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>
