JQuery EasyUI类库，大家不会陌生，出来已经有很多年了。个人感觉还是很好用的，作者更新频率也很快，bug也及时修复。
最近在整理以前的代码，找到了这个组件，它是将EasyUI组件封装成MVC控件，这样我们就可以不用写那些html标签了，我们先看看调用方式
<form id="form1">
@Html.HiddenFor(c => c.ID)
@Html.HiddenFor(c => c.EditMode)
@Html.HiddenFor(c => c.CodeTypeID)
@Html.HiddenFor(c => c.CreateUserID)
<table border="1" style="width: 100%;">
<tr>
<td style="width: 100px;">@Html.EasyUI().LabelFor(c => c.CodeID).Required(true)</td>
<td>@Html.EasyUI().ValidateBoxFor(c => c.CodeID).Required(true).Width("60%")</td>
</tr>
<tr>
<td>@Html.EasyUI().LabelFor(c => c.CodeName).Required(true)</td>
<td>@Html.EasyUI().ValidateBoxFor(c => c.CodeName).Required(true).Width("60%")</td>
</tr>
<tr>
<td>@Html.EasyUI().LabelFor(c => c.CodeTypeName)</td>
<td>@Html.DisplayFor(c => c.CodeTypeName)</td>
</tr>
<tr>
<td>@Html.EasyUI().LabelFor(c => c.IsUsed)</td>
<td>@Html.DropDownListMetaCodeFor(c => c.IsUsed, MetaSourceType.Null, string.Empty, new{ @style = "width:60%;" })</td>
</tr>
<tr>
<td>@Html.EasyUI().LabelFor(c => c.SortOrder)</td>
<td>@Html.EasyUI().NumberBoxFor(c => c.SortOrder).Min(10).Value(10).Width("60%")</td>
</tr>
<tr>
<td>@Html.EasyUI().LabelFor(c => c.CreateUserName)</td>
<td>@Html.EasyUI().ValidateBoxFor(c => c.CreateUserName).Width("60%")</td>
</tr>
<tr>
<td>@Html.EasyUI().LabelFor(c => c.CreateTime)</td>
<td>@Html.EasyUI().DateBoxFor(c => c.CreateTime)</td>
</tr>
</table>
</form>
我们再来看看代码是如何实现的，下面是整个项目布局
其实代码不复杂，最关键的是TagElementBuilder.cs这个类

}
#endregion

private bool ContainsClass(string className)
{
string classs;
if (!TagBuilder.Attributes.TryGetValue("class", out classs))
{
return false;
}
var classArray = classs.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries).ToArray();
return classArray.Any(i => string.Equals(i, className, StringComparison.OrdinalIgnoreCase));
}

}
var classs = TagBuilder.Attributes["class"];
var classArray = classs.Split(new[] { ' ' }, StringSplitOptions.RemoveEmptyEntries)

TagBuilder.Attributes["class"] = string.Join(" ", classArray);
return this as T;
}
