Angular2 call function in another function with same class and use first functions property in second

I have 2 functions in a class, both class getting data from API calls.

Here is the First function

getQuotes(){
    this.quoteService.getQuotes()
    .subscribe(
      quotes => {
        this.quotCode = this.quotes.BasicDetails[0].QuotCode;
        }
      });
}

Second Function

getOption(){
    this.quoteService.getOptions()
    .subscribe(
            options => {
     })
}

I want to get data from this line from first function

this.quotCode = this.quotes.BasicDetails[0].QuotCode;

and based on this.quotCode getOption() will have different params to pass and will get diff. response also. so it is necessary to use this.quotCode in second function

I'm calling getQuotes() in constuctor()

Can anyone please help me out? Thanks

RXJS mergeMap is the operator you need : this way, you will execute the second request once the first one succeeds.

this.quoteService.getQuotes().mergeMap( quotes => {
    // Do whatever you need to do with quotes
    return this.quoteService.getOptions()
}).subscribe( options => {
    // Do whatever you need with options
});
