Iframe pages are embedded in the parent page. Generally, iframe pages are used by default for relevant actions in the iframe, which does not affect the parent page. What should I do if I need to operate the elements of the parent page on the Child pages of iframe?
To operate the parent page element on the iframe sub-page, you need to know the following two points:
(1) The iframe subpage and parent page must belong to the same domain.
(2) The object method for retrieving the parent page from the iframe page is parent.
Example:
<Body>
<Div id = "test"> </div>
<Iframe src = "http://www.phpernote.com/javascript-function/272.html"> </iframe>
</Body>
In the http://www.phpernote.com/javascript-function/272.html page, add the "iframe child Page Operation parent page element" to the content of the id = "test" element of the parent page as follows:
Parent.doc ument. getElementById ('map _ position'). innerHTML = 'iframe sub-page operation parent page element ';
Similarly, if you need to refresh the parent page on the Child page, you can use: parent. location. reload ();
