根据特定的json格式生成无限级树形菜单效果

使用方法：

引入CSS样式

<!--图标样式-->
<link rel="stylesheet" type="text/css" href="css/bootstrap.min.css"/>
<!--主要样式-->
<link rel="stylesheet" type="text/css" href="css/style.css"/>

引入jQuery库文件、插件JS文件

<script type="text/javascript" src="js/jquery-1.7.2.min.js"></script>
<script type="text/javascript" src="js/test.js"></script>

插件初始化、参数配置

$(function () {
	$('.tree li:has(ul)').addClass('parent_li').find(' > span').attr('title', '关闭');
	$('.tree li.parent_li > span').on('click', function (e) {
		var children = $(this).parent('li.parent_li').find(' > ul > li');
		if (children.is(":visible")) {
			children.hide('fast');
			$(this).attr('title', '展开').find(' > i').addClass('icon-plus-sign').removeClass('icon-minus-sign');
		} else {
			children.show('fast');
			$(this).attr('title', '关闭').find(' > i').addClass('icon-minus-sign').removeClass('icon-plus-sign');
		}
		e.stopPropagation();
	});
});

Json 格式

var json = [{
    "name": "中科慈航",
    "code": "ZKCH",
    "icon": "icon-th",
    "child": [{
        "name": "广州中科慈航",
        "icon": "icon-minus-sign",
        "code": "GZZKCH",
        "parentCode": "ZKCH",
        "child": [{
            "name": "广州中科慈航天河区分行",
            "code": "GZZKCHTQFH",
            "icon": "",
            "parentCode": "GZZKCH",
            "child": []
        }]
    },
    {
        "name": "北京中科慈航",
        "icon": "",
        "code": "BJZKCH",
        "parentCode": "ZKCH",

    }]
},
{
