i bring up a simple lines for polo, so that he would be able adapt all the lines easily. But since you also need it, then i will provide a new example later.

Good day...

Hi,

Well, not really!

Why not try something efficient, readable and crossbrowser compatible like:

--------------------------- 8< ----------------------------
<body>
<div>
 <ul id="demo" style="width : 180px;">
  <li><a href="#">Sample Link 1</a></li>
  <li><a href="#">Sample Link 2</a></li>
  <li><a href="#">Sample Link 3</a></li>
  <li><a href="#">Sample Link 4</a></li>
  <li><a href="#">Sample Link 5</a></li>
 </ul>
</div>

<script type="text/javascript">
document.initMenu = function(id){
  var menulist = document.getElementById(id).getElementsByTagName("li")
 for (var i=0; i<menulist.length; i++){ 
      menulist[i].onmouseover = function(){this.className='onHover'} 
      menulist[i].onmouseout = function(){this.className=''} } }

document.initMenu("demo")
</script>
</body>
</html>

and cut the 1.51KB long script short, to 300bytes of working code instead?

Hi troyIII,

As you can see, in my sample-code there's an un-paired <div> tag over at line#99. And might be causing a bit of a problem over the document. The script also provides another cross-browser addEvent( param1, param2, param_N ) handler functionality -- that allows you to add events' on a shorter range of call.

You are complaining about 1.51k size, without thinking that it is the overall size of the entire document and not just by the script itself.

A standard valid document would atleast cost you 0.908b for its total file size under Strict markup:

- and would you mind showing me some sample code using your script above, if the target is on the <a> and not just from a normal <li> tag execution?

Lets see how long you can hold those lines without repeating the call over the <li> tag and change its background with an <anchor> call...

If i had another <li><a href="#" onmouseover="somefunc();" onmouseover handler inside my anchor, then this will complicate things with the code you have provided.

I think you should read this A R T I C L E about event order.

Hey Ess, it that a new avatar?

Airshow

hi Airshow,

ive just uploaded it lastweek. Have you tried the last code that i've posted here? About the hover stuff? I can't seem to detect it, if it has a line problem. When it is working 99.9% in OPERA. Can you give it a go and see how things working over the console.log.

Thanks...

Hi Ess, I'm dead on my feet here. Must get some sleep now.

I'll be happy to give it a go in the morning.

Best wishes

yeah, that's one of the hardest part, when i am working with codes on a handheld device.

:) you must be exhausted from work.
Sleep wel and see you at the forum later...

I'm not sure I understand what are you arguing about at all. <li><a href="#" onmouseover="somefunc();"> will not break anything!

1. I'm pretty sure that someone - better skilled with CSS - could achieve this 'hover effect' without javascript at all.

2. Imagine every required simple-task-script to be taking each time more than 1.50KB

3. sorry but a standard "valid" document will not cost more than this: (less than 500bytes)

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<head>
<title>Title</title>
<meta http-equiv="content-type" content="text/html;charset=utf-8">
<style type="text/css">
</style>
</head>
<body>
<script type="text/javascript">
</script>
</body>
</html>

4. I don't think that code I provided would come into complicated situation at all:

5. and to prove it to your self, you can try this complicated and not allowed nesting you suggested also:

<ul id="demo" style="width : 180px;">
 <a href="#"><li>Sample Link 1</li></a>
 <a href="#"><li><a href="#">Sample Link 2</a></li></a>
 <li><a href="#">Sample Link 3</a></li>
 <li><a href="#">Sample Link 4</a></li>
 <li><a href="#">Sample Link 5</a></li>
</ul>

Your proposed nesting will not validate, because you can't have an inline element containe in a block element. Although the script functionality will not break, except for css at the first Li (in IE).

