Learn Form Validation by Building a Calorie Counter - Step 74

[cmuraya12]

Tell us what’s happening:

I have used use return to end the function execution but it doesn’t seem to work. Any ideas of what I’m doing wrong?

Your code so far

The challenge seed code and/or your solution exceeded the maximum length we can port over from the challenge.

You will need to take an additional step here so the code you wrote presents in an easy to read format.

Please copy/paste all the editor code showing in the challenge from where you just linked.

function calculateCalories(e) {
  e.preventDefault();
  isError = false;

  const breakfastNumberInputs = document.querySelectorAll('#breakfast input[type=number]');
  const lunchNumberInputs = document.querySelectorAll('#lunch input[type=number]');
  const dinnerNumberInputs = document.querySelectorAll('#dinner input[type=number]');

  const exerciseNumberInputs = document.querySelectorAll('#exercise input[type=number]');

  const breakfastCalories = getCaloriesFromInputs(breakfastNumberInputs);
  const lunchCalories = getCaloriesFromInputs(lunchNumberInputs);
  const dinnerCalories = getCaloriesFromInputs(dinnerNumberInputs);
  const snacksCalories = getCaloriesFromInputs(snacksNumberInputs);

  const budgetCalories = getCaloriesFromInputs([budgetNumberInput]);

if(isError){
  isError=true;
  return;
}
}

Welcome to the forum @cmuraya12

The function should only contain the keyword.

isError=true; is assigning a Boolean value. It is also not needed.

Happy coding

In your provided code snippet, it seems you are trying to use the return statement to exit the calculateCalories function if an error (isError ) is encountered. However, there are a couple of issues:

function calculateCalories(e) {
e.preventDefault();

const breakfastNumberInputs = document.querySelectorAll(‘#breakfast input[type=number]’);
const lunchNumberInputs = document.querySelectorAll(‘#lunch input[type=number]’);
const dinnerNumberInputs = document.querySelectorAll(‘#dinner input[type=number]’);
const snacksNumberInputs = document.querySelectorAll(‘#snacks input[type=number]’);
const exerciseNumberInputs = document.querySelectorAll(‘#exercise input[type=number]’);
const budgetNumberInput = document.querySelector(‘#budget input[type=number]’); // Assuming budgetNumberInput is defined somewhere

const breakfastCalories = getCaloriesFromInputs(breakfastNumberInputs);
const lunchCalories = getCaloriesFromInputs(lunchNumberInputs);
const dinnerCalories = getCaloriesFromInputs(dinnerNumberInputs);
const snacksCalories = getCaloriesFromInputs(snacksNumberInputs);
const exerciseCalories = getCaloriesFromInputs(exerciseNumberInputs);
const budgetCalories = getCaloriesFromInputs([budgetNumberInput]);

// Check for errors
let isError = false;
// Example of a condition that sets isError to true
if (breakfastCalories < 0 || lunchCalories < 0 || dinnerCalories < 0 || snacksCalories < 0 || exerciseCalories < 0 || budgetCalories < 0) {
isError = true;
}

// If there’s an error, return to exit the function
if (isError) {
return;
}

// Continue with the rest of your function if no errors occur
}
In this revised version, I’ve added a condition to check for errors (arbitrarily assuming that a calorie value less than 0 indicates an error), and if an error is detected, the function returns, effectively stopping further execution.
