Jquery steps "destroy" method is removing values given by User

I have a Questionnaire form which is break down in steps by using JQuery steps plugin. In the process of form submission there is a certain point where i need to remove steps. When i use "destroy" JQuery steps method, the values filled in the form are lost.
For example:
<form>
<h3>Form A</h3>
<section>
What is your name?<br/>
<input type="text" value="" name="yourname" />
What is your age group? <br/>
<input type="radio" name="agegroup" value="1" />1-20
<input type="radio" name="agegroup" value="2" />20-40
<input type="radio" name="agegroup" value="3" />40-60
<input type="radio" name="agegroup" value="4" />60+
......
......
<section>
</form>
I am using following steps:
Convert form into Jquery steps
Opening this form in Simple modal dialog.
User fill this form and close modal dialog.
I am using "destroy" jQuery steps method after closing dialog.
When user re-open simple modal dialog again then i am converting this form into JQuery steps. At that point user see that all filled values in the form are lost.
The problem is at the 4th step. User have filled form at 3rd step. When i converted in back to original HTML, values given by user are lost.
Expected values at 4th step
<h3>Form A</h3>
<section>
What is your name?<br/>
<input type="text" value="Ishwar Lal" name="yourname" />
What is your age group? <br/>
<input type="radio" name="agegroup" value="1" />1-20
<input type="radio" name="agegroup" value="2" selected='selected' />20-40
<input type="radio" name="agegroup" value="3" />40-60
<input type="radio" name="agegroup" value="4" />60+
......
......
<section>
but output is:
<h3>Form A</h3>
<section>
What is your name?<br/>
<input type="text" value="" name="yourname" />
What is your age group? <br/>
<input type="radio" name="agegroup" value="1" />1-20
<input type="radio" name="agegroup" value="2" />20-40
<input type="radio" name="agegroup" value="3" />40-60
<input type="radio" name="agegroup" value="4" />60+
......
......
<section>
I need to remove JQuery steps from from with filled values. I have read JQuery documentation but not found any idea about this.

I think that you must to store data before you destroy the component. When you destroy a component it is destroyed, nothing else what to do.
If you store the data , then destroy object, and then initialize object with the data you stored. You can store in an array/object/variable, or you can store in sessionStorage / localStorage for use in other pages.

Cloning forms with radio buttons

Cloning forms in jQuery, for example to create an RSVP option on a guest list with multiple people, is relatively simple.
$(selector).clone().insertAfter(selector:last)
It's relatively easy with inputs as well, offering the ability to copy methods or properties by passing true to the clone() method. To cope with multiple inputs you can append [] to the end of your input names:
<input type="text" name="email_address[]"/>
However this becomes more complicated with <input> elements of type radio, as you would usually use these to denote a choice:
<input type="radio" name="choice" value="1"/> <input type="radio" name="choice" value="2"/>
Adding the square bracket syntax further confuses things, as there are still multiple values, and some browsers may now allow different selections:
<label>Person:</label> <input type="radio" name="choice[]" value="1"/> <input type="radio" name="choice[]" value="2"/>
<label>Person:</label> <input type="radio" name="choice[]" value="1"/> <input type="radio" name="choice[]" value="2"/>
How can we solve this in a way which allows easy cloning whilst not making radio buttons hard to parse on the back end?

Turns out this can be achieved with a little bit of RegEx fun!
Firstly add a numeric value to your first input element:
<input type="radio" name="choice[0]" value="1"> <input type="radio" name="choice[0]" value="2">
Now in your JavaScript
$(selector).clone().insertAfter(selector:last)
.find('input[type="radio"]').each(function(){
var name=$(this).attr('name');
$(this).attr('name',name.replace(/([0-9]+)/g,1*(name.match(/([0-9]+)/g))+1));
});
Which creates a simple increment in numbers for each element in line with their siblings.

Preventing radio buttons from being clicked completely

This has been bugging me for a while now. I'm trying to prevent users from clicking on a radio button depending if the user has the access to do so. The first solution was to do the following:
Without disabled
<input type="radio" name="my_radio1" id="abc1" value="5">
<input type="radio" name="my_radio1" id="abc2" value="0">
<input type="radio" name="my_radio1" id="abc3" value="1" checked>
With disabled with pre-selection
<input type="radio" name="my_radio2" id="abc1" onclick="return false;" value="5">
<input type="radio" name="my_radio2" id="abc2" onclick="return false;" value="0">
<input type="radio" name="my_radio2" id="abc3" onclick="return false;" value="1" checked>
With disabled and no pre-selection
<input type="radio" name="my_radio3" id="abc1" onclick="return false;" value="5">
<input type="radio" name="my_radio3" id="abc2" onclick="return false;" value="0">
<input type="radio" name="my_radio3" id="abc3" onclick="return false;" value="1">
As shown here: http://jsfiddle.net/93CqR/6/
This works great for radio buttons ALREADY checked but doesn't work for boxes that haven't been checked (as shown in example 3 above). Are there any known workarounds to this?
Chrome and IE behave differently with this

You should add a 'disabled' attribute to the ones not selectable. You don't really need the javascript.
see http://jsfiddle.net/Ma6TA/
<input type="radio" name="my_radio2" id="abc1" value="5" disabled>
<input type="radio" name="my_radio2" id="abc2" value="0" disabled>
<input type="radio" name="my_radio2" id="abc3" value="1" checked disabled>
Update I don't know the actual use case here, but if you aren't already, the actual check for this should be done on the server. Disabling or hiding the input from the user with javascript will enhance the UX, but a nefarious user could get around these things.

