使用Confirm（）在Javascript中执行PHP代码

Question

I am trying to use javascript's confirm function to set my php variable $continue based on the confirm click. I feel like the code below should work, but $continue is always false.

    <script type="text/javascript">
    <!--
    var answer;
    answer = confirm("Do you want to continue?");
    if (answer) { <?php $continue = true; ?> }
    else { <?php $continue = false; ?> };

    // -->
    </script>

Any help is always appreciated!

Answer 1

php is server side, javascript is client side.

if you need to change something via javascript do this using ajax. but you need keep this in your mind: the php just write html and process http requests. all of the interaction in the client side who will change some state in the server must perform a http request.
