JavaScript Not Loading After PHP Header() Redirect

I have a page where a user can sign in by submitting a basic form, the data is sent to a separate PHP script (for validation, etc). The PHP script ends with the header() function t

Solution 1:

the javascript reference should be at the bottom of the HTML page before the closing body tag. Just cut the reference of the javascript to the the page bottom below:

<script type="text/javascript" src="resources/script.js"></script>
</body>
</html>

The problem is that jquery got rendered before your page load.
