我正在研究一种工具,这样我就可以在游戏中保持井井有条。
这是我的班级:
//The item
public class Item
{
public int Id { get; set; }
public string Name { get; set; }
public decimal Value { get; set; }
public ItemLabel Label { get; set; }
public ItemType Type { get; set; }
public ItemTradeType TradeType { get; set; }
public Trade Trade { get; set; }
}
Label / Type / TradeType / Trade
是枚举。
查看:
@model EveMonitorV2.Models.Item
@{
ViewBag.Title = "AddItem";
}
<h2>AddItem</h2>
@using (Html.BeginForm())
{
@Html.AntiForgeryToken()
@Html.ValidationSummary(true)
<fieldset>
<legend>Item</legend>
<div class="editor-label">
@Html.LabelFor(model => model.Name)
</div>
<div class="editor-field">
@Html.EditorFor(model => model.Name)
@Html.ValidationMessageFor(model => model.Name)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Value)
</div>
//What should be done here?
<div class="editor-field">
@Html.EditorFor(model => model.Value)
@Html.ValidationMessageFor(model => model.Value)
</div>
<div class="editor-label">
@Html.LabelFor(model => model.Trade)
</div>
<div class="editor-field">
@Html.CheckBoxFor()
@Html.ValidationMessageFor(model => model.Trade)
</div>
<p>
<input type="submit" value="Create" />
</p>
</fieldset>
}
<div>
@Html.ActionLink("Back to List", "Index")
</div>
enum有一整套可能性,我想制作一个Item Create视图
我遇到的问题:
我希望能够从枚举中选择更多选项。 (Like this) 类别是我的枚举。
这在asp.net mvc 4中是否可行?
(小记录:我还是学生,但这不是学校项目)
答案 0 :(得分:8)
创建View \ Shared \ EditorTemplates \ Options.cshtml
@using System.ComponentModel.DataAnnotations
@using System.Reflection
@model Enum
@{
var name = ViewData.TemplateInfo.HtmlFieldPrefix;
var type = Model.GetType();
}
@foreach (Enum e in Enum.GetValues(type))
{
var display = type.GetField(e.ToString()).GetCustomAttribute<DisplayAttribute>();
if (display != null && (display.GetAutoGenerateField() ?? true))
{
<label class="checkbox" title="@display.GetDescription()">
<input type="checkbox" name="@name" value="@e.ToString()" checked="@Model.HasFlag(e)" />
@display.Name
</label>
}
}
你的枚举可能被描述为下一个:
[Flags]
public enum MyOptions
{
[Display(AutoGenerateField = false)]
None = 0,
[Display(Name = "Option 1 name")]
Opt1 = 1 << 1,
[Display(Name = "Option 2 name")]
Opt2 = 1 << 2,
[Display(Name = "Option 3 name")]
Opt3 = 1 << 3,
}
,使用:
<div class="editor-field">
@Html.LabelFor(m => m.Trade)
@Html.EditorFor(m => m.Trade, "Options")
</div>
