      })

        setTimeout(() => {

        }, 2000)

当前不支持Refresh组件+Web组件实现webview内下拉刷新，但可通过三方开源库@ohos/pulltorefresh实现该效果，三方库地址：https://ohpm.openharmony.cn/#/cn/detail/@ohos%2Fpulltorefresh

安装：ohpm install @ohos/pulltorefresh

示例代码：

import web_webview from '@ohos.web.webview'; 
import { PullToRefresh } from '@ohos/pulltorefresh' 
 
@Entry 
@Component 
struct Index { 
  controller: web_webview.WebviewController = new web_webview.WebviewController(); 
  @State dataArray: Array<string> = [] 
  private scroller: Scroller = new Scroller(); 
 
 
  @Builder 
  getContentView() { 
    Column() { 
      Web({ src: 'http://www.huawei.com', controller: this.controller }) 
    }.width('100%').height('100%') 
  } 
 
 
  build() { 
    Scroll(this.scroller) { 
      PullToRefresh({ 
        data: $dataArray, 
        scroller: this.scroller, 
        customList: () => { 
          this.getContentView(); 
        }, 
        onRefresh: () => { 
          return new Promise<string>((resolve, reject) => { 
            setTimeout(() => { 
              resolve('') 
              this.controller.loadUrl('https://www.huawei.com') 
            }, 1000); 
          }); 
        }, 
      }).width('100%').height('100%') 
    }.width('100%').height('100%') 
  } 
}
