序
一、用戶
二、用戶組
三、欄目
3.1添加欄目
3.2浏覽欄目
浏覽欄目這塊做個一個樹形列表，添加欄目的左側部分只寫了句“左側列表”就是指這個樹形列表，等我們寫完替換一下就可以了。
先在【CategoryController】裡面添加[ManagePartialTree]action，這裡的Partial用來說明是分部視圖
/// <summary>
/// 欄目列表局部樹視圖
/// </summary>
/// <returns></returns>
[AdminAuthorize]
public ActionResult ManagePartialTree()
{
return View();
}
右鍵添加分部視圖ManagePartialTree.cshtml。分部視圖裡用easyui的tree來顯示欄目，使用異步加載，視圖代碼只有一行。
復制代碼 代碼如下:<ul id="ctree" class="easyui-tree" data-options="url:'@Url.Action("ManageTreeChildrenJson", "Category")'"></ul>
這裡從[anageTreeChildrenJson]action獲取的json數據。
在【CategoryController】添加JsonResult類型的[anageTreeChildrenJson]
/// <summary>
/// 子欄目樹形控件Json數據
/// </summary>
/// <param name="id">欄目id</param>
/// <returns></returns>
[AdminAuthorize]
public JsonResult ManageTreeChildrenJson(int id = 0)
{
categoryRsy = new CategoryRepository();
var _children = categoryRsy.Children(id);
List<Tree> _trees = new List<Tree>(_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);
}
這裡默認id=0，根據id查找子欄目，然後遍歷子欄目生成樹的節點數據。
switch (c.Type) 是根據欄目類型不同來，來設置節點狀態並，設置不同的圖標。最後以Json類型返回。
修改一下上一節中添加欄目的視圖ManageAdd.cshtml，將左側列表替換成@Html.Action("ManagePartialTree", "Category")。替換後ManageAdd.cshtml
@model Ninesky.Models.Category
@{
ViewBag.Title = "ManageAdd";
Layout = "~/Views/Layout/_Manage.cshtml";
}
<div class="workspace">
<div class="inside">
<div class="notebar">

$("#li_nav").show();
}
}
</script>
@section Scripts {
@Styles.Render("~/EasyUi/icon")
@Scripts.Render("~/bundles/EasyUi")
@Scripts.Render("~/bundles/jqueryval")
}
添加一個單頁類型節點，在添加一個鏈接類型節點看一下
點一下欄目樹前的小箭頭能夠顯示和關閉下級欄目。但點欄目名稱沒什麼反應，我希望的是點欄目名稱能夠跳轉到欄目詳細信息頁面~/Category/ManageDetails/id，現在用js實現。打開ManagePartialTree.cshtml，在下面添加腳本。
<script type="text/javascript">
using("tree", function () {
$("#ctree").tree({
onClick: function (node) {
top.location ="@Url.Action("ManageDetails", "Category")/"+node.id;
}
});
});
</script>
完工。
