Hi, I have a variable called nameID. This variable holds the name of another variable which is an array. Sometimes the variable that is held in nameID is non-exsistent ie. "undefined". How can I test this? I've tried typeof(eval(nameID))) but that returns "object". I need a way to see whether the variable that is held in nameID is exsistent. Can anyone help me? Thank you.
