I am learning ionic 2 and currently facing some ionic lifecycle issue. I want to show data after api gets success data.
import {Component} from '@angular/core';
import {NavController} from 'ionic-angular';
import {LoadingController} from 'ionic-angular';
import WooCommerceAPI from 'woocommerce-api';
@Component({
selector: 'page-category',
templateUrl: 'category.html',
})
export class CategoryPage {
information: any[] = [];
infoChild: any[] = [];
wooApi: any;
wooCat: any;
categories: any = [];
constructor(public navCtrl: NavController, public loadingCtrl: LoadingController) {
this.wooApi = WooCommerceAPI(
{
url: 'abc.com/api/v1/cat',
}
);
//here also tried to call api
}
ngOnInit() {
//here also tried to call api
}
ionViewDidLoad() {
console.log("calling api");
/*from with nginit*/
this.wooApi.getAsync('products/categories?parent=0').then((data) => {
console.log("success");
this.wooCat = JSON.parse(data.body);
//this.information = this.wooCat;
for (let i = 0; i < this.wooCat.length; i++) {
console.log("in for loop");
this.wooApi.getAsync('products/categories?parent=' + this.wooCat[i].id).then((data) => {
console.log("get success", i);
let wooChild = JSON.parse(data.body);
for (let x = 0; x < wooChild.length; x++) {
this.infoChild.push(wooChild[x]['name']);
}
//console.log(this.infoChild)
this.information.push({
'items': {
'name': this.wooCat[i]['name'],
'children': [{
'name': this.infoChild
}]
}
});
this.infoChild = [];
});
}
console.log("current data", this.information);
});
}
}
I have tried to call api with constructor() also with **ngOnInit() & ionViewDidLoad() ** data is getting properly but not reflecting on my view/html page.
My Html code is as follows:
<accordion *ngFor="let catParent of information" [title]="catParent.items.name">
<!-- (click)="itemSelected(item)" -->
<ion-list *ngFor="let catChild of catParent.items.children">
<button ion-item *ngFor="let catChildName of catChild.name">
{{ catChildName }}
</button>
</ion-list>
</accordion>
so when I click on category tab api is calling and getting response but not able to see this result on my view page, now if I click on any other tab and again click on category tab then I am able to see this data.
As I am new to ionic 2 I am not able to fix this issue. Can any one please help me to sort out this issue.
Thanks in advance :)
