请帮助我防止Bootstrap单选按钮过早提交表单（使用Javascript？）

Question

My process:

1. First I designed a signup form for my website using Bootstrap
2. Then, I created a signup form using MailChimp, so I can track and contact my signups
3. I then generated the embed form HTML markup, and combined the two

The issue:

The part that is breaking the form is that the Bootstrap radio button toggle uses input type="button" and the MailChimp form I am trying to map it to uses type="radio".

If I don't use type="radio", the submission works but when I check the information on my subscribers in MailChimp, I am missing data from that part of the form on.

If I use type="radio", the form prematurely submits when the user tries to use the toggle button, so basically the form submits before they can finish filling out the rest of the form.

JSFiddle Demo of the issue is here: http://jsfiddle.net/halsey/qwPzy/9/

The solution?

I am aware of threads like this , which say you will need to override this behavior with javascript, but I can't find an example of how to do this.

I'm sure this is embarrassingly easy but I am having trouble locating resources to help me learn how to fix this. Thanks in advance for any help you can provide.

Footnote

StackOverflow is preventing me from linking to JSFiddle without embedding code. I would encourage you to use the link above, but my broken attempt at embedding the code is below. Apologies for the weird formatting but I am having trouble embedding the code in one chunk - I am a StackOverflow beginner.

Answer 1

Have you tried putting an "onsubmit" on the form and running thru a function to determine testing?

ala

<form action="http://foorder.us6.list-manage1.com/subscribe/post?u=81c3da3b3ebbf564cf50a78ff&amp;
    id=f16451f556" method="post" id="mc-embedded-subscribe-form" 
    name="mc-embedded-subscribe-form" class="validate" target="_blank" 
    onsubmit="return checkValidity(this);">

and in your js code:

function checkValidity(form){
  if(){
       // return false <-- doesn't submit
      }
  }

Answer 2

So this JSFiddle that I found on the Bootstrap Github worked for me: http://jsfiddle.net/charettes/SauLj/

HTML:

<div class="btn-group">
<input type="radio" name="radios" id="radio_1" />
<label class="btn" for="radio_1">Radio one</label>
<input type="radio" name="radios" id="radio_2" />
<label class="btn" for="radio_2">Radio two</label>
<input type="radio" name="radios" id="radio_3" />
<label class="btn" for="radio_3">Disabled radio three</label>

CSS:

    .btn-group > input {
    display: none;
}

.btn-group input:first-child + .btn {
     /* This is an actual copy/paste of the .btn-group .btn:first-child style */
    border-bottom-left-radius: 4px;
    border-top-left-radius: 4px;
    margin-left: 0;
}

input:checked + label.btn {
    /* This is an actual copy/paste of the .btn:active style */
    background-color: #E6E6E6;
    background-image: none;
    box-shadow: 0 2px 4px rgba(0, 0, 0, 0.15) inset, 0 1px 2px rgba(0, 0, 0, 0.05);
    color: rgba(0, 0, 0, 0.5);
    outline: 0 none;
}

input[disabled] + label.btn {
    /* This is an actual copy/paste of the .btn:disabled style */
    background-color: #E6E6E6;
    background-image: none;
    box-shadow: none;
    cursor: default;
    opacity: 0.65;
}
