Steps to retrieve the value stored in a variable within an Angular service from a separate component

How can I effectively share question details and an array of options from one component to another using services? What is the recommended method for storing and retrieving these values from the service?

In my question-service class:

private static  ques_optn : Array<QnA>;
constructor() { }

public setQuestion(qna :Array<QnA>) : void
{
 qna.forEach(element => { QuestionService.ques_optn.push(element)});

}

public getQuestion() : Array<QnA>
{
return QuestionService.ques_optn;

}

In my login.ts class, I am setting the value to a variable:

 {
      ques_ans: Array<QnA> = [];
      this.ques_ans;      (contains the value)
      this.questservice.setQuestion(this.ques_ans);
    }
    In my question.ts class, I am retrieving the value:</p>

    this.ques = <QnA[]>this.questservice.getQuestion();

I aim to access the values stored in the "this.ques" variable in the question.ts class

Answer №1

Based on the inquiry, it appears you plan to utilize the service as a data storage unit... However, services are not designed to hold value;

When a component incorporates a service, it is essentially injected (and created) within the component, rendering it devoid of any intrinsic data. This means it will not retain the data you wish to globally access across various components.
