Initially, I had a JavaScript code in my HTML page. However, I decided to move the script to an external JavaScript file named jful.js.
<script type="text/javascript>
$(function() {
// Determine the initial top offset of the navigation bar
var sticky_navigation_offset_top = $('#catnav').offset().top;
// Function to determine if the navigation bar should have a "fixed" position or not
var sticky_navigation = function(){
var scroll_top = $(window).scrollTop();
// Change the position of the navigation bar based on scroll position
if (scroll_top > sticky_navigation_offset_top) {
$('#catnav').css({ 'position': 'fixed', 'top':0, 'left':0 });
} else {
$('#catnav').css({ 'position': 'relative' });
}
};
// Run the function when the page loads
sticky_navigation();
// Run the function every time the user scrolls
$(window).scroll(function() {
sticky_navigation();
});
});
</script>
However, after moving the script to an external file, the script stopped working. Below is how I included the script in my HTML document:
<head><script src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js"></script>
<script type="text/javascript" src="jful.js"></script></head>
Surprisingly, when I added the script directly to the HTML document again, it started working as expected (the script executes when scrolling down the page). What could be causing this issue?
