript. Please see the other steps in the 'Scripting' section when performance is critical for you.

You can insert functions, constants, input fields, etc. from the tree control on the left by double-clicking on the node you wish to insert or by ragging the object onto the Java Script panel. There are two versions of the javascript engine: the 2.5 version and the 3 version. If "compatibility mode" is checked (and by default it is), javascript works like it did in version 2.5. Obviously the new version should be used if possible so uncheck "compatibility mode" if yo u can. |
