我有一个通过 jquery 生成的表单:

 $.get("/api/get/getListItems", function (data) {
                var table = "";
                table += "<table>";
                $.each(data, function (y, z) {
                    console.log(z);
                    table += '<tr>';
                    $.each(this, function (k, v) {
                        table += '<td><input type="text" name="' + k + '" id="' + k + '" value="' + v + '" /></td>';
                    });
                    table += '<td><input type="checkbox" name="selected" id="selected" /></td>';

                    table += '</tr>';
                });
                table += '<tr><td><input type="submit" id="submit" name="submit" value="Save To Database" /></td></tr>';
                table += '</table>';
                $('#form').html(table);
            });

它生成这个 HTML(10 行输入字段，7 列和 1 个复选框):http://jsfiddle.net/8zpr2fkL/1/

单击提交按钮时我正在提交表单:

$("#form").submit(function (event) {
        $.post("/api/update/", $("#form").serialize(), alert('success'));
    });

现在我将数据传递到我的 ASP.NET API Controller :

[HttpPost]
        public dynamic Post([FromBody]CellModel cells)
        {
                UpdateClass jobs = new UpdateClass();
                return jobs;
        }

这是我的 CellModel 类:

public class CellModel
    {
        public uint scheduleTaskID { get; set; }
        public string task { get; set; }
        public string baselineDate { get; set; }
        public string scheduledDate { get; set; }
        public string actualDate { get; set; }
        public string finishedDate { get; set; }
        public bool selected { get; set; }

        public override string ToString()
        {
            return scheduleTaskID.ToString();
        }
    }

我的问题是当我点击提交提交数据并在 Controller 方法上放置一个断点时，单元格计数为 0，我在这里遗漏了什么吗？我正在尝试将输入文本中的所有数据传递给 Controller ​​。什么都没有传递到我的 Controller 。我做错了什么？

这是我试图通过 jquery $('#form').serialize() 传递的数据:

scheduleTaskID=194&task=Permit&baselineDate=6%2F23%2F2005+8%3A00%3A00+AM&scheduledDate=6%2F23%2F2005+8%3A00%3A00+AM&actualDate=6%2F23%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=195&task=Office+Files&baselineDate=7%2F13%2F2005+8%3A00%3A00+AM&scheduledDate=7%2F13%2F2005+8%3A00%3A00+AM&actualDate=7%2F13%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=196&task=Foundation&baselineDate=7%2F27%2F2005+8%3A00%3A00+AM&scheduledDate=7%2F27%2F2005+8%3A00%3A00+AM&actualDate=8%2F13%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=197&task=Framing&baselineDate=8%2F5%2F2005+8%3A00%3A00+AM&scheduledDate=8%2F5%2F2005+8%3A00%3A00+AM&actualDate=8%2F23%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=198&task=Finishes+Exterior&baselineDate=8%2F26%2F2005+8%3A00%3A00+AM&scheduledDate=8%2F26%2F2005+8%3A00%3A00+AM&actualDate=9%2F14%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=199&task=Drywall&baselineDate=9%2F2%2F2005+8%3A00%3A00+AM&scheduledDate=9%2F2%2F2005+8%3A00%3A00+AM&actualDate=9%2F16%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=200&task=Flooring&baselineDate=9%2F1%2F2005+8%3A00%3A00+AM&scheduledDate=9%2F1%2F2005+8%3A00%3A00+AM&actualDate=9%2F20%2F2005+8%3A00%3A00+AM&finishedDate=&scheduleTaskID=201&task=General+Finish&baselineDate=9%2F12%2F2005+8%3A00%3A00+AM&scheduledDate=9%2F12%2F2005+8%3A00%3A00+AM&actualDate=&finishedDate=&scheduleTaskID=202&task=Final+PDI&baselineDate=10%2F11%2F2005+8%3A00%3A00+AM&scheduledDate=10%2F11%2F2005+8%3A00%3A00+AM&actualDate=&finishedDate=&scheduleTaskID=203&task=Permit&baselineDate=4%2F6%2F2005+8%3A00%3A00+AM&scheduledDate=4%2F6%2F2005+8%3A00%3A00+AM&actualDate=4%2F6%2F2005+8%3A00%3A00+AM&finishedDate=

更新

我已经改变了:

