detachEvent Method

Unbinds the specified function from the event, so that the function stops receiving notifications when the event fires on the object.

Syntax

object.detachEvent (sEvent, fpNotify)

Parameters

sEvent Required. String that specifies any of the standard DHTML events.

fpNotify Required. Pointer that specifies the function previously set using the attachEvent method.

Return Value

No return value.

Remarks

Behaviors that attach to events using the attachEvent method must explicitly call the detachEvent method to stop receiving notifications from the page when the ondetach event fires. Behaviors that attach to events using the ATTACH element automatically stop receiving notifications when the behavior detaches from the element, and thus do not need to call the detachEvent method.

Example

This example calls the detachEvent method from an HTML Component (HTC) when the highlighting effect is removed from the page, causing the ondetach event to fire.

Sample Code
<PUBLIC:ATTACH EVENT="ondetach" ONEVENT="cleanup()" />

<SCRIPT LANGUAGE="JScript">
attachEvent ('onmouseover', Hilite);
attachEvent ('onmouseout', Restore);

function cleanup()
{
   detachEvent ('onmouseover', Hilite);
   detachEvent ('onmouseout', Restore);
}

function Hilite()
{
   if (event.srcElement == element)
   { 
     normalColor = style.color;  
     runtimeStyle.color  = "red";
     runtimeStyle.cursor = "hand";
   }
}

function Restore()
{
   if (event.srcElement == element)
   {
      runtimeStyle.color  = normalColor;
      runtimeStyle.cursor = "";
   }
}
</SCRIPT>
