后台commit接收类：

Java版本处理

//设置请求编码
req.setCharacterEncoding("UTF-8");
//获取编辑数据 这里获取到的是json字符串
String deleted = req.getParameter("deleted");
String inserted = req.getParameter("inserted");
String updated = req.getParameter("updated");

if(deleted != null){
    //把json字符串转换成对象
    List<Bean> listDeleted = JSON.parseArray(deleted, Bean.class);
    //TODO 下面就可以根据转换后的对象进行相应的操作了
}

if(inserted != null){
    //把json字符串转换成对象
    List<Bean> listInserted = JSON.parseArray(inserted, Bean.class);
}

if(updated != null){
    //把json字符串转换成对象
    List<Bean> listUpdated = JSON.parseArray(updated, Bean.class);
}

Bean.java

public class Bean {
    private String code;
    private String name;
    private Double price;
    public String getCode() {
        return code;
    }
    public void setCode(String code) {
        this.code = code;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Double getPrice() {
        return price;
    }
    public void setPrice(Double price) {
        this.price = price;
    }
}

PHP版本处理：

<?php

if(isset($_POST["deleted"])){
    $deleted = $_POST["deleted"];//这里获取到的是一个json数组样子字符串，eg：[{code:'1',name:'name',price:323},{..},....]
    $listDeleted = json_decode($deleted); //把这个json数组转化成array对象
}

if(isset($_POST["inserted"])){
    $inserted = $_POST["inserted"];
    $listInserted = json_decode($inserted);
}

if(isset($_POST["updated"])){
    $updated = $_POST["updated"];
    $listUpdated = json_decode($updated);
}

ASP.NET MVC3版本：

//获取编辑数据 这里获取到的是json字符串
string deleted = Request.Form["deleted"];
string inserted = Request.Form["inserted"];
string updated = Request.Form["updated"];

if(deleted != null){
    //把json字符串转换成对象
    List<Bean> listDeleted = JsonDeserialize<List<Bean>>(deleted);
    //TODO 下面就可以根据转换后的对象进行相应的操作了
}

if(inserted != null){
    //把json字符串转换成对象
    List<Bean> listInserted = JsonDeserialize<List<Bean>>(inserted);
}

if(updated != null){
    //把json字符串转换成对象
    List<Bean> listUpdated = JsonDeserialize<List<Bean>>(updated);
}

JsonDeserialize方法：

private T JsonDeserialize<T>(string jsonString)
{
   DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(T));
   MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));
   T obj = (T)ser.ReadObject(ms);
   return obj;
}

里面用到的JSON.stringify，主要是把对象转换为字符串的作用。原代码在这里

注意下载这个js后，如果运行出错就去掉最后几行代码。如下删除

if (!Object.prototype.toJSONString) {
       Object.prototype.toJSONString = function (filter) {
           return JSON.stringify(this, filter);
       };
       Object.prototype.parseJSON = function (filter) {
           return JSON.parse(this, filter);
       };
   }
