XForms Properties
XForms properties define data restrictions, types and
behaviors.
XForms Properties
XForms uses properties to define restrictions (or other
attributes) that can affect the behavior of XForms controls.
Examples:
A required="true()" property will not allow the specified instance
data to be submitted as an empty value.
A type="decimal" property will only allow a decimal value to be
submitted.
A calculate property can calculate a value for the instance data.
Please refer to the properties reference at the bottom of this page.
Binding Properties To Data
XForms uses the <bind> element to bind XForms properties to XForms data:
<model>
<instance>
<person>
<fname/>
<lname/>
</person>
</instance>
<bind nodeset="person/lname" required="true()"/>
</model>
|
In the example above, the attribute nodeset="person/lname" binds the property
required="true()" to the instance data element <lname>.
