基于.NET Core 3.1 网站开发和部署的方法

@model List<News> <div> <div> <partial /> </div> <div> <div>您现在所在的位置:中式餐厅酒店&gt;新闻动态</div> <div> @foreach (News item in @Model) { <div> <div><a href="NewsDetail?id=@item.Id" >@item.NewsTitle</a></div> <div>@item.PublishTime.ToShortDateString()</div> </div> } </div> </div> </div>

10.使用Section布局定义

@RenderSection("js",required:false)

使用

@section js{ <script type="text/javascript"> function changeFontSize(fontSize) { //获取要变化的对象 var divContent = $(".row .m-4"); divContent.css("font-size",fontSize); } </script> }

11.表单验证

使用模型验证方式实现

添加验证特性

public partial class DishBook { public uint Id { get; set; } public string HotelName { get; set; } [Required(ErrorMessage = "{0}不能为空")] [Display(Name = "消费时间")] public DateTime? ConsumeTime { get; set; } [Required(ErrorMessage = "{0}不能为空")] [RegularExpression(@"^d+$", ErrorMessage = "请输入正确的{0}")] [Display(Name = "消费人数")] public uint? ConsumePersons { get; set; } public string RoomType { get; set; } [Required(ErrorMessage = "{0}不能为空")] [RegularExpression(@"^(13[0-9]|14[5|7]|15[0|1|2|3|5|6|7|8|9]|18[0|1|2|3|5|6|7|8|9])d{8}$", ErrorMessage = "请输入正确的{0}")] [Display(Name = "手机号码")] public string CustomerPhone { get; set; } [Required(ErrorMessage = "{0}不能为空")] [Display(Name = "姓名")] public string CustomerName { get; set; } [EmailAddress(ErrorMessage = "请输入正确的{0}")] [Display(Name = "电子邮件")] public string CustomerEmail { get; set; } public string Comments { get; set; } public DateTime BookTime { get; set; } public int? BookStatus { get; set; } // 扩展属性 [Required(ErrorMessage = "{0}不能为空")] [Remote(action:"CheckVcode",controller:"Dish")] [Display(Name = "验证码")] public string ValidationCode { get; set; } }

使用 Tag Helper 完成前端代码编写
