PHP DOM on Javascript

Question

Can we do

var name = <?PHP $_POST["name" ?>

on .js file?

So I want to get the $_POST value of php to make use of it in my javascript, because php lack of document.getElementById("id");

NO. You can use a global var at the php and that can be accessed at js file then. — Jai

Do you want to work with var name later on or just want to include the $_POST["name"] into the dom? Why not just writing <?php echo $_POST["name"]; ?> inside the html structure and taking that value/dom with e.g. query? — Nitro.de

As i mentioned in the comment you can use a global variable to store the value and that variable can be used in the js file:

<html>
<head>
  <script>
    var name = '<?php echo $_POST["name"]; ?>'; // <---should be wrapped in quotes
  </script>
  <script src="jsfile.js"></script>
</head>
<body></body>
</html>

Now in the js file you can make a reference to this variable:

var user = name; // window.name;
