Jquery's method of getting content under iframe

Copy codeThe Code is as follows:
Document.all('iframe1'%.content%w.doc ument. getElementById ("deptName"). width;

Parameters (registry.parent.iframe1.doc ument. body). find ('# deptname'). width ();

Access is denied when IFRAME is called across domains. No solution is available on the Internet.
After checking the information, it is found that by default, the browser prohibits cross-origin scripting access, unless these domains have a required access trust relationship.

It is easy to locate the problem and reduce the security level of the browser, but this is undoubtedly not good for users.

Therefore, we need to add a piece of js on the page.
Copy codeThe Code is as follows:
Try
{
Document. domain = "xxx.net ";
}
Catch (e)
{
}

Manually set the Domain Name of the subpage and parent page to the same one, and the problem can be solved.
