How to make a choice of one of the group elements of mixed inputs?

I have following code:

<div class="item">
  <input type="radio" name="group1" value="value1">Value1</input>
  <input type="radio" name="group1" value="value2">Value2</input>
  <input type="radio" name="group1" value="value3">Value3</input>
  <textarea name="group1"></textarea>
</div>
  <div class="item">
  <input type="radio" name="group2" value="value1">Value1</input>
  <input type="radio" name="group2" value="value2">Value2</input>
  <input type="radio" name="group2" value="value3">Value3</input>
  <textarea name="group2"></textarea>
</div>

I think about: when we click on textarea, radiobuttons should lost checked atribure. Like:

$('.item textarea').on('click', function(){
  $($(this).parent + 'input[type="radio":checked]').each(function(){
    $(this).checked = false;
  });
});

But it not work. I think the problem with parent object. Thanks.

There are many problems in your variant. First, there is a problem in your selector construction: $($(this).parent + 'input[type="radio":checked]'). Here you mix jQuery object with the string selector which is not correct. Moreover, parent element is taken with method parent() but not a property. Then, jQuery object doesn't have checked attribute.

Taking into consideration all the problems described we can get this workable code:

$('.item textarea').on('click', function() {
    $(this).siblings(":radio").prop("checked", false);
});

By the way, if you need to uncheck all radios when the user enters textarea not only using mouse click but using keyboard, you can use focus event instead.
