This function reports the result of external field validation. If validation is reported to have failed, the field is redrawn with a thick red border and the error message provided is shown in a yellow band at the top of the form. The user is not permitted to save the record until a subsequent call to detailReportValidation() reports the field as error-free.
The detailReportValidation() function is functional only for fields registered for browser-side validation. All fields created with detail form macros are automatically registered for validation. You can register other fields with the detailSetValidateFunction().
(Required) Specifies the form element object containing the field. The easiest way to obtain this is to pass this argument to the event handler performing the validation. Another way is to use the standard JavaScript function document.getElementById().
(Required) A Boolean or integer value specifying whether the field is in error. Setting a field in error prevents the user from saving the record, causes the field to be highlighted with a thick red border, and places the error message supplied as the third argument in a yellow band at the top of the form. Setting a field as not in error reverses these changes.
A text string specifying the message to display in the yellow band at the top of the detail form when the has_error flag is set. This argument is required if has_error is set.
