如何在没有AJAX，Jscript，HTML隐藏字段或cookie的情况下从JavaScript变量获取值到PHP变量？

Question

How to get a value from a JavaScript variable to a PHP variable without AJAX, Jscript, HTML hidden field, or a cookie ?

(from PHP to JavaScript: var javaScriptVar = "<?php echo $someVar; ?>"; ) So is there nothing like that?

thanks

Answer 1

You can do it like in your example, but your javascript must either be inside a script tag which is in a PHP file, or in an external 'js' file that you save with a php extension.

Or, you can set your server up so that all files with a 'js' extension also get parsed by PHP, but that's probably more than overkill.

However, since the PHP will only be executed once before the file is returned to the client, there's no way to make that dynamic. If your objective is to do something simple with data that resides on the server (and more than likely will not change between page accesses) it won't be too horrible to accomplish what you want to do that way.
