JavaScript Jitterbit and Common Functions¶

Jitterbit JavaScripts can access—in addition to the standard JavaScript functions that are part of ECMA-262 v5.1—these Jitterbit-specific functions. As ECMA-262 v5.1 is an older version of JavaScript than what is commonly available in browsers and other JavaScript engines, we've included tables of the common and standard JavaScript functions that are available in Jitterbit JavaScripts.

Jitterbit Functions¶

Jitterbit.DbExecute¶

Declaration¶

array Jitterbit.DbExecute(string databaseId, string sql)

int Jitterbit.DbExecute(string databaseId, string sql, string outputVariable,...)

Syntax¶

Jitterbit.DbExecute(<databaseId>, <sql>)

Jitterbit.DbExecute(<databaseId>, <sql>, <outputVariable>,...])

Required Parameters¶

• databaseId: A string reference path to a Database connection in the current project
• sql: The SQL command to be executed against the database
• outputVariable: (Second form) An output parameter that is matched to fields returned in the SQL command. Additional arguments can be specified as required.

Description¶

Executes a SQL statement on a database and returns the results. See the Jitterbit Script DBExecute function for details.

The database used in this function call must be defined as a Database connection in the current project. For more information, see the instructions on inserting endpoints under Endpoints in JavaScript.

Jitterbit.DbLookup¶

Declaration¶

string Jitterbit.DbLookup(string databaseId, string sql)

Syntax¶

Jitterbit.DbLookup(<databaseId>, <sql>)

Required Parameters¶

• databaseId: A string reference path to a Database connection in the current project
• sql: The SQL command to be executed against the database

Description¶

Executes a SQL statement on a database and returns the first field of the first result matching the specified criteria. See the Jitterbit Script DBLookup function for details.

The database used in this function call must be defined as a Database connection in the current project. For more information, see the instructions on inserting endpoints under Endpoints in JavaScript.

Jitterbit.GetVar¶

Declaration¶

string Jitterbit.GetVar(string jitterbitVariableName)

Syntax¶

Jitterbit.GetVar(<jitterbitVariableName>)

Required Parameters¶

• jitterbitVariableName: The name of a Jitterbit variable or global variable

Description¶

Returns the value of either a Jitterbit variable (the predefined global variables that are built into Jitterbit Harmony and begin with "$jitterbit.") or another global variable. The dollar symbol is optional and can be omitted. The available variables can be seen in Cloud Studio and are documented under Jitterbit Variables. Global variables defined within the current project can also be retrieved by the same mechanism.

Examples¶

// Retrieves the value of the Jitterbit variable "jitterbit.api.request"
var request = Jitterbit.GetVar("$jitterbit.api.request");

// Retrieves the value of the global variable "email"
var email = Jitterbit.GetVar("email");

// Another method for retrieving a global variable
var email = Jitterbit.GetVar("$email");

Jitterbit.ReadFile¶

Declaration¶

string Jitterbit.ReadFile(string sourceId[, string fileFilter])

Syntax¶

Jitterbit.ReadFile(<sourceId>[, <fileFilter>])

Required Parameters¶

• sourceId: A string reference path to an activity associated with a file-type endpoint in the current project

Optional Parameters¶

• fileFilter: File filter or filename to override the activity configuration

Description¶

Reads the contents of a file from a source.

The source used in this function call must be defined as an activity associated with a file-type endpoint in the current project. These include configured File Share, FTP, HTTP, Local Storage, and Temporary Storage activities. For more information, see the instructions on inserting endpoints under Endpoints in JavaScript.

The method returns the contents of the file pointed to by the source. If the source filter selects more than one file, the first one will be used. It is recommended to specify a source that uniquely identifies a single file.

The parameter fileFilter is optional and can be used to override the file filter used in the activity configuration. A filename can be used. Alternatively, a global variable can be used to override the file filter in the activity configuration. Global variables are referenced as [de_name] in the activity configuration.

If the ReadFile function fails, the operation does not fail. A script will abort, a warning added to the operation log, and the operation will continue.

This method can be used to read data from an HTTP source. In that case, all Jitterbit $jitterbit.source.http.* variables will be populated.

