If it's a multi-page app.
Then you can re-export the variable to the front end in the querystring back end.
http://url/a?key=value
If it's a single page app, we recommend using the history API
pushStatepopStateand thereplaceState

There are two modes of delivery

The first, explicit

Passed through the URL query string, http://dict.youdao.com/search?q=中国 for example, where the q argument is passed

The second type, implicit

Through the session in PHP, the content to be passed is pre-saved in the PHP session, the page after the jump to the next page to take the value of the session

In PHP:
$_get An array of variables passed to the current script through the URL parameter.
$_post An array of variables passed to the current script via the HTTP POST method.

So, you can pass the variable that you want to pass to the next page either through the URL or through the form post to the next page.

Criticize:

You think $mes will get the result of this JS implementation, which shows that you are too weak basic skills, or it is necessary to fill the basic knowledge.
