Radio Buttons

Hi Folks,

Does anyone know how to change a background of label when a radio buttons is clicked? I have been messing about with javascript but haven't gotten anywhere.

Pretty much when the user clicks on the radio buttons I want the background to change to white with a left border of 1px solid #000.

I would appreciate any help on this, I have been going around in circles.

Thanks,

Mary

Given the following markup:

<label>
    <input type="radio" name="toppings" value="green peppers"/>
    Green Peppers
</label>

<label>
    <input type="radio" name="toppings" value="onions"/>
    Onions
</label>

<label>
    <input type="radio" name="toppings" value="pepperoni"/>
    Pepperoni
</label>

You could handle it with the following javascript:

    $('input[type=radio]').change(function(){
        $('label').removeClass('selected');
        $(this).parents('label').addClass('selected');
    });

Then just set your styles in label.selected.

Obviously this is the most basic of examples to achieve what you're looking for, but hopefully it'll be a good jumping off point for you to get started.

EDIT: Here's the above example in JSFiddle: http://jsfiddle.net/7vypL1q6/

That's a great help, Thank You. I haven't delved enough into javascript yet to get anything going smoothly.

Thanks again.
