The default HTML for the Validation Text Field widget, usually inside of a form, comprises a container <span> tag

that surrounds the <input> tag of the text field. The HTML for the Validation Text Field widget also includes script

tags in the head of the document and after the widget’s HTML markup.

For a more comprehensive explanation of how the Validation Text Field widget works, including a full anatomy of

the Validation Text Field widget’s code, see www.adobe.com/go/learn_dw_sprytextfield.

Insert the Validation Text Field widget

1 Select Insert > Spry > Spry Validation Text Field.

2 Complete the Input Tag Accessibility Attributes dialog box and click OK.

Note: You can also insert a Validation Text Field widget by using the Spry category in the Insert bar.

Specify a validation type and format

You can specify different validation types for the Validation Text Field widget. For example, you can specify a credit

card validation type if the text field will receive credit card numbers.

1 Select a Validation Text Field widget in the Document window.

2 In the Property inspector (Window > Properties), select a validation type from the Type menu.

3 If applicable, select a format from the Format pop-up menu.

Most validation types cause the text field to expect a standard format. For example, if you apply the integer validation

type to a text field, the widget won’t validate unless the user has entered numbers in the text field. Some validation

types, however, let you choose the kind of format your text field will accept. The following table lists validation types

and formats that are available through the Property inspector:

Validation type Format

None No particular format required.

Integer Text field accepts numbers only.

Email Text field accepts e-mail addresses that contain @ and a

period (.) that is both preceded and followed by at least

one letter.

Date Formats vary. Make your selection from the Format pop-

up menu of the Property inspector.

Time Formats vary. Make your selection from the Format pop-

up menu of the Property inspector. (“tt” stands for

am/pm format; “t” stands for a/p format.)

Credit Card Formats vary. Make your selection from the Format pop-

up menu of the Property inspector. You can choose to

accept all credit cards, or specify a particular kind of

credit card (MasterCard, Visa, etc.). The text field does not

accept spaces in credit card numbers, i.e. 4321 3456 4567

4567.
