Problem description:in my guide on wolves this is the script using HTML but when i use it whenever i switch from the wolves to the message board or something to something(whenever i move from one place to another) i get a error:
An error has occurred in the script on this page
line: 80
Char: 1
Error: Unknown runtime error
Code: 0
UR:: file:///C:/Users/Home/Documents/BYOND/cache/2571d67c.htm

Use Control+G to find line 80 and show us which one it is.
#2 May 26 2012, 9:07 pm
Bit more helpful info:
on line its always between case cmd and break;
#3 May 26 2012, 9:08 pm
78:"<center>Notice:Exposing the wolf code to any outsider will result in your termination from the pack and your country being destroyed.</center>";
79:document.getElementById("span").innerHTML = body2;
80:
81:break;

82:case "cmd3":
#4 May 26 2012, 9:17 pm
i seemed to left out a part

also this is what the new errors are:

51:case "cmd2":

83:case "cmd3":

157:case "cmd4":
158:
159:document.getElementById(span").innerHTML = body2;

break;
177:}
178:
179:}
180:</script>



if the line hade nothing on it i went outwards from it til i hit something that could be a problem

Upon some research, it looks like strings cannot be used in switch statements.
#6 May 26 2012, 9:31 pm
meaning i cant use
switch(menu.options[menu.selectedIndex].value)?
#7 May 26 2012, 9:31 pm
or
document.getElementById("span").innerHTML = body2;
#8 May 26 2012, 9:32 pm
It means you cannot use:

case "cmd2":


You'll need to use integers or something.
#9 May 26 2012, 9:39 pm
i still get the same error when i switch to if statements
#10 May 26 2012, 9:40 pm
Then I'm not sure.
#11 May 26 2012, 9:49 pm
:/
#12 May 26 2012, 10:09 pm
i found the problem:
document.getElementById("span").innerHTML
but i still dont know how to fix
#13 May 26 2012, 10:18 pm (Edited on May 26 2012, 10:32 pm)
 
document.getElementById();

That is a method to grab an element according to it's ID. You are telling it to get an element with the 'span' ID, but thats not going to work as span is a reserved word since it is an actual element itself. Assign it a different ID and try it.

Edit: After reading a little bit, I'm not sure the words are reserved. Do you actually have an element with the 'span' ID? That function only looks for ID's, if you want to single out an element that doesn't have an ID you'll need a different function and a for loop.

var a = document.getElementByTagName('span'), b;
for(x=0;x<a.length;x++){
if(a[x].innerHTML.match(/regexp/g)){
b = a[x].innerHTML;
}
}


If the element has a class, then do like..

var a = document.getElementByTagName('span'), b;
for(x=0;x<a.length;x++){
if(a[x].className == "className"){
b = a[x].innerHTML;
}
}
#14 May 26 2012, 10:27 pm
ugh same error dont spose "text1" is reserved too?
#15 May 26 2012, 10:41 pm
:/ is that the only way?
also is that byonf or html coding?
#16 May 26 2012, 10:44 pm
Thats Javascript, which you were using there, notice the 
<script type="text/javascript">


If you don't know how to get what I gave you working, I'm not sure what to tell you.. it's good to invest in some knowledge about Javascript. Is this for a game you're programming?
#17 May 26 2012, 10:50 pm
nope :P
#18 May 26 2012, 10:56 pm
Error: Object doesnt support propertty or method 'getElementByTageName'
