这里展示js合并table的单元格,代码亲测可行
后台采用springmvc搭建
Record实体类
public class Record { public String isp; public String large_area; public String province; public String name; public String age; ...... //省略get和set方法 }
action方法
@RequestMapping(value="/handlerList") public ModelAndView handlerList(HttpServletRequest request, HttpServletResponse response) throws Exception { List list = new ArrayList(); Record record1 = new Record(); record1.setIsp("CUC"); record1.setLarge_area("广东"); record1.setProvince("深圳"); record1.setName("name1"); record1.setAge("age1"); Record record2 = new Record(); record2.setIsp("CUC"); record2.setLarge_area("广东"); record2.setProvince("广州"); record2.setName("name2"); record2.setAge("age2"); Record record3 = new Record(); record3.setIsp("NU"); record3.setLarge_area("江西"); record3.setProvince("宜春"); record3.setName("name3"); record3.setAge("age3"); Record record4 = new Record(); record4.setIsp("NU"); record4.setLarge_area("江西"); record4.setProvince("宜春"); record4.setName("name4"); record4.setAge("age4"); Record record5 = new Record(); record5.setIsp("NU"); record5.setLarge_area("江西"); record5.setProvince("赣州"); record5.setName("name5"); record5.setAge("age5"); Record record6 = new Record(); record6.setIsp("NU"); record6.setLarge_area("湖南"); record6.setProvince("郴州"); record6.setName("name6"); record6.setAge("age6"); list.add(record1); list.add(record2); list.add(record3); list.add(record4); list.add(record5); list.add(record6); Map map = new HashMap(); map.put("list", list); return new ModelAndView("/showList",map); }
jsp页面展示
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> <%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Insert title here</title> <script type="text/javascript"src="asserts/js/jquery-1.7.2.min.js"></script> </head> <body> <table id="testTable" width="100%" border="1"> <thead> <tr align="center"> <th width="94" height="38">运营商</th> <th width="198" height="38" >7天平均冗余带宽(G)</th> <th width="216" height="38" >今天冗余带宽(G)</th> <th width="196" height="38" >未来30天冗余带宽(G)</th> <th width="263" height="38" >目前已用带宽(G)</th> </tr> </thead> <thbody> <c:forEach var="item" items="${list}" varStatus="status"> <tr> <td>${item.isp }</td> <td>${item.large_area}</td> <td>${item.province}</td> <td>${item.name}</td> <td>${item.age}</td> </tr> </c:forEach> </thbody> </table> </body> </html>
可以看到未合并时效果如下:
jsp页面中添加相关的js片段后
<SCRIPT type="text/javascript"> $(document).ready(function () { table_rowspan("#testTable", 1); table_rowspan("#testTable", 2); table_rowspan("#testTable", 3); }) //函数说明:合并指定表格(表格id为table_id)指定列(列数为table_colnum)的相同文本的相邻单元格 //参数说明:table_id 为需要进行合并单元格的表格的id。如在HTMl中指定表格 id="table1" ,此参数应为 #table1 //参数说明:table_colnum 为需要合并单元格的所在列。为数字,从最左边第一列为1开始算起。 function table_rowspan(table_id, table_colnum) { table_firsttd = ""; table_currenttd = ""; table_SpanNum = 0; colnum_Obj = $(table_id + " tr td:nth-child(" + table_colnum + ")"); colnum_Obj.each(function (i) { if (i == 0) { table_firsttd = $(this); table_SpanNum = 1; } else { table_currenttd = $(this); if (table_firsttd.text() == table_currenttd.text()) { table_SpanNum++; table_currenttd.hide(); //remove(); table_firsttd.attr("rowSpan", table_SpanNum); } else { table_firsttd = $(this); table_SpanNum = 1; } } }); } //函数说明:合并指定表格(表格id为table_id)指定行(行数为table_rownum)的相同文本的相邻单元格 //参数说明:table_id 为需要进行合并单元格的表格id。如在HTMl中指定表格 id="table1" ,此参数应为 #table1 //参数说明:table_rownum 为需要合并单元格的所在行。其参数形式请参考jQuery中nth-child的参数。 // 如果为数字,则从最左边第一行为1开始算起。 // "even" 表示偶数行 // "odd" 表示奇数行 // "3n+1" 表示的行数为1、4、7、10....... //参数说明:table_maxcolnum 为指定行中单元格对应的最大列数,列数大于这个数值的单元格将不进行比较合并。 // 此参数可以为空,为空则指定行的所有单元格要进行比较合并。 function table_colspan(table_id, table_rownum, table_maxcolnum) { if (table_maxcolnum == void 0) { table_maxcolnum = 0; } table_firsttd = ""; table_currenttd = ""; table_SpanNum = 0; $(table_id + " tr:nth-child(" + table_rownum + ")").each(function (i) { row_Obj = $(this).children(); row_Obj.each(function (i) { if (i == 0) { table_firsttd = $(this); table_SpanNum = 1; } else if ((table_maxcolnum > 0) && (i > table_maxcolnum)) { return ""; } else { table_currenttd = $(this); if (table_firsttd.text() == table_currenttd.text()) { table_SpanNum++; table_currenttd.hide(); //remove(); table_firsttd.attr("colSpan", table_SpanNum); } else { table_firsttd = $(this); table_SpanNum = 1; } } }); }); } </SCRIPT>
效果如下,可以看到字段相同的列已经进行合并了:
