Script to list subnodes under a container node

Question: How do I list sub nodes from a container node for building a menu for instance?

Answer: The following script (serverside Javascript in the SiteVision Script portlet) demonstrates the solution

// Get utilities in the SiteVision Public API
var utils = request.getAttribute("sitevision.utils");
var resourceLocatorUtil = utils.getResourceLocatorUtil();
var nodeIteratorUtil = utils.getNodeIteratorUtil();
var linkRenderer = utils.getLinkRenderer();

// Get a container node
var sitePage = resourceLocatorUtil.getSitePage();

// Get subnodes
var menuItemsIterator = nodeIteratorUtil.getMenuItems(sitePage);

// List subnodes and render them as a link
out.println("<ul>");
while (menuItemsIterator.hasNext())
{
   var menuItem = menuItemsIterator.nextNode();
  
   linkRenderer.update(menuItem);
   out.println("<li>" + linkRenderer.render() + "</li>")  
}
out.println("</ul>");
