How to add "\" character in JSON?

Question

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.

How are you creating your JSON? – deceze Dec 13 '11 at 12:04 — deceze, Dec 13 '11 at 12:04

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.

\ 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."
