批量打印

◆ 实例请参考网页脚本控制实例 / 批量直接打印

 

背景说明：

客户端经常需要对报表进行批量打印，此时可以调用applet打印、PDF打印或本地打印进行批量打印操作，用法如下：

applet打印：

<%

//report的参数格式为：report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}...prompt=yes

request.setCharacterEncoding( "GBK" );

String report = request.getParameter( "report" );

if( report == null || report.trim().length() == 0 ) throw new Exception( "请输入报表文件名及参数串report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}..." );

String prompt = request.getParameter( "prompt" );

String appmap = request.getContextPath();

String serverPort = String.valueOf( request.getServerPort() );

String serverName = request.getServerName();

String appRoot = "http://" + serverName + ":" + serverPort + appmap;

%>

function raqsoft_getPrintReports() {

//请在此函数里加上打印前需要的处理，最后返回需要打印的报表

return "<%=report%>";

}

</script>

 

PDF打印：

<script language=javascript>

var myToast;

function showToast() {

myToast = $().toastmessage('showToast', {

text : '<%=ServerMsg.getMessage(request,"jsp.loadingPrint")%>',

sticky: true,

position : 'middle-center',

type: 'notice'

});

}

function closeToast() {

$().toastmessage('removeToast', myToast);

}

</script>

……

<%

//report的参数格式为：report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}

request.setCharacterEncoding( "UTF-8" );

String report = request.getParameter( "report" );

if( report == null || report.trim().length() == 0 ) throw new Exception( "请输入报表文件名及参数串report={无参数报表名}{报表1(参数1=value1;参数2=value2;...)}{报表2(参数1=value1;参数2=value2;...)}..." );

String src = request.getContextPath() + ServletMappings.getMapping( "com.raqsoft.report.view.ReportServlet" ) + "?action=45&report=" + URLEncoder.encode( report, "UTF-8" );

String preview = request.getParameter( "preview" );

if( "no".equalsIgnoreCase( preview ) ) {

String url = appmap + ReportConfig.raqsoftDir + "/pdfjs/pdfDirectPrint.jsp?src=" + URLEncoder.encode( src, "UTF-8" );

%>

<iframe src="<%=url%>" style="position:absolute;left:-100px;top:-100px" width=50 height=50>

</iframe>

<script language=javascript>

showToast();

</script>

<%

}

else {%>

本地打印：
