javascript - 如何更改div中的可见按钮？

Question

大家好，我有一些代码:

<div class="a">
    <div class="btn-group">
        <button class="btn make-editable" data-name="GlobalCorrelationMatrix" data-action="edit-row">Edit</button>
        <button class="btn make-approve" data-name="GlobalCorrelationMatrix" data-action="approve-row">Save</button>
        <button class="btn make-close" data-name="GlobalCorrelationMatrix" data-action="discard-row">Close</button>

    </div>
</div>
<div class="b">
    <div class="btn-group">
        <button class="btn make-editable" data-name="GlobalCorrelationMatrix" data-action="edit-row">Edit</button>
        <button class="btn make-approve" data-name="GlobalCorrelationMatrix" data-action="approve-row">Save</button>
        <button class="btn make-close" data-name="GlobalCorrelationMatrix" data-action="discard-row">Close</button>

    </div>
</div>

当我使用 $("button.btn.approve").addClass("disabled"); div a 和 div b 中的按钮被禁用。如何仅从 div a 禁用按钮批准？

如果点击按钮，只想给同组的按钮添加类？

如果是，请执行此操作:

$('.btn-group .btn').click(function(){
    $(this).parent().children('.btn').addClass('disabled');
});

.disabled {
  color: #bbb;
}
