JavaScript html/javascript/php: how do i use a “global variable”? html javascript global variable,html javascript global var,html javascript

You can inject any PHP value into clientside.

<script>
  var baseURL = <?php echo json_encode($baseURL); ?>;
</script>

Use json_encode because this gives foolproof safe way of delivering data in the format JS understands, and works on real arrays, PHP "arrays", numbers, strings, whatever you want.

Answer:1

try this:

<script>    
window.yourGlobalVariable = ....
</script>

by using you window it will be available for all your site
