Hello,

I have a js function that help me calculate a value based on a eForm field value. I want that function on a button, so it puts that calculated value on another field in the form.

It's first time I m using Javascript and I can't get this done, basically the code doesn't do something when I press the button. ( I assigned the function to the button )

That's the code:

/////

function calculateAmount(number) {
  // Round the number to one decimal place
 
                
  var roundedNumber = Math.round(number * 10) / 10;

  // Get the integer and decimal parts of the rounded number
  var integerPart = Math.floor(roundedNumber);
  var decimalPart = roundedNumber - integerPart;

  // Multiply the integer part by 100 lei
  var amount = integerPart * 100;

  // Add the additional amount based on the decimal part
  if (decimalPart >= 0.1 && decimalPart <= 0.5) {
    amount += 50;
  } else if (decimalPart > 0.5 && decimalPart <= 0.9) {
    amount += 100;
  }

  return amount;
  

}

var options = {};
options.fieldId = 'Diferentadezilenplus1cheltronnnx';

eFormHelper.getFieldValue(options, function (result) {
  if (result.isSuccess) {
    var fieldValue = parseFloat(result.data);
    var amount = calculateAmount(fieldValue);

    options.fieldId = 'ValDiurnacalculataautomatcheltronx';
    options.value = amount.toString();

    eFormHelper.setFieldValue(options, function (result) {
      if (result.isSuccess) {
        console.log("Amount calculated and set successfully.");
      } else {
        console.log(result.error);
      }
    });
  } else {
    console.log(result.error);
  }
});

  Hi Ciprian,

  My analysis of your code revealed a syntactical error where you missed wrapping the eFormHelper methods in a separate function.

  function calculateAndSetAmountField() {

  var options = {};
  options.fieldId = 'Diferentadezilenplus1cheltronnnx';

  eFormHelper.getFieldValue(options, function (result) {
    if (result.isSuccess) {
      var fieldValue = parseFloat(result.data);
      var amount = calculateAmount(fieldValue);

      options.fieldId = 'ValDiurnacalculataautomatcheltronx';
      options.value = amount.toString();

      eFormHelper.setFieldValue(options, function (result) {
        if (result.isSuccess) {
          console.log("Amount calculated and set successfully.");
        } else {
          console.log(result.error);
        }
      });
    } else {
      console.log(result.error);
    }
  });

  }

  Please ensure that the function wrapped for the eFormHelper methods (i.e. calculateAndSetAmountField()) is attached to the click event of the button in order to achieve the desired functionality.
