I have a jsonData like below, I am not able to parse it withjQuery.parseJSON() functon due to the presence of escape characters inside the value of the String and it gives me this error:
Error:
SyntaxError: "JSON.parse: bad escaped character at line X column Y of the JSON data"
jsonData which I am trying to parse using above function:
"reference_data": "{FastDelivery:'[\'facet.delivery.regions.1\'::[{ShippingCountry:\"US\"}]]'}"
One of way to enable parsing of this jsonData is by removing that escape character but I couldn't find any options/right way in Internet/StackOverflow to do it. Can somebody help me here with this small request?
Tried putting extra \ before each \ to make it \ before parsing - but it didnt work.

I have below string
'[{\'Question\': \'a Names and Roles (if known)\'}]'
I need to convert it into JSON.
I tried JSON.parse(s)
I got error SyntaxError: Unexpected token ' in JSON at position 2
and also
> eval(s)
SyntaxError: Unexpected string
Any help would be really appreciable
Problem is that you need to pass string inside JSON.parse(s).
Please make sure s is a string
'[{*Question\': at the point of asterisk you need a \' don't you?
So it should be
'[{\'Question\': \'a Names and Roles..
EDIT
Found this after a bit of research. Problem is with the single quote. Replace them with double quotes, you are good to go. See this fiddle, to check this out in action.
Additionally, I had to modify "[\'NA\']" in your string, to get it to working. That is also invalid JSON. If it is an array that you want it to be, you should put it like [\"NA\"].
I'm trying to parse a String to JSON in NodeJS/Javascript, this is my string (which I cannot change, coming from an external database):
'{\\"value1\\":\\"XYZ\\",\\"value2\\":\\"ZYX\\"}'
I'm calling:
JSON.parse(row.raw_data)
But are getting:
SyntaxError: Unexpected token \ in JSON at position
I actually thought double escape was the correct way of escaping in string/JSON.
Your JSON is invalid. You've said you can't change it, which is unfortunate.
It looks like it's been double-stringified but then the outermost quotes have been left off. If so, you can fix it by adding " at each end and then double-parsing it, like this:
var str = '{\\"value1\\":\\"XYZ\\",\\"value2\\":\\"ZYX\\"}';
str = '"' + str + '"';
var obj = JSON.parse(JSON.parse(str));
console.log(obj);
Ideally, though, you'll want to go through the database and correct the invalid data.
I actually thought double escape was the correct way of escaping in string/JSON.
In JSON, strings are wrapped in double quotes ("), not double escapes. You only escape double quotes within strings (with a single \).
If you've been creating JSON strings manually (in code), don't. :-) Instead, create the structure you want to save, and then stringify it. Building JSON strings manually is error-prone, but a proper JSON stringifier will be reliable.
I get the syntax error when I try to pass the following string:
JSON.parse("[{\"Date\": \"4/4/2016 4:15:19 PM\", \"Message\":\"<h3>New
Message</h3> Generated at 4/4/2016 4:15:19 PM.<br/><br/>Heavy Responsive
URL: <a href=\"https://performingarts.withgoogle.com/en_us\" ></a><br/><br/>
<img src=\"https://s-media-cache-ak0.pinimg.com/236x/06/bd/ac/06bdacc904c12abdce3381ba1404fd7e.jpg\" /> \"} ]");
I know that the error come from the link when I use double quote.
If I use single quote then no issue, but the data is getting from server side, I got no control over what going to pass in so I can only control on my side.
From what I read from the internet so far, I tried the following:
Use JSON.stringify first, then only use JSON.parse. I can parse
with no issue but problem occur when I try to loop the data. Instead
of looping it as JSON, the loop take the data as string and loop
every single text.
Escape every double quote which I'm currently doing, but it's not
working as shown above. But if I replace every double quote to
literal, I'm afraid some of the message that suppose to be double
quote will turn into literal as well, which will result in weird
looking message.
Please advice what other alternative I have to solve this.
You have JSON embedded in a JavaScript string literal.
