MVC使用jQuery从视图向控制器传递Model,数据验证,MVC HTML辅助方法小结

//MVC HTML辅助类常用方法记录

（1）@Html.DisplayNameFor(model => model.Title)是显示列名，

（2）@Html.DisplayFor(modelItem => item.Title)是显示列的内容

（3）@Html.ActionLink("Create New", "Create")是超链接，跳转到model中的create页面，引用的是controller中create方法；

（4）@Html.ActionLink("Edit", "Edit", new { id=item.ID })编辑页面；

（5）@using (Html.BeginForm()) {   @Html.ValidationSummary(true)}用于客户端验证，其Html.BeginForm()表示在本页显示

（6）<div class="editor-label">
		@Html.LabelFor(model => model.Time)标签
	</div>
	<div class="editor-field">
		@Html.EditorFor(model => model.Time)编辑框
		@Html.ValidationMessageFor(model => model.Time)验证合法性错误显示
	</div>
