detachEvent method

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

Syntax

object.detachEvent(event, function)

Parameters

event [in]

Type: String

String that specifies any of the standard DHTML Events.

function [in]

Type: object

Specifies the function previously set using the attachEvent method.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.

Standards information

There are no standards that apply here.

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 PUBLIC:ATTACH element automatically stop receiving notifications when the behavior detaches from the element, and thus do not need to call the detachEvent method.

Examples

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

Code example: http://samples.msdn.microsoft.com/workshop/samples/components/htc/refs/ondetach.htm


<public:attach event="ondetach" onevent="cleanup()" />
<script type="text/javascript">
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>
