OK, I got this script:

HTML

<html>
<head>
<style type="text/css">
.style1 {
	text-align: center;
}
</style>
</head>

<script language="javascript" type="text/javascript">
    function buttonClick(){
    var url = document.getElementById("inputURL").value + '.html';
    window.location = url;
    }
</script>

<div class="style1">
	<br>
	<br>
	<br>


<input type="text" id="inputURL" name="inputURL" value="" style="width: 225px; height: 37px" ><br>
	<br>
<input type="button" value="click" OnClick="buttonClick()" style="width: 81px; height: 47px"/>

</div>

</html>

Now my question is, I would like to ask the user to enter *#06# then redirect them to 06.html

How do I strip the *#?

Use a regular expression:
Regular expressions - JavaScript | MDN[^]

JavaScript

function buttonClick(){
    const pattern = /^\*\#(\d+)\#$/;
    const value = document.getElementById("inputURL").value;
    if (!pattern.test(value)) {
        alert("Enter a valid URL!");
        return;
    }

    window.location = value.replace(pattern, "$1.html");
}
