SweetAlert 弹窗组件

模态对话框，多用于动作过程中进行询问后继续，或者显示执行结果

基础用法

通过注入服务调用 Swal 来弹出一个对话框

Demo

成功

失败

警告

提示

疑问

设置显示内容

通过设置 Title Content 用于显示弹窗标题与内容

Demo

自定义按钮

通过设置 ButtonTemplate 自定义弹窗内按钮

Demo

显示自定义组件

通过设置 Component 弹窗内容为自定义组件

Demo

模态对话框

通过调用 await SwalService.ShowModal 方法弹出模态框，点击弹窗内按钮关闭弹窗后，后续代码继续执行

Demo

本示例代码通过调用 await SwalService.ShowModal 方法弹出模态框，只有关闭弹窗后，后续代码才继续执行

IsConfirm 参数表示弹窗为确认窗口，自动生成 取消 确认 两个按钮

var ret = await SwalService.ShowModal(op);

// ShowModal 返回后下面代码才执行
Trace?.Log($"模态弹窗返回值为：{ret}");

显示 Footer 信息

通过设置 FooterTemplate 自定义 Footer 模板

Demo

参数 ShowFooter 默认为 false 不显示页脚模板，需要显示设置为 true

自动关闭功能

通过设置 IsAutoHide Delay 属性，自定义自动关闭时间

Demo

参数 IsAutoHide 默认为 false 不启用自动关闭功能
参数 Delay 默认为 4000 毫秒

小技巧

需要在使用本组件的页面中内置 SweetAlert 组件，或者在 MainLayout 主布局组件中内置，示例代码如下：

<SweetAlert />

Attributes

@page "/swals"
