  • Event WInput :OnValidate
  • Parameters
    hEvent

  • Return value
    NIL

Special event that occurs every time a <Input> type control changes value and when the form 'submit' is performed. The event, as in the rest of the xaWeb cases, can be processed at the JavaScript level or at the CGI level:

  • If it is resolved at the JavaScript level, it will receive two parameters in the function that you have indicated: the value of the control and the HTML element. It must return a simple JSON with the 'pass' property with true or false and another 'error' property (optional) with the description of the error that occurred.

  • If it is resolved at the CGI (Harbour) level through a 'service' type operation, it will receive in its only hParam parameter the values: 'Value' and 'Id'. It must return a simple JSON with the 'pass' property with true or false and another 'error' property (optional) with the description of the error that occurred.
    • For further information consult the programming guide.
