我这段脚本语言在另外的一个jsp文件打印就行 但是在用了EXT的jsp页面  IE运行老是提示脚本语言有错    

<script language=javascript>function printpr()   //预览函数

{

var OLECMDID = 7;

var PROMPT = 1;

 var WebBrowser = '<OBJECT ID="WebBrowser1" WIDTH=0 HEIGHT=0 CLASSID="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2"></OBJECT>';

document.body.insertAdjacentHTML('beforeEnd', WebBrowser);//在body标签内加入html（WebBrowser activeX控件）

 WebBrowser1.ExecWB(OLECMDID, PROMPT);WebBrowser1.outerHTML = "";} 

</script>
