In that case, the previous value of the field is restored, and the user has to enter the data again.This is not always desired (for more complicated data, it will probably be much easier to take a look, correct that one typo and continue with the rest of the form), so my preference is actually to mark the field so that the user knows which field needs to be corrected, and have the validation script not report a validation error back to the field: Using this method has implications on the form submission process: The form no longer can verify that the data is correct, so the submission function needs to do another round of validation to see if any of the required fields are not correct (one way to do that is to test all relevant fields to see if the text color is using the error color, or we can use global variables to store the validation state).
If you do not want to include the titles when you generate envelope labels from the list, you can use a regular expression to remove the titles, as the following example illustrates.
Your user interface should take care of the formatting problem by having a clear documentation on the format and/or split the phone into parts (area, exchange, number) and/or have an entry mask.
The following expression is pretty lenient on the format and should accept 999-999-9999, 9999999999, (999) 999-9999.
In the latter case, we set rc to false, and also display an error message.
When you play around with the function, you’ll notice that the validation function is only called when the focus leaves the field, so you have to click outside of the field to actually make that error message pop up.
Consult this page for more details on this problem. For the actual date validity, you should rely on another language.
The following expressions will validate the number of days in a month but will NOT handle leap year validation; hence february can have 29 days every year, but not more. A SIN should also be validated by computing the checksum digit.
To start, we create a text field and bring up the properties dialog for the field.
Then we select the “Validate” tab to see the validation options: The default is that the field will not get validated.
For numeric fields, there is a convenient way to validate a value range, but we want to select to run a custom validation script.
After the “Edit” button is clicked, a new window will open that allows us to edit the new script: This script also includes a check for an empty string, so that the user can wipe out a wrong string and start from scratch.
As I mentioned before, information is passed to the validation function in the event object, and in the code we see that the member ‘value’ is used to communicate the current value of the field.
