Here's an ES2015 solution: // Get all input fields const inputs = document.querySelectorAll('#register input'); // Get only the required ones const requiredFields = Array.from(inputs).filter(input => input.required); // Do your stuff with the required fields requiredFields.forEach(field => /* do what you want */); It should have 5 fields – name, age, education, address and expected salary.
