This property determines whether JavaScript and VBScript are enabled.

By default client side script such as JavaScript is disabled when rendering HTML documents.

This is done for good security reasons and we strongly recommend that you do not change this setting.

However if you are sure that your source documents do not pose a security risk you can enable Script using this setting.

The following example shows one method of crawling and transferring an entire site to PDF. Here we use JavaScript to determine the links present on the page. However you could equally well use the HtmlCallback to do the same thing.

[C#]
Doc theDoc = new Doc();
string theURL = "http://www.fbi.gov/";
// Set HTML options
theDoc.HtmlOptions.AddLinks = true;
theDoc.HtmlOptions.UseScript = true;
theDoc.HtmlOptions.PageCacheEnabled = false;
// JavaScript is used to extract all links from the page
theDoc.HtmlOptions.OnLoadScript = "var hrefCollection = document.all.tags(\"a\");" +
  "var allLinks = \"\";" +
  "for(i = 0; i < hrefCollection.length; ++i) {" +
  "if (i > 0)" +
  "  allLinks += \",\";" +
  "allLinks += hrefCollection.item(i).href;" +
  "};"+
  "document.documentElement.abcpdf = allLinks;";
// Array of links - start with base URL
ArrayList links = new ArrayList();
links.Add(theURL);
for (int i = 0; i < links.Count; i++) {
  // Stop if we render more than 20 pages
  if (theDoc.PageCount > 20)
    break;
  // Add page
  theDoc.Page = theDoc.AddPage();
  int theID = theDoc.AddImageUrl(links[i] as string);
  // Links from the rendered page
  string allLinks = theDoc.HtmlOptions.GetScriptReturn(theID);
  string[] newLinks = allLinks.Split(new char[] {','});
  foreach (string link in newLinks) {
    // Check to see if we allready rendered this page
    if (links.BinarySearch(link) < 0) {
      // Skip links inside the page
      int pos = link.IndexOf("#");
      if (! ( pos > 0 && links.BinarySearch(link.Substring(0, pos)) >= 0)) {
        if (link.StartsWith(theURL)) {
          links.Add(link);
        }
      }
    }
  }
  // Add other pages
  while (true) {
    theDoc.FrameRect();
    if (!theDoc.Chainable(theID))
      break;
    theDoc.Page = theDoc.AddPage();
    theID = theDoc.AddImageToChain(theID);
  }
}
// Link pages together
theDoc.HtmlOptions.LinkPages();
// Flatten all pages
for (int i = 1; i <= theDoc.PageCount; i++) {
  theDoc.PageNumber = i;
  theDoc.Flatten();
