Web网页树形列表中实现选中父节点则子节点全选和不选中父则子全不选

 
 
 
 
 
 
需要实现的功能:选中父节点对应子节点全选;不选中父节点,对应子节点也不选中
如下图所示,选中车队,对应车队中车辆也全部选中,以实现车队中所有车辆在地图上的显示。

选中cqupt1,则对应所有成员car1,car2自动选中,地图上显示车队中的所有车辆位置信息

解决办法:

车队对应的id为team_id,车辆对应的id为veh_id,在每个车队中,所有车辆对应同一个team_id

1、首先在TeamTree.aspx.cs文件中
把team_id从父节点函数中传递到子节点函数中,
再给该车队每个成员定义一个共同的标签名称team_id,这样car1/car2/car3三个车有个共同的标签team_id :
sb_TreeNode.Append("<div class='" + strclass + "'><input id='" + entity.team_id + "' type='checkbox' /><span>" + entity.team_name + "</span></div>");
选中team_id,对应的member_id都选中,并传递member_id,而不传递team_id。而上面的程序直接把id传出
对应代码如下:
 1 /// <summary>
 2         /// 创建子节点
 3         /// </summary>
 4         /// <param name="list">list</param>
 5         /// <returns></returns>
 6         public string GetTreeNode(IList list)
 7         {
 8             Info_Veh_Team info_veh_team = new Info_Veh_Team();
 9             StringBuilder sb_TreeNode = new StringBuilder();
10             List<Info_Veh_Team> itemNode = IListHelper.IListToList<Info_Veh_Team>(list);   
11   
12             int index1 = 0;
13             string strclass = "";
14             if (itemNode.Count > 0)
15             {
16                 sb_TreeNode.Append("<ul>");
17                 foreach (Info_Veh_Team entity in itemNode)
18                 {
19                     if (index1 == 0)
20                         strclass = "collapsableselected";
21                     else
22                         strclass = "";
23                     sb_TreeNode.Append("<li>");
24                     sb_TreeNode.Append("<div class='" + strclass + "'><input id='" + entity.team_id + "' type='checkbox' id1='" + index1 + "' /><span>" + entity.team_name + "</span></div>");
25                     
26                     info_veh_team = info_veh_teamibll.GetEntity(entity.team_id);
27                     StringBuilder where = new StringBuilder();
28                     where.Append("and team_id='" + info_veh_team.team_id + "'");      
29                     IList nextlist = info_team_memberibll.GetListWhere(where, null);
30                     sb_TreeNode.Append(GetTreeNodeNext(nextlist, index1));
31                     sb_TreeNode.Append("</li>");
32                     index1++;
33                 }
34                 sb_TreeNode.Append("</ul>");
35             }
36             return sb_TreeNode.ToString();
37         }
38         /// <summary>
39         /// 创建子节点
40         /// </summary>
41         /// <param name="list">list</param>
42         /// <returns></returns>
43         public string GetTreeNodeNext(IList list, int index1)
44         {
45             StringBuilder sb_TreeNode = new StringBuilder();
46             List<Info_Team_Member> itemNode = IListHelper.IListToList<Info_Team_Member>(list);
47             int index = 0;
48             string strclass = "";
49             if (itemNode.Count > 0)
50             {
51                 sb_TreeNode.Append("<ul>");
52                 foreach (Info_Team_Member entity in itemNode)
53                 {
54                     if (index == 0)
55                         strclass = "collapsableselected";
56                     else
57                         strclass = "";
58                     sb_TreeNode.Append("<li>");
59                     sb_TreeNode.Append("<div class='" + strclass + "'><input id='" + entity.member_id + "' type='checkbox'  name='" + index1 + "' id2='" + index1 + "' id3='" + entity.veh_lpn + "'/><span>" + entity.veh_lpn + "</span></div>");
60                     sb_TreeNode.Append("</li>");
61                     index++;
62                 }
63                 sb_TreeNode.Append("</ul>");
64             }
65             return sb_TreeNode.ToString();
66         }

 

2、具体的复选框选中在js里面去实现,也就是TeamTree.aspx中去实现(选中父则子全选中)
在TeamTree.aspx中,先是把复选框选中的所有元素保存到数组中,界面点击传出的选中的结果,对应实现应该勾选的各结果
$('.strTree li div input:checkbox').click(function () {//问题:如何实现选中车队,对应成员全部选中,并传对应所有成员的member_id,而不是传team_id

                team_id = document.getElementsByName($(this).attr('id1'));    //通过name   获取name='team_id'的子元素        ($(this).attr('id'))为被选中的车队名               
                team = document.getElementById($(this).attr('id')); //通过id获取   获取的是被勾选的车队或者车辆的id              
                if (team.checked) {
                    for (i = 0; i < team_id.length; i++) {
                        team_id[i].checked = true;
                    }
                } else {
                    for (i = 0; i < team_id.length; i++) {
                        team_id[i].checked = false;
                    }                  
                }
                                                                        
                //alert(team_id.length);
                var indexs = [];          
                var vehIds = [];         
                $(".strTree li div input:checkbox:checked").each(function (i) {  //由于复选框选中多个,所以循环输出
                    v = document.getElementsByName($(this).attr('id1'));
                    //alert("v的值" + v.length);
                    if (v.length == 0) {
                        //vehIds[i] = $(this).attr('id2') + "|" + $(this).attr('id3');                       
                        indexs[i] = $(this).attr('id2');
                        vehIds[i] = $(this).attr('id3');
                    } 
                    //vehIds[i] = $(this).attr('id');   //attr() 方法设置或返回被选元素的属性值            
                   
                });              
                for (var i = 0; i < indexs.length; i++) {            //清除vehIds[]中的所有空字符串
                    if (indexs[i] == '' || indexs[i] == null || typeof (indexs[i]) == undefined) {
                        indexs.splice(i, 1);
                        i = i - 1;
                    }
                }
                for (var i = 0; i < vehIds.length; i++) {            //清除vehIds[]中的所有空字符串
                    if (vehIds[i] == '' || vehIds[i] == null || typeof (vehIds[i]) == undefined) {
                        vehIds.splice(i, 1);
                        i = i - 1;
                    }
                }                                        
                self.vehIds = vehIds;
                self.indexs = indexs;
                
                var path = 'TeamMap.aspx';
                window.parent.frames['target_right'].location = path;
                Loading(true);
            });
