遵循一个简单的教程,我已经在我的jQuery Datatables中实现了AJAX,但是我不确定如何使用我在数据视图模型中创建的所有数据注释。我该怎么做呢?在使用Ajax之前,我的视图中会有如下内容(使用razor):
<tbody>
@foreach (CallableNoteViewModel vm in Model)
{
<tr>
<td>@Html.DisplayFor(modelItem => vm.UnderlyingAsset) </td>
<td>@Html.DisplayFor(modelItem => vm.PayoutCurrency)</td>
<td>@Html.DisplayFor(modelItem => vm.Term)</td>
<td>@Html.DisplayFor(modelItem => vm.AutoCallLevel)</td>
<td>@Html.DisplayFor(modelItem => vm.Frequency)</td>
<td>@Html.DisplayFor(modelItem => vm.Barrier)</td>
<td>@Html.DisplayFor(modelItem => vm.CouponBarrier)</td>
<td>@Html.DisplayFor(modelItem => vm.AutoCallableStart)</td>
<td>@Html.DisplayFor(modelItem => vm.UpsideParticipation)</td>
<td>@Html.DisplayFor(modelItem => vm.Fee)</td>
<td>@Html.DisplayFor(modelItem => vm.Coupon)</td>
<td>@Html.DisplayFor(modelItem => vm.AsOfDate)</td>
</tr>
}
</tbody>
现在,很自然地,我的观点是这样的,没有身体。:
<table id="ajax_ci_table" class="table table-striped table-bordered table-responsive" style="white-space: nowrap">
<thead>
<tr>
<th>@Html.DisplayNameFor(model => model.UnderlyingAsset)</th>
<th>@Html.DisplayNameFor(model => model.PayoutCurrency)</th>
<th>@Html.DisplayNameFor(model => model.Term)</th>
<th>@Html.DisplayNameFor(model => model.AutoCallLevel)</th>
<th>@Html.DisplayNameFor(model => model.Frequency)</th>
<th>@Html.DisplayNameFor(model => model.Barrier)</th>
<th>@Html.DisplayNameFor(model => model.CouponBarrier)</th>
<th>@Html.DisplayNameFor(model => model.AutoCallableStart)</th>
<th>@Html.DisplayNameFor(model => model.UpsideParticipation)</th>
<th>@Html.DisplayNameFor(model => model.Fee)</th>
<th>@Html.DisplayNameFor(model => model.Coupon)</th>
<th>@Html.DisplayNameFor(model => model.AsOfDate)</th>
</tr>
</thead>
<tbody>
</tbody>
这是由我的AjaxController填充的,它返回JSON数据:
IEnumerable<string[]> stringdata = from c in data
select new[]
{
c.UnderlyingAsset,
c.PayoutCurrency,
c.Term.ToString(),
c.AutoCallLevel.ToString(CultureInfo.InvariantCulture),
c.Frequency.ToString(),
c.Barrier.ToString(CultureInfo.InvariantCulture),
c.CouponBarrier.ToString(CultureInfo.InvariantCulture),
c.AutoCallableStart.ToString(),
c.UpsideParticipation.ToString(CultureInfo.InvariantCulture),
c.Fee.ToString(CultureInfo.InvariantCulture),
c.Coupon.ToString(CultureInfo.InvariantCulture),
c.AsOfDate.ToString(CultureInfo.InvariantCulture)
};
但是现在,我的数据注释显然不能用于我的视图模型的格式化。像这样的东西:
[Display(Name = "PayFreq")]
[UIHint("FrequencyAndTerm")]
public int Frequency
{
get { return _callableNote.Frequency; }
}
如何格式化数据或使用现有的数据注释,而不直接在控制器中返回格式化数据(在我的倒数第二个代码块中)?我觉得在控制器中返回格式化数据是错误的。这不是视图的工作吗?
谢谢你的帮忙!

CoolboyJules,
我不认为DisplayFor使用注解。尝试使用编辑器类型的帮助器而不是显示。
@Html.TextboxFor(m => m.UnderlyingAsset);
不确定您的整个视图是什么样子,但这里有一个快速模板。该模型具有布尔型IsViewOnly标志
@using (Ajax.BeginForm("Edit", "Inventory", null, ajaxOptions, new { id = "frmInventoryEditModal" }))
{
<!-- modal div -->
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h2 style="color: darkorchid Title</h2>
</div>
<div id="ErrorSummary">
@Html.ValidationSummary(true)
</div>
<div class="modal-body" id="modal-body">
<div class="row-fluid DataRow">
@using (Html.ControlGroupFor(m => m.UnderlyingAsset))
{
@Html.LabelFor(m => m.UnderlyingAsset, new { @class = "control-label" })
<div class="controls">
@Html.TextBoxFor(m => m.UnderlyingAsset)
</div>
}
</div>
// Continue for the rest of the fields in model
</div>
<div class="modal-footer">
@if (!Model.IsViewOnly)
{
<button id="btnSave" type="button" class="btn btn-primary">Save changes</button>
}
<button id="btnCancel" class="btn btn-success" data-dismiss="modal" aria-hidden="true">Cancel</button>
</div>
}
这些帮助器查找适当的html并将其添加到呈现的控件中,该控件应显示您的属性。
希望这能有所帮助。
