一:目标
要实现用一个树形结构的展示数据,每个节点(除了根节点)前有一个checkbox,同时,点击父节点,则子节点全选或者全不选,当选中了全部子节点,父节点选中;如下图所示:
同时可以在创建的时候,让某些节点默认选中或不选中;
注:本人把显示图标改成了false(个人觉得不好看),想用图标的话可以不用修改源文件,
useIcons : false// 想用图标,值为true
二:准备工作
1. dtree 的 js css等文件可以去官网上下载:http://destroydrop.com/javascripts/tree/
2.由于本人对js文件做出了修改,其中用到了jquery的选择器,所以引入一个jquery的js文件
三:详细步骤
1.如果要想将dtree引入到java的web项目中,请首先将js文件中的 function dTree(objName) 下的this.icon 下所有的图片路径修改成自己项目可以访问到的图片路径
1 this.icon = {
2
3 root : '/dtree/img/base.gif',
4
5 folder : '/dtree/img/folder.gif',
6
7 folderOpen : '/dtree/img/folderopen.gif',
8
9 node : '/dtree/img/page.gif',
10
11 empty : '/dtree/img/empty.gif',
12
13 line : '/dtree/img/line.gif',
14
15 join : '/dtree/img/join.gif',
16
17 joinBottom : '/dtree/img/joinbottom.gif',
18
19 plus : '/dtree/img/plus.gif',
20
21 plusBottom : '/dtree/img/plusbottom.gif',
22
23 minus : '/dtree/img/minus.gif',
24
25 minusBottom : '/dtree/img/minusbottom.gif',
26
27 nlPlus : '/dtree/img/nolines_plus.gif',
28
29 nlMinus : '/dtree/img/nolines_minus.gif'
30
31 };
View Code
2.在 function dTree(objName) 下this.config最后加入一个属性 userCheckbox,默认值为 true
1 this.config = {
2
3 target : null,
4
5 folderLinks : true,
6
7 useSelection : true,
8
9 useCookies : true,
10
11 useLines : true,
12
13 useIcons : false,//我给改了,不想让显示图标,太丑了 0.0 想要的话,改成true
14
15 useStatusText : false,
16
17 closeSameLevel : false,
18
19 inOrder : false,
20
21 useCheckbox : true //新加的
22
23 }
View Code
并在 function Node(id, pid, name, url,checked ,title, target, icon, iconOpen, open) 中加入一行代码:
this.checkedStatus = checked || false;// 选中状态,默认false,不选中
1 function Node(id, pid, name, url,checked ,title, target, icon, iconOpen, open) {
2
3 this.id = id;
4
5 this.pid = pid;
6
7 this.name = name;
8
9 this.url = url;
10
11 this.checkedStatus = checked || false;// 选中状态,默认false,不选中
12
13 this.title = title;
14
15 this.target = target;
16
17 this.icon = icon;
18
19 this.iconOpen = iconOpen;
20
21 this._io = open || false;
22
23 this._is = false;
24
25 this._ls = false;
26
27 this._hc = false;
28
29 this._ai = 0;
30
31 this._p;
32
33 };
View Code
修改 dTree.prototype.add = function(id, pid, name, url, checked, title, target, icon, iconOpen, open) , 添加了一个参数 checked:是否选中
1 dTree.prototype.add = function(id, pid, name, url, checked, title, target, icon, iconOpen, open) {
2
3 this.aNodes[this.aNodes.length] = new Node(id, pid, name, url,checked ,title, target, icon, iconOpen, open);
4
5 };
View Code
3.在 dTree.prototype.node = function(node, nodeId)下 if (this.config.useIcons) {} 结束之后加入以下代码,把checkbox加入进去,(checkbox做了美化,最后修改css文件),并判断是否默认选中:
1 if(this.config.useCheckbox == true && node.id != 0){
2 str += '<label class="demo--label">'
3 + '<input type="checkbox" class="demo--radio" id="' + node.pid+ '_' + node.id
4 + '" onclick="javascript:' + this.obj + '.cc(' + node.id
5 + ',' + node.pid + ')"';
