JQuery and Radio Button array

Question

Does anyone know how to go about validating the form that contains a radio button array(using JQuery)?

I have something like this...

6<input type="radio" name="answer[5]" value="6"> 
5<input type="radio" name="answer[5]" value="5"> 
4<input type="radio" name="answer[5]" value="4"> 

6<input type="radio" name="answer[13]" value="6"> 
5<input type="radio" name="answer[13]" value="5"> 
4<input type="radio" name="answer[13]" value="4">

The indicies are not necessarily in order. The questions are dynamic.

Is there a way to iterate through these answers in jquery??

Welcome to SO. Your question is too broad and will probably be put On Hold. Do some research into possible solutions, and come back with more specific questions (and your code). — isherwood

Here's how I would do it:

function validate(){
    $('input [type=radio]').each(function(){
        if ($(this).val() !== 'something valid') return false;
    }
    return true;
}

if( !validate()) alert('invalid');

How do you want to iterate through them? If you want to iterate through them all, you can just use the .each function such as:

$('input:radio[name=answer[]]').each(function(data){
   //Do something here
});

You could use jQuery to create subsets of radiobuttons accordingly

$('input [name="answer[5]"]);

This will gather all inputs that have name-attribute with value "answer[5]". After that you can iterate through that subset like this

$('input [name="answer[5]"])[i].val(); // or any other attribute you wish to get from query.
