## Examples

This example uses the onafterprint event to return the document to its pre-print state. In this case, because the onbeforeprint event handler makes all currently hidden sections of the document visible for printing, the onafterprint event sets those sections back to hidden.

function window.onafterprint()
    // Walk through all the elements in the doc with CLASS="expanded"
    // and set it to "collapsed" if expanded just for
    // printing.
   var coll = document.all.tags("DIV");
   if (coll!=null)
      for (i=0; i<coll.length; i++)
         if ((coll[i].className == "expanded") &&
           coll[i].className = "collapsed";
           coll[i].bExpandedForPrinting = false;
function window.onbeforeprint()
    // Walk through all the elements in the doc with CLASS="collapsed"
    // and set it to "expanded" just for printing.
   var coll = document.all.tags("DIV");
   if (coll!=null)
      for (i=0; i<coll.length; i++)
         if (coll[i].className == "collapsed")
           coll[i].className = "expanded";

        // After printing, make sure to set
        // CLASS="collapsed" only for those that were
        // expanded just for printing.
           coll[i].bExpandedForPrinting = true;
         else if (coll[i].className == "expanded")
            coll[i].bExpandedForPrinting = false;
