使用 javascript 回调获取密钥，如谷歌 map api 做

Question

I have a script.js file which listen various events (click, right click, copy page contact, etc). I add this script.js file in index.php file which is on different server using <script src="script.js"> tag.

Here, I pass key on that script tag such as, <script src="script.js?key=134"> to differentiate customers who use script.js file. So different server or customer has different keys.

I want to return that key back from index.php server file to script.js file on each event happen.

How can I return that key to the server to that script.js file on each event happen?

Answer 1

Could you perhaps have a script tag above this one like the following?

<script>
var CONFIG = {
    key: <?php echo $key; ?>
}
</script>

And then you can access CONFIG.key in your script.js.
