Inline events

  • Explorer 3 on Mac doesn't support events at all.
  • My test page doesn't yet work in Konqueror, so I can't yet offer Konqueror info.

    •  

    This is the compatibility table for inline events, that is, events that are handled inside a tag.

    Examples:

    <A HREF="#" onMouseOver="omo()">
<TEXTAREA onKeyUp="checkItAll()">
<P onDblClick="anotherFunction()">

    Notes:

    EventHTML Element NN2IE3Op3NN3Op4Op5NN4IE4IE5NN6iCabWebTV
    Abort On <IMG> NoYesNo YesNo
    Blur
    Focus    		On form fields Partial
    (Blur: Only for NN2 Mac)    		 Yes
    (Mac: Partial)    		 PartialYes

    On <BODY> NoYes
    (Mac: No)    		 NoYes
    (Mac: No except for iCab)    		 Impossible
    Note for Netscape 6: The good old onBlur="self.focus()" in a popup crashes my Netscape 6.01 horribly, while the reverse onFocus="self.blur()" does nothing.

    if you notice a mistake in this table, please tell me.

    onError

    Few people will know that the onError event handler also exists for an <IMG>. When you do

    <IMG SRC="whatever.gif" onError="doSomething()">

    the script doSomething() is executed if whatever.gif (the SRC) is not found on the server. This can sometimes be very useful.

    Even more to my surprise, Netscape 4 on Linux and Netscape 6 allow an onError event handler on the BODY tag, firing whenever a JavaScript error occurs.
