What I believe is, through ngmodel on those text boxes, you can achieve it.
Let’s try with these steps:
- text-box 1: get the length of the value entered with ngmodel(t1)
- text-box 2: get 2nd field values with ngmodel(t2)(let’s say t1 value is 50 and t2 value is 60 so the length will be failed in the condition check and you can through the error)
- If you compare both (t1.length+t2.length>100) don’t allow to enter more values(maybe disable the input field to enter values.).
Even though it may not be the complete soultion, might be helpful

ngOnInit / ionViewDidEnter for child components
Due to the way Ionic cache pages a component within a page might be shown/hidden without firing the Angular lifecycle hooks (ngOnInit etc.).
Ionic solves this for pages by using its own set of lifecycle hooks like ionViewDidEnter, but they are only available for the pages themselves.
There are however plenty of cases where a component needs to know if it’s being loaded again - for example, a map component would usually turn the GPS on/off when it’s loaded/destroyed.
Or a form might need to focus on a specific input when it’s loaded.
At the moment the only solution I’ve seen is based on @ViewChild but that requires you tightly couple the parent/child components (page/child component) which goes against a lot of best practices (and means that a new developer implementing the component will run into bugs as he wouldn’t know that they need to do some extra steps).
Are there any other options I’m missing? this is leading to a lot of weird behavior/solutions in our apps
Thanks

Return all fields from a document as an array from Firebase cloud Firestore - ionic 4
I am trying to return all fields from a document from Firebase cloud Firestore. The problem arises when I wish to store this document as an array on my page for use. In whatever instance I try I cannot seem to be able to take the array outside of the .subscribe() method. outside of the subscribe the array is undefined. I assume I am not understanding a process in typescript.
quiz.service.ts
export interface Quiz{
q1: string;
q2: string;
q3: string;
q4: string;
}
@Injectable({
providedIn: 'root'
})
export class QuizService {
quizss: Quiz[];
quiz: Quiz;
private quizCollection: AngularFirestoreCollection<Quiz>;
private quizs: Observable<Quiz[]>;
constructor(db: AngularFirestore) {
this.quizCollection = db.collection<Quiz>('quiz');
this.quizs = this.quizCollection.snapshotChanges().pipe(
map(actions =>{
return actions.map(a => {
const data = a.payload.doc.data();
const id = a.payload.doc.id;
return{ id, ...data};
});
})
);
}
getQuiz(id){
return this.quizCollection.doc<Quiz>(id).valueChanges().pipe(
map(response => response)
);
}
}
I get undefined with the following at the console.log in ngOnInit:
ngOnInit() {
this.route.queryParams.subscribe((res) => {
id = res.name;
});
answerNumber= 0;
this.question2 = this.quizService.getQuiz(id);
console.log("question pull "+ this.question2[0]);
}
returnQuiz( answerNumber) {
this.quizService.getQuiz(id)
.subscribe(res =>{
this.quiz = res;
let newPoint = {
q1: this.quiz.q1,
q2: this.quiz.q2,
q3: this.quiz.q3,
q4: this.quiz.q4,
}
this.question1[0] = newPoint.q1;
this.question1[1] = newPoint.q2;
this.question1[2] = newPoint.q3;
this.question1[3] = newPoint.q4;
return this.question1;
});
}
I have also tried this with the same error on the console log returning undefined:
ngOnInit() {
this.route.queryParams.subscribe((res) => {
id = res.name;
});
answerNumber= 0;
this.quizService.getQuiz(id)
.subscribe(res =>{
this.quiz = res;
let newPoint = {
q1: this.quiz.q1,
q2: this.quiz.q2,
q3: this.quiz.q3,
q4: this.quiz.q4,
}
this.question1[0] = newPoint.q1;
this.question1[1] = newPoint.q2;
this.question1[2] = newPoint.q3;
this.question1[3] = newPoint.q4;
});
console.log("question pull "+ this.question1[0]);
