我是MVC的新手。我有一个使用ASP.NET使用MVC5框架的项目。我有一个名为addContract的视图，它包含两个dropdownList，一个是服务提供者，第二个是服务提供者。我还有一个两个datepickers开始和结束日期，一个合同数量的文本框，最后一个包含文章列表的表，我将在合同和价格中选择我想要的文章。每件事都有利于我已经实现了一个函数，它将添加所选复选框的值和价格的文本框的值，并将它们合并到一个数组中，并通过ajax和jquery发送给控制器。问题是，当我去控制器时，我在数组的变量中得到了Null。但服务和日期的所有其他值都很好。
请帮帮我，最好的办法是什么!!!
这是我的视图代码，只是我发现问题的表的代码：
<table class="table table-bordered table-striped table-hover" id="tab">
<thead>
<tr>
<td>Choose</td>
<td>Reference</td>
<td>Article Name</td>
<td>Price</td>
</tr>
</thead>
<tbody>
@foreach (var ar in Model)
{
<tr>
<td><input type="checkbox" name="CheckboxGroup1" value="@ar.reference" ID="chk" class="check"></td>
<td>@ar.reference</td>
<td>@ar.Name</td>
<td> <input type="text" id="txt" name="@ar.reference" placeholder="TND" ></td>
</tr>
}
</tbody>
</table>
this is the jquery script :
//***testing if a checkbox is selected and add the selected row in an array***//
//the table that will store selected items
var Num_Contrat = "";
var Date_Deb = "";
var Date_Fin = "";
var Price = "";
var Service_Provider_List = "";
var Service_List = "";
var selected = [];
//**(1) -im gonna find the table body and checkbox
$('table#tab tbody').on('change', '.check', function () {
var ischecked = $(this).is(":checked");
if (ischecked) {
selected.push($(this).val() + "," + $(this).closest('tr').find("#txt").val());
} else {
if ((index = selected.indexOf($(this).val() + "," + $(this).closest('tr').find("#txt").val())) !== -1) {
selected.splice(index, 1);
}
}
// (4) -and finnally i m gonna Remove duplicate elements from selected array
selected = $.unique(selected);
alert(selected);
});
//Validation
