Not a Problem
When I run Javascript while I am editing using the offline version of Geogebra 5.0, the string length property requires the () at the end in order to (incorrectly) function properly, but when you upload the file to Geogebratube, it will only work when the () are removed. See code and comments below.
function ggbNoSpaces (s) {
snew = "";
slen = s.length(); // this code must be run when editing offline in Geogebra 5.0
// slen = s.length; // this code must be run when uploaded into GeogebraTube
for (i = 0; i < slen; i++) {
if (s.substr(i, 1) != " ") {
snew += s.substr(i, 1);
}
}
return snew;
}
The same problem 
I don't think it's a bug.
that because all the variable will be treat as an "Object", not a "String。
so, you need add this statement at the beginning of the function "ggbNoSpaces":
here, in ggb5 is ok.
please post your file to check the problem.
What version of GeoGebra 5 are you using?
