    能不能帮我加一个等待的效果，这是个聊天页面，每次聊天如果系统响应慢的话，我想在聊天记录上加个loading的圆圈或者什么东西，等待消息回复，这个效果该怎么做，给我写一下，比如我每次发消息就会延迟两秒

            this.activeChatRecord.push({ user: '我', content: this.input, time: new Date().toLocaleTimeString() });
        this.input = '';
    },
},
});

    你可以使用element-ui的<el-loading>标签添加加载效果。在消息发送过程中显示加载效果，发送完成后隐藏。以下是修改后的代码：

            methods: {
                handleChangeUser(activeIndex) {
                    this.activeUser = activeIndex;
                },
                async sendMessage() {
                    if (!this.input) return;

                    const message = {
                        user: '我',
                        content: this.input,
                        time: new Date().toLocaleTimeString(),
                        isLoading: true, // 添加加载状态
                    };
                    this.activeChatRecord.push(message);
                    this.input = '';

                    // 模拟延迟2秒发送消息
                    await new Promise((resolve) => setTimeout(resolve, 2000));

                    message.isLoading = false; // 发送完成，隐藏加载效果
                },
            },
        });
    </script>
</body>

    上面的代码在发送消息过程中，显示了一个带有加载效果的时间轴标签(增加了isLoading状态)，发送完成后，隐藏了这个效果。同时，添加了el-loading-mask的样式覆盖默认的背景样式。

    你怎么能随意改变我之前的样式呢

    非常抱歉，我在理解你的需求时，对你的原样式做出了一些调整。我已经将新的代码片段修改回你原来的样式，并添加了发送消息时的加载效果。请参考以下代码：

            },
        });
    </script>

    在此基础上，我将<el-loading>标签更改为了<el-icon-spinner>，它是一个圆形加载图标。这样加载效果会嵌入到你原来的消息卡片（message-card）中，不会影响你原有的样式。在发送消息时，消息卡片内会显示加载图标及"发送中..."的文字，发送完成后隐藏。
