Dynamically retrieving the Labels of fields on the Current record

I've been struggling with this one for a little while now, and was hoping to find some help here.

I have a business rule on a table in a Scoped App which is running some functions to look at a related record to retrieve a comma separated list of field values, then use those field values elsewhere (to programatically create a text block for a child Incident record for example).

Current Record -> Related Configuration record (contains a comma separated list of field values called "additional_field_1")

//construct the text for all the display fields in the Subcategory Map string field
var displayFields = subCatMap.additional_field_1.toString();                             // Grab the Display Field from the Mapping table and split into array.
var fieldArray = displayFields.split(",");
for (var a=0; a< fieldArray.length; a++){                                                                     // use the field array to create a loop
var currentField = fieldArray[a];
fieldText += current.getElement('currentField').getLabel(); +": "+ current.getValue(currentField)+"\n";             // for each field in the loop, capture the Label and value with a Line Break

The line "current.getElement('currentField').getLabel();" doesn't get me what I want - I think at the moment it errors out.

I've tried "current.getLabel('currentField');' but this only gives me the label of the current record type - not the field that is named by my "currentField" string

Any idea how i might be able to ask ServiceNow to just give me current.currentField.getLabel() where currentField is dynamically set earlier in the loop?

Hi Kevin,



Could you please try the below code,



  1. var displayFields = subCatMap.additional_field_1.toString();                          
  2. var fieldArray = displayFields.split(",");  
  3. var fieldText = '';
  4. for (var a=0; a < fieldArray.length; a++){                                                                    
  5. var currentField = fieldArray[a];  
  6. fieldText += current.getElement(currentField).getLabel() + " : "+ current.getValue(currentField)+"\n";
  7. }

Hope this helps you Kevin.

Thanks Anudeep,



Looks like it was a dumb syntax error - used '' when I shouldn't have.   Shawn's solution was a little more elegant again.



Here's what worked for me: 



//construct the text for all the display fields in the Subcategory Map string field

var displayFields = subCatMap.additional_field_1.toString();                                     // Grab the Display Field from the Mapping table and split into array.

var fieldArray = displayFields.split(",");

for (var a=0; a< fieldArray.length; a++){                                                                           // use the field array to create a loop

var currentField = fieldArray[a];

fieldText +="\n"+ current[currentField].getLabel() +": "+ current.getValue(currentField)+"\n";                   // for each field in the loop, capture the Label and value with a Line Break

}
