Escape dotnet resources in javascript

I need to read dot ner reesources string in java script as mention below.
var resources = #Html.ResourceStrings("Home_General_", Resources.ResourceManager);
The above line will render all the resources (from Dot net resource file) which start with resource key as "Home_General_"
Some of the values from the resources are like "Hi "XYZ" are you there" i.e The string contains quotes character.
If the string has quotes the above call fails.
The one way to avoid this problem is escape the special character as "Hi \"XYZ\" are you there"
Any other way where we can avoid this, As I don't want to pollute my resource string with lot of escape (\) characters.

You need to Javascript-escape any string when you render it as a Javascript string literal.
You must also remove the outer quotes from the string resource; that should be text, not a half-valid Javascript expression.

Use code like this to retrieve a single resource string:
var resourceXYZ = '#Html.Raw(HttpUtility.JavaScriptStringEncode(Resources.ResourceManager.GetString("Home_General_XYZ")))';
We do the following:
We get the resource string via Resources.ResourceManager.GetString().
We pass the result to HttpUtility.JavaScriptStringEncode to escape any special characters in JavaScript.
We pass the result to Html.Raw() to prevent Razor from applying HTML encoding on this string.
We then output the text enclosed in single quote quaracters into the page.
The function Html.ResourceStrings is not a standard function that is part of MVC. Someone at your place must have written it. If you show us this code, we could tell you how to rewrite it to return valid JavaScript literals.

You could wrap your #Html.ResourcesString(...) with HttpUtility.JavaScriptStringEncode which will handle all escape issues.
var resources = #HttpUtility.JavaScriptStringEncode(Html.ResourceStrings("Home_General_", Resources.ResourceManager));

Javascript .replace() of the character " with the characters \"

I am trying to pass a JSON string to a C# .exe as a command line argument, from Javascript as a node.js child-process. For the sake of argument my JSON looks something like this:
string jsonString = '{"name":"Tim"}'
The issue with passing this as a C# arg is that the double quotation marks must be retained if I hope to parse it in the C# code. As such, what I need to pass into the C# command line needs to look something like this, where I escape the double quotation mark:
string jsonStringEscaped = '{\"name\":\"Tim\"}'
The motivation for doing this is that it allows me to maintain a consistent object structure across the two languages, which is obviously highly desirable for me.
In order to achieve this, I am attempting to use the Javascript .replace() method prior to sending the argument to the C#, and to do this I use a simple RegEx:
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\"")
Unfortunately, this returns something of the form '{\\"name\\":\\"Tim\\"}' which is useless to me.
I have tried variations on this:
string jsonStringEscaped = jsonString.replace(/\"/g,"\\ \"")
\\ returns '{\\ "name\\ ":\\ "Tim\\ "}'
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\\")
\\ returns '{\\\\name\\\\:\\\\Tim\\\\}'
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\")
\\ is invalid
string jsonStringEscaped = jsonString.replace(/\"/g,"\\\ ")
\\ returns '{\\ name\\ :\\ Tim\\ }'
I have tried variations where the second .replace() argument is contained within single quotation marks '' rather than double quotation marks "" with no success.
Can anyone tell me what I am doing wrong? Better yet, can anyone suggest a more efficient method for doing what I am trying to achieve?

Unless I'm misreading you, I think you're just trying to escape a character that doesn't need to be escaped in your regex (").
var jsonString = '{"name":"Tim"}'
var escaped = jsonString.replace(/"/g, '\\"');
// escaped == "{\"name\":\"Tim\"}"

How to parse Json with jquery having special chars in it?

