代碼如下，簡單實用。因為需要用到這個東西，所以很無恥的拾人牙慧，收藏一下。
<!DOCTYPE html><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><title>無標題文檔</title><script type="text/javascript"> function doPrint() { 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></head> <body><p>1</p><p>2</p><!--startprint--><!--注意要加上html裡star和end的這兩個標記，之前沒加，一直沒效果，誰叫咱們菜呢~--><h1>列印標題</h1><p>列印內容~~</p><!--endprint--><button type="button" onclick="doPrint()">列印</button><p>1</p><p>2</p></body></html>
