String replacing error


When i try to replace the string showing this error

below my code:"

export class HomePage {

	  qrData = null;
	  qrData2= null;
  	createdCode = null;
  	scannedCode = null;
	  data:any = {};

  constructor(public navCtrl: NavController) { = ''; = '';


    createCode() {
    this.createdCode = JSON.stringify(;
     let jsonString = this.createCode;
     jsonString = jsonString.replace(/("{|}")/gi,'"');


Please help me anyone


typo. jsonString becomes the function createCode, where you probably want createdCode


can you give me the example of code how to remove quotation from string


They just told you what the problem is of your code. Did fixing it work?
