早上,我已经解决了一段时间了,无法弄清楚我对这段代码有什么疑问。目的是拥有一个网格(DataTable)并允许对该数据进行在线编辑(Editor)。我有从一个ajax调用获取数据的数据表,而编辑器正在使用另一个来更新记录。初始ajax很好并且可以正确填充,但是当我启动更新时,我发送的参数为null。这是一些代码:
<div>
<table id="post-table" class="table table-striped" style="width:100%">
<thead>
<tr role="row">
<th>postID</th><th></th><th></th><th></th><th></th>
</tr>
</thead>
<tbody></tbody>
</table>
</div>
<script src="~/Content/DataTables-1.10.18/js/jquery.dataTables.js"></script>
<script src="~/Content/editor-1.9.0/js/dataTables.editor.js"></script>
<link rel="stylesheet" type="text/css" href="~/Content/DataTables-1.10.18/css/jquery.dataTables.css">
<script language="javascript" type="text/javascript">
var editor;
editor = new $.fn.dataTable.Editor(
{
ajax: {
edit: {
type: "POST",
url: "/ActivationCampaign/UpdatePostRecord",
dataType: "json",
contentType: "application/json",
data: function (data) {
var obj = data.data;
var key = Object.keys(obj)[0];
var theJson = {};
theJson["campaignVersionID"] = @ViewBag.CampaignID;
theJson["salesChannelID"] = @ViewBag.SalesChannel;
theJson["postID"] = key;
theJson['amount'] = obj[key].amount;
return JSON.stringify(theJson);
}
}
},
table: "#post-table",
idSrc: "postID",
fields: [{
label: "",
name: "amount"
}]
}),
$(document).ready(function () {
$('#post-table').DataTable({
"ajax": {
"url": "/ActivationCampaign/LowLevelBudgetsForChannel?campaignID=@ViewBag.CampaignID&SalesChannelID=@ViewBag.SalesChannel",
"type": "GET",
"datatype": "json",
"dataSrc": ''
},
"pagingType": "simple",
"columnDefs": [
{"targets": [0], "visible": false, "searchable": false, "title": "post-id"},
{"targets": [1], "title": "Post" },
{"targets": [2], "title": "Post Number"},
{"targets": [3], "title": "Allocated Amount", "className": "allocated-column editable"},
{"targets": [4], "title": "Consumed Amount"}
],
"columns": [
{ "data": "postID" },
{ "data": "postName"},
{ "data": "postNumber" },
{ "data": "amount" },
{ "data": "formatedAmount" },
],
"initComplete": function (settings, json)
{
populateConsumed();
}
});
},
$('#post-table').on('click', 'tbody td:not(:first-child)', function (e)
{
editor.inline(this);
}));//end of doc ready
function populateConsumed()
{
var totalAmount = 0;
$(".allocated-column").each(function () {
var values = $(this).text().replace(',', '');
if (values > 0)
{
totalAmount += parseFloat(values);
}
});
$('#txtchangeBudget').val(JSON.stringify(totalAmount).replace(/\B(?=(\d{3})+(?!\d))/g, ","));
}
</script>
</div>
动作:
[System.Web.Mvc.HttpGet]
public JsonResult LowLevelBudgetsForChannel(int campaignID, int salesChannelID)
{//TODO get defensive on the parameters
return Json(activationCampaignService.GetLowLevelBudgetsForChannel(
campaignID, salesChannelID),
JsonRequestBehavior.AllowGet
);
}
[System.Web.Http.HttpPost]
public JsonResult UpdatePostRecord([FromBody]string budgetRecord)
{
if(budgetRecord == null)
{
}
return Json("hello");
//return Json(activationCampaignService.UpdatePostRecord(budgetRecord));
}
LowLevelBudgetsForChannel
调用工作正常,但UpdatePostRecord
中的budgetRecord
始终为空值。请注意,HttpPost属性来自与另一个不同的包,但是我只是更改了一个包,但是我担心现在同时安装了System.Net.Http
和System.Web.Http
,有人知道会出现什么问题吗?原因。
由于我需要构造要发送的json,并且要发送的数据代表多个表中的数据,因此我希望发送字符串并在操作中对其进行处理。居然IE调试器显示它认为我正在发送此消息:
{"campaignVersionID":186,"salesChannelID":45,"postID":"20","amount":"1001"}
我已经进入了旧系统,这有很多错误,但是我不认为这与它有任何关系,而且我只是没有正确设置。我最初没有正确设置内容类型或数据类型或from body属性,但是遵循该建议并不能解决我的问题。有什么建议吗?
[编辑] Iam当前认为,这与发生序列化有关,因为我在上面安装了Fiddler,并且值已在请求正文中发送。
答案 0 :(得分:0)
最后,我只需要创建与我发送的javascript结构匹配的类型,然后就可以正确填充所有内容。因此,可能是某种底层的序列化错误。有人有理由为什么字符串不能这样绑定吗?
