How to get value from checkbox

I am using checkbox with style but I am not getting its value, First I have used simple checkbox which was working but I have changed its style now I am not getting its value.

<div class="radio red icheck">
    <label>                                                      
        <input type="radio" name="status" onclick="alert('dlfkjdkl')" value="1" class="status_enable" checked>
        Enable
    </label>
</div>
