Two Onload Functions, But how?

={ Advocated }= · Sep 9, 2003

Hi there, i need to add to onload functions, well one function to an
existing one..

This is the original one:
<BODY leftMargin=0 topMargin=0
marginwidth="0" marginheight="0"
onload="MM_preloadImages('homeblack.gif','mailblack.gif','bookmarkblack.gif'
)">

And i need to add this:
<body onload="init()">

Cant seem to get it to work though?

Any ideas?

Cheers

There are no "leftMargin" topMargin" "marginwidth" or "marginheight"
attributes in HTML. They are badly supported unoffical extensions.

Use: body { margin: 0; padding: 0; } in a style sheet to do this properly.

onload="MM_preloadImages('homeblack.gif','mailblack.gif',
'bookmarkblack.gif' )">

Eugh. Macromedia JavaScript, generally regarded as "yuck".

Here's a nice preloader script:

And i need to add this:
<body onload="init()">

You can only have one onload function... but that function can do multiple
things.

onload="preload();init();"

Or, better yet (IMO) move it to an external JavaScript file:

window.onload = function() {
preload();
init();
}

There's no need at all to use leftmargin and topmargin. The browsers
that support them support the CSS equivalents as well.

marginwidth and marginheight are only needed by NN4. How important is
it to remove the body margins in a browser that probably screws up the
rest of your design anyway? ;-)

onload="MM_preloadImages('homeblack.gif','mailblack.gif','bookmarkblack.gif'
)">

Ah, Macromedia's JS functions. Sigh.

<body onload="init()">

Two ways.

1. Make a function.
onLoad="myFunc()"

and then in your JS:
function myFunc() {

MM_preloadImages('homeblack.gif','mailblack.gif','bookmarkblack.gif');
init();
}

has the advantage of being compact and can be shared between many
pages in an external JS file. Not so useful if, for example, you're
preloading different images on different pages.

2. Directly in the event handler.
onLoad="
MM_preloadImages('homeblack.gif','mailblack.gif','bookmarkblack.gif');init();"

The bit you were missing was the ; between the calls to the two
functions.

Just create a function that calls both the functions
you want to call.

function zot{
MM_preloadImages(......)
init()
}

Then call the zot function from
'onload='

Reread the section on functions in
your JavaScript reference.
