Remarks

This event is usually used with the onbeforeprint event. use the onbeforeprint event to make changes to the document just before it prints or previews for printing. use the onafterprint event to undo those changes, reverting the document back to its pre-print or pre-preview state.

DHTML代码范例

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 page 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].bExpandedForPrinting))
{
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;
}
}
