使用 jquery 依次验证多个 forms

Question

I am trying to validate various forms in steps. I have 3 forms. I am able to get the first form to show and the rest to hide. When I click on "next" to show next form, the first form disappears, but the next form will not show up. Please advice what I am doing wrong. Here is my code HTML

<!-- Progress Bar -->
            <ul id="progressBar">
                <li class="active">Account Basics</li>
                <li>Account Details</li>
                <li>Final Steps</li>
            </ul>
            <!--  <form class="form-horizontal" method="post" name="clientRegistration" action="" id="clientRegistration" data-validation="server" data-validation-url="processUser.php">-->

Thought it would help to provide url of what I am trying to emulate, I changed the code from 1 form and 3 legends to 3 forms each with their own legend. jsfiddle url: jsfiddle url of what I want to achieve Any and all help would be appreciated. Thanks.

Answer 1

Try to point out the issue with your question from comment but I guess there is not enough space to summarize it.

What you intended to do is considered as a bad practice and abuse the usage of form. Each form generally has its own submit button and holds its own task (or business logic) so data can be sent to server for processing once you hit the submit button. And you would expect refresh and redirect your page to somewhere else upon submission . That's why we always want to have one form for each page and prevent duplicated submission.

If you noticed the url provides, data from all 3 panels are contained in just one account-create form. All data will be sent to server and validated at one time. There are many buttons but button types are different. If something is broken during the process, user can always restart from the beginning.

In short, form -> server.

If you separated them to three forms (even put each form into its own page), it's messy with a lot of security hole.

form1->server (pass the validation, account is created), form2 somehow failed due to any reasons(internet issues,etc). Now users has trouble to go back to step1 because the account is created, whether you have to create another block to solve this messy completely. Not to mention you are trying to put three forms with same intention within one page, it's unsalvageable on your case.
