Using Parameters in a Javascript step

[Smoodo]

To use a Parameter inside a JavaScript step using PDI you do the following

Step 1:
Go into the Transformation's properties->Parameter tab
Create a variable, for instance RUNDATE and set a default value, say 07.15.2009.
Click OK.

Step 2:
In the javascript step in PDI, if you wanted to feed that variable in as a Date you would use the following line

StopDate = str2date(getVariable("RUNDATE", "07.01.2009"),"MM.dd.yyyy");

var runDate = getVariable("RUNDATE", "?");

From the sample help code:

// Retrieves the value of a given Kettle/Pentaho Variable
// 
// Usage:
// getVariable(var, var);
// 1: String - The name of the variable to retrieve.
// 2: String - The default if the variable doesn't exist.
//
// 2007-07-27

var strVarName="getVariableTest";
var strVarValue="123456";
Alert(getVariable(strVarName, ""));
setVariable(strVarName,strVarValue, "r");
Alert(getVariable(strVarName, ""));
strVarValue="654321";
setVariable(strVarName,strVarValue, "r");
Alert(getVariable(strVarName, ""));
