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
Example
ssParseNum($5,000.00,true);
Will return: 5000
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>
