Use jQuery to Insert HTML into an iFrame Body Tag
提问by L84
I am using a hosted CMS that renders an iFrame within another iFrames. These iFrames are loaded from the same domain but since this is a hosted CMS I do not have access to these iFrames directly. Is it possible, using jQuery, to insert HTML content into the bodytag of the iFrame with the id of re_contentIframe?
我正在使用在另一个 iFrame 中呈现 iFrame 的托管 CMS。这些 iFrame 是从同一个域加载的，但由于这是一个托管的 CMS，我无法直接访问这些 iFrame。是否可以使用 jQuery 将 HTML 内容插入bodyid 为 iFrame的标签中re_contentIframe？
Here is how the code renders on my site:
以下是代码在我的网站上的呈现方式：
<div class="editor">
<iframe id="editorf" frameborder="0" src="/ForumEditor.aspx?ForumID=2221&TopicID=-1&NoTemplate=False&Internal=False" style="display: inline;">
<html>
<head></head>
<body>
<!-- CODE -->
<iframe id="re_contentIframe" frameborder="0" src="javascript:'<html></html>';">
<html>
<head></head>
<body> <!-- THIS IS WHAT I WANT TO TARGET --> </body>
</html>
</iframe>
<!-- CODE -->
</body>
</html>
</iframe>
</div>
I tried using the following code but nothing happens with this code (including no errors):
我尝试使用以下代码，但此代码没有任何反应（包括没有错误）：
$(function() {
$( "#test" ).click(function() {
$("#re_contentIframe").contents().find("body").html("<p>new HTML content goes here</p>");
});
});

The problem is that you are trying to access a nested frame.
问题是您正在尝试访问嵌套框架。
The #re_contentIframeframe is nested within #editorf, which is subsequently nested within your document.
该#re_contentIframe框架嵌套#editorf，随后被嵌套在文档中。
Try:
尝试：
$('#re_contentIframe').contents().find('body').find('#editorf').contents()

haven't checked it ,might help :
没有检查过，可能有帮助：
var frameObject = document.getElementById('editorf');
var frameContent = frameObject.contentDocument ||
frameObject.contentWindow.document;
var insideIframe = frameContent.getElementById('re_contentIframe');
var insideIframeContent = insideIframeObject.contentDocument ||
insideIframeObject.contentWindow.document;
var $body = $('body',insideIframeContent);
$body.html('<div>contentupdated</div>');
