I'm sending the below string.
"{"English":{"name":"test & test","descpt":"test"},"Telugu":{"name":"test","descpt":"test"}}"
request payloads are only taking the part before the "&"
Does this have any solution?
You can use encodeURIComponent().
It will escape all the characters that cannot occur verbatim in URLs:
var wysiwyg_clean = encodeURIComponent(stringValue);
In this example, the ampersand character & will be replaced by the escape sequence %26, which is valid in URLs.
Hi you can usin encodeURI() Method in Javascript.
It will solve the issue while sending.
var t= encodeURI("{"English":{"name":"test & test","descpt":"test"},"Telugu":{"name":"test","descpt":"test"}}");
And Decode at the server side. depending on what technology you used.
I am guessing that's probably because of double quotes,If you are sending objects with in objects make sure double check with quotes. Please enclode your whole string with single quotes. you can use:
'{"English":{"name":"test & test","descpt":"test"},"Telugu":{"name":"test","descpt":"test"}}'
If you want to send this to the request payload, then
encodeURIComponent('{"English":{"name":"test & test","descpt":"test"},"Telugu":{"name":"test","descpt":"test"}}')

Can somebody tell me the difference between two in html. i was found this ： in url but when i'm connecting with request in node js, the respond is ERR_UNESCAPED_CHARACTERS.
Which is confusing because symbols are like : (colon).
Is there a way to solve this?
You can use encodeURI to encode the special character. It assumes that the input is a complete URI that might have some characters which need encoding in it.
encodeURI(url)
This function encodes special characters, except: , / ? : # & = + $ #
(Use encodeURIComponent() to encode these characters).
Tip: Use the decodeURI() function to decode an encoded URI.
When searching my db all special characters work aside from the "+" - it thinks its a space. Looking on the backend which is python, there is no issues with it receiving special chars which I believe it is the frontend which is Javascript
what i need to do is replace "+" == "%2b". Is there a way for me to use create this so it has this value going forth?
You can use decodeURIComponent('%2b'), or encodeUriComponent('+');
if you decode the response from the server, you get the + sign-
if you want to replace all ocurrence just place the whole string insde the method and it decodes/encodes the whole string.
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。"}')
I'm using Ajax calls to get some variables data from the DB.
some of my data stored on the database contains double quotes (").
when I'm trying to display the variable :
value="'+ucontent+'"
the string gets cut in the middle (of course)
I have tried using escape() but im getting a non readable result - something with %4%2 etc...
how can i escape the double quotes in the variable and still keep a readable string...
BTW - I'm using UTF8 characters.
decodeURIComponent()
might be helpful
what escape actually does is replace some characters with a hexadecimal escape sequence.
That is the reason why you are getting unreadable string like %4%2.
Depends on what language in server side you are using.
If it is php, then use json_encode to encode the response string.
If it is ruby(rails), then use escape_javascript to escape the response string.
You can just use \" if you don't use an encoder. See this.
I have an issue with submitting post data. I have a form which have a couple of text fields in, and when a button is pressed to submit the data, it is run through a custom from validation (JS), then I construct a query string like
title=test&content=some content
which is then submitted to the server. The problem I had is when I have '&' (eg  ) entered into one of the inputs which then breaks up the query string. Eg:
title=test&content=some content  
How do I get around this?
Thanks in advance,
Harry.
Run encodeURIComponent over each key and value.
var title = "test";
var content = "some content   ";
var data = encodeURIComponent('title') + /* You don't actually need to encode this as it is a string that only contains safe characters, but you would if you weren't sure about the data */
'=' + encodeURIComponent(title) +
'&' + encodeURIComponent('content') +
'=' + encodeURIComponent(content);
Encode the string..when you want to encode a query string with special characters you need to use encoding. ampersand is encoded like this
title=test&content=some content %26
basically any character in a query string can be replaced by its ASCII Hex equivalent with a % as the prefix
Space = %20
A = %41
B = %42
C = %43
...
You need to encode your query to make it URL-safe. You can refer to the following links on how to do that in JS:
http://xkr.us/articles/javascript/encode-compare/
http://www.webtoolkit.info/javascript-url-decode-encode.html
You said:
...and when a button is pressed to submit the data, it is run through a custom from validation (JS), then I construct a query string...
In the section where you are building the query string you should also run the value of each input through encodeURIComponent() as David Dorward suggested.
As you do - be careful that you only assign the new value to your processed query string and NOT the form element value, otherwise your users will think their input was somehow corrupted and potentially freak out.
[EDIT]
I just re-read your question and realized something important: you're encoding an   ;character. This is probably a more complicated issue than other posters here have read into. If you want that character, and other &code; type characters to transfer over you'll need to realize that they are codes. Those characters &, n, b, s, p and ; are not themselves the same as " " which is a space character that does not break.
You'll have to add another step of encoding/decoding. You can place this step either before of after the data is sent (or "POSTed").
Before:
(Using this question's answers)
var data = formElement.value;
data = rhtmlspecialchars(data, 0);
Which is intended to replace your "special" characters like with " " so that they are then properly encoded by encodeURIComponent(data)
Or after:
(using standard PHP functions)
<?PHP
$your_field_name = htmlspecialchars_decode(urldecode($_POST['your_field_name']));
?>
This assumes that you escaped the & in your POST with %26
If you replaced it with some function other than encodeURIComponent() you'll have to find a different way to decode it in PHP.
This should solve your problem:
encodeURIComponent(name)+'='+encodeURIComponent(value)+'&'+encodeURIComponent(name2)+'='+encodeURIComponent(value2)
You need to escape each value (and name if you want to be on the safe side) before concatenating them when you're building your query.
The JavaScript global function encodeURIComponent() does the escaping.
The global function escape() (DOM) does this for you in a browser. Although people are saying it is not doing the escaping well for unicode chars. Anyway if you're only concerned about '&' then this would solve your problem.
