                                        <label class="btn btn-primary">
                                            <input type="radio" name="type"
                                                   value="h"> 2核4G
                                        </label>
                                    </form>
                                </div>

• 打开浏览器console,输入:

$('input[name="type"]:checked').val();

就可以显示选中的value值.

data-toggle="buttons"这个是把样式设置成了按钮样式.
