PUBLIC:EVENT Element

Internet Development Index

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:
oEventObject that specifies the event object containing context information.

Element Information

Parent elementsPUBLIC:COMPONENT
Child elements None
Minimum availabilityInternet 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.
