How to correctly implement PHP and Javascript interaction_PHP tutorial

We are using

The method of PHP interacting with Javascript: interacting through cookies. There are three files in total, namely:

index.htm, action.php, main.htm

The principle is that the front page main.htm and the background action.php pass through the page frame, index. Htm is organized and the page width of action.php is set 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.

Implementation code for interaction between PHP and Javascript:

</ol>

The above is the specific implementation method for interaction between PHP and Javascript.
