How to Access JSON attribute in typeScript

Question

How to access the JSON attributes in typescript ?

As I am making Angular Project.
`

    test:string;
    response:any;

    web_assign() {
    this.http.get(this.url1).subscribe( e => this.response = e);
    this.test = "OK";
    this.t=this.response.name2;
    return false;}

it is giving error on this line. this.t=this.response.name2; It says that it cannot read property of 'name2'

You need to do the assignment inside the subscribe callback:

this.http.get(this.url1)
    .subscribe( e => {
        this.response = e;
        this.test = "OK";
        this.t=this.response.name2;
    });

http.get is async and this.response will still not be defined on the next line, but it will be defined in subscribe callback.
