- 樹型菜單是我們在開發(fā)中經(jīng)常用到的數(shù)據(jù)組合和顯示方式,
- dTree(http://www./javascripts/tree/)
- dTree是一種免費(fèi)的javascript樹型菜單, 它支持ie5+, ns 6+, Opera 7+以及Mozilla瀏覽器
- 使用簡單:
- 引入樹, 在head中加入dtree.js和dtree.css(注意要把js,css和img放到相應(yīng)目錄), 如下所示:
- <link rel="StyleSheet" href="dtree.css" type="text/css" />
- <script type="text/javascript" src="dtree.js"></script>
- 實(shí)例化樹并顯示
- <div class="dtree">
-
- <p><a href="javascript: d.openAll();">open all</a> | <a href="javascript: d.closeAll();">close all</a></p>
-
- <script type="text/javascript">
- <!--
-
- d = new dTree('d');
-
- d.add(0,-1,'My example tree');
- d.add(1,0,'Node 1','example01.html');
- d.add(2,0,'Node 2','example01.html');
- d.add(3,1,'Node 1.1','example01.html');
- d.add(4,0,'Node 3','example01.html');
- d.add(5,3,'Node 1.1.1','example01.html');
- d.add(6,5,'Node 1.1.1.1','example01.html');
- d.add(7,0,'Node 4','example01.html');
- d.add(8,1,'Node 1.2','example01.html');
- d.add(9,0,'My Pictures','example01.html','Pictures I\'ve taken over the years','','','img/imgfolder.gif');
- d.add(10,9,'The trip to Iceland','example01.html','Pictures of Gullfoss and Geysir');
- d.add(11,9,'Mom\'s birthday','example01.html');
- d.add(12,0,'Recycle Bin','example01.html','','','img/trash.gif');
- d.add(13,12,'sub Recycle Bin','','','','img/trash.gif');
-
- document.write(d);
-
- //-->
- </script>
-
- </div>
- add方法的參數(shù)說明 id:當(dāng)前節(jié)點(diǎn)標(biāo)識, pid:父節(jié)點(diǎn)標(biāo)識, name:當(dāng)前節(jié)點(diǎn)名字, url:當(dāng)菜單被點(diǎn)擊時(shí)響應(yīng)的超鏈接, title:提示語,
- target:在目標(biāo)窗口打開鏈接, icon:關(guān)閉時(shí)的顯示圖標(biāo), iconOpen:打開時(shí)的顯示圖標(biāo), open:默認(rèn)的打開狀態(tài), true打開, false關(guān)閉(不過它會讀cookie, 所以有時(shí)看不出效果)
- dTree.prototype.add = function(id, pid, name, url, title, target, icon, iconOpen, open)
-
- Xtree(http://webfx./dhtml/xtree/implementation.html)
- 相對dTree來說, xTree功能要多一些, 能動(dòng)態(tài)增減樹的節(jié)點(diǎn)
- 引入樹:
- <!-- The xtree script file -->
- <script src="xtree.js"></script>
- <link type="text/css" rel="stylesheet" href="xtree.css">
- 實(shí)例化樹, 并顯示
- <div style="position: absolute; width: 200px; top: 0px; left: 0px; height: 100%; padding: 5px; overflow: auto;">
-
- <!-- js file containing the tree content, edit this file to alter the menu,
- the menu will be inserted where this tag is located in the document -->
- <script>
- if (document.getElementById) {
- var tree = new WebFXTree('Root');
- tree.setBehavior('classic');
- var a = new WebFXTreeItem('1');
- tree.add(a);

- f.add(new WebFXTreeItem('1.1.4.2'));
- f.add(new WebFXTreeItem('1.1.4.3'));
- var c = new WebFXTreeItem('1.2');
- a.add(c);
- c.add(new WebFXTreeItem('1.5.1'));
- c.add(new WebFXTreeItem('1.5.2'));
- c.add(new WebFXTreeItem('1.5.3'));
- a.add(new WebFXTreeItem('1.3'));
- a.add(new WebFXTreeItem('1.4'));
- a.add(new WebFXTreeItem('1.5'));
- var d = new WebFXTreeItem('2');
- tree.add(d);
- var e = new WebFXTreeItem('2.1');
- d.add(e);
- e.add(new WebFXTreeItem('2.1.1'));
- e.add(new WebFXTreeItem('2.1.2'));
- e.add(new WebFXTreeItem('2.1.3'));
- d.add(new WebFXTreeItem('2.2'));
- d.add(new WebFXTreeItem('2.3'));
- d.add(new WebFXTreeItem('2.4'));
- document.write(tree);

-
- function delNode() {
- if (tree.getSelected()) {

- </script>
-
- </div>
-
- 打開關(guān)閉節(jié)點(diǎn):tree.toggle()
- 打開節(jié)點(diǎn):tree.expand();
- 關(guān)閉節(jié)點(diǎn):tree.collapse();
- 打開所有節(jié)點(diǎn):tree.expandAll();
- 關(guān)閉所有節(jié)點(diǎn):tree.collapseAll();
- 打開子節(jié)點(diǎn):tree.expandChildren();
- 關(guān)閉子節(jié)點(diǎn):tree.collapseChildren();
- 顯示當(dāng)前節(jié)點(diǎn)的id:if (tree.getSelected()) { alert(tree.getSelected().id); }
- 增加節(jié)點(diǎn):addNode()
- 增加多個(gè)節(jié)點(diǎn):addNodes()
- 刪除節(jié)點(diǎn):delNode()
