jQuery動態(tài)添加多級收縮菜單

使用方法：

1、head引入css文件

<!--頁面布局，可忽略！-->
<link rel="stylesheet" type="text/css" href="css/m-base.css" />

<!--左側(cè)導(dǎo)航樣式-->
<link rel="stylesheet" type="text/css" href="css/LeftNav.css"/>

2、head引入js文件

<script src="js/jquery.min.js" type="text/javascript"></script>
<script src="js/LeftNav.js" type="text/javascript"></script>

3、body引入HTML代碼

<div class="left"></div>

<script>
	var menu = {
		name: '', //名字
		level:'0',
		haschildren: true, //是否有子節(jié)點
		url: '#', //url路徑
		isopen: false, //是否展開
		children: [{ //子節(jié)點
			name: '1',
			level: '1',
			haschildren: true,
			url: '',
			isopen: true,
			children: [{
				name: '1.1',
				level: '2',
				haschildren: true,
				url: '',
				isopen: true,
				children: [{
					name: '1.1.1',
					level: '3',
					haschildren: false,
					url: '14-1.html',
					isopen: true,
					children: ''
				}, {
					name: '1.1.2',
					level: '3',
					haschildren: false,
					url: '#',
					isopen: false,
					children: ''
				}]
			}]
		}, {
			name: '2',
			level: '1',
			haschildren: true,
			url: '#',
			isopen: false,
			children: [{
				name: '2.1',
				level: '2',
				haschildren: true,
				url: '#',
				isopen: false,
				children: [{
					name: '2.1.1',
					level: '3',
					haschildren: false,
					url: '#',
					isopen: false,
					children: ''
				}, {
					name: '2.1.2',
					level: '3',
					haschildren: false,
					url: '#',
					isopen: false,
					children: ''
				}]
			}, {
				name: '2.2',
				level: '2',
				haschildren: true,
				url: '#',
				isopen: false,
				children: [{
					name: '2.2.1',
					level: '3',
					haschildren: false,
					url: '#',
					isopen: false,
					children: ''
				}, {
					name: '2.2.2',
					level: '3',
					haschildren: true,
					url: '#',
					isopen: false,
					children: [{
						name: '2.2.2.1',
						level: '4',
						haschildren: true,
						url: '#',
						isopen: false,
						children: [{
							name: '2.2.2.1.1',
							level: '5',
							haschildren: false,
							url: '#',
							isopen: false,
							children: ''
						}],
					}]
				}]
			}]
		}]
	}
	//leftNav(menu)
	$.leftNav(".left",menu);
</script>
