Description
ColdFusion generates JavaScript or ActionScript
to directly control the data a user enters by
specifying a pattern. For example, 999-999-9999
requires a user to enter ten digits, and
automatically fills in the dash (-) separators to
create a formatted telephone number.
For detailed information on using masks, see
"Handling invalid data" on page 750.
In HTML and XML format, ColdFusion generates
JavaScript that runs on the browser to check
whether entered data is valid and provide
immediate feedback, if the entry is invalid.
In Flash format, uses Flash built-in validation
routines.
In HTML or XML format, the validation logic is
identical to onBlur validation, but the test is not
done until the user submits the form.
In Flash format, this validation type is identical to
onBlur Validation. Flash checks do not
differentiate between the two events for
validation.
ColdFusion checks submitted data for validity and
runs a validation error page if the data is not valid.
You can use the cferror tag to specify the
validation error page.
ColdFusion uses the same validation logic as with
onServer validation, but you must create
additional, hidden, fields and you can use this
technique with HTML tags or CFML tags.
For detailed information on using hidden fields,
see "Validating form data using hidden
page 755.
ColdFusion includes the specified JavaScript
function in the HTML page it sends to the browser,
and the browser calls it.
For detailed information on using JavaScript for
validation, see "Validating form input and
handling errors with JavaScript" on page 759.
