Ensure that all necessary fields are filled out by applying 'required' validation to each one

In the form I'm working with, there are various input elements like text boxes, date pickers, and drop downs. My goal is to make all other fields required once a value is entered in any field. For example, if a value is entered in a text box, then all other fields should become mandatory. The same applies if a date is selected, making all text boxes and drop downs mandatory as well. While I found a solution on Stack Overflow for setting validity on multiple inputs, it only worked for text boxes and not for drop downs and date pickers.

Thank you.

Answer №1

To ensure that all elements have the required attribute in JavaScript, you could iterate through each element and assign the required="required" attribute to it.

For example, you can use this code snippet:

var elements = document.getElementsByClassName("elements");
for (let j = 0; j < elements.length; j++) {
  elements[j].setAttribute("required", "required");
}
