<html>
<head>
<title>Currency validation using regex</title>
<script type="text/javascript">
    function validate() {
        var currency = document.getElementById("currency").value;
        var pattern = /^\d+(?:\.\d{0,2})$/ ;
        if (pattern.test(currency)) {
            alert("Currency is in valid format");
            return true;
        } 
            alert("Currency is not in valid format!Enter in 00.00 format");
            return false;

    }
</script>

</head>
<body>
<h2>Validating Currency..</h2>
Enter Currency:
<input type="text" name="currency" id="currency" />
<input type="submit" value="Check" onclick="validate();" />
</body>
</html>

In general currency is in form of 0.00.You can easily validate your currency format by using regular expression.

Your pattern is like /^\d+(?:.\d{0,2})$/ .
Here /../(forward slashes) is used to quote your regular expression.
^ shows beginning of string.
\d is for any digit 0-9.
(?:) is used for not numbered value.
. is used for period.
\d{0,2} having sequence of digits between 0 to 2 places.
$ is used for ending the string.
Test() method takes one argument and check that to the pattern.
