Is there a reason I can't get JPEGS to load on an HTML page with a bit depth of 8? Is there a workaround for this?

does anyone know how to use the "setAttribute" method in javascript to add an event to an element?
for some reason it seems that it's actually adding the event, however the event never get's fired.
here is a copy of the code I'm using:
<br />
<script><br />
var newField = document.createElement("INPUT");<br />
newField.type = 'file';<br />
newField.id = 1;<br />
newField.setAttribute("onChange","alert('hi')");<br />
<br />
document.getElementById(fields-1).insertAdjacentElement("afterEnd",newField)<br />
</script><br />
when I use the "view partial source" add-in for "ie" it shows that the element was added with the attribute, however, when I change the content of the field the event does not get fired. - as opposed to when I set that same attribute in plain HTML... - like so <input type="file" onchange="alert('hi');" id="1">
all help is appreciated.
thanks in advance,

"attribute" != "event"
If you want to add an event handler, you have to use either the inline HTML attribute that matches up to the name (this is not a normal attribute), or use either one of the scripting ways below:
myElem.oneventname = eventhandler;
myElem.attachEvent("oneventname", eventhandler);Notice the use of quotes above. Where I use eventhandler you just use the function name without quotes. This results in a function pointer. You should take a look at the "Web Development"->"HTML and Dynamic HTML" section of the MSDN Library[^] for further details.

I tried this before it did not work, - myElem.oneventname had the same results as myElem.setAttribute (obviously replaced by the element name and event type)
however, in regard to "attachEvent" - this did not even make it to where the other 2 did. - meaning, if I looked at the code (in view partial source) with the other 2 I would actually see that the event handler was in place, however not when I used the "attachEvent" function.
- I will try again though
although I still believe this is an issue thanks alot for your help, I really appreciate it.

You can't add "alert('hi')" - it MUST be a function name (without quotes). Underneath it all, this all comes down to COM implementations. attachEvent takes a string that identifies the event name and a VARIANT that is a function pointer - NOT a string. There is no magic involved here and you must follow symantecs. Instead, try somthing like this:
<script language="javascript">
function sayHi()
{
alert("Hi!");
}
myElem.onclick = sayHi;
myElem.attachEvent("onclick", sayHi);
</script>When you use setAttribute, you might thing that this would work from an HTML standpoint, but this isn't manipulating the HTML - it's creating an HTML element in the HTML Document Object Model (DOM) that would've otherwise been read by MSHTML from the HTML document. Instead, you must attach the event handler correctly. Again, the event is not an attribute though it can be represented by an attribute. MSHTML will know better and will hookup a function (or create on in memory that wraps the code you put in the HTML attribute) when it reads the HTML attributes on the element.

thanks alot, did not have a chance to test yet, but makes sense.
is there a way I can also pass a parameter with the function? (not in quotes)
I do have a way around it if not, but it's easier if I can.
thanks,

No you can't, since it's a function pointer. The caller is responsible for passing any arguments to your functions, so the function signature should match what the event has documented.

Actually, you can if you use an intermediate function:
myElement.attachEvent("onclick", function(eventData)
{
if (!eventData) eventData = window.event;
element_OnClick(myElement, eventData);
});

Hello Everyone,
I wanted to know your view point on the current discussions we are having.
We want to launch a web site for our company. What should be the design parameters of it?
Do u think that in this present times of flashy fashion, some catchy flash orieted site is a dire requirement or the good old lots-of-information kinda sites are still good?
Thanks in advance....

It all depends on the kind of website you are looking for. If yours is a 'content based' site then it wont be of necessary to go for a flashy site.
If yours is a 'revenue model' site, you should go for something to increase visitors for the site.
So, make a decession on what you are going to put on the site!!

IMHO it goes like this...
Everything thats know to catch someones attention should be used.
If you offer only copious amounts of content and a not so plesant interface or nice flash intro or banners or whatever...SOMEONE ELSE WILL!!!
I used to think that windows apps should ONLY be fully functional and never bothered with interface design or cool niceties...
Ever played with Window washer and then History Kill?
Windows washer has it all...powerful, easy to use, looks super cool...it's simply the stuff good apps are made of...
Just my opinion

It depends on your audience, your image, and the purpose of site.
Personally, I click 'Skip Intro' whenever possible on any site that has a flash intro. I think they are useless, and come between me and whatever it is I'm trying to do. If you must have one, keep it short (3-5 sec.).
The organization of your site is more important than how cool it looks, IMO. Having said that, a graphically pleasing site it always a good idea, as long as you don't sacrifice too much in terms of usability.
So, once you have the organization(conetent and navigation) of your site laid out, then you can decide on how you want it to look. What image do you want to portray? This may cause a need for fancier graphics or even some flash, I suppose. The point is there is a balance that will work for your case.

I totally agree to your opinion...
This is the most profesional way to go...
There are good and bad flashy web sites and there are good and bad content based web sites... There are also good and bad websites that are a bit of both...
You need to find the balance depending on what your target group is and what the image of your comapny is. I wouldnt take seriously a financial companys web site if it was too flashy and it would be boring to have content based and serious web site for a company that make computer games...

There is no site there at the moment, I just get IE's page not found page - that's in Verdana 
If you meant auh.edu, there is a "american western" text style flash animation, but it may not be a font, just some bitmaps - I don't recognise it. Why not ask their web master?

Actually I was asking about the font in the 'flash' animation. Anyway, I was able to 'find' the font. Thanks to 'fonts.com'.

Hi,
I have an HTML doc, and nested inside it is another doc in an iframe. In the inner doc, I have some script and need some way of getting a reference to the javascript objects of the outer doc - I plan to use this to get a copy of the outer doc's html in string. But, I can modify the outer doc at all. Is it possible?

You can access HTML elements and FORM elements as well as JavaScript Variables from within the IFRAME.
Can reference to them by using the top. keyword or the parent. I think...
E.g.
If you have a javascript variable in the main doc as such:
var myVar;
Then you can access this from within the IFRAME as such:
top.myVar
Hope this helps ...

 I select a picture (or text) on a HTML page.How do I get the HTML source code of the selected objects.Is it possible???
|
|
|
|

I haven't ever done this but there is an event which you can use. Its the :
onselectstart
event that is supported by IE for sure but I dont know if NS or Opera supports it.
Once you capture the event passing the object that triggerred the event you should be able to use the some of the following properties t get the relavent HTML code:
innerHTML,
outerHTML,
outerTEXT,
outerTEXT
Hope this helps
