js或jquery实现页面打印可局部打印

js或jquery实现页面打印(局部打印)

1、js实现(可实现局部打印) 

<html> 
<title>js打印</title> 
<head></head><body> 
<input id="btnPrint" type="button" value="打印" onclick="javascript:window.print();" /> 

<input id="btnPrint" type="button" value="打印预览" onclick=preview(1) /> 
<style type="text/css" media=print> 
.noprint{display : none } 
</style> 


<p class="noprint">不需要打印的地方</p> 

<script> 
function preview(oper) 
{ 
if (oper < 10) 
{ 
bdhtml=window.document.body.innerHTML;//获取当前页的html代码 
sprnstr="<!--startprint"+oper+"-->";//设置打印开始区域 
eprnstr="<!--endprint"+oper+"-->";//设置打印结束区域 
prnhtml=bdhtml.substring(bdhtml.indexOf(sprnstr)+18); //从开始代码向后取html 

prnhtml=prnhtml.substring(0,prnhtml.indexOf(eprnstr));//从结束代码向前取html 
window.document.body.innerHTML=prnhtml; 
window.print(); 
window.document.body.innerHTML=bdhtml; 
} else { 
window.print(); 
} 
} 
</script> 
<p>XXXXX</p> 
<!--startprint1-->要打印的内容<!--endprint1--> 
</body> 
</html> 
2、调用windows底层打印,报安全警告,不建议使用(不支持局部打印)

<HTML> 
<HEAD> 
<TITLE>javascript打印-打印页面设置-打印预览代码</TITLE> 
<META http-equiv=Content-Type content="text/html; charset=gb2312" /> 
<SCRIPT language=javascript> 
  function printsetup(){ 
  // 打印页面设置 
  wb.execwb(8,1); 
  } 
  function printpreview(){ 
  // 打印页面预览 
     
  wb.execwb(7,1);       
     
  } 

  function printit() 
  { 
  if (confirm('确定打印吗?')) { 
  wb.execwb(6,6); 
  } 
  } 
  </SCRIPT> 
</HEAD> 
<BODY> 

<DIV align=center> 
<OBJECT id=wb height=0 width=0 
classid=CLSID:8856F961-340A-11D0-A96B-00C04FD705A2 name=wb></OBJECT> 
<INPUT onclick=javascript:printit() type=button value=打印 name=button_print /> 
<INPUT onclick=javascript:printsetup(); type=button value=打印页面设置 name=button_setup /> 
<INPUT onclick=javascript:printpreview(); type=button value=打印预览 name=button_show /> 
一按开始的减肥了卡时间段 
</DIV> 
</BODY> 
</HTML> 
3、jQuery实现(支持局部打印)
<html> 
<head> 
<script type="text/javascript" src="jquery-1.6.4.js"></script> 
<script> 
$(function(){ 
$("input#biuuu_button").click(function(){ 
$("div#myPrintArea").printArea(); 
}); 
</script> 
</head> 
<body> 
<input id="biuuu_button" type="button" value="打印"></input> 
<div id="myPrintArea">.....文本打印部分.....</div> <div class="quote_title">引用</div><div class="quote_div"></div> 
</body> 
</html>
