var str = "{"data":"{\n \"taskNames\" : [\n \"01 Jan\",\n \"02 Jan\",\n \"03 Jan\",\n \"04 Jan\",\n \"05 Jan\",\n \"06 Jan\",\n \"07 Jan\",\n \"08 Jan\",\n \"09 Jan\",\n \"10 Jan\",\n \"11 Jan\",\n \"12 Jan\",\n \"13 Jan\",\n \"14 Jan\",\n \"15 Jan\",\n \"16 Jan\",\n \"17 Jan\",\n \"18 Jan\",\n \"19 Jan\",\n \"20 Jan\",\n \"21 Jan\",\n \"22 Jan\",\n \"23 Jan\",\n \"24 Jan\",\n \"25 Jan\",\n \"26 Jan\",\n \"27 Jan\"]}

Method 1 : Using replace() method with a regular expression

// Input string
let origString = 'string / with some // slashes /';
 
// Display
console.log(origString);
 
// Replacement for slash
let replacementString = '*';
 
// Replaced string
let replacedString = origString.replace(/\//g, replacementString);
 
// Display output
console.log(replacedString);

Output

string / with some // slashes /
string * with some ** slashes *

Method 2: Using the JavaScript split() method

// Input String with slashes
let origString = 'string / with some // slashes /';

// Display input string
console.log(origString);

// Replacement for slash
let replacementString = '*';

// Replaced String
let replacedString = origString.split('/').join(replacementString);
            
// Display output
console.log(replacedString);

Output

string / with some // slashes /
string * with some ** slashes *

Method 3: Using JavaScript replaceAll() method

// Input string
let origString = 'string / with some // slashes /';
// Display input string
console.log(origString);

// replacement cahracter
let replacementString = '*';

// Replace all slash using replaceAll method;
let replacedString =
            origString.replaceAll('/', '*');

// Display output
console.log(replacedString);

Output

string / with some // slashes /
string * with some ** slashes *

JSON.parse(JSON.stringify(req.body.json)) did the work for me.

After stumbling for hours, this worked out. You can use this function to convert your json string with backslashes to a javascript object.

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

Try to do JSON.parse(data), it should work. In most cases when the JSON is generated from Sitecore or any backend, they will come with all the slashes.

In React Native , This worked for me

name = "hi \n\ruser"
name.replace( /[\r\n]+/gm, ""); // hi user

You need to deserialize the JSON once before returning it as response. Please refer below code. This works for me:

JavaScriptSerializer jss = new JavaScriptSerializer();
Object finalData = jss.DeserializeObject(str);

tl;dr: You don't have to remove the slashes, you have nested JSON, and hence have to decode the JSON twice: DEMO (note I used double slashes in the example, because the JSON is inside a JS string literal).

I assume that your actual JSON looks like

{"data":"{\n \"taskNames\" : [\n \"01 Jan\",\n \"02 Jan\",\n \"03 Jan\",\n \"04 Jan\",\n \"05 Jan\",\n \"06 Jan\",\n \"07 Jan\",\n \"08 Jan\",\n \"09 Jan\",\n \"10 Jan\",\n \"11 Jan\",\n \"12 Jan\",\n \"13 Jan\",\n \"14 Jan\",\n \"15 Jan\",\n \"16 Jan\",\n \"17 Jan\",\n \"18 Jan\",\n \"19 Jan\",\n \"20 Jan\",\n \"21 Jan\",\n \"22 Jan\",\n \"23 Jan\",\n \"24 Jan\",\n \"25 Jan\",\n \"26 Jan\",\n \"27 Jan\"]}"}

I.e. you have a top level object with one key, data. The value of that key is a string containing JSON itself. This is usually because the server side code didn't properly create the JSON. That's why you see the \" inside the string. This lets the parser know that " is to be treated literally and doesn't terminate the string.

So you can either fix the server side code, so that you don't double encode the data, or you have to decode the JSON twice, e.g.

var data = JSON.parse(JSON.parse(json).data));

try this

var finalData = str.replace(/\\/g, '');

Your string is invalid, but assuming it was valid, you'd have to do:

var finalData = str.replace(/\\/g, "");

When you want to replace all the occurences with .replace, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.

Cheers
