鸿蒙HarmonyOS之跳转页面并传递参数的方法

一、使用router路由跳转页面并携带参数

1、导入库

import router from '@kit.ArkUI';

2、跳转页面并携带参数

export class ActivityResponse {
......
}

（1）携带多个参数

router.pushUrl({
      url: 'pages/NextPage',
      params: {
            name: '名字', //string类型
            avator: '头像', //string类型
            size: 大小, //number类型
            responsedata: '某个对象数据' //ActivityResponse类型
      }
})

NextPage页解析：

private responseData: ActivityResponse = new ActivityResponse();
private name: string = ''
private avator: string = ''
private size: number = 0
  
......
  
let params = router.getParams() as Record<string, number | string | ActivityResponse>;
this.responseData= params.result as ActivityResponse;
this.name= params.uri as string;
this.avator= params.infoW as string;
this.size= params.infoH as number;

（2）携带一个参数，参数是类对象

在参数过多的情况下，可以将传递的参数封装为类，以对象方式传递更方便接收解析

private curr_data: ActivityResponse = new ActivityResponse();
......
router.pushUrl({
	url: 'pages/NextPage',
    params: this.curr_data
},router.RouterMode.Standard,(err)=>{
    if (err) {
      console.error(`跳转页面失败, code is ${err.code}, message is ${err.message}`);
      return;
    }
  })

NextPage页解析：

this.params = router.getParams() as ActivityResponse;

二、使用navigation
