本文实例讲述了JSP导出Excel文件的方法。分享给大家供大家参考,具体如下:
<%@page import=\"jxl.Workbook,com.ecc.emp.core.*,com.ecc.emp.data.*,com.ecc.emp.jdbc.ConnectionManager,jxl.format.VerticalAlignment,java.sql.*,jxl.write.*,jxl.format.UnderlineStyle,javax.sql.DataSource\"%> <%@page language=\"java\" contentType=\"text/html;

IndexedCollection indexedCollection = (IndexedCollection)context.getDataElement(\"parentCardDetails\"); String[] sourceStrArray=flag.split(\",\"); List selValList = new ArrayList(); selValList.add(\"序号#\"); for(int i=0;i<sourceStrArray.length;i++){ selValList.add(sourceStrArray[i]+\"#\"); } WritableWorkbook book = null; if (indexedCollection == null || indexedCollection.size()<0) {%> <script language=\"javascript\"> alert(\'对不起!当前条件没有数据,不能导出!\');
