XForms Basics - Welcome to Nowhere (Page 5 of 6 )
The previous example demonstrated two of the form controls available in XForms. However, there are lots more. Here's a brief list:
- <xforms:input>
A single-line text entry field.
- <xforms:secret>
A single-line text entry field which masks user input, good for passwords.
- <xforms:select>
A list field allowing multiple selection.
- <xforms:select1>
A list field allowing selection of only a single item from the list.
- <xforms:textarea>
A multi-line text entry field
- <xforms:upload>
A file upload field.
- <xforms:range>
A field which restricts entry to a range of values.
- <xforms:submit>
A form submission field.
- <xforms:output>
A field for displaying values from the instance data.
In addition, the XForms specification also defines the following elements which may be attached to the controls above:
- <xforms:label>
Descriptive information for the corresponding control.
- <xforms:help>
Help information for the corresponding control.
- <xforms:hint>
Brief usage information for the corresponding control.
Here's an example demonstrating some of them in action:
