Form Fields

A Form Field is the element inside a PDF that stores data entered manually by the user or dynamically through JavaScript. In Revu eXtreme®, all fields are customizable, allowing changes to the appearance as well as extending their behavior through JavaScript field events. Most fields may have their contents validate and input formats enforced. In many ways, the form fields behave very much like HTML forms.

Fields are identified by their name. Multiple form fields of the same type can have the same name. When the fields are named identically, the two fields are synchronized such that changes made to one cascade to the other. Two different types of form fields cannot have the same name.

ClosedText Box

A Text Box is used to store text, dates, numeric values, email addresses, and so on. In most cases, a Text Box is the primary way of entering raw data for a user. The data in a Text box is represented as a string or number. Additional JavaScript processing may be done to convert the text values to Date or Boolean values.

ClosedRadio Button

A Radio Button is used to indicate a choice between options. By default, Radio Buttons are in a state where nothing from the group is selected. When one of the options is selected, the Radio Button groups enters a state where at least one of the options is always selected.

ClosedCheck Box

A Check Box is used to select an option. The check box may be toggled on or off.

ClosedList Box

A List Box is used to select one or more items from a list. Once the items are selected, additional processing on the items may be performed using JavaScript.

ClosedDropdown

A Dropdown is used to select from one of many items. This option may also allow the user to specify a new option not in the list.

ClosedButton

A Button is used to invoke a calculation, sequence of events, validation of fields, generation of data, and so on.

ClosedDigital Signature

A Digital Signature is used to securely and digitally sign the document. Essentially, a Digital Signature can be used to verify if a document has been signed by the authorized person.

There are some caveats to using a Digital Signature: mainly, once the contents of the document have been digitally signed, any modifications to the document will render that signature invalid. Also certificates must be distributed to others who want to verify that documents are coming from authorized people.