$("#form").submit(function (event) {
            $.post("/api/update/", $("#form").serialize(), alert('success'));
        });

到

$("#form").submit(function (event) {
        var array = [];
        $('#form > table > tbody  > tr').each(function (elem) {
            var item = {};
            item.scheduleTaskID = $(this).find("td > #scheduleTaskID").val();
            item.task = $(this).find("td > #task").val();
            item.baselineDate = $(this).find("td > #baselineDate").val();
            item.scheduledDate = $(this).find("td > #scheduledDate").val();
            item.actualDate = $(this).find("td > #actualDate").val();
            item.finishedDate = $(this).find("td > #finishedDate").val();
            item.selected = $(this).find("td > #selected").val();
            array.push(item);
        });
        console.log(JSON.stringify(array));
        $.post("/api/update/", JSON.stringify(array), alert('success'), 'json');
    });

在我的控制台日志中，我的数据如下所示:

[{"scheduleTaskID":"203","task":"Permit","baselineDate":"4/6/2005 8:00:00 AM","scheduledDate":"4/6/2005 8:00:00 AM","actualDate":"4/6/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"195","task":"Office Files","baselineDate":"7/13/2005 8:00:00 AM","scheduledDate":"7/13/2005 8:00:00 AM","actualDate":"7/13/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"196","task":"Foundation","baselineDate":"7/27/2005 8:00:00 AM","scheduledDate":"7/27/2005 8:00:00 AM","actualDate":"8/13/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"197","task":"Framing","baselineDate":"8/5/2005 8:00:00 AM","scheduledDate":"8/5/2005 8:00:00 AM","actualDate":"8/23/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"198","task":"Finishes Exterior","baselineDate":"8/26/2005 8:00:00 AM","scheduledDate":"8/26/2005 8:00:00 AM","actualDate":"9/14/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"199","task":"Drywall","baselineDate":"9/2/2005 8:00:00 AM","scheduledDate":"9/2/2005 8:00:00 AM","actualDate":"9/16/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"200","task":"Flooring","baselineDate":"9/1/2005 8:00:00 AM","scheduledDate":"9/1/2005 8:00:00 AM","actualDate":"9/20/2005 8:00:00 AM","finishedDate":"","selected":"on"},{"scheduleTaskID":"201","task":"General Finish","baselineDate":"9/12/2005 8:00:00 AM","scheduledDate":"9/12/2005 8:00:00 AM","actualDate":"","finishedDate":"","selected":"on"},{"scheduleTaskID":"202","task":"Final PDI","baselineDate":"10/11/2005 8:00:00 AM","scheduledDate":"10/11/2005 8:00:00 AM","actualDate":"","finishedDate":"","selected":"on"},{"scheduleTaskID":"203","task":"Permit","baselineDate":"4/6/2005 8:00:00 AM","scheduledDate":"4/6/2005 8:00:00 AM","actualDate":"4/6/2005 8:00:00 AM","finishedDate":"","selected":"on"},{}]

在我的 ASP.NET API Controller 中，我将我的方法更改为:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using MvcApplication1.Models;

namespace MvcApplication1.Controllers
{
    public class UpdateController : ApiController
    {
        [HttpPost]
        public dynamic Post(List<CellModel> cells)
        {
                UpdateClass jobs = new UpdateClass();
                //jobs.PostScheduledTasks(cells);
                return cells;
        }

    }
}

我在方法 Post 的开头放置了一个断点，当它遇到断点时，它说单元格计数 = 0..我看到网络调用，只有当我在我的 post 调用后返回 false 并且响应为空时[] 为什么数据没有传递到我的 Controller ，是因为表单是由 jquery 生成的吗？

更新

仍然没有解决方案，我查看了我的网络调用 AM，状态代码为 301:

最佳答案

不要使用 $.post 使用 ajax post 并将内容类型设置为 “应用程序/json；字符集=utf-8”

var data = JSON.stringify(array);
$.ajax({
  url:"/api/update/",
  type:"POST",
  data:data,
  contentType:"application/json; charset=utf-8",
  dataType:"json",
  success: function(data){
    console.log(data);
  }
});

问题是你需要告诉网络服务器你正在发送 json 而 $.post 是不可能的

这真的很正常，我也一直在纠结这个问题(有时我仍然忘记了)，这里你可以看到你必须使用 $.ajax
