Contents

This component is used for executing JavaScript. The JavaScript to be executed is specified using the Custom Property Sheet (CPS). This component executes the script on documents it receives as input and returns the result.

Icon

The component uses the document object to get the content and properties of the message. The result after executing of the script should be set back onto the document object.
The component uses "bsf" API to evaluate the script.

Points to Note

Input message content and properties can be accessed using document object. For example, 'document.getText()' returns input message content. To access a message property named 'TestProperty, 'document.getRecord().getProperty('TestProperty')' returns the value of the property.
Message properties can be set using 'setProperty' method.
Message properties which are set on input message also appear on output message unless they are changed in the script. For example, if a property named 'TestProperty' is present on input message then output message also contains the property unless it is changed in script provided.
Output message content can be set either by using 'setText(String value)' of document object.
