参考示例：

import { ComponentContent } from '@kit.ArkUI';
import { BusinessError } from '@kit.BasicServicesKit';
import web_webview from '@ohos.web.webview';
let uiContext: UIContext | undefined = undefined;
@Entry
@Component
struct Page1 {
  aboutToAppear(): void {
    uiContext = this.getUIContext()
  }
  private webviewController: web_webview.WebviewController = new web_webview.WebviewController();
  private customDialog = new CustomDialog()

  build() {
    Column() {
      Web({src:$rawfile('demo.html'),controller:this.webviewController})
        .javaScriptProxy({
          object: this.customDialog,
          name: "customDialog",
          methodList: ["openDialog"],
          controller: this.webviewController,
        })
    }
  }
}

class CustomDialog{
  openDialog(){
    let promptAction = (uiContext as UIContext).getPromptAction();
    let contentNode = new ComponentContent((uiContext as UIContext), wrapBuilder(buildText));
    try {
      promptAction.openCustomDialog(contentNode);
    } catch (error) {
      let message = (error as BusinessError).message;
      let code = (error as BusinessError).code;
      console.error(`OpenCustomDialog args error code is ${code}, message is ${message}`);
    };
  }
}

@Builder
function buildText() {
  Column() {
    Text('this is dialog')
      .fontSize(50)
      .fontWeight(FontWeight.Bold)
      .margin({bottom: 36})
  }.backgroundColor('#FFF0F0F0')
}

  then((param) => {

    testObjName.toString(param)
  })
    .catch((param) => {
      document.getElementById("demo").innerHTML = param;
      testObjName.toString(param)
    })
}
</script>

以上是beta1能力,如果不升级看下以下的demo：

import promptAction from '@ohos.promptAction'
import {GlobalContext} from '../utils/GlobalContext'
import web_webview from '@ohos.web.webview';

@Builder
export function customDialogBuilder() {
  Column() {
    Text('title ').fontSize(10).fontColor(Color.Red)
    Text('message ').fontSize(10).fontColor(Color.Blue)
    Row() {
      Button("确认").onClick(() => {
        promptAction.closeCustomDialog(AppStorage.get<number>("customDialogId") as number)
      })
      Blank().width(50)
      Button("取消").onClick(() => {
        promptAction.closeCustomDialog(AppStorage.get<number>("customDialogId") as number)
      })
    }
  }.height(100)
}

class CustomDialog{
  openDialog(){
    let that = GlobalContext.getContext().getObject("UIContext")
    if (that){
      promptAction.openCustomDialog({
        builder: customDialogBuilder.bind(that)
      }).then((dialogId: number) => {
        /*let number = AppStorage.get<number>("customDialogId") as number
        console.log('number::::'+number)*/
        AppStorage.setOrCreate("customDialogId",dialogId)
      })
    }
  }
}

@Entry
@Component
struct Page17 {
  aboutToAppear(): void {
    GlobalContext.getContext().setObject("UIContext",this)
  }
  @State message: string = 'Hello World'
  private customDialog = new CustomDialog()
  private webviewController: web_webview.WebviewController = new web_webview.WebviewController();

  build() {
    Row() {
      Column() {
        Web({src:$rawfile('demo.html'),controller:this.webviewController})
          .javaScriptProxy({
            object: this.customDialog,
            name: "customDialog",
            methodList: ["openDialog"],
            controller: this.webviewController,
          })

        Text('dialog').onClick(()=>{
          this.customDialog.openDialog()
        })
        Text(this.message)
          .fontSize(50)
          .fontWeight(FontWeight.Bold)
          .onClick(() => {
            promptAction.openCustomDialog({
              builder: customDialogBuilder.bind(this)
            }).then((dialogId: number) => {
              /*let number = AppStorage.get<number>("customDialogId") as number
              console.log('number::::'+number)*/
              AppStorage.setOrCreate("customDialogId",dialogId)
            })
          })
      }
      .width('100%')
    }
    .height('100%')
  }
}
export class GlobalContext {
  private constructor() { }
  private static instance: GlobalContext;
  private _objects = new Map<string, Object>();

  public static getContext(): GlobalContext {
    if (!GlobalContext.instance) {
      GlobalContext.instance = new GlobalContext();
    }
    return GlobalContext.instance;
  }

  getObject(value: string): Object | undefined {
    console.log(typeof (this._objects.get(value)))
    return this._objects.get(value);
  }

  setObject(key: string, objectClass: Object): void {
    this._objects.set(key, objectClass);
  }
}
