Job and order parameters can be set using global variables. A simple example would be:
<param name="BookingDate" value="\$ODAT">
where the global variable $ODAT represents a date and has been set as described in the Creating_global_variables FAQ. Substituting a job or order parameter in this way would allow, for example, a booking date to be set for a financial transaction although the transaction is actually processed at a later time.
The following is a more complex example showing the substitution of global variables in a job:
function spooler_task_before() \{
var paramNames = spooler_task.params.names.split( ";" );
for( var i in paramNames ) \{
substituteParams(paramNames[i]);
\}
return true;
\}
function substituteParams(paramName) \{
var paramValue = spooler_task.params.value(paramName);
if(paramValue.search(/\$/) > -1) \{
var schedulerParamNames = spooler.variables.names.split( ";" );
for( var i in schedulerParamNames ) \{
if(paramValue.search(/\$/) == -1) \{
break;
\}
var schedulerParamValue = spooler.variables.value(schedulerParamNames[i]);
spooler_log.info("Substitute: "+paramName+"="+paramValue+" with " + schedulerParamNames[i]+"="+schedulerParamValue);
var pattern = new RegExp("\\$\\{?SCHEDULER_PARAM_"+schedulerParamNames[i]+"\\}?","ig");
paramValue = paramValue.replace(pattern,schedulerParamValue);
spooler_log.info( "new value of " +paramName+"="+paramValue);
\}
spooler_task.params.value(paramName) = paramValue;
\}
\}
Substitution of global variables in an order can be carried out in a similar manner.
