Can someone explain ( with small words and crayons, where possible) the javascript timeout function ?

Let`s say , for instance, you have a mouseover image you want to display, and then go away whether the mouse moves out, or not.

Also, is it possible to prevent the cursor change on a hot spot ?

bob, setTimeout is just a function that evaluates expression after a number of milliseconds.

<script>
//this will say hello world in 5 secs
timeoutref = setTimeOut("alert('hello world')", 5000)
</script>

hotspot = image map/<area> ?

So all you need to do would be to create a function for the mouseover event, and include a setTimeout(remove_rollover(),500) line with however long you want the image to stay before switching.

As for not having the cursor change over hotspots, the closing thing I can think of is briggl's hidden links tut over at Gurus.

Or flash.

[edit]
Heh, forgot about pugzly's cursor tut. You might find what you're looking for there

Too keep the cursor from changing over a link, put cursor:default; in the style sheet for the anchor element with the link.

Thanks.
Being nearly js illiterate, I`ll go play with it, and let you know if I can make it work.

Ok, I played , I fiddled, I don`t get it.
I`m obviously missing something simple. Max keeps giving me a *does not support this action* message.

You have:
setTimeout = ("remove_rollover()",750);


it should be :

setTimeout("remove_rollover()",1000);

(setTimeout() is a function)

or

someVariable = setTimeout("remove_rollover()",1000);

the only reason I know of for assigning the function to a variable is so you can cancel it, with:

clearTimeout(someVariable);

this is more usefull with:

someVariable = setInterval("myFunction()",2000);

this repeats myFunction() every 2 seconds, until someVariable is cleared.

Will pastels do ?

Yes, hew the pastels will be fine. But too many colors at once will just confuse me again.

Also, changing the timeout line as you suggested moves the error message to *line 1 char1 object expected.*
I can`t seem to log on to my server, just now, so I haven`t updated the test page online, but that`s what` it`s telling me here.

Thats becuase in the line:
setTimeout("remove_rollover()",750);
there is no function called

remover_rollover()

so did you want to turn it off again ?
this should do it:

setTimeout("imgOff('"+imgName+"')",750);

take care with the quotation marks .. there all needed.

Sorry, Hew. I`m kinda stupid, but I`m still missing something. With the setTimeout line changed as suggested, the rollover doesn`t work at all.

Also, not sure what you mean by * so did you want to turn it off again ?* Turn what off again ? the function or the image ?

All I want it to do is display the rollover and then revert to the original image..

In the end, I want to apply this to a multiple rollover image of clouds, like lightning flashes.

When I said turn it off again , I meant to turn the image "off" again, seeing as though your function was called imgOff or something.

I made those changes before replying to see if it worked , and it did. Once the mouse was over the image, it changed until 0.75 of a second.

This worked for me:

<HTML>
<HEAD>
<TITLE>Time Out Test</TITLE>
<META NAME="GENERATOR" CONTENT="MAX's HTML Beauty++ ME">
<script language="javascript">
<!--
if (document.images) { // Active Images
img1on = new Image();
img1on.src = "testO.gif";

img1off = new Image();
img1off.src = "test.gif";
}



function imgOn(imgName) {
if (document.images) {
document[imgName].src = eval(imgName + "on.src");
setTimeout("imgOff('"+imgName+"')",750);
}
}


function imgOff(imgName) {
if (document.images) {
document[imgName].src = eval(imgName + "off.src");
}
}
</script>
</HEAD>

<BODY bgcolor="#999999">

<TABLE BORDER="1" width="50" height="50" ALIGN="center" CELLSPACING="0" CELLPADDING="0">

thanks, Hew, for the extra effort. I talked it over with a friend on ICQ, and got it worked out.
His solution was a bit different than yours, but I think I got it now. All`s well that times out well.
I`ll post the page so you can see it work, when I get it done. Little short on time, may take a day or two.

Thanks again.

Coolness, the flashes feel really "real" now, cool! What next for this domain, it's going to grow, right? (I thought I was the only one who bought domains to make one-page websites, heh. ;-) Congrats DB, we'll make a javascript monkey out of you yet!

You're missing some single quotes in the third and forth lnes of flashB1, before "m3". It's causing an error so I can't see it =/

Yea, Doc It`ll grow , prolly slow. But sure. Thanks again.
Thanks, bugs.
Max`s beauty tells me there`s an error in line 1 character 13. Line 1 has only 6 characters, so I guess its the missing quotes are the culprit, eh ? Thanks slime. I coulda looked for those for weeks.

One other silly question. In NN6.2, it works great as long as the table has a border. Set the border to 0 , and it times out before it loads the image. Is this just one of those Netscape things ?

Yeah, when it says there's an error at line one, it really means that there's an error either inside something like onmouseover="..." or onload="...", or there's an error in a setTimeout() or setInterval(). It might also do that with eval() errors. That's because these are pieces of code that the browser doesn't consider to be in the source of the page; it considers it to be off in it's own little domain, sort of.
