一、前言Struts2漏洞是一个经典的漏洞系列,根源在于Struts2引入了OGNL表达式使得框架具有灵活的动态性。随着整体框架的补丁完善,现在想挖掘新的Struts2漏洞会比以前困难很多,从实际了解的情况来看,大部分用户早就修复了历史的高危漏洞。目前在做渗透测试时,Struts2漏洞主要也是碰碰运气,或者是打到内网之后用来攻击没打补丁的系统会比较有效。网上的分析文章主要从攻击利用的角度来分析这些Struts2漏洞。作为新华三攻防团队,我们的一部分工作是维护ips产品的规则库,今天回顾一下这个系

实现方法:1、用“$("img").delay(毫秒数).fadeOut()”语句,delay()设置延迟秒数;2、用“setTimeout(function(){ $("img").hide(); },毫秒值);”语句,通过定时器来延迟。

修改方法:1、用css()设置新样式,语法“$(元素).css("min-height","新值")”;2、用attr(),通过设置style属性来添加新样式,语法“$(元素).attr("style","min-height:新值")”。

区别:1、axios是一个异步请求框架,用于封装底层的XMLHttpRequest,而jquery是一个JavaScript库,只是顺便封装了dom操作;2、axios是基于承诺对象的,可以用承诺对象中的方法,而jquery不基于承诺对象。

增加元素的方法:1、用append(),语法“$("body").append(新元素)”,可向body内部的末尾处增加元素;2、用prepend(),语法“$("body").prepend(新元素)”,可向body内部的开始处增加元素。

Struts2框架的原理:1、拦截器解析请求路径;2、查找Action的完整类名;3、创建Action对象;4、执行Action方法;5、返回结果;6、视图解析。它原理基于拦截器的机制,使得业务逻辑控制器与Servlet API完全脱离开,提高了代码的可重用性和可维护性。通过使用反射机制,Struts2框架可以灵活地创建和管理Action对象,实现请求与响应的处理。

删除方法:1、用empty(),语法“$("div").empty();”,可删除所有子节点和内容;2、用children()和remove(),语法“$("div").children().remove();”,只删除子元素,不删除内容。

on()方法有4个参数:1、第一个参数不可省略,规定要从被选元素添加的一个或多个事件或命名空间;2、第二个参数可省略,规定元素的事件处理程序;3、第三个参数可省略,规定传递到函数的额外数据;4、第四个参数可省略,规定当事件发生时运行的函数。
