How do I add quotation marks to a JSON Object attributes for example like this:
{name:"User 01"}
so it should look like that afterward:
{"name":"User 01"}
both of them are strings

Where are you seeing the first example? Javascript Object?bozdoz– bozdoz2015-03-12 21:54:21 +00:00Commented Mar 12, 2015 at 21:54

Assuming the first example is a Javascript object, you could convert it into a JSON string using JSON.stringify:
JSON.stringify({name:"User 01"});
outputs: "{"name":"User 01"}"
Assuming String
If the first example is a string, I think you would have to parse through it with methods like split.

Sorry, I did not write it down; The important thing is, it is not a JSON object, it is a string, which is the output from JSON.stringify-ed JSON Object and the quotation marks from the attributes were deleted

Parsing via split is tricky if you want do it right, I.e. strings could contain colons or commas...
JSON.stringify(eval('{name:"User 01"}'));
Not really great but works.

Uhh, eval.. I don't like that, but anyway, that is exactly what I wanted! Thanks dude!

Jep, don't like it either but keeps you going until you find something better. Best practice is to add FIXME as a comment above. ;)
the first notation
var string = {name:"user 01"}
if you use it then you can directly access all the properties and methods of the string object
but if you use this notation :
var string = {"name":"user 01"}
then you have to use :
window.JSON.parse("'"+string+"'")
Update: Now that we have ES6, you can use template literals :
window.JSON.parse(`'${string}'`)
in order to access all the methods and properties of string object
the last notation is used generally when getting data back from php script or something like that

What JS implementation are you using that doesn't like
var obj = { "name": "user 01" }? That's a perfectly-valid JS object literal.. the quotation marks around the key are optional if the key is a valid identifier, but always acceptable.Use this:
function JSONify(obj){
var o = {};
for(var i in obj){
o['"'+i+'"'] = obj[i]; // make the quotes
}
return o;
}
console.log(JSONify({name:'User 01'}));
