I have been trying to parse a JSON string, but I keep getting an error message that says “JSON.parse: bad control character in string literal”. I have tried different approaches, but none of them seem to work. The code that I’m using is below:
const json = '{"result":true, "count":42}';
const obj = JSON.parse(json);
console.log(obj.count);
I am not sure what I am doing wrong or what the error message means. I have looked online for help, but I haven’t found a solution that works for me. Can someone please help me understand what is causing the error and how to fix it?
I have also tried using the escape character “” before the special characters in the JSON string
One possible solution for this issue would be to use the `JSON.parse()` method. This method allows you to convert a JSON string to a JavaScript object. You can then access the object's properties using dot notation. In your specific case, you could try the following code: ``` var obj = JSON.parse(daRead more
One possible solution for this issue would be to use the `JSON.parse()` method. This method allows you to convert a JSON string to a JavaScript object. You can then access the object’s properties using dot notation. In your specific case, you could try the following code:
“`
var obj = JSON.parse(data.replace(/[u0000-u0019]+/g,””));
“`
Here, `data` is the JSON string you want to parse, and the `replace()` method is used to remove any control characters from the string. After that, the `JSON.parse()` method is called on the modified string.
It’s important to note that using `JSON.parse()` on untrusted JSON data can be a security risk, as it may allow an attacker to execute arbitrary code on your page. To mitigate this risk, you can use a library like `DOMPurify` to sanitize the JSON data before parsing it.
I hope this helps! Let me know if you have any questions or concerns.
