Return Json, But It Includes Backward Slashes "\", Which I Don't Want

Return Json, but it includes backward slashes “\”,

Why are you returning a json string from your web api?

It knows how to serialize objects into JSON's automatically.

Anyway to convert a string json into a json use JSON.parse:

var json = "{\"cid\":1,\"model\":\"WT50JB\",\"detail\":\"sdf??\",\"unit\":2,\"time_in\":\"2012-12-11T19:00:00\",\"time_out\":\"2012-12-12T13:00:06.2774691+07:00\",\"time_used_dd\":0.0,\"time_used_hh\":0.0}";
var parsedJSON = JSON.parse(json);

alert(parsedJSON.cid); // 1

Remove Backslashes from Json Data in JavaScript

Your string is invalid, but assuming it was valid, you'd have to do:

var finalData = str.replace(/\\/g, "");

When you want to replace all the occurences with .replace, the first parameter must be a regex, if you supply a string, only the first occurrence will be replaced, that's why your replace wouldn't work.