I got a json structure somehow as below and my question is how can i parse this with jQuery so that i can use it like myJson[0].name and than alert it so that "M\\xe9t\\xe9o" = Météo.
Jquery tells me this is invalid json why ?
Json uses double backslash if i use single backslash ("M\xe9t\xe9o") Jquery is OK with the syntax.
var jsonObj = '{"title":[{"id":"1","name": "M\\xe9t\\xe9o"},{"id":"2","name": "Meteo"}]}';
var myJson = jQuery.parseJSON(jsonObj);

The JSON syntax only allows \uxxxx escapes.
Change it to "M\\u00e9t\\u00e9o".
If you use a single backslash, it gets parsed by the Javascript string literal, so the actual string value contains the real Unicode character, not an escape. In other words, "M\xe9t\xe9o" === "Météo"

It is looks like the json was incorrectly (manually?) encoded. When you encode it in UTF-8, e.g. with PHP, you'll get:
{"title":[{"id":"1","name": "M\u00e9t\u00e9o"},{"id":"2","name": "Meteo"}]}
which is correctly parsed by JS. But \xe9 is unrecognized by parser.

Can you create a JavaScript string without using ' or " quotes?

I have a JS file with some XML in it, where the XML is supposed to get converted to a word by the server.
E.g.
var ip = "<lang:cond><lang:when test="$(VAR{'ip_addr'})">$(VAR{'ip_addr'})</lang:when></lang:cond>";
This gets converted to:
var ip = "192.168.0.0";
However, in case the server doesn't work as intended, I don't want there to be a syntax error, and this is VERY important. Currently there would be a syntax error because the language uses both types of quotes. I can't think of a way to get around this, but perhaps there's another way to do quotes in JavaScript? Or to create a string?
For example, in Python I'd use triple quotes:
ip = """<lang:cond><lang:when test="$(VAR{'ip_addr'})">$(VAR{'ip_addr'})</lang:when></lang:cond>"""
Anyone have a bright idea?

I have had to create strings without quotes for a project as well. We were delivering executable client javascript to the browser for an internal website. The receiving end strips double and single quotes when displayed. One way I have found to get around quotes is by declaring my string as a regular expression.
var x = String(/This contains no quotes/);
x = x.substring(1, x.length-1);
x;

Using String prototype:
String(/This contains no quotes/).substring(1).slice(0,-1)
Using String.fromCharCode
String.fromCharCode(72,69,76,76,79)
Generate Char Codes for this:
var s = "This contains no quotes";
var result = [];
for (i=0; i<s.length; i++)
{
result.push(s.charCodeAt(i));
}
result

In JavaScript, you can escape either type of quote with a \.
For example:
var str = "This is a string with \"embedded\" quotes.";
var str2 = 'This is a string with \'embedded\' quotes.';
In particular, your block of JavaScript code should be converted to:
var ip = "<lang:cond><lang:when test=\"$(VAR{'ip_addr'})\">$(VAR{'ip_addr'})</lang:when></lang:cond>";
In general, I always prefer to escape the quotes instead of having to constantly switch quote types, depending upon what type of quotes may be used within.

I was looking for a solution to the same problem. Someone suggested looking at https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/template_strings which proved helpful. After reading about half the article, it stated that you can create strings with the backward tick character. (`)
Try this :)
document.getElementById('test').innerHTML = `'|'|'|"|"`
<div id="test" style="font-size:3em;"></div>

You can't create a string without using a single or double quote, as even calling the String() prototype object directly still requires you to pass it the string.
Inside XML you would use CDATA, but inside JS you'll have to just escape the '\"strings\"' "\'appropriately\'"

How to add "\" character in JSON?

I want to add JSON data with the following string value:
json = "d:\xyz\abc";
This value is coming from a database at runtime. When I am going to display it in datatable, JSON formatting error is displayed. My requirement is that the above value will be displayed as it is in the datatable. Please help.

Escape it with another \:
var json = "d:\\xyz\\abc";

You'd better use a JSON library for your programming language. You don't retrieve database values directly with jquery, aren't you?
So, you'd use something like JSON.escape(my_string_from_db), or, in Ruby language I usually do my_string.to_json.
This will automatically escape everything that needs to be escaped.

Change to this:
json = "d:\\xyz\\abc";
See this question for further information

\ is the escape character in JavaScript strings, it gives special meaning to the character following the slash. Like \t is a tab character, \n is a new line. To put a backslash literal you'll need to use \\
The first backslash says the next character is going to be special, the following backslash says "oh, it's just a backslash."
