一．用JS自带函数打印
<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-->
再加个打印按纽 onclick=preview(1)
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>
3jQuery实现（支持局部打印）
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="jquery.PrintArea.js"></script>
<script>
$(document).ready(function(){
$("input#biuuu_button").click(function(){
$("div#myPrintArea").printArea();
});
});
</script>
<input id="biuuu_button" type="button" value="打印"></input>
<div id="myPrintArea">.....文本打印部分.....</div>
Query插件PrintArea完整方法如下：
- (function($) {
- var printAreaCount = 0;
- $.fn.printArea = function()
- {
- var ele = $(this);
- var idPrefix = "printArea_";
- removePrintArea( idPrefix + printAreaCount );
- printAreaCount++;
- var iframeId = idPrefix + printAreaCount;
- var iframeStyle = 'position:absolute;0px;height:0px;left:-500px;top:-500px;';
- iframe = document_createElement_x('IFRAME');
- $(iframe).attr({ style : iframeStyle,
- id : iframeId
- });
- document.body.a(iframe);
- var doc = iframe.contentWindow.document;
- $(document).find("link")
- .filter(function(){
- return $(this).attr("rel").toLowerCase() == "stylesheet";
- })
- .each(function(){
- doc.write('<link type="text/css" rel="stylesheet" href="' +
- $(this).attr("href") + '" >');
- });
- doc.write('<div class="' + $(ele).attr("class") + '">' + $(ele).html() + '</div>');
- doc.close();
- var frameWindow = iframe.contentWindow;
- frameWindow.close();
- frameWindow.focus();
- frameWindow.print();
- }
- var removePrintArea = function(id)
- {
- $( "iframe#" + id ).remove();
- };
- })(jQuery);
