String to Object in Js

how convert string to object in javaScript

Although you haven't mentioned JSON explicitly, this data looks like JSON. You can use JSON.parse() to turn JSON strings into JavaScript variables

However, the string you've posted isn't actually valid JSON because of a couple of syntax errors. You can fix those to get (what I assume is) the intended object structure:

1) remove the extra double-quote before new jersey

2) add curly braces at either end to make it into a valid object.

3) remove extra comma after the last array entry (although a lot of parsers will tolerate this in fact)

So you end up with

{ 
  "users": [
    { "name":"John", "age":30, "city":"New York"},
    { "name":"Mike", "age":25, "city":"new jersey"}
  ]
}

And this can be parsed easily:

var obj = '{ "users": [{    "name": "John",    "age": 30,    "city": "New York"  },  {    "name": "Mike",    "age": 25,    "city": "new jersey"  }]}';
var data = JSON.parse(obj);
console.log(data);console.log("----------");
//example of gettng a specific property, now it's a JS variableconsole.log(data.users[0].name);

Converting string to object with Javascript

"JwtBody { user_id: 1, auth_id: 1}" is obviously not a standard json string,So you can try this.

function strToObj(str){
   var obj = {};
   if(str&&typeof str ==='string'){
       var objStr = str.match(/\{(.)+\}/g);
       eval("obj ="+objStr);
   }
   return obj
}

Safely turning a JSON string into an object

JSON.parse(jsonString) is a pure JavaScript approach so long as you can guarantee a reasonably modern browser.

javascript string to object

var str='{"a":"www"}';
var obj = JSON.parse(str);

convert string to object from html input element

use json5 or Relaxed JSON library.

here is example using json5 library

let string = `  {
    name: "root",
    backlog: [
      {name: "log#1"},
      ]
    }`;
    
 let object = JSON5.parse(string);
 console.log(object)

<script src="https://unpkg.com/json5@^2.0.0/dist/index.min.js"></script>

JavaScript Split String into Object with Properties

If order.customer.note is your example string, then this should work:

let data = "Child 1 First Name: Ali\nChild 1 Gender: Female\nChild 1 Hair Color: Blonde\nChild 1 Hair Style: Wavy\nChild 1 Skin Tone: Tan\nChild 2 First Name: Morgan \nChild 2 Gender: Female\nChild 2 Hair Color: Brown\nChild 2 Hair Style: Ponytail\nChild 2 Skin Tone: Light\nRelationship 1 to 2: Brother\nRelationship 2 to 1: Brother\n";//let data = JSON.stringify(rawNoteData);  <-- Don't do this. order.customer.note is not an object.
let foo = data.split("\n").reduce(function(obj, str, index) {  let strParts = str.split(":");  if (strParts[0] && strParts[1]) { //<-- Make sure the key & value are not undefined    obj[strParts[0].replace(/\s+/g, '')] = strParts[1].trim(); //<-- Get rid of extra spaces at beginning of value strings  }  return obj;}, {});
console.log(foo);

Convert String to Object gives error due to double quotes at start and end

try this

const jsonStr =
  '"{ "type": "object", "properties": {  "hostUrl": { "type": "string", "description": "hostUrl",   }, }, }"';

var json = jsonStr
  .substring(1, jsonStr.length - 1)
  .replaceAll("},", "}")
  .replaceAll(" ", "")
  .replaceAll(",}", "}");

json

{
  "type": "object",
  "properties": {
    "hostUrl": {
      "type": "string",
      "description": "hostUrl"
    }
  }
}
