How to split Json file

Ionic Framework ionic-v3
1

I need to separate the json file data
test.ts

   getDataEtalon() {
    return  this.data.getEtalon()
            .subscribe(
                  data=> {
                      this.etalon = data.split('##');
                      console.log(this.etalon);         
                  },
                  err=> console.log(err)
                  
            );
      }

{
0: "AKERMI##1988",
5: "AKIM DE DUCOR##2005",
6: "AL FATIH##2003",
9: "AMER##1984",
13: "BELAMER##2004",
15: "CHAHATA##1990",
20: "CHARH##1999",
23: "CHEIKH EL ARAB##1990",
24: "DAHESS##1999",
35: "DARIKE##1991",
44: "DARMAN##1998",
50: "DAYJUR##1991",
51: "DJARNI DES FORGES##1995",
55: "DJELMANE##1999",
77: "DJOURDAN##1999",
83: "DORMANE##1984",
}

EXCEPTION: data.split is not a function

data is this JSON object? You can’t use split() on an object, only on strings. You have to iterate over your object and apply the function to your values.

I try but it does not work

 getDataEtalon() {

    return  this.data.getEtalon()
            .subscribe(
                  data=> {
                    for ( var i = 0 ;  i <= data.length ; i++)
                          {
                         this.etalon = data[i].split('##');
                         }
                          console.log(data);
                         
                    }  );
      }

Because it’s an object and not an array, keys are different.

for(let key in data) {
    ... data[key].split("##") ...
}

But FYI now you’re replacing this.etalon every time you loop through…

works , but it only displays the last name

   getDataEtalon() {
   
    return  this.data.getEtalon()
            .subscribe(
                  data=> {
                    for (let key in data)
                          {
                         this.etalon = data[key].split('##');
                         }
                          console.log(this.etalon);
                         
                    }  );
      }

You need to provide some more information for us to be able to help you further - we have no idea what you’re trying to achieve exactly. What does your HTML look like?

Also, if this is how you indent your code in your project, I would really recommend doing it like this:

getDataEtalon() {
	return this.data.getEtalon().subscribe(
		data => {
			for (let key in data) {
				this.etalon = data[key].split('##');
			}
			console.log(this.etalon);
		}
	);
}

It really improves readability. Also, if this is an HTTP call you probably want to handle potential errors

getDataEtalon() {
	return this.data.getEtalon().subscribe(
		data => {
			for (let key in data) {
				this.etalon = data[key].split('##');
			}
			console.log(this.etalon);
		},
		err => {
			console.log(err);
		}
	);
}
