阅读更多关于 Holy grail for determining whether or not local iframe has loaded

问题 Firstly, I see this question asked a few times but no answers seem satisfactory. What I am looking for is to be able to call a script at anytime and determine whether or not an iframe has loaded - and to not limit the script to require being added to the iframe tag itself in an onload property. Here's some background: I have been working on an unobtrusive script to try and determine whether or not local iframes in the dom have loaded, this is because one of our clients includes forms on their

问题 This question was migrated from Webmasters Stack Exchange because it can be answered on Stack Overflow. Migrated 7 years ago .

I'm totally unfamiliar with WordPress, and as technically proficient as I like to think of myself, I cannot find how to make a frame on a page that refers to another URL. There are several other pages on my site that have similar frames, but the code for those pages appears to be totally empty.

iframe.contentWindow 属性：关于contentWindow和contentDocument区分

阅读更多关于 iframe.contentWindow 属性：关于contentWindow和contentDocument区分

定义和用法　　 contentDocument 属性能够以 HTML 对象来返回 iframe 中的文档，可以通过所有标准的 DOM 方法来处理被返回的对象。　　语法：frameObject.contentWindow，或者 iframeObject.contentWindow（不是jquery对象）　　用iframe嵌套页面时，如果父页面要获取子页面里面的内容，可以使用contentWindow或者contentDocument，其区别如下：　　1、contentWindow 这是个只读属性，返回指定的iframe的窗口对象。它虽然不是标准的一部分，但各个主流浏览器都支持。　　2、contentDocument Firefox 支持，IE6，IE7都不支持，IE8开始支持,需要如此访问 document.frames['J_mainframe'].document。　　兼容获取document对象： var getIFrameDoc = function(){ var iobj = document.createElement("iframe"); document.getElementsByTagName("body")[0].appendChild(iobj); return iobj.contentDocument || iobj

HTML frame tag URL of browser not changing

阅读更多关于 HTML frame tag URL of browser not changing

问题 How do I change the URL of the browser with a website using a structure of <frame> . I know the whole point of <frame> is to use embedded frames so that you can't tell where the site is going. In particular, when you click a link, the frame changes, but the URL at the top of the browser says the same thing. I'm trying to make it so that the browser CHANGES the URL, so the real URL of the main inner frame is shown at all times. How can I do this? 回答1: You can't; best bet is to change the

问题 I was just checking to see if it was valid to put an <iframe> element inside a <noscript> element as a fall back for displaying dynamic content. It validated fine with the HTML 5 doctype, but for HTML 4.01, I get the following error: Line 9, Column 35: element "IFRAME" undefined <iframe name="test" src="test.htm"></iframe> You have used the element named above in your document, but the document type you are using does not define an element of that name. This error is often caused by:
