Json.Parse escape newline characters

You should just escape the \
as in \\n
, your JSON becoming :
'[{"Name":"Eggs","Complete":false,"Notes":"Notes here\\n"},{"Name":"Sugar","Complete":false,"Notes":null}]';
If you cannot have access to the JSON, then your function should be :
function escapeSpecialChars(jsonString) {
return jsonString.replace(/\n/g, "\\n")
.replace(/\r/g, "\\r")
.replace(/\t/g, "\\t")
.replace(/\f/g, "\\f");
}
var groceriesJson = JSON.parse(escapeSpecialChars(jsonString));

I have a page where I am trying to parse following json string using JSON.parse
'[{"Name":"Eggs","Complete":false,"Notes":"Notes here\n"},{"Name":"Sugar","Complete":false,"Notes":null}]'
But following code gives error
"Uncaught SyntaxError: Unexpected token"
var groceriesJson = JSON.parse(jsonString);
Then I came to know that its because of
\n
in json string. So I did try this solution. But no luck. Still same error"Uncaught SyntaxError: Unexpected token"
function escapeSpecialChars(jsonString) { return jsonString.replace(/\\n/g, "\\n") .replace(/\\'/g, "\\'") .replace(/\\"/g, '\\"') .replace(/\\&/g, "\\&") .replace(/\\r/g, "\\r") .replace(/\\t/g, "\\t") .replace(/\\b/g, "\\b") .replace(/\\f/g, "\\f"); } var groceriesJson = JSON.parse(escapeSpecialChars(jsonString));
Any ideas? Thanks
---UPDATE----
I am not creating this string manually, I have c# codes that creates json string from c# objects
var jss = new System.Web.Script.Serialization.JavaScriptSerializer(); var groceries = jss.Serialize(Model);
then in javascript codes I have
var jsonString = '@Html.Raw(groceries)' var groceriesJson = JSON.parse(escapeSpecialChars(jsonString));
