使用JS打印,
看

<script language="javascript">
function preview()
{
bdhtml=window.document.body.innerHTML;
sprnstr="<!--startprint-->";
eprnstr="<!--endprint-->";
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));
window.document.body.innerHTML=prnhtml;
window.print();
}
</script>
function preview()
{
bdhtml=window.document.body.innerHTML;
sprnstr="<!--startprint-->";
eprnstr="<!--endprint-->";
prnhtml=bdhtml.substr(bdhtml.indexOf(sprnstr)+17);
prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));
window.document.body.innerHTML=prnhtml;
window.print();
}
</script>
这段代码,他是打印
<!--startprint-->和<!--endprint-->
这个标记之间的网页内容。
所以网页中要包含这个2个标签才行···
但打印功能还有很多不知道怎么实现,比如:怎么去页眉页脚?怎么取消浏览功能?
希望知道的告诉下
