Message 消息提示

常用于主动操作后的反馈提示。与 Toast 的区别是后者更多用于系统级通知的被动提醒

组件使用介绍:

1. 注入服务 MessageService

@inject MessageService MessageService
[Inject]
[NotNull]
private MessageService? MessageService { get; set; }

2. 调用其实例 api

await MessageService.Show(new MessageOption()
{
    Content = "这是一条提示消息"
});

从顶部出现,4 秒后自动消失

Demo

通过设置 MessageOptionIcon 属性,更改消息框左侧小图标

Demo

通过设置 MessageOptionShowDismiss 属性,更改消息框右侧出现关闭按钮

Demo

通过设置 MessageOptionShowBar 属性,更改消息框左侧边框样式

Demo

通过设置 MessageOptionColor 属性,更改消息框颜色

Demo

通过设置 MessageService 服务的组件参数,指定已经设置底部显示位置的 Message 组件

Seems like the connection with the server has been lost. It can be due to poor or broken network. Please hang on while we're trying to reconnect...
Oh snap! Failed to reconnect with the server. This is typically caused by a longer network outage, or if the server has been taken down. You can try to reconnect, but if that does not work, you need to reload the page.
Oh man! The server rejected the attempt to reconnect. The only option now is to reload the page, but be prepared that it won't work, since this is typically caused by a failure on the server.
