【代码案例】HarmonyOS NEXT H5页面调用自定义输入法案例

// 自定义浏览器对象
export class Browser {
  inputValue: string = "";
  progress: number = 0;
  isRegistered: boolean = false;
  hideProgress: boolean = true;
  tabsController: TabsController = new TabsController();
  webController: WebviewController = new web_webview.WebviewController();
  // 跳转页面
  loadUrl(addr: string | Resource) {
    this.webController.loadUrl(addr);
  }
  // 返回页面
  back(): boolean {
    if (this.webController.accessBackward()) {
      this.webController.backward();
      return true;
    }
    return false;
  }
  // 前进页面
  forward() {
    if (this.webController.accessForward()) {
      this.webController.forward();
    }
  }
  // 刷新页面
  refresh() {
    this.webController.refresh();
  }
}

dialogController: CustomDialogController | null = new CustomDialogController({
  builder: CustomKeyboard({
    dialogClose: this.dialogClose,

  customStyle: true
});
// ...
webKeyboardObj: WebKeyboardObj = {
  // 点击登录按钮事件
  login: () => {
    promptAction.showToast({
      message: $r('app.string.custom_keyboard_to_h5_login_button'),
      duration: 2000
    });

// 注册方法到h5的js中
