html+css3+jquery多级目录树型结构菜单
1、准备好需要用到的图标。
2、新建html文档。
3、书写hmtl代码。
<div class="htmleaf-container">
<div class="htmleaf-content">
<h2>带日志JS多级目录树结构特效</h2>
<button onClick="expand_all()">扩大所有节点</button>
<button onClick="collapse_all()">所有节点崩溃</button>
<button onClick="clear_log()">清除日志</button>
<br/><br/>
<div id="div_log"></div>
<div id="div_tree"></div>
</div>
</div>
4、书写css代码。
body { font-family: 'Helvetica Neue', Helvetica, 'Segoe UI', Arial, freesans; }
#div_tree { font: 10px Verdana, sans-serif; display: inline-block; width: 300px; }
#div_log { width: 400px; height: 400px; overflow: scroll; padding: 10px; vertical-align: top; display: inline-block; border: 1px solid gray; font: 10px Verdana, sans-serif; line-height: 16px; }
ul.tree, ul.tree ul { list-style-type: none; background: url(vline.png) repeat-y; margin: 0; padding: 0; padding-left: 7px; -webkit-user-select: none; -moz-user-select: none; -ms-user-select: none; cursor: default; }
li.last { background-image: 'url("css/lastnode.png")'; background-repeat: no-repeat; }
ul.tree ul { padding-left: 7px; }
ul.tree li { margin: 0; padding: 0 12px; line-height: 22px; background: url(node.png) no-repeat; }
ul.tree li.last { background: #fff url(lastnode.png) no-repeat; }
img.exp_col { position: absolute; margin-top: 4px; margin-left: -20px; vertical-align: sub; }
img.exp_col_empty { position: absolute; margin-top: 4px; margin-left: -20px; vertical-align: sub; width: 16px; }
img.icon_tree { vertical-align: middle; padding-left: 3px; margin-top: -3px; }
a.node { padding: 2px; }
span.node a { padding-left: 3px; }
span.node { margin-left: -1px; padding-right: 3px; padding-top: 4px; padding-bottom: 4px; }
span.node:hover { margin-left: -1px; padding-right: 3px; padding-top: 4px; padding-bottom: 4px; background-color: #DCEDFF; border-radius: 2px; }
span.node_selected { margin-left: -2px; padding-right: 3px; padding-top: 4px; padding-bottom: 4px; background-color: #CEFFCE; border: 1px solid #8AE88A; border-radius: 2px; }
span.node_selected a { padding-left: 3px; }
.menu, .sub-menu { margin: 0; padding: 0; font: 10px Verdana, sans-serif; }
.menu, .sub-menu { list-style: none; background: #000; }
.sub-menu { background: #F1F1F1; }
.menu a { text-decoration: none; display: inline-block; padding: 8px; }
.menu span { position: absolute; width: 100%; height: 100%; }
.menu div { position: absolute; right: 4px; top: 0px; padding: 8px; }
.menu .menu_img { vertical-align: middle; }
.menu img { text-decoration: none; display: inline-block; vertical-align: sub; padding-left: 5px; }
.menu li { position: relative; }
.menu li:hover { background: aquamarine; cursor: pointer; }
.sub-menu li:hover { background: aquamarine; }
.menu li:hover > .sub-menu { display: block; }
.menu { width: 150px; position: absolute; background: #F1F1F1; -webkit-user-select: none; /* Chrome/Safari */ -moz-user-select: none; /* Firefox */ -ms-user-select: none; /* IE10+ */ cursor: default; box-shadow: 2px 2px 3px #BDBDBD; }
.sub-menu { display: none; position: absolute; min-width: 150px; box-shadow: 2px 2px 3px #BDBDBD; }
.menu .sub-menu { top: 0; left: 100%; }
5、书写并添加js代码。
<script src="lib/Aimara.js"></script>
<script>
win dow.onload = function() {
var contex_menu = {
'context1' : {
elements : [
{
text : 'Node Actions',
icon: 'images/blue_key.png',
action : function(node) {
},
submenu: {
elements : [
{
text : 'Toggle Node',
icon: 'images/leaf.png',
action : function(node) {
node.toggleNode();
}
},
{
text : 'Expand Node',
icon: 'images/leaf.png',
action : function(node) {
node.expandNode();
}
},
{
text : 'Collapse Node',
icon: 'images/leaf.png',
action : function(node) {
node.collapseNode();
}
},
{

icon: 'images/tree.png',
action : function(node) {
node.expandSubtree();
}
},
{

action : function(node) {
node.collapseSubtree();
}
},
{

action : function(node) {
node.removeNode();
}
},
]
}
},
{
text : 'Child Actions',
icon: 'images/blue_key.png',
action : function(node) {
},
submenu: {
elements : [
{
text : 'Create Child Node',
icon: 'images/add1.png',
action : function(node) {
node.createChildNode('Created',false,'images/folder.png',null,'context1');
}
},
{
text : 'Create 1000 Child Nodes',
icon: 'images/add1.png',
action : function(node) {
for (var i=0; i<1000; i++)
node.createChildNode('Created -' + i,false,'images/folder.png',null,'context1');
}
},
{
text : 'Delete Child Nodes',
icon: 'images/delete.png',
action : function(node) {
node.removeChildNodes();
}
}
]
}
}
]
}
};
tree = createTree('div_tree','white',contex_menu);
div_log = document.getElementById('div_log');
tree.nodeBeforeOpenEvent = function(node) {
div_log.innerHTML += node.text + ': Before expand event<br/>';
}
tree.nodeAfterOpenEvent = function(node) {
div_log.innerHTML += node.text + ': After expand event<br/>';
}
tree.nodeBeforeCloseEvent = function(node) {
div_log.innerHTML += node.text + ': Before collapse event<br/>';
}
for (var i=1; i<10; i++) {
node1 = tree.createNode('Level 0 - Node ' + i,false,'images/star.png',null,null,'context1');
for (var j=1; j<5; j++) {
node2 = node1.createChildNode('Level 1 - Node ' + j, false, 'images/blue_key.png',null,'context1');
for (var k=1; k<5; k++) {
node3 = node2.createChildNode('Level 2 - Node ' + k, false, 'images/monitor.png',null,'context1');
}
}
}
tree.drawTree();
tree.createNode('Real Time',false,'images/leaf.png',null,null,'context1');
};
function expand_all() {
tree.expandTree();
}
function clear_log() {
document.getElementById('div_log').innerHTML = '';
}
function collapse_all() {
tree.collapseTree();
}
</script>
6、代码整体结构。
7、查看效果。
