Example

This example does the following:

• Searches the probsummary table for any incident record you define in the search variable
• Displays the new incident record as a text string
• Converts the action field into a JavaScript array
• Adds an item to the end of the array and displays the total number of elements in the array
• Removes an item from the beginning of the array and displays the array item removed

This example requires the following sample data:

• A valid value for the number field (for example, "IM1010")
• An incident record with an action field value (for example, "IM1010")

var incidentID;

function findIncident( id )
{
 print( "Searching for Incident record: " + id + "..." );
 var incidentFile = new SCFile( "probsummary" );
 var rc = incidentFile.doSelect( "number=\"" + id + "\"" )
 if ( rc == RC_SUCCESS )
 {
  print( "Success. found Incident record:\n" + incidentFile.getText() );
  print( "Converting the action field to a JavaScript array..." );
  var a = incidentFile.action.toArray();
  print( "The action field array contains the following: " + a );
  print( "Pushing new array entry..." );
  var addOne = a.push( "First array item" );
  print( "The number of items in the array are: " + addOne );
  print( "The action field array contains the following: " + a );
  print( "Shifting array one entry..." );
  var removeOne = a.shift();
  print( "The array item removed was: " + removeOne );
  print( "The action field array contains the following: " + a );
  return incidentFile;
 }
 else
 {
  print( "Could not find Incident record. " + RCtoString( rc ) );
  return null
 }
}

incidentID = "IM1010";
findIncident( incidentID );
