        <!--模态框 弹出框-->
        <!-- 
        用法：
        您可以切换模态框（Modal）插件的隐藏内容：
            1.通过 data 属性：在控制器元素（比如按钮或者链接）上设置属性 data-toggle="modal"，同时设置 data-target="#identifier" 或 href="#identifier" 来指定要切换的特定的模态框（带有 id="identifier"）。
            2.通过 JavaScript：使用这种技术，您可以通过简单的一行 JavaScript 来调用带有 id="identifier" 的模态框：
        $('#identifier').modal(options)
         -->
        <div role="dialog" class="modal fade bs-example-modal-sm my-class" id="layer">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal">
                            <span>&times;</span>
                        </button>
                        <h4 class="modal-title">确认删除么?---{{msg}}</h4>

                    <div class="modal-body text-right">
                        <button data-dismiss="modal" class="btn btn-primary btn-sm">取消</button>
                        <button data-dismiss="modal" class="btn btn-danger btn-sm" v-on:click="deleteMsg(nowIndex)">确认</button>
