js实现动态操作table

本章案例为通过js，动态操作table，实现在单页面进行增删改查的操作。
　　简要案例如下：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%> 
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
 <%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%> 
<%@ taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%> 
<%@page import="java.util.Date"%> 
<c:set var="ctx" value="${pageContext.request.contextPath}" /> 
<!DOCTYPE html> 
<html> 
<head> 
<script type="text/javascript"> function addOrder() { document.getElementById('hiddtr').style.display="table-row"; window.location="#hiddtr"; } function cancel(){ document.getElementById('hiddtr').style.display="none"; } function modify(ele){ var tr = $(ele).closest("tr"); var name = tr.find("input[name='name']"); var age = tr.find("input[name='age']"); if(name.val()==""){ alert("姓名不能为空"); return ; } if(age.val()==""){ alert("年龄不能为空"); return ; } if(!confirm("确认修改？")){ return; } $.ajax({ type: "POST", url: "${ctx}/user/update", dataType:"json", data: {name : name.val(),age:age.val()}, success: function(json){ if(json.msg=='success'){ alert("修改成功！"); }else{ alert(json.msg) } $(ele).attr("disabled",false); } }); } function deleteObj(ele,id){ if(confirm("确定要删除吗？")){ var url="${ctx}/user/delete/"+id; $.ajax({ type: "POST", url: url, dataType:"json", success: function(json){ if(json.msg=='success'){ alert("删除成功！"); $(ele).closest("tr").remove(); }else{ alert(json.msg) } $(ele).attr("disabled",false); } }); } } function classSubmit(ele){ var tr= $(ele).closest("tr"); var name = tr.find("input[name='name']"); var age = tr.find("input[name='age']"); if(name.val()==""){ alert("姓名不能为空"); return ; } if(age.val()==""){ alert("年龄不能为空"); return ; } $("#addForm").submit(); } </script> </head> <body> <button type="button" id="addOrder" onclick="addOrder()" >添加</button> <table id="table"> <thead> <tr> <th>id</th> <th>name</th> <th>age</th> <th></th> </tr> </thead> <tbody> <tr> <td>${(page.currPage-1) *page.pageSize+status.count}<input type="hidden" name="edId" value="${obj.id}"/></td> <td><input type="text" name="eqSn" value="${obj.name}"/></td> <td><input type="text" name="depPath" value="${obj.age}"/></td> <td><span onclick="deleteObj(this,'${obj.id}');">删除</span><span onclick="modify(this);">修改</span></td> </tr> <c:forEach var="obj" items="${list}" varStatus="status"> <tr> <td>${(page.currPage-1) *page.pageSize+status.count}<input type="hidden" name="edId" value="${obj.id}"/></td> <td><input type="text" name="eqSn" value="${obj.name}"/></td> <td><input type="text" name="depPath" value="${obj.age}"/></td> <td><span onclick="deleteObj(this,'${obj.id}');">删除</span><span onclick="modify(this);">修改</span></td> </tr> </c:forEach> <form action="${ctx}/user/add" method="post" id="addForm"> <tr style="display: none;" id="hiddtr"> <td></td> <td><input type="text" value="" name="name"/></td> <td><input type="text" value="" name="age" ></td> <td><input type="button" value="提交" onclick="classSubmit(this);return false;">

<input type="button" value="取消" onclick="cancel()"></td> </tr> </form> </tbody> </table> </body> </html>
