JavaScript Evaluation
From STIQ
Javascript evaluation provides the full power of javascript in constructing a command parameter. To use this mechanism, the entire parameter value must be prefixed by javascript '{' with a trailing '}'. The text inside the braces is evaluated as a javascript expression, and can access previously stored variables using the storedVars map detailed above.
Note that variable substitution cannot be combined with JavaScript evaluation.
Example:
store javascript{'merchant' + (new Date()).getTime()} merchantId type textElement javascript{storedVars['merchantId'].toUpperCase()}