Examples¶

// Reads the first file retrieved from a source
var fileContents = Jitterbit.ReadFile("<TAG>activity:ftp/FTP Endpoint/ftp_read/FTP Files</TAG>");

// Use the filename "test.txt" instead of what is defined in the source
var fileContents = Jitterbit.ReadFile("<TAG>activity:ftp/FTP Endpoint/ftp_read/FTP Files</TAG>", "test.txt");

Jitterbit.SetVar¶

Declaration¶

Jitterbit.SetVar(string jitterbitVariableName, string value)

Syntax¶

Jitterbit.SetVar(<jitterbitVariableName>, <value>)

Required Parameters¶

• jitterbitVariableName: The name of a Jitterbit variable or global variable
• value: A value to be assigned to the variable

Description¶

Sets the value of a Jitterbit variable (the predefined global variables that are built into Jitterbit and begin with "$jitterbit.") or another global variable. The dollar symbol is optional and can be omitted. The available variables can be seen in Cloud Studio and are documented under Jitterbit Variables. Global variables defined within the current project can also be retrieved by the same mechanism.

Examples¶

// Sets a Jitterbit variable and a global variable
Jitterbit.SetVar("$jitterbit.scripting.db.max_rows", 1000);
Jitterbit.SetVar("$email", "first.lastname@example.com");

Jitterbit.WriteFile¶

Declaration¶

void Jitterbit.WriteFile(string targetId, type fileContents[, string filename])

Syntax¶

Jitterbit.WriteFile(<targetId>, <fileContents>[, <filename>])

Required Parameters¶

• targetId: A string reference path to an activity associated with a file-type endpoint in the current project

Optional Parameters¶

• fileContents: Data to be written to the file
• filename: Filename to override the activity configuration

Description¶

Writes the fileContents to the target specified by targetId. If fileContents is of type binary, the binary data is written to the file. In all other cases, a string representation of the data is written. The file is automatically flushed and closed by the function.

The target used in this function call must be defined as an activity associated with a file-type endpoint in the current project. These include configured File Share, FTP, HTTP, Local Storage, and Temporary Storage activities. For more information, see the instructions on inserting endpoints under Endpoints in JavaScript.

The third parameter, filename, is optional and can be used to override the filename used in the activity configuration. Alternatively, a global variable can be used to override the filename in the activity configuration. Global variables are referenced as [de_name] in the activity configuration.

This method can also be used to write/post data to an HTTP target. In that case, $jitterbit.target.http.* variables will be populated.

If the WriteFile() function fails, the operation does not fail. A script will abort, a warning added to the operation log, and the operation will continue.

Examples¶

//  Writes the value of $contents to the file defined by a target
Jitterbit.WriteFile("<TAG>activity:ftp/FTP Endpoint/ftp_write/FTP Files</TAG>", $contents);

// Use the filename "test.txt" instead of what is defined in the target
Jitterbit.WriteFile("<TAG>activity:ftp/FTP Endpoint/ftp_write/FTP Files</TAG>", $contents, "test.txt");

SetScriptOutput¶

Declaration¶

void SetScriptOutput(string data)

Syntax¶

SetScriptOutput(<data>)

Required Parameters¶

• data: Data to be returned by the script

Description¶

Sets the value returned by a script.

The return value of a script can be accessed as the return value of the RunScript function.

Examples¶

// In the calling Jitterbit Script script:
$result = RunScript("<TAG>script:CalculateSomething</TAG>", value_to_be_calculated);

// In the Jitterbit JavaScript script "CalculateSomething":
var calculated_value = ...;
...
SetScriptOutput(calculated_value);

SetScriptResult¶

Declaration¶

void SetScriptResult(string data)

Syntax¶

SetScriptResult(<data>)

Required Parameters¶

• data: Data to be returned by the script

Description¶

An alias for the SetScriptOutput function. See SetScriptOutput for details.

WriteToOperationLog¶

Declaration¶

string WriteToOperationLog(string message)

Syntax¶

WriteToOperationLog(<message>)

Required Parameters¶

• message: A string message

Description¶

Writes a message to the operation log.

Examples¶

// Writes a message to the operation log
WriteToOperationLog("The source field 'Price' has an invalid value.");
