globalization.stringToNumber

Parses a number formatted as a string according to the client's user preferences and returns the corresponding number.

navigator.globalization.stringToNumber(string, successCB, errorCB, options);

Description

It returns the number to the successCB callback with a properties object as a parameter. That object should have a value property with a Number value.

If there is an error parsing the number string, then the errorCB callback is invoked with a GlobalizationError object as a parameter. The expected code for this error is GlobalizationError.PARSING_ERROR.

options.type can be 'decimal', 'percent', or 'currency'. The default options are {type:'decimal'}. The options parameter is optional.

Supported Platforms

  • Android
  • BlackBerry WebWorks (OS 5.0 and higher)
  • iPhone

Quick Example

In the case when the browser is set to the en_US locale, this should display a popup dialog with text similar to "number: 1234.56".

navigator.globalization.stringToNumber(
  '1234.56',
  function (number) {alert('number: ' + number.value + '\n');},
  function () {alert('Error getting number\n');},
  {type:'decimal'}
);
