第一种是所见即所得的:

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(); //prnform.htext.value=prnhtml; //prnform.submit(); //alert(prnhtml);
