ionic4 页面跳转传值和新页面取值

页面跳转 ：

        

<ion-row *ngfor="let item of aboutdata.stockdata"

[routerlink]="[ '/stock-details']"     /*  跳转页面*/

[queryparams]="item"                   /*  传的参数*/>

 

 

新页面取值：

  

       

import { component, oninit } from '@angular/core';

import {activatedroute} from "@angular/router";  /* 引入控件*/

@component({

selector: 'app-stock-details',

templateurl: './stock-details.page.html',

styleurls: ['./stock-details.page.scss'],

})

export class stockdetailspage implements oninit {

sparams:any={};

constructor(public _activerouter: activatedroute) {

this._activerouter.queryparams.subscribe(params=> {

console.log(params);

this.sparams=params;

console.log(this.sparams.symbol);

})

}

ngoninit() {

 

 

 

}

}
