#鸿蒙通关秘籍#大家好，ArkUI中共享LocalStorage怎么获取，有大佬分享下吗？

哈哈，ArkUI中共享LocalStorage，你可以使用getSharedLocalStorage函数来获取，它会提供跨组件共享存储的功能。

// index.ets
import { router } from '@kit.ArkUI';

@Entry
@Component
struct SharedLocalStorage {
  localStorage = this.getUIContext().getSharedLocalStorage()

  build() {
    Row() {
      Column() {
        Button("Change Local Storage to 47")
          .onClick(() => {
            this.localStorage?.setOrCreate("propA", 47)
          })
        Button("Get Local Storage")
          .onClick(() => {
            console.info(`localStorage: ${this.localStorage?.get("propA")}`)
          })
        Button("To Page")
          .onClick(() => {
            router.pushUrl({
              url: 'pages/GetSharedLocalStorage'
            })
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}

// GetSharedLocalStorage.ets
import { router } from '@kit.ArkUI';

@Entry
@Component
struct GetSharedLocalStorage {
  localStorage = this.getUIContext().getSharedLocalStorage()

  build() {
    Row() {
      Column() {
        Button("Change Local Storage to 100")
          .onClick(() => {
            this.localStorage?.setOrCreate("propA", 100)
          })
        Button("Get Local Storage")
          .onClick(() => {
            console.info(`localStorage: ${this.localStorage?.get("propA")}`)
          })
        Button("Back Index")
          .onClick(() => {
            router.back()
          })
      }
      .width('100%')
    }
  }
}