And here we can make the previous script I wrote for this ocasion, more generic and of universal use with just a few changes while still keeping it below (400 bytes) of weight:

<script type="text/javascript">
document.hoverElementsBy = function(id, tag, cls){
  var coll = document.getElementById(id).getElementsByTagName(tag)
 for (var i=0; i<coll.length; i++){ 
      coll[i].onmouseover = function(){this.className=cls} 
      coll[i].onmouseout = function(){this.className=""} } }

document.hoverElementsBy("demo", "li", "onHover")
</script>

* Usage:
* document.hoverElementsBy([parentID], [targetedTagName], [classNameToApply])

With this cript encapsulated you can now target any container element; chose any explicit tags contained to recieve the behaviour; and apply any style you've defined in class css selector at your style element.

Simply calling:
document.hoverElementsBy("rightNav", "div", "hoverClass") or similar.

Oh that is even worst, than i thought!A 500bytes, in size, that is of course if you are using the standard HTML 4 markup, and no extra <meta-data> included, but not with the XHTML markup.And also this is the worst example i've ever seen and not even on a book or in any website would show example of wrong pattern like this one you created:

<ul id="demo" style="width : 180px;"> <a href="#"><li>Sample Link 1</li></a>

even the new comer, would not attempt such silly nesting pattern on their document. - so don't make me stupid, than you are right now!!! And here's the document that will show you, about the things that im trying to point out. So give a test before you butt in again...

It is you who argued that my code will break in case somebody tries to use some sort of wrong nesting or even a MOUSEOVER event on a nested LI element.

But that super-short script of mine, factuated to bee buletproof even in a badass html structure situations.

So what is your problem than!
I really don't know what you are "chating" about?
Your redoundant code is still not working on my Explorer.

You take my correct [last example] code from the previous post AND test it against any capable browser and handheld devices including your nokia running on Opera v.86.5. AND TEST IT. -Because I don't have one!

Than come back complaining to me, but meanwhile we could use some working code instead.

And please don't come back to argue about CSS if it's not displying properly because I used the one you supplied here, and I'm not to blame if that verison of opera you have is not capable to render exactly as you stated in your CSS. [ the only change I made is that removed indent you gave to hover-class] 'cause anyway we are talking JavaScript here.

And please don't point me to PPK's pages cause I've known him since his very first beginnings on javascript.

Try to read the post and see if you can find any word's saying that your code will break!? What i said, is that it will complicate things when you accessed the child within their collection, on various situation if they have another attached event! Redundant code? Which part of the code are you claiming? I can even provide you a shorter stance of that code of yours, so what are you trying to prove then?
That you had a better lines?

Then who cares?

If you think you've got better solution, then post it and stop complaining...

My script was not accessing children inside the collection - it was accessing a filtered collection of exact elements explicitly from the container specified.

And in case you later need to manipulate their children or parents; adding: return coll at the end of the function would provide you with ready to use collection any time you need to further manipulate parents or their children.
Or you could do it inside the function directly.
for instance: coll[i].parentNode.onmouseover= ... And the call: document.hoverElementsBy("demo", "li", "onHover") can be used anyway you like adn on any existing tag element on any container with an ID:
document.hoverElementsBy("demo", "a", "onHover")
or even
document.hoverElementsBy("demo2", "div", "backgroundNew")
or
document.hoverElementsBy("demo", "b", "adborder")
etc etc...

But that was not my point...
I allready told you that: http://www.daniweb.com/forums/post932988.html#post932988

I was hoping that you will get my point yourself and I was pretty sure you'll get to this conclusion by now without me having to point it out:

There is nothing more compatible than DOM Level NULL, - that is: DHTML!

A coder with a damn experience will develop his code from its roots, not the other way around. And will begin to implement new level extensions only when absolutely necessary.

I will never even open a <script type="text/javascript"> tag, before I really need it.

It is not our duty to support future browsers, it's the other way around - future browsers are, should and will be required to support their previous versions.

And an experienced coder will embrace only the methods that will give him extended functionality and controll but will only use those that will degrade gracefuly in prevoius browsers and in exchange offer him some advanced controll over his contents in browsers that support those commands.

But who cares when you have such a bad temper...
Anyway thanks for your repply.

