Using JavaScript in Mirth® Connect

This section shows you how to use JavaScript to perform various messaging operations within Mirth® Connect. About E4X Accessing Message Data with E4X Adding Segments to a Message Segments are a group of fields that can contain varying types of data. Each segment exists independently and can be used in multiple messages. Deleting a Segment Iterating Over Message Segments Iterating Over Repeating Fields Adding a New Repeating Field Message Variables Built-In Code Templates Using Java Classes Regular Expressions Logging with JavaScript Generating a Hash with JavaScript How to generate a hash using Javascript.

External Script Transformer Step

This step functions the same way as the JavaScript Transformer Step, except that the script is read from an external file when the channel is deployed. If the given path is not absolute, it will be relative to the Mirth® Connect installation directory. Parent topic: Transformer Step Properties

Iterator Transformer Step

This is a special type of step that allows you to perform extract / transform operations while iterating through an array or list of XML nodes. For additional information, see Working With Iterators . Item Name Description Iterate On The element to iterate on. This may be a list of E4X XML nodes, or a Java / JavaScript array. Index Variable The index variable to use for each iteration. Drag-and-Drop Substitutions When drag-and-dropping values into the children underneath this Iterator, the index variable (e.g. "[i]") will be injected after any of these prefixes. For example if your index variable is i and you have msg['PID'] in the Drag-and-Drop Substitutions table, when you drag the value msg['PID']['PID.3']['PID.3.1'].toString() from the Message Trees Tab into a child step, it will automatically be replaced with msg['PID'][i]['PID.3']['PID.3.1'].toString().

Mapper Transformer Step

This step extracts data from a field in the message (or an expression) and places it into one of the available Variable Maps. Depending on the scope of the map, this variable will be available in subsequent steps, in the destination connector properties, or even in subsequent connectors. Item Name Description Variable The variable name / key to use when inserting into the map. The Add to drop-down menu to the right determines which map to place the variable in. For additional information, see Variable Maps. Mapping The value to place into the map. This may be a field from the message, or any JavaScript expression. Default Value If the Mapping is not found or evaluates to an empty string, this value / expression will be used instead. String Replacement This table allows you to perform replacements on the value before it gets inserted into the map. Regular Expression: A Java-style regular expression to test against the value. This will implicitly set the global regex flag. Replace With:

Message Builder Transformer Step

This step extracts data from a field in the message (or an expression) and maps it into a specific field in the inbound or outbound message. This can be used to simply modify a field in the inbound message, copy a field from one place to another, or map data from the inbound message to the outbound message. Item Name Description Message Segment The field/location in the inbound or outbound message to place the value into. Mapping The value to place into the given message segment. This may be a field from the message, or any JavaScript expression. Default Value If the Mapping is not found or evaluates to an empty string, this value / expression is used instead. String Replacement This table allows you to perform replacements on the value before it gets inserted. Regular Expression: A Java-style regular expression to test against the value. This will implicitly set the global regex flag. Replace With: The value to replace any matched regions with. Parent topic: Transformer Step Propertie
