Trouble with Custom Scope UI Action Script for CSV File Creation

[senon]

Hi Experts.

I want to use a UI action to create a CSV file containing all the field labels and field values recorded in the current record and attach it to the record.

I understand that this UI action is created with a custom scope and therefore has scripting limitations.

I created the following script, but it is not working.

// This script is designed to be used as a UI action in ServiceNow.
// It retrieves the field labels and values of the current record and creates a CSV file for the record.
// The application scope is custom, so it is not global.

var table = "<table_name>";
var recordId = current.sys_id;
var output = "";

var elementLabelArr = current.getElements(); 
var elementValueArr = current.getElements();

var fldsLabel = [];
var fldsValue = [];

// Move the field names and values into JavaScript Arrays...
for (var i = 0; i < elementLabelArr.length; i++) {
    // Push the field labels into the array
    fldsLabel.push(elementLabelArr[i].getLabel());
    // Push the field values into the array
    fldsValue.push(elementValueArr[i].getDisplayValue());
}

// Prepare the CSV output
output += fldsLabel.join(",") + "\n";
output += fldsValue.join(",") + "\n";

// Call the function to write the CSV as an attachment for the current record
writeAttachmentFile(output);

// Function to write the CSV file as an attachment
function writeAttachmentFile(data) {
    // Create a new instance of GlideSysAttachment
    var attachment = new GlideSysAttachment();
    // Write the CSV data as an attachment for the current record
    var attachmentRec = attachment.write(table, recordId, "export.csv", "text/csv", data);
}

Am I on the right track?
Please help me if you have a problem with this script and can help me figure it out.

Best Regards.

Hi @senon 

basically you only have to copy and modify the code given in the examples of the API documentation.

The following script is doing the job:

var fldsLabel = [];
var fldsValue = [];
var fields    = current.getFields();
var output    = '';

for (var i = 0; i < fields.size(); i++) {
  var glideElement = fields.get(i);

  fldsLabel.push(glideElement.getLabel());
  fldsValue.push(glideElement.getDisplayValue()); 
}

// Prepare the CSV output
output += fldsLabel.join(",") + "\n";
output += fldsValue.join(",") + "\n";

// Create a new instance of GlideSysAttachment
var attachment = new GlideSysAttachment();
// Write the CSV data as an attachment for the current record
var attachmentRec = attachment.write(current, "export.csv", "text/csv", output);

Hi, thanks for your reply.

This script is available in global scope, but I need to realize it in custom scope.

var fields = current.getFields();

The above script is not available in custom scope.
Is there any way to realize it in custom scope?

Hi @senon 

again, a look into the API document is helpful. There is a helper script include which does the job in global as well as in custom scopes. The modified script now looks as follows:

var fldsLabel = [];
var fldsValue = [];
var fields    = new global.GlideRecordUtil().getFields(current);
var output    = '';

for (var i = 0; i < fields.length; i++) {
  var glideElement = current.getElement(fields[i]);

  fldsLabel.push(glideElement.getLabel());
  fldsValue.push(glideElement.getDisplayValue()); 
}

// Prepare the CSV output
output += fldsLabel.join(",") + "\n";
output += fldsValue.join(",") + "\n";

// Create a new instance of GlideSysAttachment
var attachment = new GlideSysAttachment();
// Write the CSV data as an attachment for the current record
var attachmentRec = attachment.write(current, "export.csv", "text/csv", output);
