Combine strings to call on array?

[ChrisDos]

I am trying to use a input to get a value of an object. like if I type "sunday" I would get

object.sundayCol

is there a way to do that?

[JMRKER]

How do you plan on getting the input?

Are you typing in the word or can it be a button (radio, checkbox or dropdown) selection?

You can access object properties using square brackets, but you should do a check that the property exists before trying to access it.

var day = "sunday";
object[day + "Col"];
