Step by step guide to implementing form step validation in a multi-step jQuery form with radio buttons

I have implemented the sample code provided in this link, with the addition of 2 extra form steps:

LINK TO SAMPLE FORM

My form consists of radio buttons (2 per page) instead of text boxes. How can I ensure that each form page is validated so that the form does not advance if no radio button has been selected? Ideally, I would like to provide feedback to the user prompting them to make a selection if none has been made. Currently, the form will advance even if no input has been provided, as demonstrated in the link above.

Thank you in advance!

Answer №1

Within the $(".next").click function, just after setting the next_fs variable with 

next_fs = $(this).parent().next();
, you can implement the following logic:

If the current frame does not have any radio buttons checked (current_fs.find('input:radio:checked').length == 0), 
// Add error message handling here
return false;

This code snippet checks for any checked radio buttons in the current frame and prevents the button click event if none are found. You can also display an error message before returning false.

Although I haven't personally tested this solution by recreating it, I believe it should be helpful. Please feel free to reach out if you encounter any issues with implementation.

Answer №2

Perhaps considering implementing the "required" attribute could be beneficial in this situation. Take a look at this example:

input type = "text" placeholder = "Enter Name" required
