我有一个视图,我有条件地迭代和打印项目:不显示SPAN(如预期的那样)。
<div>
@if (Model.SomeCondition)
{
@foreach (var x in Model.SomeData)
{
<span>@x.Title</span>
}
}
</div>
现在我不想显示封闭的DIV,但它不起作用:SPAN仍未显示,但DIV是。为什么会这样?
@if (Model.SomeCondition)
{
<div>
@foreach (var x in Model.SomeData)
{
<span>@x.Title</span>
}
</div>
}
这是完整的视图代码:
@using Team.L
@using Microsoft.AspNetCore.Mvc.Localization
@inject IViewLocalizer Localizer
@model Team.ViewModels.DeptTaskGroupView
@{
var EventHandler = "Aventin." + ViewBag.AspAction + "(event)";
}
<form asp-controller="ModulesEx" asp-action="@ViewBag.AspAction" onsubmit="return false">
<div class="form-horizontal">
<input type="hidden" asp-for="Errors">
<div class="MessageBox">@Html.Raw(Utility.GetMessage(Model))</div>
<div class="form-group col-md-offset-2">
<label class="col-md-2"></label>
<div class="col-md-10">
<span data-valmsg-for="" class="text-danger" />
</div>
</div>
<div class="form-group">
<label class="col-md-2 control-label">@MyText.Department</label>
<div class="col-md-10">
<select asp-for="DepartmentID" class="form-control" asp-items="@Model.DepartmentList" onchange="@EventHandler"></select>
<span asp-validation-for="DepartmentID" class="text-danger" />
</div>
</div>
@if (Model.AssignedTaskGroup != null)
{
<div class="form-group">
<label class="col-md-2 control-label">@MyText.TaskGroup</label>
<div class="col-md-10">
@foreach (var x in Model.AssignedTaskGroup)
{
<input type="checkbox" name="selectedItems" value="@x.ID" @(Html.Raw(x.Assigned ? "checked=\"checked\"" : "")) />
@x.Title
}
</div>
</div>
}
<div class="form-horizontal">
<div class="form-group">
<div class="col-md-1 col-md-offset-2">
<input type="submit" value="@MyText.Save" class="btn btn-default" />
</div>
</div>
</div>
</div>
</form>

如上所述,它不会发生。我猜你要么没有重新加载页面,要么你的演示代码周围有代码呈现这个div所包含的div。
