js 打印
1、借助插件打印（ps:该插件也是通过iframe进行打印）
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>print page demo 3</title>
<script type="text/javascript" src="../jquery/jquery-1.11.2.min.js"></script>
<script type="text/javascript" src="jquery.PrintArea.js"></script>
</head>
<body>
<script>
$(document).ready(function() {
$("input#biuuu_button").click(function() {
$("div#myPrintArea").printArea();
});
});
</script>
<input id="biuuu_button" type="button" value="打印"></input>
确定是打印局部？？？
<div id="myPrintArea">.....文本打印部分.....</div>
</body>
</html>
2、window.open打开新页面进行打印
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>print page demo</title>
<script type="text/javascript" src="../jquery/jquery-1.11.2.min.js" ></script>
<script type="text/javascript">
function printPage() {
var newWindow = window.open("", "_blank"); //打印窗口要换成页面的url
//绘制html
newWindow.document.write($("#printArea").html());
//打印后关闭窗口
newWindow.document.close();
newWindow.print();
newWindow.close();
}
</script>
</head>
<body>
<div><button type="button" onclick="printPage()">打印</button></div>
<div id="printArea">
<div class="print_title">标题</div>
<div class="print_content">打印的内容</div>
</div>
</body>
</html>
3、iframe进行打印
function do_print(id_str) //id-str 打印区域的id
{
var el = document.getElementById(id_str);
var iframe = document.createElement('IFRAME');
var doc = null;
iframe.setAttribute('style', 'position:absolute;width:0px;height:0px;left:-500px;top:-500px;');
document.body.appendChild(iframe);
doc = iframe.contentWindow.document;
// 引入打印的专有CSS样式，www.111Cn.net根据实际修改
doc.write("<LINK rel="
stylesheet " type="
text / css " href="
css / print.css ">");
doc.write('<div>' + el.innerHTML + '</div>');
doc.close();
iframe.contentWindow.focus();
iframe.contentWindow.print();
if(navigator.userAgent.indexOf("MSIE") > 0) {
document.body.removeChild(iframe);
}
}
// var iframe = document.getElementById('printPage');
// 异步加载，导致内容还没获取就打印了
// iframe.onload = function() {
// iframe.contentWindow.focus();
// iframe.contentWindow.print();
// }
