Create object by string

Question

This is a quick question, I hope you could help me with.

How can I use a string to navigate into a object?

If I have this:

var string = something;

And a object like this:

var this = {
    something: {
        other: "okay"
    }
};

How can I then use the string to do like this:

this.+string+.other

Which would be the same as:

this.something.other

?? Not a quick one maybe, but do you understand where I'm going?? :-)

careful with using this as a variable name. Strange things will happen, or nothing will happen at all! — Hidde

Try using [] below,

var _this = {
    something: {
        other: "okay"
    }
};

_this[string].other

Note: changed var name to _this as var this = <..something..> will throw you an error. Also this means currect execution object/window object in javascript.

+1 I also think that using this as a variable name is not that good.

Thanks for the quick reply. The variables were just for the sake of example, but I should have been more careful :)

Use square bracket notation:

var this[something].other
