search engine optimization Two ways to interact with PHP andjavascript

During the web page production process, how to maintain interaction between the front-end page and the
back-end CGI page without refreshing the page has always been a problem. Here are two methods I use in practice.
Method 1: Interaction through Cookies. There are three files in total, namely:
index.htm, action.php, main.htm
The principle is that the front-end page main.htm and the back-end action.php are organized through the page frame
index.htm, and the action.php page Set the width to 0, which does not affect the display. action.php puts information into cookies, and main.htm realizes interaction by reading
cookies. In main.htm, you can also control the background CGI program by re-reading action.php
.
index.htm
------------------------------------------------ ------------------

< noframes>

This page uses page frames, but your browser does not support it

------------------------------------------------- --------------------
action.php
------------------------- -------------------------------------
srand((double)microtime( )*1000000);
$result=rand(0,100);
setcookie("action",$result,time()+900,"/");
?>
---------- -------------------------------------------------- ---
main.htm
------------------------------------------------ ---------------------

The current parameter is

Reread Cookie


--------- -------------------------------------------------- ---
Method 2: Interact directly through parent.*.*. There are three files in total, namely:
index.htm, action.php, main.htm, of which index.htm is the same as the previous one.
The principle is to directly pass the
information through parent.rightFrame.test.current_cookie.value.
action.php
---------------------------------------------------------------
srand((double)microtime()*1000000);
$result=rand(0,100);
?>

---------------------------------------------------------------
main.htm
---------------------------------------------------------------

当前参数为

重新读取Cookie
