Note: pages in the framework cannot be cross-origin!

Assume there are two pages in the same domain.

The index.html file contains an IFRAME:

XML/html code
<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en"

Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd>
<HTML xmlns = "http://www.w3.org/1999/xhtml">
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312"/>
<Title> homepage </title>
</Head>

<Body>
<IFRAME src = "iframe.html" id = "koyoz" Height = "0" width = "0"> </iframe>
</Body>
</Html>
Iframe.html content:

XML/html code
<! Doctype HTML public "-// W3C // dtd xhtml 1.0 transitional // en"

Http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd>
<HTML xmlns = "http://www.w3.org/1999/xhtml">
<Head>
<Meta http-equiv = "Content-Type" content = "text/html; charset = gb2312"/>
<Title> iframe.html </title>
</Head>

<Body>
<Div id = "test"> www.koyoz.com </div>
</Body>
</Html>

1. Execute JS access in index.html:

JavaScript code
Document.getelementbyid('koyoz'{.content}w.doc ument. getelementbyid

('Test'). style. Color = 'red'
Access the IFRAME page with the ID 'koyoz' in index.html and obtain

Object, and set its color to red.

This code has been tested and supports IE/Firefox.

2. Access through jquery in index.html:

JavaScript code
$ ("# Koyoz"). Contents (). Find ("# test" ).css ('color', 'red ');
The effect of this Code is the same as that of direct access to JS. Because of the jquery framework, the code is shorter.
