: Ok - a more detailed code snippet:

: var aFolders = new Array();
: var regE = /\\/g;
:
: function GetFolderList(folderspec){
: var f, fc;
: f = fso.GetFolder(folderspec);

: aFolders = new Array();
: for (; !fc.atEnd(); fc.moveNext()){
: aFolders[i] = "" + fc.item();
: i++;
: }
: }
: ..
: for (i=0;i<aFolders.length;i++){
: strTmp = aFolders[i].toString();
: strtTmp = strTmp.replace(regE,"/");
: strHtml = "<a href='" + strTmp + "' onClick=showFiles(" + strTmp + ")>"
+
: strTmp + "</a><br />";
: fldr1.innerHTML=fldr1.innerHTML + strHtml;
: }

: This code results in an alert-window: missing ")"

If you get an error message telling you it expected ')' then that means the
line with the error is not complete since all of your ( and ) line up and it
is generally the line previous to that or somewhere preceding in that
function. The line is trying to terminate prematurely. You need to show
the relevant code, not interpreted, probably the whole function, with
passing argument values and the expected result. If your parens line up,
and if the string is valid, then stop chasing them. They are not related to
the problem you're having. Alerting expected values along the way will help
you locate the problem.
alert('Debug0: a=' + a + ' expected: somevalue'); // debug0
Generally when I get the error you're getting it is because I'm mixing ' and
" and they are either reversed or not paired.
You can also pull out a section you think is not working and create a temp
file to work on that routine and then plug it back in when you've solved the
issue.
Looking at above, is fso global?
var aFolders = new Array();
var regE = /\\/g;
function GetFolderList(folderspec){
var f, fc;
f = fso.GetFolder(folderspec);
fc = new Enumerator(f.SubFolders);
i=0;
aFolders = new Array();
for (; !fc.atEnd(); fc.moveNext()){
aFolders[i] = "" + fc.item();
i++;
}
}
Where is:
fso = new ActiveXObject("Scripting.FileSystemObject");
Why is aFolders defined twice as an array? It's already global.
What is the value of folderspec?
