Validating Form Data

When a user fills in a form it can be useful to know if they filled in certain required fields. This is called "validation".

example

To Validate

1. Make your form with all the fields named

2. In the Behaviors panel, select a browser (3.0 and later).

3. In the Document window, select the form (you select from <form> to </form> in the html).

4. In the Behaviors panel, add the action Validate form.

5. In the dialog box, all your fields should be listed. Click the ones that you want validated and select from the options:

• value: required---if this is checked than the user must fill in this form or it will not be accepted.
• accept: anything, number, email address, number from...---these will make sure that the form only accepts whatever is checked.

6. Click o.k.

9. In the Behaviors panel, select the onSubmit event

*note: a dialog box will appear if they fail to meet the requirements of the form.
*note2: you can also use the onBlur event to make the form lose focus (the content disappear if it is not the right content).
