OnEditFormValidate

This event occurs before submitting an edit form. It allows you to detect errors on the client before the form is submitted to the server to avoid the round trip of information necessary for server-side validation.

 

Signature:

function OnEditFormValidate (fieldValues, errorInfo)

 

Parameters:

fieldValues

An associative array of values containing the user input.

errorInfo

An object that provides interface (the SetMessage method) to set a validation error message.

 

Example 1:

To validate the 'percents' value and show a warning message in case of erroneous input, use the following code:

 

if (fieldValues['percents'] < 0 || fieldValues['percents'] > 100)

{

    errorInfo.SetMessage('Percent value should be between 0 and 100.'); 

    return false;

}

 

Example 2:

The following code is used in the NBA demo project to ensure that home and away teams are different for an edited game:

 

if (fieldValues['home_team_id'] == fieldValues['away_team_id'])

{

  errorInfo.SetMessage('"Home" and "Away" must be different');

  return false;

}
