The following javscript code helps you determine if the page you are trying to print has loaded completely. This prevents users from printing partialy loaded pages. This problem occurs when a visitor tries to print a page and a page suitable for printing is generated by the browser.
This is the button that upon click prints the page:
<form name="xform"><input type="button" value="print"
onclick="self.print()"></form>This is the code that check to see if the page has loaded:
<html>
<head>
<script language="javascript">
var doneloading = false;
function printpage()
{
if(doneloading)
{
window.print();
}
else
{
alert('page is not done loading yet! please wait and try again.')
}
}
function finishloading()
{
doneloading=true;
}
</script>
</head>
<body>
.. ...
<a href="printpage()"><img alt="print page"
src="images/button-image.gif" border="0"></a>
</body>
</html>
... ..