" and \ are special characters in JSON and are also special characters in a JavaScript string literal.
href=\"https: escapes the " in the JavaScript string literal. It then becomes a " in the JSON. That causes an error.
When you want the " as data in the JSON you must:
Escape the " for JavaScript (as you are doing already)
Escape the " for JSON by adding a \.
Escape the \ for JavaScript
href=\\\"https:
I'm running a NodeJS app that gets certain posts from an API.
When trying to JSON.parse with special characters in, the JSON.parse would fail.
Special characters can be just any other language, emojis etc.
Parsing works fine when posts don't have special characters.
I need to preserve all of the text, I can't just ignore those characters since I need to handle every possible language.
I'm getting the following error:
"Unexpected token �"
Example of a text i'm supposed to be able to handle:
"summary": "★リプライは殆ど見てません★ Tokyo-based E-J translator. ここは流れてくるニュースの自分用記録でRT＆メモと他人の言葉の引用、ブログのフィード。ここで意見を述べることはしません。「交流」もしません。関心領域は匦"�アイルランドと英国（他は専門外）※Togetterコメ欄と陰謀論が嫌いです。"
How can I properly parse such a text?
Thanks
You have misdiagnosed your problem, it has nothing to do with that character.
Your code contains an unescaped " immediately before the special character you think is causing the problem. The early " is prematurely terminating the string.
If you insert a backslash to escape the ", your string can be parsed as JSON just fine:
x = '{"summary": "★リプライは殆ど見てません★ Tokyo-based E-J translator. ここは流れてくるニュースの自分用記録でRT＆メモと他人の言葉の引用、ブログのフィード。ここで意見を述べることはしません。「交流」もしません。関心領域は匦\\"�アイルランドと英国（他は専門外）※Togetterコメ欄と陰謀論が嫌いです。"}';
console.log(JSON.parse(x));
You need to pass a string not as an object.
Example
JSON.parse('{"summary" : "a"}');
In your case it should be like this
JSON.parse(
'{"summary" : "★リプライは殆ど見てません★ Tokyo-based E-J translator. ここは流れてくるニュースの自分用記録でRT＆メモと他人の言葉の引用、ブログのフィード。ここで意見を述べることはしません。「交流」もしません。関心領域は匦�アイルランドと英国（他は専門外）※Togetterコメ欄と陰謀論が嫌いです。"}')
So I am trying to export a three.js scene using the SceneExporter, I am just doing this
var output = new THREE.SceneExporter().parse(scope.renderingEngine.scene);
When doing this, I get an error
Uncaught SyntaxError: Unexpected token u
Which occurs at line 750 of SceneExporter.js (which is the line where the JSON gets parsed; new THREE.SceneExporter().parse(scope.renderingEngine.scene);)
I don't have anything fancy going on in the scene, just a bunch of geometries. I even tried a scene with no textures in it and still got this error.
Now, if I change that line to simply return the output then JSON.stringify(output) and save this file, the file's JSON does not validate. I get the following error
Parse error on line 1:
"{ \n\t\"metadat
^
Expecting '{', '['
And here is line 1-10 of the JSON file
"{
\n\t\"metadata\": {
\n\t\t\"formatVersion\": 3.2,
\n\t\t\"type\"\t\t: \"scene\",
\n\t\t\"generatedBy\"\t: \"SceneExporter\",
\n\t\t\"objects\": 153,
\n\t\t\"geometries\": 144,
\n\t\t\"materials\": 5,
\n\t\t\"textures\": 1\n\t
},
\n\n\t\"urlBaseType\": \"relativeToScene\",
Anyone else having this issue?
The syntax error is a "Unexpected token: ILLEGAL" character, probably thrown by your use of "\n\t\t" and others (escape sequences) outside strings. I don't know what you are trying to achieve with escape sequences outside strings, and I don't even know if special characters should be used in JSON.
Also, I see "\" at some of your strings. You can't use "\". You can, however, use "\", that is escape sequence for a "\". Using a single "\" inside a string will give you the "Unexpected token: ILLEGAL" error. "\" must always be followed by a character that makes a valid escape sequence.
