HTML

<html>
<head>
<meta charset="UTF-8">
<title>ssn Checker</title>
<script type="text/javascript">
var Pattern= (\d+(\.\d+)?%);
 
function checkPercentage(Percentage){
    if (Pattern.test(Percentage)) {
        alert("VALID Percentage");
    } else {
        alert("INVALID Percentage");
    }
}
</script>
</meta></head>
<body>
    <form  önsubmit="return false;">
        <input type="text" name="Percentage" size="20">
        <input type="button" value="Check">
            onclick="checkPercentage(this.form.Percentage.value);">
    </input></input></form>
</body>
</html>

Second way, You can use Dotnet validation control(regular expression). Define your regex expression in the properties and Customize it as per your requirement.

Regular expression for your query:
(\d+(\.\d+)?%)
^0*(100\.00|[0-9]?[0-9]\.[0-9]{2})%$
