Return Type

String

Syntax

Move ( ConvertFromClient(eDataType, sValue) to ReturnedValue )

Parameters

  • eDataType: Must be passed to inform this function how to interpret the passed value sValue. This should be one of the Web Framework data type constants: typeASCII, typeNumber, typeDate, typeDateTime.

  • sValue: The value to be converted.

  • ReturnedValue: The converted value (as a String).

What it Does

This function converts a typed value from the generic format appropriate for transfer (e.g., as XML or JSON data) to the DataFlex format for that type.

For example, a date value should be converted from XML transport format for dates. For instance:

  • European format: "2013-03-24" is converted into "24/03/2013"
  • USA format: "2013-03-24" is converted into "03/24/2013"

This function is intended to be used when receiving numeric or date values from the client during an AJAX call in a Web Framework application.

This function is already used internally by the framework to convert psValue Web Properties.
