Solution 1

You can use Javascript RegEx to validate for a currency input (assumption based on name of text box). A quick search of a google term to reveal that gives you;
validate-currency-amount-using-regular-expressions-in-javascript[^]

Solution 2

Using Regex
Javascript Currency Validation[^]

without Regex
Money Format[^]

BTW you may use maxlength[^] Attribute to specify the maximum length of the control.
