Text
Fields
Text items are the most basic and most commonly
used items in HTML DB. They are the item used for entry and display
of values to and from the user. There have been many examples of text
items already in this chapter, for example, the First Name and Last
Name items of Figure 10.33 are text items.
A Text field is used for the normal data entry
from the user. It will accept any characters typed into it and will
save the value to the session state when the page is submitted. The
values then can be inserted into the database or used in any other
fashion during processing. There can be up to a maximum of 30,000
characters entered into a text field.
There are a few different types of Text items:
-
: This type renders as a text field. The value entered
into the text field will be saved in the session state when the page
is submitted.
-
:
This type of text field is read only. The user will not be able to
type into the field. It will display the value of the item in a
subdued color, grayed out. The value will not be saved to the
session state upon page submission.
-
: This type of text field is much like
the Text Field (Disabled, does not save state) but as the name
implies, it does save the value to the session state upon page
submission. The value display will be more normal.
-
: This type is the
same as the normal text field. The distinction is that if the Enter
button is pressed on the keyboard, the page will automatically
submit. This is a good option to use if the goal is to let the user
have quick data entry while keeping their hands on the keyboard
instead of having to click a button with the mouse.
- :
This is another specialized version of the text field. This field
is like a normal text field, but it will have a small calculator
icon next to the field. When the icon is clicked, a calculator will
popup. The user can use the calculator to compute a value. When
Done, the value will be copied into the field. Figure 10.34 shows
the field with the calculator popup.
