}
实现页面(主要代码):
<script language="javascript">
printContent("title","PRINT","FIXED");//PRINT:直接打印 SELECT:选择打印机 PREVIEW:打印预览。FIXED:固定 ALL:100%。
</script>
打印数量比较多的情况,可以这样:
var len=${fn:length(list)};
var isIE = (navigator.userAgent.indexOf('MSIE')>=0) || (navigator.userAgent.indexOf('Trident')>=0);
if(len>200 && isIE){
iePrint("wb","PRINT");
}
else{ printContent("title","PRINT","FIXED"); }
此处的list用来判断数量,如从控制器拿到的list:
<c:forEach var="item" items="${list}" varStatus="s">.....</c:forEach>!!结束!!
页面中,还需插入下面一个标签,方便调用ActiveX控件。
<
OBJECT
classid
=
"CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"
height
=
0
id
=
wb
width
=
0
id
=
wb
name
=
wb
></
OBJECT
>
注:此处的classid是ie打印的类id。
<object>元素可以在页面中嵌入ActiveX控件.我们只需把ActiveX控件的classID插入到classid特性中就可以了。
注意要先到官网上下载:install_lodop32.exe和install_lodop64.exe。
这里的做了second.js的修改。可以不用这个js。
下面是个简单的预览打印页面:
1 <!DOCTYPE html>
2 <html>
3 <head>
4 <title>print</title>
5 <script src="./web/js/LodopFuncs.js"></script>
6 <script type="text/javascript" language="javascript">
7 function init(){
8 var LODOP=getLodop(document.getElementById('LODOP_OB'),document.getElementById('LODOP_EM'));
9 LODOP.PREVIEW();
10 }
11 </script>
12 <object id="LODOP_OB" classid="clsid:2105C259-1E0C-4534-8141-A753534CB4CA" width=0 height=0>
13 <embed id="LODOP_EM" type="application/x-print-lodop" width=0 height=0 pluginspage="install_lodop.exe"></embed>
14 </object>
15 </head>
16 <body onload="init();">
17 </body>
18 </html>
