Is there any possibility to do it without using eval()?

Answer 1

You can access the objects properties like:

myObject['property_name']

Try:

var obj = {};
obj.foo = 'bar';
var propName = 'foo';
console.log(obj[propName]);

Of cource you can:

​(function(){
    var obj = {};
    obj.foo = 'bar';

    var key = 'foo';

    document.write(obj[key]);
})()​