Anyway thanks for your repply.

Whew, I love a happy ending :* ... and just when I thought we might be getting into a fight.

I think you guys have got to agree to differ - which is cool.

Ess I overslept this morning and must get away to work now. There's so much code and discussion above I would need two days to follow it through.

May I assume we have two really great fully working solutions here, that are completely different?

Actually this the second time, we had an argument like this. So do we have to keep it this way? I'll do what i want in my codes and and you do yours.
If you think that my code is just a piece of crap then don't bother or waste your time to run it...

Anyways if you say that my code didnt work inside your browser.

Then maybe this one will:

hi Airshow,
you're quite right, maybe i need some rest...

0

I am truly sorry to disappoint you - but it doesn't!
there's no such thing as "inherit" (line 63): onmouseout="this.style.background = 'inherit';" In some browsers it will simply assign invalid value. - that is: nothing -and the browser will be forced to use the default, but in other -it will rise an error that might interefere with other lines of code to... but not in this case.

Yet, correcting that inline code -will not help either. This code will never run on explorer even if corrected, since you will also have to correct the html structure.

0

Hmm, it seem that IE doesnt like the call.
now i get it, maybe you could try onmouseout="this.style.backgroundColor = 'inherit';" instead of a the background rule. Try it again and let me know how it worked.

0

It wuldn't do, I told you that there is no 'inherit' property either way.
Some browsers like mozillas -won't rise an error on wrong css selector asssignements through js but will silently fall back to the default selector stated in style if any.

You should use an empty string, or (in this casse) the correct className instead. Or assign some other selector but not "inherit" since there is no such thing exposed to javascript methods as far as my knowlledge.

And it's not the inlinescript the thing that is not working on IE its simply thows the error but also falls back to default and changes the color to white on hover.

What is not working is the whole function...

0

As far as i'm concerned all of those methods and properties that i have used over the last posted function are well supported in IE5.5+, so i keep wondering why still it didnt work inside your IE6-version!? parentNode, nodeName, srcElement would be enough to penetrate IE5+ mode. If that doesnt work, then don't bother wasting your time running the script.

0

'Inherit' is a 100% good cool CSS attribute. It's in the CSS2 and CSS3 recommendations - maybe CSS1?

Unfortunately (I read here) Internet Explorer 7 and earlier versions don’t support the value inherit for any properties other than direction and visibility. IE also throws an error if you try to set 'inherit' inappropriately, but it is catchable (I just tried in IE6).

If that doesnt work, then don't bother wasting your time running the script.

I don't have to run one script over and over again to understand that it isn't working. I knew that it will not work even before I tested it. "parentNode", "nodeName" etc are not the issue.

I will point you to the first major error on your function
and that's the very first line: onmouseover = onmouseout = function( e ) You find out why.


p.s.:
A Hint


Try this:

function onclick(e){//b.b. Troy III p.a.e.
        e=e||event; e=e.srcElement||e.target; e=e.nodeName;
        alert(e);
}
document.onclick = onclick;

If you execute this code in FX, you'll get the alert report twice, which is a general mozilla bug, and all the netscape broods have it; -and this bug is the only reason why your function is even triggering there.

Inherit is an internal command, doesn't need to be stated.
Properties are cascadingly inherited from the parent towards all of the children of any element. And that's the core logic of CSS.

<body>
aaaaaaaaa
<div>
bbbbbbbbb
<span>
cccccccccccc
</span>
bbbbbbbbb
</div>
aaaaaaaaa
</body>

Now, if you specify "color:red" for the body element all other elements will have that color unless overriden from its children.
Than if you state "color: blue" for the contained div a will remain red, b will become blue, but also the c. There is no logic to go state "color: inherit" for the span element for it to take the color of its parent, otherwise css would be a total waste.

Inherit should be used only for properties that are NOT inheritable by definition.

TIII,

Well at least that's a little better than ' there's no such thing as "inherit" '.

Have you read the WC3 Recommendations?
