订阅后将值保存到数组或变量中

Question

I want to save the data after http request and subscribing like below but I cant see the data at the first index. It looks like this within the browser. With this.mySet[0] I have not access to this. What it wrong?

[]0: "test"length: 1__proto__: Array(0)

api.service.ts:409

myComponent.ts

     mySet = [];
     getLageSub()  {

       this.apiService.getLage().subscribe(data => {this.mySet.push(data)});
console.log(this.mySet)<------here is my output but I will need it elsewhere 

      }

myService.ts

getLage()  {
    let url = 'rest/getData-pool';

    try {
      return this.http.post(url, {}, this.getPutHeaders()).map((res) =>res.json())

    } catch (error) {

      console.log(error);
    }
  }

Answer 1

Try this case :

mySet : any;Constructor(){this.mySet = [];}

getLageSub() { this.apiService.getLage().subscribe(data => {this.mySet.push(data)}); console.log(this.mySet)<------here is my output but I will need it elsewhere }

Answer 2

I hope it will help:

mySet : any;Constructor(){this.mySet = [];}

getLageSub() { this.apiService.getLage().subscribe(data => {this.mySet.push(JSON.parse(JSON.stringify(data)))}); console.log(this.mySet)<------here is my output but I will need it elsewhere }
