SsParseNum

Overview

To convert a number from a formatted string (containing symbols like "$" or "%") to a number using JavaScript you can use a function called ssParseNum.

ssParseNum is preferred to the standard parseFloat function because it automatically replaces the dollar sign.

Syntax

ssParseNum( value, emptyok );

Where:
value - is the a value to be converted to a number (i.e: $5,000.00 and 5,000% will be converted to 5000)
emptyok - is a true/false value

• if emptyok is true - an empty string will be returned by ssParseNum if the value is empty
• if emptyok is false - a "0" will be returned by ssParseNum if the value is empty

Examples

ssParseNum($5,000.00,true);

Will return: 5000

---

If you wish to display a ratio of two fields that are set to have currency formatting, you should convert the values to numbers using ssParseNum:

ssParseNum(field1,true)/ssParseNum(field2,true)

Requirements

This function is part of the sstools.js library and needs to be added to Browser Script custom fields or on template pages, sign-up pages etc. using the following syntax:

<SCRIPT type="text/javascript" language="javascript" src="/sstools.js"></SCRIPT>
