Many tutorials and demos i saw. but when view source code, it seems that to make the ajax load must create it's own code in the website itself, not just insert the code into existing web hosting. Because it should create parent and child file. See the tutorial at
http://josephbeeson.com/index.php?mact=News,cntnt01,detail,0&cntnt01articleid=2&cntnt01returnid=17. So it imposible to easily insert the ajax load code into custom code area in an existing website which has internal page editor like
http://www.heypy.com/page/page/new . Please prove that i'm wrong and show other demos if i was wrong. Thanks.
