- dTree是一种免费的javascript树型菜单, 它支持ie5+, ns 6+, Opera 7+以及Mozilla浏览器
- 使用简单:
- 引入树, 在head中加入dtree.js和dtree.css(注意要把js,css和img放到相应目录), 如下所示:
- <link rel="StyleSheet" href="dtree.css" type="text/css" />
- <script type="text/javascript" src="dtree.js"></script>
- 实例化树并显示
- <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方法的参数说明 id:当前节点标识, pid:父节点标识, name:当前节点名字, url:当菜单被点击时响应的超链接, title:提示语,
- target:在目标窗口打开链接, icon:关闭时的显示图标, iconOpen:打开时的显示图标, open:默认的打开状态, true打开, false关闭(不过它会读cookie, 所以有时看不出效果)
- dTree.prototype.add = function(id, pid, name, url, title, target, icon, iconOpen, open)
- Xtree(http://webfx.eae.net/dhtml/xtree/implementation.html)
- 相对dTree来说, xTree功能要多一些, 能动态增减树的节点
- 引入树:
- <!-- The xtree script file -->
- <script src="xtree.js"></script>
- <link type="text/css" rel="stylesheet" href="xtree.css">
- 实例化树, 并显示
- <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);
- var b = new WebFXTreeItem('1.1');
- a.add(b);
- b.add(new WebFXTreeItem('1.1.1'));
- b.add(new WebFXTreeItem('1.1.2'));
- b.add(new WebFXTreeItem('1.1.3'));
- var f = new WebFXTreeItem('1.1.4');
- b.add(f);
- f.add(new WebFXTreeItem('1.1.4.1'));
- 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 addNode() {
- if (tree.getSelected()) {
- tree.getSelected().add(new WebFXTreeItem('New'));
- }
- }
- function addNodes() {
- if (tree.getSelected()) {
- var foo = tree.getSelected().add(new WebFXTreeItem('New'));
- var bar = foo.add(new WebFXTreeItem('Sub 1'));
- var fbr = foo.add(new WebFXTreeItem('Sub 2'));
- }
- }
- function delNode() {
- if (tree.getSelected()) {
- tree.getSelected().remove();
- }
- }
- </script>
- </div>
- 打开关闭节点:tree.toggle()
- 打开节点:tree.expand();
- 关闭节点:tree.collapse();
- 打开所有节点:tree.expandAll();
- 关闭所有节点:tree.collapseAll();
- 打开子节点:tree.expandChildren();
- 关闭子节点:tree.collapseChildren();
- 显示当前节点的id:if (tree.getSelected()) { alert(tree.getSelected().id); }
- 增加节点:addNode()
- 增加多个节点:addNodes()
- 删除节点:delNode()
