-//自定义背景颜色/透明度
-this.$toast.text('自定义背景颜色/透明度',{
-    bgColor:'rgba(50, 50, 50, 0.9)'
-});
-
-//自定义class
-this.$toast.text('自定义class',{
-    customClass:'my-class'
-});
-
-//自定义Icon

-});
+Toast.warn(msg);
 ```
-## 共享实例
 
-如果不设置id，多个Toast将默认拥有相同的id，**它们将共享一个实例**（loading类型与其他类型实例不共享），新的内容和设置将取代旧的，多个Toast不能同时出现。如果不需要共享实例，可以给其设置id。
+### 动态更新
 
 ```javascript
-//二者id不同，不会共享一个实例
-this.$toast.success(msg,{
-    id:123
-});
-
-this.$toast.text(msg,{
-    id:321,
-    duration:4000
-});
+Toast.loading(msg, { duration: 0, id: 'test' });
+setTimeout(() => {
+  Toast.success('加载完成', { id: 'test', duration: 2000 });
+}, 2000);
 ```
 
-## 支持在JS模块中导入使用
+##¥ 支持在JS模块中导入使用
 ```javascript
 import { Toast } from "@nutui/nutui";
-
 Toast.text('在js模块中使用');
 // 返回实例，可以手动调用实例中的hide方法关闭提示
 const toast = Toast.loading('在js模块中使用');
 toast.hide();
 ```
 
-## 修改默认配置
-
-通过**Toast.setDefaultOptions**函数可以全局修改 Toast 的默认配置，**值得注意的是，loading无法支持默认配置的修改和重置**。
-
-```js
-// 更改所有Toast展示时长设置为5000毫秒
-Toast.setDefaultOptions({
-    duration: 5000,
-    coverColor: "rgba(0, 0, 0, 0.2)",
-    closeOnClickOverlay: true,
-    cover: true
-});
-
-// 重置所有 Toast 的默认配置
-Toast.resetDefaultOptions();
-
-// 更改所有文字提示默认设置
-Toast.setDefaultOptions("text", {
-    size: "large",
-    cover: true,
-    coverColor: "rgba(0, 0, 0, 0.2)",
-    duration: 3000,
-    closeOnClickOverlay: true
-});
-
-// 重置 text Toast 的默认配置
-Toast.resetDefaultOptions("text");
-```
