MVC4制作网站教程第四章 浏览栏目4.2

一、用户

二、用户组

三、栏目

3.1添加栏目

3.2浏览栏目

浏览栏目这块做个一个树形列表,添加栏目的左侧部分只写了句“左侧列表”就是指这个树形列表,等我们写完替换一下就可以了。

先在【CategoryController】里面添加[ManagePartialTree]action,这里的Partial用来说明是分部视图

/// 
    /// 栏目列表局部树视图
    /// 
    /// 
    [AdminAuthorize]
    public ActionResult ManagePartialTree()
    {
      return View();
    }

右键添加分部视图ManagePartialTree.cshtml。分部视图里用easyui的tree来显示栏目,使用异步加载,视图代码只有一行。

复制代码 代码如下:

    这里从[anageTreeChildrenJson]action获取的json数据。

    在【CategoryController】添加JsonResult类型的[anageTreeChildrenJson]

    /// 
        /// 子栏目树形控件Json数据
        /// 
        /// 栏目id
        /// 
        [AdminAuthorize]
        public JsonResult ManageTreeChildrenJson(int id = 0)
        {
          categoryRsy = new CategoryRepository();
          var _children = categoryRsy.Children(id);
          List _trees = new List(_children.Count());
          foreach(var c in _children)
          {
            Tree _t = new Tree { id = c.CategoryId, text = c.Name};
            switch (c.Type)
            {
              case 0:
                _t.state = "closed";
                _t.iconCls = "icon-general";
                break;
              case 1:
                _t.state = "open";
                _t.iconCls = "icon-page";
                break;
              case 2:
                _t.state = "open";
                _t.iconCls = "icon-link";
                break;
            }
            _trees.Add(_t);
          }
          return Json(_trees, JsonRequestBehavior.AllowGet);
        }

    这里默认id=0,根据id查找子栏目,然后遍历子栏目生成树的节点数据。

    switch (c.Type) 是根据栏目类型不同来,来设置节点状态并,设置不同的图标。最后以Json类型返回。

    修改一下上一节中添加栏目的视图ManageAdd.cshtml,将左侧列表替换成@Html.Action("ManagePartialTree", "Category")。替换后ManageAdd.cshtml

    @model Ninesky.Models.Category
    
    @{
      ViewBag.Title = "ManageAdd";
      Layout = "~/Views/Layout/_Manage.cshtml";
    }
    
    
    
    添加栏目
    @using (Html.BeginForm()) { @Html.ValidationSummary(true)
    栏目
    • @Html.LabelFor(model => model.Type)
      @Html.DropDownList("Type") @Html.ValidationMessageFor(model => model.Type) @Html.DisplayDescriptionFor(model => model.Type)
    • @Html.LabelFor(model => model.Name)
      @Html.EditorFor(model => model.Name) @Html.ValidationMessageFor(model => model.Name) @Html.DisplayDescriptionFor(model => model.Name)
    • @Html.LabelFor(model => model.ParentId)
      @Html.TextBox("ParentId", 0, new { @class = "easyui-combotree", data_options = "url:'" + Url.Action("JsonTreeParent", "Category") + "'" }) @Html.ValidationMessageFor(model => model.ParentId) @Html.DisplayDescriptionFor(model => model.ParentId)
    • @Html.LabelFor(model => model.Model)
      @Html.DropDownList("Model") @Html.ValidationMessageFor(model => model.Model) @Html.DisplayDescriptionFor(model => model.Model)
    • @Html.LabelFor(model => model.CategoryView)
      @Html.EditorFor(model => model.CategoryView) @Html.ValidationMessageFor(model => model.CategoryView) @Html.DisplayDescriptionFor(model => model.CategoryView)
    • @Html.LabelFor(model => model.ContentView)
      @Html.EditorFor(model => model.ContentView) @Html.ValidationMessageFor(model => model.ContentView) @Html.DisplayDescriptionFor(model => model.ContentView)
    • @Html.LabelFor(model => model.Navigation)
      @Html.EditorFor(model => model.Navigation) @Html.ValidationMessageFor(model => model.Navigation) @Html.DisplayDescriptionFor(model => model.Navigation)
    • @Html.LabelFor(model => model.Order)
      @Html.EditorFor(model => model.Order, new { value = 0 }) @Html.ValidationMessageFor(model => model.Order) @Html.DisplayDescriptionFor(model => model.Order)
    }
    @Html.Action("ManagePartialTree", "Category")
    @section Scripts { @Styles.Render("~/EasyUi/icon") @Scripts.Render("~/bundles/EasyUi") @Scripts.Render("~/bundles/jqueryval") }

    添加一个单页类型节点,在添加一个链接类型节点看一下

    点一下栏目树前的小箭头能够显示和关闭下级栏目。但点栏目名称没什么反应,我希望的是点栏目名称能够跳转到栏目详细信息页面~/Category/ManageDetails/id,现在用js实现。打开ManagePartialTree.cshtml,在下面添加脚本。

    
    
    

    完工。

    以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
