JS打印的几种实现方法

1、使用IE自带的WebBrowser控件进行打印，用户无需下载该控件，但缺点是需要设置IE浏览器的安全设置才能使用，“Internet选项”-->“安全”-->“自定义级别”-->“对未标记为可安全执行脚本的ActiveX控件初始化并执行脚本”改为“启用”或者是“提示”，有些时候不同的系统、不同的浏览器版本可能设置的安全级别不一样，具体设置哪个立竿见影暂时没弄明白，刚才说的设置仅作参考我这么设置时好使过，可能换一台电脑也许又不会管用了

。

<%@ page contentType="text/html;charset=utf-8" language="java"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title>My JSP 'MyJsp.jsp' starting page</title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
	<link href="/print.css" rel="stylesheet" />
	<link href="/print.css" rel="stylesheet" media="print" />
	<style type="text/css" media=print>
		.noprint{display : none }
	</style>
	<script language="javascript">
		// 打印页面设置 
	　　function printsetup() {
		　　wb.execwb(8,1);
	　　}
		// 打印页面预览
	　　function printpreview() {
		　　wb.execwb(7,1); 
	　　} 
	　　function printit() {
		　　if (confirm('确定打印吗？')) { 
		　　		wb.execwb(6,6) 
		　　}
	　　}
		
		var HKEY_Root,HKEY_Path,HKEY_Key;
		HKEY_Root="HKEY_CURRENT_USER";
		HKEY_Path="\\Software\\Microsoft\\Internet Explorer\\PageSetup\\";
		//设置网页打印的页眉页脚为空
		function PageSetup_Null() {
			try {
				var Wsh=new ActiveXObject("WScript.Shell");
				HKEY_Key="header";
				Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"");
				HKEY_Key="footer";
				Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"");
			}catch(e){
			
			}
		}

		//设置网页打印的页眉页脚为默认值
		function  PageSetup_Default() {
			try {
				var Wsh=new ActiveXObject("WScript.Shell");
				HKEY_Key="header";
				Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"&w&b页码，&p/&P");
				HKEY_Key="footer";
				Wsh.RegWrite(HKEY_Root+HKEY_Path+HKEY_Key,"&u&b&d");
			}catch(e){
			
			}
		}
	</script>
  </head>
  
  <body>
	<DIV align=center>
	<OBJECT id="wb" height="0" width="0" classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" name="wb"></OBJECT>
	<input name="button_print" onclick="javascript:printit()" type="button" value="打印"  class="noprint"/>
	<input name="button_setup" onclick="javascript:printsetup();" type="button" value="打印页面设置" class="noprint"/> 
	<input name="button_show" onclick="javascript:printpreview();" type="button" value="打印预览" class="noprint" />
	<input type="button" value="清空页码"  onclick="PageSetup_Null()" class="noprint"/>
	<input type="button" value="恢复页码"  onclick="PageSetup_Default()" class="noprint"/>
	</DIV>
           这些文字就是要打印的内容！
  </body>
</html>

2、区域打印

<%@ page contentType="text/html;charset=utf-8" language="java"%>
<%
	String path = request.getContextPath();
	String basePath = request.getScheme() + "://"
			+ request.getServerName() + ":" + request.getServerPort()
			+ path + "/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>
	<head></head>
	<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>
	<body>
		<form id="WebForm1" method="post">
			<center>
				本部分内容不被打印
			</center>
			<!--startprint-->
			<div align="center">
				<table>
					<tr>
						<td>
							打印打印打印打印打印打印打印打印
						</td>
					</tr>
				</table>
			</div>
			<!--endprint-->
			<center>
				本部分内容不被打印
			</center>
			<div align="center">
				<input type="button" name="print" value="预览并打印" onclick="preview()">
			</div>
		</form>
	</body>
</html>

3、通过jQuery实现打印

<%@ page contentType="text/html;charset=utf-8" language="java"%>
<%@ page import="com.trht.session.SessionMng"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

	SessionMng sessionmng = (SessionMng) request.getSession().getAttribute("sessionmng");
	String ctxpath = request.getContextPath();
	if("/".equals(ctxpath)){
		ctxpath = "";
	}
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <base href="<%=basePath%>">
    
    <title></title>
    
	<meta http-equiv="pragma" content="no-cache">
	<meta http-equiv="cache-control" content="no-cache">
	<meta http-equiv="expires" content="0">    
	<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
	<meta http-equiv="description" content="This is my page">
	<!--
	<link rel="stylesheet" type="text/css" href="styles.css">
	-->
	<script language="JavaScript" type="text/javascript" src="<%=ctxpath%>/javascript/jquery/uploadify/jquery-1.4.2.min.js" ></script>
	<script language="JavaScript" type="text/javascript" src="<%=ctxpath%>/javascript/jquery/uploadify/jquery.PrintArea.js" ></script>
	<script>
		$(document).ready(function(){
			$("input#biuuu_button").click(function(){
				$("div#myPrintArea").printArea();
			});
		});
	</script>
  </head>
  
  <body>
    <div id="noPrintArea">这部分内容不打印</div>
	<div id="myPrintArea">只打印这部分内容</div>
	<input id="biuuu_button" type="button" value="打印"></input> 
  </body>
</html>
