Is Javascript a security threat?

The IT dept of a potential client has identified some of the Javascript in my Webhelp output as a potential security threat for cross-site scripting.

Could someone please answer the following questions about the following code block?

• What is its purpose?

• Can all, or part of it be deleted? (And if so, please provide excruciatingly detailed instructions for removing javascript or minimising it in my output files.)

• Do you think that the javascript in webhelp constitutes a security threat?

I am using RoboHelp 8 & don't know nothin' bout no javascript. This objection has never arisen before.

The code block (and especially the if statements about two different windows)

if (window.gbWhTopic)
{
var strUrl = document.location.href;
var bc = 0;
var n = strUrl.toLowerCase().indexOf("bc-");
if(n != -1)
{
  document.location.href = strUrl.substring(0, n);
  bc = strUrl.substring(n+3);
}

if (window.addTocInfo)
{

}
if (window.writeBtnStyle)
  writeBtnStyle();

if (window.writeIntopicBar)
  writeIntopicBar(0);

if (window.setRelStartPage)
{
setRelStartPage("Acco_3.htm");

  autoSync(1);
  sendSyncInfo();
  sendAveInfoOut();
}
}
else
if (window.gbIE4)
  document.location.reload();

Thanks for any enlightenment,

John
