序 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
/// <summary>
/// 栏目列表局部树视图
/// </summary>
/// <returns></returns>
[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: <ul id="ctree" class="easyui-tree" data-options="url:'@Url.Action("ManageTreeChildrenJson", "Category")'"></ul> 这里从[anageTreeChildrenJson]action获取的json数据。 在【CategoryController】添加JsonResult类型的[anageTreeChildrenJson]
/// <summary>
/// 子栏目树形控件Json数据
/// </summary>
/// <param name="id">栏目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);
}
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";
}
<div class="workspace">
<div class="inside">

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。
<script type="text/javascript">
using("tree", function () {
$("#ctree").tree({
onClick: function (node) {
top.location ="@Url.Action("ManageDetails", "Category")/"+node.id;
}
});
});
</script>
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极客世界。 |
