Typecasting in Javascript

Question

How to convert the following Java code to JScript:

return ((IPOSBasket) basket).getOriginalCashierID();

When executing the above code in Java, it works fine. But if I try to execute as a JScript, I am getting NULL value.

Are you talking about [JScript](http://en.wikipedia.org/wiki/JScript) or [Javascript](http://en.wikipedia.org/wiki/JavaScript)? — mthmulders, Jul 10 '13 at 08:07
If it is jScript, are you using it to compile .net assemblies? http://en.wikipedia.org/wiki/JScript_.NET That jScript is typed. Ecma javascript and jscript in IE are not typed so there is no need for conversion (unless you need string to number). — HMR, Jul 10 '13 at 08:13
In case you try to run this script in a browser then `return basket.getOriginalCashierID();` will do. — HMR, Jul 10 '13 at 08:17

At the risk of getting downvotes XD

Java and Javascript are similar like Car and Carpet are similar.

You shouldn't need to cast anything, how are you getting the basket variable?

Also, as a good practice don't do any operations in a return statement, it sometimes hides errors/problems in code and harms readability.

So if it is JScript:

var basket : IPOSBasket = IPOSBasket(x); // this is made up, don't know what you are doing here.
var originalCashierID = basket.getOriginalCashierID();
return originalCashierID;

As mentioned by HMR in comment, the following line works fine:

return basket.getOriginalCashierID();
