一个层的定位有关问题
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].;

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:

Inline frames are called iframes in HTML. A label specifies a rectangular area within the content where the browser can display different documents with scroll bars and borders. To embed another document within the current HTML document, use inline frames. A reference to an element can be specified using the HTMLiframe name attribute. In JavaScript, references to elements are also made using the name attribute. An iframe is essentially used to display a web page within the currently displayed web page.

The data-id in an iframe refers to a custom attribute used in HTML tags to store the identifier of a specific element. By using the data-id attribute, you can add a unique identifier to the iframe element so that it can be manipulated and accessed in JavaScript. The naming of the data-id attribute can be customized according to specific needs, but some naming conventions are usually followed to ensure its uniqueness and readability. The data-id attribute can also be used to identify and manipulate a specific iframe.

The reasons for slow loading of iframes mainly include network delay, long resource loading time, loading order, caching mechanism and security policy. Detailed introduction: 1. Network delay. When the browser loads a web page containing an iframe, it needs to send a request to the server to obtain the content in the iframe. If the network delay is high, the time to obtain the content will increase, resulting in slow loading of the iframe. ; 2. When the resource loading time is long, the size of the resource is large or the server response time is long, the loading speed will be more obviously slower; 3. Loading sequence, etc.

Technologies that can replace iframes include Ajax, JavaScript libraries or frameworks, Web component technologies, front-end routing, and server-side rendering. Detailed introduction: 1. Ajax is a technology used to create dynamic web pages. It can realize asynchronous update of the page by exchanging data with the server in the background without refreshing the entire page. Using Ajax can load and display content more flexibly, and there is no need to use iframe to embed other pages; 2. JavaScript library or framework , such as React and so on.