6 if (node.checkedStatus){
7 str += 'checked="checked"';
8 }
9 str += ' />'
10 + '<span class="demo--checkbox demo--radioInput"></span>'
11 + '</label>';
12 }
View Code
4. 在js文件的任意位置加入以下几个函数,为了实现父级子级 checkbox选中事件,代码中有详细注释,这里不做过多说明
1 //复选框onclick事件
2 dTree.prototype.cc=function(nodeId, nodePid){
3 //说明:checkbox的id由 nodePid + _ + nodeId 三部分组成
4 //获取当前节点的选中状态
5 var boo = $("#"+nodePid+"_"+nodeId).attr("checked");
6 //1. 判断有无子节点,如果有,则全部选中,并且递归判断子节点是否还有子节点
7 childsSelected(nodeId, boo);
8
9 //2. 获取所有同级节点,判断是否都选中,如果都选中,则父节点也要选中
10 parentsSelected(nodePid);
11 }
12
13 //递归选中父节点,参数1:父节点,参数2:选中状态
14 function parentsSelected(pid) {
15 //1. 获取所有同级checkbox的id集合
16 var siblings = getChilds(pid);
17 //由于至少还会有调用方法的那个节点本身,所以siblings里至少有一个值
18 var flag = $("#"+siblings[0]).attr("checked");
19 //如果flag为false,则不用看其他同级节点了,父节点的checkbox必然为false,为true的话,则继续看同级节点里有没有false
20 //只要有一个false,父节点都为false
21 if (flag){
22 for (var i = 1; i < siblings.length; i++){
23 if ($("#"+siblings[i]).attr("checked") != flag){
24 flag = false;
25 break;
26 }
27 }
28 }
29 // 获取父节点的选中状态 (父节点的id,_的后面部分是子节点_的前面部分)
30 var originalCheck = $("input[id$='_"+siblings[0].split("_")[0]+"']").attr("checked");
31 //如果父节点原本的选中状态和应该的选中状态不一致,则改变父节点选中状态,并递归调用本方法
32 if (originalCheck != flag){
33 $("input[id$='_"+siblings[0].split("_")[0]+"']").attr("checked", flag);
34 var parentCheckBoxId = $("input[id$='_"+siblings[0].split("_")[0]+"']").attr("id");
35 if (parentCheckBoxId != null){
36 parentsSelected(parentCheckBoxId.split("_")[0]);
37 }
38 }
39
40 }
41
42 //递归选中子节点,参数1:父节点id, 参数2:选中状态
43 function childsSelected(pid, boo) {
44 //获取所有下一级节点的checkbox的id
45 var childs = getChilds(pid);
46 if (childs.length == 0){
47 return;
48 }
49 //让所有子节点选中,并递归判断每一个子节点是否还有子节点,让每一层每一个都选中
50 for (var i = 0; i < childs.length; i++){
51 $("#"+childs[i]).attr("checked",boo);
52 childsSelected(childs[i].split("_")[1], boo);
53 }
54 }
55
56 //获取下一级子节点的id
57 function getChilds(pid){
58 var arr = new Array();
59 $("input[id^='"+pid+"_']").each(function (i,chkbox) {
60 arr.push(chkbox.id);
61 })
62 return arr;
63 }
View Code
5.之前提到过,对checkbox做出了一点美化,所以css文件的最后请加上以下代码:
1 .demo--label{display:inline-block}
2 .demo--radio{display:none}
3 .demo--radioInput{background-color:#fff;border:1px solid rgba(0,0,0,0.15);border-radius:100%;display:inline-block;height:13px;margin-right:5px;margin-top:-1px;vertical-align:middle;width:13px;line-height:1}
4 .demo--radio:checked + .demo--radioInput:after{background-color:#57ad68;border-radius:100%;content:"";display:inline-block;height:9px;margin:2px;width:9px}
5 .demo--checkbox.demo--radioInput,.demo--radio:checked + .demo--checkbox.demo--radioInput:after{border-radius:0}

四:说明
至此应该是结束了,如果按照步骤不能实现,请留言评论,咱们可以互相探讨,本人亲测好使,最后附上全部的js代码和css代码把,
(如果想让某一个节点默认选中,则设置url后面的一个参数为 true ,
d.add(1,0,'Node 1','searchTest.page',true);
这样只会影响单节点,对父节点和子节点都没有影响)
