right javascript syntax

korund · Apr 3, 2006

What is correct syntax for the following scenario: show five alerts,
one by one(text different), when page loads in browser -on body onload:

alert(text 1)
alert(text 2)
alert(text 3)
alert(text 4)
alert(text 5),

then code

var iCounter=0;while(true)window.open('http://www.google.com')}};"...

how it need be in html page?

Umm ... why would you want to open a billion of windows to
www.google.com ?

korund · Apr 3, 2006

so I asked for correct syntax - there should be 2 google window, not a
billion, however.

Thanks. Is there any difference to fire code via window.onload = init;
located inside <head> tags, or via <body onload="init();"> ? What from
methods will call code faster?
The page will contain image, that need be loaded.

The Reason I asked is cause, if you intented to open a billion windows
(like the code suggested), you would not have been helped. Atleast not
by me.

Shouldn't be any difference, both basically tells the client to run the
function when the page is finnished loaded (all imageas and whatnot).

It all depends on where you want the code, that runs the function, to
be.

Hmm,

<body onload="init();"> - this will tell client run script when the
page is finished loaded, but window.onload = init; inside <head> will
cause run script immediately?

No. The post to which your message headers claim you are responding, but
which you entirely fail to quote ...

.... is quite clear that they have the same effect as far as timing is
concerned.

No. Both are subject to popup blockers.

The code will be executed at the same
speed, at approximately the same time.

The page will contain image, that need be loaded.

The UA will load them already.

As parenthesis suggest in the latter variant, you can send arguments to
your function.
In the reality it is an anonymous function calling init() function.
Internally it is:
<body onload="function anonymous(event){ init(); }">
So if you need to supply arguments in the conventional way, intrinsic
handler like <body onload="init();"> is more convenient.

There are also suggestions, which I didn't check through for all
browsers, that intrinsic handler has priority over in-code handlers,
thus between
....
window.onload = doThis;
....
<body onload="doThat();">
....
doThat will be called first no matter what. As I said I did not verify
this.

Otherwise it is probably better to keep JavaScript code by itself and
HTML markup by itself.

There is no productivity impact in neither case.

Actually, there is a difference. The first is proprietary,
the second is not. But that does not matter here

Amplifications: it seems, javascript alerts have more high priority
than popup pages(windows), since first is usually shown without
problems, but second are blocked by built-in MSIE popup blocker.

Popup adverts are common and annoying.

Alertbox adverts are rare (and not that useful to advertisers as they can't
have pretty graphics or links in them).

It is adverts that users typically want to block, so browsers deliver
features to try to meet that want.

IE is not the only browser around, nor is IE6 SP2's popup blocker the
only popup blocker around.

Not clear. I need all my javascript alerts MUST be shown for user. MSIE
popup blocker or other wind services should not disable it.

Therefore, you should not use alert() messages in event listeners for the
`load' event. And what about users without client-side script support?
