使用layui+ajax实现简单的菜单权限管理及排序的方

//菜单循环遍历打印拼接操作
  $(function () {
  $.ajax( {
   url : projectName+'/sys/menu/findMenuByRole',
   type : 'post',
   dataType : 'json',
   suess : function(data) {
   var menu = ""; //定义变量存储
   for(var i = 0;i<data.length;i++){
    menu += "<li class='layui-nav-item '>"
    if(data[i].pareMenuId == 0){ //取出父元素的菜单，拼进页面
    menu += "<a href='javascript:;'>"+data[i].menuName+"</a>"
    for(var j = 0;j<data.length;j++){ //继续遍历这几条数据
     if(data[j].mid > data[i].mid && data[j].mid < (data[i].mid)+1000){ //取出这个父元素所对应的子元素
     menu += "<dl class='layui-nav-child'>"
     menu += "<dd>"
     menu +=  "<a href='"+data[j].menuPath+"' target='option'>"+'&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'+data[j].menuName+"</a>"
     menu += "</dd>"
     menu += "</dl>"
     }
    }
    }
    menu += "</li>";
   }
   $("#nav").html(menu);
   var element = layui.element;
   element.init()//初始化element事件，使菜单展开
   }
  });
  })
