#鸿蒙通关秘籍#如何在页面跳转时传递参数

在调用Router模块的方法时，可以添加一个params属性，用于传递需要的参数。以下是从主页到详情页传递参数的示例：

import { router } from '@kit.ArkUI';
class DataModelInfo {
  age: number = 0;
}

class DataModel {
  id: number = 0;
  info: DataModelInfo|null = null;
}

function onJumpClick(): void {
  let paramsInfo: DataModel = {
    id: 123,
    info: {
      age: 20
    }
  };

  router.pushUrl({
    url: 'pages/Detail', 
    params: paramsInfo 
  }, (err) => {
    if (err) {
      console.error(`Invoke pushUrl failed, code is ${err.code}, message is ${err.message}`);
      return;
    }
    console.info('Invoke pushUrl succeeded.');
  })
}

在目标页面的onPageShow()生命周期回调中，可以通过router.getParams()方法获取传递的参数：

import { router } from '@kit.ArkUI';

class InfoTmp {
  age: number = 0;
}

class RouTmp {
  id: object = () => {};
  info: InfoTmp = new InfoTmp();
}

const params: RouTmp = router.getParams() as RouTmp; 
const id: object = params.id;
const age: number = params.info.age;
