I have if(js.global.console) lookup = console.getkeys("HSOQ", lastuser);
where lastuser=system.lastuser... if entering a number it throws a
!Javascript TypeError:

What is the correct usage of console.getkeys? I inferred:


console methods
getkeys:
number console.getkeys(string keys [,maxnum]) 3.10 get one key from of a list of valid command keys, or a number between 1 and maxnum

That looks like it should work. What's the full text of the error?

It seems to work for me. Perhaps it's what you're *doing* with the lookup value. Are you getting a line number with the error? What line of JavaScript corresponds with that line number?

I suspect that the toUpperCase() is not be supported by the console.getkeys() function :-/

toUpperCase() is not supported by JavaScript Numbers. console.getkeys() can return a number or a string, depending on the user input.

I have if(js.global.console) lookup = console.getkeys("HSOQ", lastuser); where lastuser=system.lastuser... if entering a number it throws a !Javascript TypeError:

perhaps I should run a condition check similar to if(lookup == [whatever || ... keys are in getkeys)) before I lookup.toUpperCase ... though before it was lookup = readln() and there was no error

readln() returns either a string or undefined. undefined.toUpperCase() would also throw a JS exception.

You might want to use typeof in this case to be sure your variable is a string before you start treating it like a string.

Thank you, I am still learning JS/C :\ I ended up using if(isNaN(lookup)) { ... } block. I am sure typeof is more flexible :-)
