PUBLIC:EVENT Element

  • Artigo

Defines an event of the HTML Component (HTC) to be exposed to the containing document.

Syntax

<PUBLIC:EVENT
    ID = "sEventID"
    NAME = "sName"/>

Attributes

  • ID
    Optional. String that uniquely identifies the PUBLIC:EVENT element within the component. This attribute is analogous to the ID attribute in Dynamic HTML (DHTML).
  • NAME
    Required. String that specifies the name of the event exposed to the containing document.

Methods

  • eventID**.fire(** [oEvent] )
    Fires the event to the containing document.

    This method has the following parameter:

    oEvent Object that specifies the event object containing context information.

Element Information

Parent elements PUBLIC:COMPONENT
Child elements None
Minimum availability Internet Explorer 5
Minimum operating systems Windows 95, Windows NT 4.0

Remarks

By specifying a NAME attribute similar to a standard event already defined for the element, a behavior can override the element's default behavior.

Events defined for a behavior do not bubble; they only fire on the element to which the behavior is attached.

Examples

This example is derived from a calculator behavior sample. Whenever the result changes, the HTC fires a custom onResultChange event back to the page, passing the result as a custom property of the event object.

<PUBLIC:EVENT NAME="onResultChange" ID="rcID" />

<SCRIPT LANGUAGE="JScript">
function doCalc()
{
   :
   oEvent = createEventObject();
   oEvent.result = sResult;
   rcID.fire (oEvent);
}
<SCRIPT>

This example shows what the containing page looks like.
