Easyui Tree方法扩展 - getLevel(获取节点级别)

//扩展方法



$.extend($.fn.tree.methods, {

    getLevel:function(jq,target){

        var l = $(target).parentsUntil("ul.tree","ul");

        return l.length+1;

    }

});



//用法



var node = $().tree("getSelected");

var lv =  $().tree("getLevel",node.target);
