<initial>

<initial>

In a typical mixed initiative form, the <initial> element is visited when the user is initially being prompted for form-wide information, and has not yet entered into the directed mode where each field is visited individually.

Attributes

Name	Data type	Description
name	String	The name of a form item variable used to track whether the <initial> is eligible to execute. Default is an inaccessible internal variable.
cond	String	An expression that must evaluate to true after conversion to Boolean in order for the form item to be visited.
expr	String	The initial value of the form item variable. Default is ECMAScript undefined. If initialized to a value, then the form item will not be visited unless the form item variable is cleared.

    <field name="name"/>
    <field name="age"/>
    <field name="color"/>

    <filled>
      <if cond="name=='Lassie'">
        <prompt>
          The dog's name is <value expr="name"/>.
          He is <value expr="age"/> years old.
          His fur color is <value expr="color"/>.
        </prompt>
        <elseif cond="name=='Garfield'"/>
        <prompt>
          The cat's name is <value expr="name"/>.
          He is <value expr="age"/> years old.
          His fur color is <value expr="color"/>.
        </prompt>
        <else/>
        <prompt>
          I did not understand you.
        </prompt>
      </if>
    </filled>
