需求：
2016年12月2号，今天碰到一个问题就是如何选中jsp页面的多条数据，进行批量处理。
效果：
实现思路：
jsp页面
<%@ page contentType="text/html; charset=GBK" pageEncoding="GBK"%> <%@ taglib uri="/WEB-INF/cvicse-common.tld" prefix="common"%> <%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html"%> <%@ taglib uri="/WEB-INF/struts-logic.tld" prefix="logic"%> <%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean"%> <%@ taglib uri="/WEB-INF/cvicse-param.tld" prefix="param"%> <%@ page import="com.cvicse.jr.lbms.la.bo.RentManagementQueryObject" %> <%@ page import="com.cvicse.jr.lbms.la.bo.Project" %> <%@page import="com.cvicse.jr.lbms.cs.util.RentPlanUtil"%> <% response.setHeader("Pragma", "no-cache");

var num1 = num[4].replace(/,/g,"");//利息 var num2 = num[6].replace(/,/g,"");//租金 var num3 = num[7].replace(/,/g,"");//本金 result1=parseFloat(result1)+parseFloat(num1); result2=parseFloat(result2)+parseFloat(num2);

batchPay(); } function toBack(){ //window.location.href="supplierRentManagementAction.do?operAtt=query"; //window.location.href="javascript:history.go(-2)"; with (document.forms[0]) { operAtt.value="query";

//获得页面上还款账户名称 String[] collectAccount = form.getCollectAccount1(); //获得页面上还款银行名称 String[] collectBank = form.getCollectBank1(); //或的页面实际还款时间 Date[] realDate = form.getRealDate(); //业务编号数组 String[] ywbh = new String[checkProjectId.length]; //realId编号数组 String[] realid = new String[checkProjectId.length]; //项目编号数组 String[] prjno = new String[checkProjectId.length]; //期次数组 Map map = new HashMap(); int[] retnum = new int[checkProjectId.length]; //次数 int i=0; //改变获得时间的的格式 SimpleDateFormat ds = new SimpleDateFormat("yyyy-MM-dd"); String a = ds.format(realDate[0]); for(int k=0;k<checkProjectId.length;k++){ String[] part = checkProjectId[k].split("#"); }
