创建超链接 基准URL标签<base> 超链接的类型 内部链接 外部链接 书签链接 脚本链接 文件下载 若链接的目标文档类型属于doc,rsr,cab,zip,exe等时，可以获得文件下载链接 文本链接 图片链接 超链接与浮动框架 在页面中嵌入浮动框架 浮动框架就像HTML页面中的其他对象一样，可以出现在页面中任何一个位置，但与其他对象不同的是浮动框架在页面中构建了一个 区域，这个区域可以显示另一个HTML页面的内容，区域中显示的页面使用浮动框架的属性src来指定。 基本语法： <iframe src="源文件地址" width="宽度" height="高度"></iframe> 设置浮动框架大小 基本语法： <iframe src="源文件地址" width="宽度" height="高度"></iframe> 设置浮动框架的边框 默认情况下，浮动框架会显示边框。 基本语法： <iframe frameborder="0|1"></iframe> 取1显示边框；取0则不显示边框。 浮动框架作为超链接目标 例子-超链接的使用 <!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>超链接的使用</title> </head> <body> <a href="https://blog.csdn.net/weixin

CSRF攻击

django攻击 csrf攻击 xss攻击 clickjacking攻击 sql注入 CSRF攻击： CSRF攻击概述： CSRF（Cross Site Request Forgery, 跨站域请求伪造）是一种网络的攻击方式，它在 2007 年曾被列为互联网 20 大安全隐患之一。其他安全隐患，比如 SQL 脚本注入，跨站域脚本攻击等在近年来已经逐渐为众人熟知，很多网站也都针对他们进行了防御。然而，对于大多数人来说，CSRF 却依然是一个陌生的概念。即便是大名鼎鼎的 Gmail, 在 2007 年底也存在着 CSRF 漏洞，从而被黑客攻击而使 Gmail 的用户造成巨大的损失。 CSRF攻击原理： 网站是通过 cookie 来实现登录功能的。而 cookie 只要存在浏览器中，那么浏览器在访问这个 cookie 的服务器的时候，就会自动的携带 cookie 信息到服务器上去。那么这时候就存在一个漏洞了，如果你访问了一个别有用心或病毒网站，这个网站可以在网页源代码中插入js代码，使用js代码给其他服务器发送请求（比如ICBC的转账请求）。那么因为在发送请求的时候，浏览器会自动的把 cookie 发送给对应的服务器，这时候相应的服务器（比如ICBC网站），就不知道这个请求是伪造的，就被欺骗过去了。从而达到在用户不知情的情况下，给某个服务器发送了一个请求（比如转账）。 防御CSRF攻击：

问题 Using javascript with jQuery, I am adding an iframe with a youtube url to display a video on a website however the embed code that gets loaded in the iframe from youtube doesnt have wmode="Opaque", therefore the modal boxes on the page are shown beneath the youtube video.

If it doesn't work try this instead, &wmode=transparent which will work in IE browser as well. 回答2:

问题 I have a UI widget that needs to be put in an IFRAME both for performance reasons and so we can syndicate it out to affiliate sites easily. The UI for the widget includes tool-tips that display over the top of other page content. See screenshot below or go to the site to see it in action. Is there any way to make content from within the IFRAME overlap the parent frame's content? 回答1: No it's not possible. Ignoring any historical reasons, nowadays it would be considered a security

iframe 自适应

<iframe src="http://www.fulibac.com" id="myiframe" scrolling="no" onload="changeFrameHeight()" frameborder="0"></iframe> js代码也得跟着改 function changeFrameHeight(){ var ifm= document.getElementById("iframepage"); ifm.height=document.documentElement.clientHeight; } window.onresize=function(){ changeFrameHeight(); } window.onresize的作用就是当窗口大小改变的时候会触发这个事件。 所以，使用方法二就可以完美的、真正的让iframe自适应高度了，试试看吧，并且兼容多种浏览器。 来源： https://www.cnblogs.com/wjwen/p/6430418.html
