请教下HarmonyOS Next中全局自定义弹窗怎么写？

Question

如何使用接口返回的code，给出不同的提示弹窗，比如：code===1 返回 当前 账号被其他设备登录，请重新登录 其他 显示 登录成功

Answer 1

可以使用PromptAction，参考链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-refere...

import { promptAction } from '@kit.ArkUI'
import { BusinessError } from '@kit.BasicServicesKit';

@Entry
@Component
struct LoginPage {
  @State message: string = 'Hello World';
  @State num: number = 0

  build() {
    Column() {
      Column() {
        Button('showToast').onClick(() => {
          if (this.num === 0) {
            try {
              promptAction.showToast({
                message: '当前账号被其他设备登录，请重新登录',
                duration: 2000,
                showMode: promptAction.ToastShowMode.TOP_MOST
              });
            } catch (error) {
              let message = (error as BusinessError).message
              let code = (error as BusinessError).code
              console.error(`showToast args error code is== ${code}, message is ${message}`);
            }
            ;
          } else {
            try {
              promptAction.showToast({
                message: '登录成功',
                duration: 2000,
                showMode: promptAction.ToastShowMode.TOP_MOST
              });
            } catch (error) {
              let message = (error as BusinessError).message
              let code = (error as BusinessError).code
              console.error(`showToast args error code is== ${code}, message is ${message}`);
            }
            ;
          }

        })
      }
    }
    .backgroundColor("#F1F3F5")
    .justifyContent(FlexAlign.Center)
    .width('100%')
    .height('100%')
  }
}
