jQuery/JavaScript:访问 iframe 的内容 [英] jQuery/JavaScript: accessing contents of an iframe
问题描述
我想使用 jQuery 在 iframe 中操作 HTML.
I would like to manipulate the HTML inside an iframe using jQuery.
我想我可以通过将 jQuery 函数的上下文设置为 iframe 的文档来做到这一点,例如:
I thought I'd be able to do this by setting the context of the jQuery function to be the document of the iframe, something like:
$(function(){ //document ready
$('some selector', frames['nameOfMyIframe'].document).doStuff()
});
但是这似乎不起作用.一些检查表明 frames['nameOfMyIframe']
中的变量是 undefined
除非我等待 iframe 加载一段时间.但是,当 iframe 加载时,变量不可访问(我收到 permission denied
类型的错误).
However this doesn't seem to work. A bit of inspection shows me that the variables in frames['nameOfMyIframe']
are undefined
unless I wait a while for the iframe to load. However, when the iframe loads the variables are not accessible (I get permission denied
-type errors).
有没有人知道解决这个问题的方法?
Does anyone know of a work-around to this?
推荐答案
我认为你正在做的事情取决于 同源策略.这应该是您收到权限被拒绝类型错误的原因.
I think what you are doing is subject to the same origin policy. This should be the reason why you are getting permission denied type errors.
