Help me find bug Options

[denmarks]

I am working on a program a step at a time. A rarely do HTML and Javascript from scratch so I am always forgetting details.
So far this page should convert to binary. When the page appears just enter 6 numbers less than 64. Click enter and an alert should display the binary. I am getting an error that it can't find the function. I am sure it is something simple but Firefox is no help.

I get 2 errors
nimRoutine not found and ; missing.

I sure it is something simple but I can't find the error.

Two things jump out. It's 'if', not 'If', lower case. You shouldn't use semicolon at the end of function braces. That's just at the end of statements.

With those changes, at least it does something and the errors go away. Alas it returns 0 for everything. But a step in the right direction anyway.

I found the problem. The VAR on the subtables.

That's not the only change you made.

Before

CODE

nimTable = new Array(5);
nimTable[0] = new Array(5);
nimTable[1] = new Array(5);
nimTable[2] = new Array(5);
nimTable[3] = new Array(5);
nimTable[4] = new Array(5);
nimTable[5] = new Array(5);

Now

CODE

var nimTable = new Array(5);
var nimTable[0] = new Array(5);
var nimTable[1] = new Array(5);
var nimTable[2] = new Array(5);
var nimTable[3] = new Array(5);
var nimTable[4] = new Array(5);
var nimTable[5] = new Array(5);

Using var when you declare the array is fine, but not when you set the individual values.

Now you tell me!

Sorry. I'm still trying to get back into the swing of things. Now the problems are just logic.

Just joking. Happens all the time.

Thanks for your help. I am sure I will be back. I got the convert to binary working fine. That is all for today. I assume you know about the game of Nim. The algorithm is pretty simple. Converting it to code it what is tricky. I first programmed it for the IBM 1620 about 50 years ago. I thought I would create a Javascript. I did not like what was available.

No, I didn't. But I've read a little about it now.
