在HTML页面中查找加载到iFrame中的当前网址 [英] Find current url loaded into iFrame inside html page
问题描述
我有一个简单的HTML页面，在其中有一个iFrame.以下是此代码段.
I am having a simple HTML page, inside which i have an iFrame. below is the code snippet for this.
<html>
<head></head>
<body>
<input id="currentSrc" type="text" value="" />
<iframe id="myframe" src="http://www.bing.com">
<p>your browser doesn''t support iframes
</p></iframe>
</body>
</html>
现在我想要的是，当用户单击iframe或在iframe内进行任何导致框架加载新页面的活动时，文本框"currentSrc"应填充iframe内页面的当前URL.
我试图用$("myframe").attr("src")获取url，但是它总是返回"bing.com" ...在谷歌搜索后，我发现了两个属性，如contentWindow和contentDocument，即使它们包含正确的url但由于跨域访问而给出权限被拒绝"例外.我想知道是否有任何方法可以使用jquery，json或jsonp来解决此问题.
请帮助，任何指导将不胜感激.预先感谢.
now what i want is, that when ever user clicks or does any activity inside the iframe which causes the frame to load a new page then the text box "currentSrc" should get populated with current url of the page inside iframe.
i have tried getting the url with $("myframe").attr(''src'') but it always returns "bing.com"... After googling i found two properties like contentWindow and contentDocument which even though contain proper urls but gives "Permission denied" exception because of cross domain access. I wonder if there is any way may be using jquery, json or jsonp to get a work around this.
Please help, any guidance will be highly appreciated. Thanks in advance.

更改位置并重新加载框架内容时，属性"src"不会更改(因此，我确认了您的问题).而是尝试使用框架的contentDocument.您需要处理框架的事件"onload".

The property "src" does not change when you change location and reload the frame content (so I confirm your problem). Instead, try to usecontentDocumentof the frame. You need to handle the frame''s event "onload".
