Hi, I have a whole string of values separated by a delimiter(e.g. space) like:
Hello World How Are You
My codes are as below:

var param = _arrGlobal.substring(_arrGlobal.lastIndexOf(' ') + 1);
alert(param);

How can I retrieve the word "You" which is after the last delimiter?
I have tried indexOf() or lastIndexOf() but cannot really do it.

What I have tried:

1. Tried indexOf() and lastIndexOf().

I have tried to inspect. Error saying substring is not a method.

Found out to be missing conversion for the _arrGlobal.
var param1 = _arrGlobal.toString();
var param = param1.substring(param1.lastIndexOf(' ') + 1);
alert(param);

Thank you sir for your info. I have found the root cause error on the above question. It is due to I must convert the _arrGlobal into string(e.g. _arrGlobal.toString()) before substring it. Then the error message would disappear. Anyway, I will mark your answer as solution here. Thank you again.
