shiftKey Property

event Properties   DHTML Events


DOM Level 2 Specification.

Retrieves the state of the SHIFT key.

Syntax

HTML N/A
Script [ bKey = ] event.shiftKey

Possible Values

false The SHIFT key is up.
true The SHIFT key is down.

The property is read-only with no default value.

Remarks

This property is used to indicate whether the SHIFT key was depressed during the firing of the event.

Example

This example tracks whether the Alt, Ctrl, or Shift key returns true ( was pressed ) when an onclick event fires. Click the button with or without any of the keys mentioned and see.

Here's the code for that exercise:

<script language="JavaScript">
<!--
function chkKey ( ) {
   var ctrlKey = document.layers ? event.modifiers &
     Event.CONTROL_MASK : event.ctrlKey;
   var altKey = document.layers ? event.modifiers &
     Event.ALT_MASK : event.altKey;
   var shiftKey = document.layers ? event.modifiers &
     Event.SHIFT_MASK : event.shiftKey;
   alert ( 'Ctrl ' + ctrlKey + ' \nAlt ' + 
     altKey + ' \nShift " + shiftKey );
}
//-->
</script>
