Javascript helllp~

[DNS]

I was being all wierd and twitchy and decided to make a little genthing for myself. I basically modified one of the generators on seventh sanctum, but now it's acting up~

Front page is nifty and tells me exactly where the problem is; line 2021. the problem is that line 2021 ISN'T the java i changed (basically the contents of the arrays) but a function of the java itself.

I don't know jack shit about javascript, so naturally I'm lost. I've tried the script off of 2 other generators but I still no get it to worky.

code as is follows~ -
<hr>

function GenNumber (nRange)
{
var iNumGen
iNumGen = Math.round((Math.random() * nRange));

return iNumGen;
}

function GetFrom(aArray)
{
var undefined
var sReturn
sReturn = aArray[GenNumber(aArray.length)];
if (sReturn == undefined)
{
sReturn = GetFrom(aArray)
}
return sReturn
}

function GetArray(sArrayName)
{
var bHold = true
//alert(sArrayName)
for (var intLooper=0;intLooper <aVocab.length;intLooper++)
{
if (aVocab[intLooper][0]==sArrayName) <Problem> -1)
{
iTagStart = sLine.indexOf("<iTagEnd> - 1)
{
sLine = ScanLine(sLine)
}

return sLine;
}

function GenPlot()
{
sLine = GetFrom(GetArray("BASE"));

sLine = ScanLine(sLine)

document.GENFORM.STORY.value = sLine;
}
//-->

<hr>

The error message says that 'aVocab[...].0' is a null or not an object.
does anyone know the problems?

Edit: -stare- it's misbehaving. that's as good as the code's gonna get i guess-- the furry character gen in seventh sanctum. the particular problem line is such:
If (aVocab[intlooper][0]==sArrayName)

I can't say I know too much about Java, but a couple things stand out to me as possible problems...

if (aVocab[intLooper][0]==sArrayName) <Problem> -1)
{
iTagStart = sLine.indexOf("<iTagEnd> - 1)

In the first line, you have one opening bracket and two closing brackets...
And in the second line, you have a quote mark before iTagEnd but not afterwards, and for code to work you always need two quote marks...

iTag isn't in the original code. :/ I think the bbcode added it when i pasted it up here. As for the brackets.. they worked for seventh sanctum, but i noticed that too. Did nothing when i tried to change it, though. X.x Cept caused a different error, but yes.
whee~ thanks, though,

It sounds like you have an array bounding error.

Where do you define aVocab? Is that all of the code? Because it looks like you don't define it there. If that's not all the code, look at where aVocab is initially created and check to make sure you allocated space for the second dimension of the array. Because an error comment like:

"aVocab[...][0] is null or does not exist" means that the second index is invalid and may not have been allocated.

aaah, i vagually can trasnlate that speak from when i took c++.

I.. don't know if i made the array. :/ that might very well be the problem... could anyone tell me what to do/look for in that sense?

[DragonFlight]

Look for a statement:

var aVocab

at least, followed somewhere by:

aVocab = (some javascript that defines an array)

I don't know Javascript in particular so I don't know how it defines an array normally.

Squeee~ -hugs- thanks, DF. I got the code working.

[DragonFlight]

Yay! What'd the problem end up being?

[DNS]

An extra two lines of code at the top of the first array, which I wouldn't've caught unless you told me to check for the vars thingum. -hugs- thankyou