I would use javascript to show/hide the elements that users have access to. For 2 reasons.
1) It's a better user experience if they can only see the form elements they can manipulate.
and more importantly
2) a disabled form field WILL NOT show up in the post/get array. I've had issues with this in the past and it is a very frustrating problem if you don't know why you're fields aren't coming through.
it could be as simple as wrapping js code in a php conditional ie...
<?php if($userCantSeeThese): ?>
<script>
$('.classOfElementsUserShouldntSee').hide();
</script>
<?php endif; ?>

Bootstrap 3: wizard with form validation

I want to create a wizard with a form validation with bootstrap. I use the Twitter Bootstrap Wizard Plugin from http://vadimg.com/twitter-bootstrap-wizard-example/. It uses jQuery Validate Plugin.
My problem is now that the validation of radio buttons does not work. I can skip through the "tabs" even if no radio button is checked.
Has anyone an idea what I've made wrong?
This is my Javascript-Code:
<script>
$(document).ready(function() {
var $validator = $("#commentForm").validate();
$('#rootwizard').bootstrapWizard({
'tabClass': 'nav nav-pills',
'onNext': function(tab, navigation, index) {
var $valid = $("#commentForm").valid();
if(!$valid) {
$validator.focusInvalid();
return false;
}
}
});
window.prettyPrint && prettyPrint()
});
</script>
My input elements look like this here:
<div class="btn-group" data-toggle="buttons">
<label class="btn btn-primary">
<input class="required" id="question21" name="question2" required="" type="radio"> 1</label>
<label class="btn btn-primary">
<input id="question22" name="question2" type="radio"> 2</label>
<label class="btn btn-primary">
<input id="question23" name="question2" type="radio"> 3</label>
<label class="btn btn-primary">
<input id="question24" name="question2" type="radio"> 4</label>
<label class="btn btn-primary">
<input id="question25" name="question2" type="radio"> 5</label></div>
Here the entire code of the site:

Thanks in advance!

You've declared the required rule twice in your HTML markup...
<input class="required" id="question21" name="question2" required="" type="radio">
1) By class: class="required" is declaring the name="question2" radio button set as required.
2) By HTML5 attribute: required="" is declaring the name="question2" radio button set as not required.
Apparently the jQuery Validation plugin gives precedence to the HTML5 attribute.
You only need to use one method of declaring the rule. Use class or HTML5 attribute, not both. If you decide to keep the HTML5 attribute, then use required="required".
EDIT:
Quote OP's Comment:
"... But either class="required" or required="required" works :-( Do you have another idea?"
Did you mean to say "neither" of those works? Both of those work perfectly fine, as well as another method...
Rule declared by class="required": http://jsfiddle.net/MHWmx/
Rule declared by required="required": http://jsfiddle.net/MHWmx/1/
Rule declared within .validate(): http://jsfiddle.net/MHWmx/2/
Otherwise, there's a problem in code you have not shown.

Dynamically change input id with value - input type=range

I'm making a phone gap query mobile iOS app for course evaluation at my uni. This app primary function will be a form that in it's original form uses radio buttons where each value also has a corresponding id - e.g.
<input name="q10" id="1" value="1" type="radio" />
<input name="q10" id="2" value="2" type="radio" />
<input name="q10" id="3" value="3" type="radio" />
<input name="q10" id="4" value="4" type="radio" />
<input name="q10" id="5" value="5" type="radio" />
<input name="q10" id="6" value="6" type="radio" />
But radio buttions aren't that intuitive on iOS devices so I'm using input type range instead.
This works great for changing the value between 1 and 6 but the problem is that one only specifies one id for the whole input, not one id per value.
<input type="range" name="q10" id="q10" value="0" min="0" max="6" />
Is there a way to change the id with the value? I think this should be doable through JavaScript but I lack the know-how. I also cannot change the way the database is set up (requiring both id and value) as this database belongs to the university's IT-department.

You can use the change event
<input type="range" onchange="this.id=this.value" name="q10" id="q10" value="0" min="0" max="6" />
Working example here - http://jsfiddle.net/aVHm8/
Note: I always feel uneasy about changing the ID of a DOM element .. perhaps you should investigate better options to resolve your issue

The database can't know what the id is unless you use JavaScript to send it to the server (standard form submission sends the name and the value). In which case find the bit of JS that pulls out the ID and just send the value twice instead.
