我有这个:
this.activatedRoute.queryParams.subscribe((params: Params) => {
if (localStorage.getItem('queryParams')) {
this.queryParams = JSON.parse(localStorage.getItem('queryParams'));
if (this.queryParams[Object.keys(this.queryParams)[0]]) {
this.procesId = this.queryParams[Object.keys(this.queryParams)[0]];
}
}
})
当我点击相同的路线时,我想要查询queryParams。任何建议我怎么能这样做?我有菜单,所以当我点击相同的链接,我想重新加载其他组件,我在queryParams中做一些事情。但是现在只有当路线改变时它才会触发。

如果要在导航到另一个组件时重新加载组件,可以这样做:
第一个组件:
import {Component, OnInit} from '@angular/core';
export class ComponentOne implements OnInit {
constructor() {//some stuff here}
ngOnInit() {
//here the code you want to trigger by nagivating to the second component
}
}
第二部分:
import {Component, OnInit} from '@angular/core';
import {ComponentOne} from 'path_to_first_component';
export class ComponentTwo implements OnInit {
constructor(private firstComponent: ComponentOne) {} //dependency injection
ngOnInit() {
this.firstComponent.ngOnInit(); //this will call the ngOnInit from the first component
}
}
