Is it possible to convert string to literal object array?

Question

var vString = "{ "var1":"varA", "var2":"varB", "var3":"varC" }";

var literalArray = vString;

console.log(literalArray["var1"]); // = varA

How can string be converted to a literal array?

That string is syntactically incorrect, and if it weren't it would be the JSON representation of an object but not an array. — Pointy

Modify your code as given below:

var vString = '{ "var1":"varA", "var2":"varB", "var3":"varC" }';

var literalArray = vString;

console.log(JSON.parse(literalArray)["var1"]);

Is it possible without JSON?

@CPLUSPLUS no. And it's not an array.

@CPLUSPLUS you may need to write your own parsing function for that. I see no harm in using JSON.parse as it's in-built in javascript.

If JSON.parse isn't available, eval will work, but is considered to be a very bad practice when not necessary.

This will work for you...

var string = '{"var1":"varA", "var2":"varB", "var3":"varC" }';
var objectArray = (new Function("return " + string+ ";")());
console.log(objectArray.var1);

@CPLUSPLUS, i don't think so,.. this is working for this simple string = "0,1,2"; also and it will split the string from comma's , only...
