js弹出图片原图效果

1.将js方法独立出来common.js

function openwin(src){
       var basePath = document.getElementById("basePath").value;
       src = basePath + src;
       //alert(src);
       OpenWindow=window.open("","newwin",",toolbar=no,menubar=no,scrollbars=yes,resizable=yes,location=no,status=no");
       //写成一行
       OpenWindow.document.write("<TITLE>查看图片</TITLE>");
       OpenWindow.document.write("<BODY BGCOLOR=#ffffff>");
       //OpenWindow.document.write("<h1>Hello!</h1>");
       OpenWindow.document.write("<img src='"+src+"' />");
       OpenWindow.document.write("</BODY>");
       OpenWindow.document.write("</HTML>");
       OpenWindow.document.close();
   }

2.在需要调用的jsp嵌入

<%
String basePath = request.getScheme() + "://" + request.getServerName() +":"+ request.getServerPort() + request.getContextPath() + "/";
%>
<input type="hidden" value="<%=basePath%>" id="basePath" />
<script language="javascript" type="text/javascript" src="<%=basePath %>js/biz/common.js"></script>

<a href="javascript:void(0);" onclick="openwin('${mem.idCard}/');" title="点击查看原图"><img src="${mem.idCard}/" width="500" height="360"/></a>
