Layui treeTable 使用【数据不显示、子级不显示】
//返回JSON数据类 public class LeaveMessageTreeTable { public LeaveMessageTreeTable() { this.children = new List<LeaveMessageTreeTable>(); this.isParent = false; } public int Id { get; set; } public int UserId { get; set; } public int BeUserId { get; set; } public string name { get; set; } public string? UserIp { get; set; } public string? UserAddress { get; set; } public string Content { get; set; } public int Status { get; set; } public DateTime CreateTime { get; set; } public bool isParent { get; set; } public int? parentId { get; set; } public List<LeaveMessageTreeTable> children { get; set; } }
!!!一直不显示子级或者数据出不来一定要注意这4个字段,字段名一定要一模一样 ,包括大小写!!!
数据中标红线的都是必填的,且字段名要一模一样,大小写也要一致
children:表示子级数据,数据格式跟父级一致
isParent:是否有父级:有就位true,否则为false,因此第一级一定是false
name:就是图中的用户名,点击下一级的地方,这个名字是固定的,必须要有
parentId:跟子级关联的父级Id,没有父级则为null
页面JS
