javascript string to object

Question

How to apply string object value to a variable Ex.

var str='{a:"www"}' 

Now how to set

var obj={a:"www"} 

I try eval() but not working

Answer 1

eval should work, and it's actually a MDN solution, not to mention that your string is not a valid JSON, so eval is your only option (if you don't want to include a library for that).

var str='{a:"www"}'; var obj=eval("("+str+")"); console.log(obj); 

Quick test in Chrome Dev Tool:

eval("("+'{a:"www"}'+")") Object     a: "www"     __proto__: Object 

Just remember to wrap your string in parenthesis and assign it outside eval and it'll be (relatively) safe.
