Question

I’m trying to use this script

function padNumber(num, len){
    var str = ''+num;
    while(str.length < len){
      str = '0' + str;
      }
      return str;
}

in my xlst file but I get this error when trying to debug.

XslLoadException
—————- XSLT compile error.

XmlException
———— Name cannot begin with the ‘ ‘ character, hexadecimal value 0x20. Line 522, position 27.

line 522 is

while(str.length < len){

Any suggestions?

For the sake of redability, you can also put the Javascript code within a CDATA section. In this case you don’t need to change the JS code.

However, the text in a CDATA section must not contain the string "]]>". If so, this string must be split between two consecutive CDATA sections.

I believe that it is not too-likely for a typical JS code to contain that string, but one must be aware of such possibility, regardless how slim it is.
