一周代码秀之[11.18~11.24 linq2xml面向对象]

1、xml

  <Sections>

    <Item key ="1" value ="孕哺期" canBeSelected="false">

      <Child key ="6" value ="备孕期"/>

      <Child key ="7" value ="怀孕期"/>

      <Child key ="8" value ="分娩期" />

    </Item>

    <Item key ="2" value ="0 - 6月"/>

    <Item key ="3" value ="7 - 12月"/>

    <Item key ="4" value ="1 - 3岁"/>

    <Item key ="5" value ="4 - 6岁"/>

  </Sections>

2、提取类

    public class ParentItem

    {

        public int Key { get; set; }

        public string Value { get; set; }

        public bool canBeSelected { get; set; }

        public List<Child> Children { get; set; }

    }

    public class Child

    {

        public int Key { get; set; }

        public string Value { get; set; }

    }

3、linq读取xml，并将其填充实体集合

   string menuPath = System.Web.HttpContext.Current.Request.PhysicalApplicationPath + "/Files/Config/BaseConfig.xml";

            XDocument doc = XDocument.Load(menuPath);

            var listP = from x in doc.Descendants("Sections").Elements("Item")

                        select new ParentItem

                        {

                            canBeSelected = false,

                            Key = (int)x.Attribute("key"),

                            Value = (string)x.Attribute("value"),

                            Children =

                                 (

                                  from t in x.Descendants("Child")

                                  select new Child

                                  {

                                      Key = (int)t.Attribute("key"),

                                      Value = (string)t.Attribute("value")

                                  }



                                ).ToList()

                        };

4、easyui combobox的绑定的默认json格式

[{

    "id":1,

    "text":"Folder1",

    "iconCls":"icon-ok",

    "children":[{

        "id":2,

        "text":"File1",

        "checked":true

    }

]

5、 linq构建conbobox的json格式

  var jsonData = from p in listP

                           select new

                           {

                               id = p.Key,

                               text = p.Value,

                               ischecked = selectedNode.Split(',').Contains(p.Key.ToString()) ? true : false,

                               children = from c in p.Children

                                          select new

                                          {

                                              id = c.Key,

                                              text = c.Value,

                                              ischecked = selectedNode.Split(',').Contains(c.Key.ToString()) ? true : false,

                                          }



                           };

            JavaScriptSerializer jss = new JavaScriptSerializer();



            string firstNode = (selectedNode == "-1" || selectedNode.Trim() == "") ? "[{\"id\":-1,\"checked\":true,\"text\":\"--请选择--\"}," : "[{\"id\":-1,\"text\":\"--请选择--\"},";

            if (selectedNode.Trim() == "noheader")

            {

                return jss.Serialize(jsonData).Replace("ischecked", "checked");

            }

            return firstNode + jss.Serialize(jsonData).Substring(1).Replace("ischecked", "checked");

6、前端代码

 <select class="easyui-combotree" id="txtSection"> 

  </select>



 $('#txtSection').combotree({

                url: "AddEditKnowledges.aspx?action=load",

                valueField: 'id',

                textField: 'text',

                onClick: function (node) {

                    // alert(node.text + ":" + node.id);

                    if (node.text != '孕哺期') {

                        $("#hdnSection").val(node.id);

                    }

                }

});
