Windows Script Components

createEventObject Method


oEvent = behavior.createEventObject()

Values

behavior

The ID of the <implements> element used to implement the Behavior interface.

Note
By default, the createEventObject method has global scope and can be accessed without referencing the Behavior handler ID. For example, instead of using Behavior.createEventObject as shown in the syntax, you can simply call the function as createEventObject. For more details, see the <implements> element.

oEvent: An event object created by the method.

Remarks

The same event object cannot be reused in multiple fireEvent calls.

Example

The following partial script component is derived from a hypothetical calculator script component. Whenever the result changes, the script component fires a custom onResultChange event back to the page, passing the result as an expando property of the event object.

Note
A CDATA section is required to make the script in the <script> element opaque. For details, see Script Component Files and XML Conformance.

	Copy Code
<component> <implements type="Behavior"> <event name="onResultChange"/> </implements> <script language="JScript"> <![CDATA[ attachEvent("onclick", doCalc); function doCalc() { // Code here to perform calculation. Results are placed into // the variable sResult. oEvent = createEventObject(); oEvent.result = sResult; fireEvent("onResultChange",oEvent); } ]]> </script> </component>

Copy Code

<component>
<implements type="Behavior">
   <event name="onResultChange"/>
</implements>
<script language="JScript">
<![CDATA[
attachEvent("onclick", doCalc);
function doCalc()
{ 
   // Code here to perform calculation. Results are placed into
   // the variable sResult.
   oEvent = createEventObject();
   oEvent.result = sResult;
   fireEvent("onResultChange",oEvent);
}
]]>
</script>
</component>

The following shows what the containing DHTML page might look like. When the onResultChange event fires, the results of the calculation are extracted from expando property result of the DHTML window.event object and displayed in the resultWindow <DIV> element.
