求助一个层的定位问题
一个后台页面,
内空页面是在一个iframe里面显示的。
现在在内容页面,要加一个浮动层(显示一个等待的效果)。
结果那一个层只覆盖了内容页框架的内容。
我的要示是:覆盖整个页面,(也就是说,浮动层可以覆盖框架外的内容),
我该怎么做。
我想这样写了
- CSS code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> #load{padding:10px; width:600px;height:300px; display:block; position: absolute; top:50%; left:50%; margin-left:-300px; margin-top:-150px;}
JS 是这样写的。
$("#load").css("display","block");
$("#img_load")[0].;
------解决方案--------------------
jquery 直接用div 弹出插件.设置 插件弹出的比例即可...不过 我忘记了那插件名字了.嘿嘿

O(∩_∩)O哈哈~,我刚刚做了这个项目,给你点经验:
jQuery 操作IFRAME
DOM方法:
父窗口操作其下的IFRAME:window.frames["iframeName"].document
或者直接写frames["iframeName"].document
IFRAME操作父窗口: window.parent.document
或者直接写parent.document
jquery方法:
在父窗口中操作 其下IFRAME中的元素: $(window.frames["iframeName"].document).find(”:text”);
在IFRAME中操作 选中父窗口中的所有输入框:$(window.parent.document).find(”:text”);
使用find可以找到自己想要的东东。
想要找到同级的iframe,可以用$(parent.frames["iframeName"]).find("xxxxxx")
细心的朋友一下就能理解,原理其实很简单,就是用到了$(DOM对象)转换成jquery对象。
例子:
- HTML code
<!--index.php--> <script type="text/javascript"></script> <div id="ifr"> <iframe id="iframe" name="showMap" width="100%" height="600" src="map.php"></iframe> <br><font color="#e78608">------解决方案--------------------</font><br>你们要是真心的帮助LZ,那么就请贴出可供测试的代码<br>否则,我就要将此贴移动了 <br><font color="#e78608">------解决方案--------------------</font><br>好吧,我承认是着急了点,还是把上面的帖子移除吧,这是个可测试的:<br>在iframe的父级页面和元素页面必须都连接上<script type="text/javascript" src="jquery_1.4.2.js"></script> 才管用<br><dl class="code">HTML code<pre class="brush:php;toolbar:false"> <!--index.html--> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>无标题文档</title> <script type="text/javascript" src="jquery_1.4.2.js"></script> <div id="show3dmap" style="border:solid 1px">此div的宽高与body相当 <div id="ifr"> <iframe id="iframe" name="show" width="100%" height="600" src="cont.html"></iframe> </div> </div> <!--cont.html--> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title>无标题文档</title> <script type="text/javascript" src="jquery_1.4.2.js"></script> <div>这是子页面 <input type="button" id="full" value="点击覆盖"> <input type="button" id="replace" value="点击替换父级div"> </div> <script> $("#replace").live("click",function(){ $(window.parent.document).find("#iframe").css({'display':'none','visibility':'hidden'}); $(window.parent.document).find("#show3dmap").html("<div id='rep' style='width:1200px;height:1000px;z-index:2;'>"+ "这里替换内容</script>
可定义按钮来关闭此div:

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
