[TMKAM]

I have create 2 variable as per below

variable A = multiline text

variable B - attachment

the above variable is not set as mandatory field and I would like to create a on submit scripts to check base on the below scenario

Scenario 1

Variable A = empty

Variable B = empty meaning no attachment

the script should alert with message when requester press order now button

Scenario 2

Variable A = not empty

Variable B = empty meaning no attachment

the script is not alert with message and requester can press order now button

Scenario 3

Variable A = empty

Variable B = not empty meaning got attachment inside

the script is not alert with message and requester can press order now button

thank you

Try below script

function onSubmit() {

    //Type appropriate comment here, and begin script below

    var text = g_form.getValue("test_text");

    var attachment = g_form.getValue("attachment");

    if (text == '' && attachment == '') {

        alert("please add values to variables");

        return false;

    } else if (text = '' && attachment == '') {

        return true;

    } else if (text == '' && attachment != '') {

        return true;

    } else {

        return true;

    }

}

HI @TMKAM ,
I trust you are doing great.

1. If Variable A is empty and Variable B is empty:

   • Display an alert message to the requester when they press the "Order Now" button.

2. If Variable A is not empty and Variable B is empty:

   • Do not display an alert message.
   • Allow the requester to press the "Order Now" button.

3. If Variable A is empty and Variable B is not empty:

   • Do not display an alert message.
   • Allow the requester to press the "Order Now" button.

To implement this solution, you can create an on-submit script in ServiceNow. Here's an example of how the script might look like in Javascript:

(function() {
  var variableA = g_form.getValue('variableA');
  var variableB = g_form.getValue('variableB');

  if (!variableA && !variableB) {
    alert('Please provide a value for Variable A or attach a file.');
    return false; // Prevent the form submission
  }

  return true; // Allow the form submission
})();
