§ The halt Command

The halt command prevents an event from bubbling and/or performing its default action. Depending on the form you use, it may also exit the current event handler.

Here are the different forms:

• halt -- halts both bubbling and default, then exits the event handler (like exit)
• halt the event -- halts both bubbling and default, but continues execution of the handler
• halt the event's bubbling -- halts only bubbling, continues execution
• halt the event's default -- halts only the default action, continues execution
• halt bubbling -- halts only bubbling, then exits the handler
• halt default -- halts only the default action, then exits the handler

§ Examples

<script type="text/hyperscript">
  on mousedown
    halt the event -- prevent text selection...
    -- do other stuff...
  end
</script>

§ Syntax

halt [the event['s] (bubbling | default)]
halt [(bubbling | default)]
