Use the window.location.href Property
You can use the JavaScript window.location.href property to get the entire URL of the current page which includes host name, query string, fragment identifier, etc.

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Get Current URL in JavaScript</title>
</head>
<body>
<script>
function getURL() {
alert("The URL of this page is: " + window.location.href);
}
</script>
<button type="button" onclick="getURL();">Get Page URL</button>
</body>
</html>
