润乾报表V4技术资料

带参数模板的报表，封装打印方法时，要注意传参。

应用举例

1，如下封装，见下面的jsp代码：

<%@ page contentType=”text/html;charset=GBK” %>
<%@ taglib uri=”/WEB-INF/runqianReport4.tld” prefix=”report” %>
<report:param name=”form1″ paramFileName=”4.4_arg.raq” needSubmit=”yes” />
<report:html name=”report1″ reportFileName=”4.4.raq”
exceptionPage=”/reportJsp/myError2.jsp”
/>
<a href=”#” onclick=”report1_print();return false”>打印</a>
<script language=javascript>
function report1_print() {
document.report1_printIFrame.location = ” http://192.168.0.132:6001/demo/reportServlet?action=2&name=report1&reportFileName=4.4.raq&srcType=file&appletJarName=runqianReport4Applet.jar”;
}
</script>

打印的效果图：

2，如下封装，见下面的jsp代码：

<%@ page contentType=”text/html;charset=GBK” %>
<%@ taglib uri=”/WEB-INF/runqianReport4.tld” prefix=”report” %>
<%
request.setCharacterEncoding(”GBK”);
String paramsId = request.getParameter(”reportParamsId”);
%>
<report:param name=”form1″ paramFileName=”4.4_arg.raq” needSubmit=”yes” />
<report:html name=”report1″ reportFileName=”4.4.raq”
exceptionPage=”/reportJsp/myError2.jsp”
/>
<a href=”#” onclick=”report1_print();return false”>打印</a>
<script language=javascript>
function report1_print() {
document.report1_printIFrame.location = ” http://192.168.0.132:6001/demo/reportServlet?action=2&name=report1&reportFileName=4.4.raq&srcType=file&appletJarName=runqianReport4Applet.jar &reportParamsId=”+”<%=paramsId.toString()% >”;
}
</script>

打印的效果图：

1和2两个页面不同的地方是：

String paramsId = request.getParameter(”reportParamsId”);
reportParamsId=<%=paramsId.toString()%>

将这个reportParamsId传给了打印方法。
