接着上一篇博客,这次来完成多条数据的提交,我采用的是for循环,从session中获取到市直单位的id，从界面获取到提交指标的年份,指标类型,还有多条指标名称采用for循环的方式依次将他们放到数组中,因为我的数据要采用json格式,为了符合json的要求我需要将其放到对象中,然后使用stringify()方法,将其解析为字符串的形式传到一般处理程序中,接下来只要对解析出的数据依次写入数据库就O了，下面是具体的操作

  界面还是上一篇博客中看到的

js部分

function saveTarget() {
            document.getElementById("test").value = "save";
            //设定表示为后台调不同方法数据提供接口
            //document.getElementById("test").value = "add";
            //1.将id=txtName的value值存放到（UnitQuantifyTarget表）中的名称字段
            var txtNode = document.getElementsByName("txtName");
            //找到所有指标名称的个数
            var txtcount = parseInt($("input[name = ‘txtName‘]").length);
            //2.将id=targetstyle的value值存放到（UnitQuantifyTarget表）中的；类别字段
            var styleNode = document.getElementById("targetstyle");
            var checkValue = styleNode.options[styleNode.selectedIndex].text;
            //3.从服务器获取当前的年份，将其存放到（UnitQuantifyTarget表）中的年份字段
            var yearNode = document.getElementById("year");
            var yearValue = yearNode.options[yearNode.selectedIndex].text;           

            //用于向一般处理程序传值
            var test = document.getElementById("test").value;
            //实例化一个对象 ，用于存放test值
            var data1 = new Object();
            data1.test = test;
            //实例化一个数组用于存放从前台获取的值对象
            var array = new Array();
            //for循环，用于将多条数据同时传入到数组中，以便传到一般处理程序
            for (i = 0; i < parseInt($(txtNode).length) ; i++) {
                var obj = new Object();
                obj.txtname = txtNode[i].value;
                //如果指标名称不为空的话就将其加入到数组中
                if (obj.txtname != null && obj.txtname != "") {
                    obj.stylenode = checkValue;//指标类型
                    obj.year = yearValue;//时间
                    obj.ifrecord = "未录入";//录入状态
                    obj.unitId = "1";//市直单位id,应该是从session中获取,这里作为例子就直接拿一个数来代替了
                    array.push(obj);
                }
            }

            data1.array = array;
            //解析字符串
            var nid = JSON.stringify(data1);

            $.post("SubmitTargetJob.ashx", { action: "post", jsonArray: "" + nid + "" }, function (data) {
                if (data == "false") {
                    
                    alert("指标已存在,请核对信息重新添加！", "添加失败");

                } else {
                    alert("添加成功!", "提示");
                    window.location.reload();//重新加载页面
                }

            }, "text");

        }

一般处理程序

public void saveTarget(HttpContext context,JArray objget) {
            List<UnitQuantifyTargetEntity> list = new List<UnitQuantifyTargetEntity>();
            for (int i = 0; i < objget.Count; i++)
            {
                
                UnitQuantifyTargetEntity unitQuantifyTargetInfoEntity = new UnitQuantifyTargetEntity();
                JObject objectget = (JObject)objget[i];
                //解析从界面中传来的数据,注意[]中的内容一定要与界面传值时的名字一模一样。
                string txtname = objectget["txtname"].ToString().Trim();
                string stylenode = objectget["stylenode"].ToString().Trim();
                string yearValue = objectget["year"].ToString().Trim();
                string ifrecord = objectget["ifrecord"].ToString().Trim();
                string unitId = objectget["unitId"].ToString().Trim();

                //时间戳
                PublicBLL publicBll = new PublicBLL();
                string timestamp = publicBll.GetTime();

                //每循环一次将从界面获取的数据放到实体中以便D层使用
                unitQuantifyTargetInfoEntity.Name = txtname;
                unitQuantifyTargetInfoEntity.Type = stylenode;

                unitQuantifyTargetInfoEntity.other5 = null;
                //没循环一次将实体中的内容放到list中，循环结束后，所有的内容就都到list中啦，到时候用就好啦
                list.Add(unitQuantifyTargetInfoEntity);

            }
            if (unitQuantifyTargetBll.Add(list))//记得将list传过去
            {
                //调用B层的方法，如果成功了就将“true”返回到界面，界面会根据返回值继续后边的工作
                context.Response.Write("true");

        这三篇博客相当于我做的难点部分,做这个难点的主要原因是我们想让用户用着更方便,为了在任何位置都能添加一行,但是在实际项目中只考虑这一点是不够的,考虑多方便的因素我使用了easy_ui的datagrid控件中的Cell Editing in DataGrid控件,这个控件直接能编辑,并对选择的多条数据进行提交,挺方便的,随后我会把使用easy_ui控件做的上传到csdn,供大家参考.
