This method evaluates the JSON in the string and returns the resulting object. If the optional sanitize parameter is set to true, the string is checked for possible malicious attempts and eval is not called if one is detected.

Syntax

string.evalJSON([sanitize = false]);

Return Value

Returns a string.

         function showResult() {
            var str = '{ "name": "Violet", "occupation": "character" }';
            var person = str.evalJSON();
            alert( "Name :" + person.name);
            alert( "Occupation :" + person.occupation);
         }
      </script>
