3.6.1 Input 

elements 

 

 

Figure 9: Input element – focus is in the input box with numeric format. 

An input element specifies a text entry object for data input. It is shown as an input box in a card. The 

text entered in the input element can be determined by the format attribute. The format string 

specifies that a particular character must be a number, an uppercase character, or a lowercase 

character, for example. 

The user can enter any characters in the input field but the characters that do not currently match the 

format are drawn in red color and are underlined (so that incorrect spaces or missing characters 

become visible). In addition, every time the user enters a different type of input than the browser was 

expecting,  an  appropriate  info  message  in  an  "Incorrect  input  dialog  box"  will  be  displayed.  All 

characters that do match the format are drawn in black (normal body text color).  

The author can specify a maximum length for the entry either with the format or with the maxlength 

attribute. If the maximum length is reached, the input element will not insert any characters in the 

field, but will beep and display an info message. 

The author can specify with the emptyok attribute that the entry must match the format mask. If 

there are input elements that do have that requirement, but the entry in those elements does not 

match the mask (such as when the value is empty) and a task is initiated (either by a user action or 

timer), the Missing Input dialog box will appear. Once the user has closed the dialog box, the focus will 

move to the first of those input elements on the card. Note that the user can exit the card only if all 
input elements have a valid value or if they are allowed to be empty.
