DHTML - replacing text in a table cell

I can give you the LONG way of doing it first, then when I figure out the better way then I will tell you that second.

The long way is to place an "onfocus" event on each element on the form. I am sure you have thought of this though, if not just ask again and I will give you the details.

Now I am off to figure out the easy way... I am sure it has something to do with bubbling but the onfocus event does not support it, also it could be done using Behaviours but I do not know how they work, yet... *opens up Homesite and MSDN.Microsoft.com*

I need to be able to replace the text in an HTML table dynamically. How can this be done with JavaScript (no ActiveX) to request a small file from the server to fill in the text area.

Happy programming!!

Use an IFRAME and just change it's source. This will only work in IE. You can however use NS LAYER to buffer the external source contents and copy into a DIV or P tag using innerHTML.

Or use IE's data binding technology using the Tabular Data Control (TDC) Data Source Object, which is really cool, but again only works in IE as far as i know

I'm looking for someone to test the WAP 'new articles' page:

http://www.codeproject.com/info/wapnew.asp

It works fine in an emulator but I've no WAP unit to actually test it with. Comments or suggestions welcome.

cheers,

Chris, when I get back to SA (3rd Feb) I can check it out on my phone. (not bothered to get a UK sim card or enable international roaming (bloody expensive))

Just remind me.

I agree on the emulator thing though. Some WAP pages we did looked great on emulators but not on the actual phones. Even some emulators made by the phone manufacturer was not perfect. Also the perspective can change things (i.e. from a PC screen to a mobile screen is very different.)

Thanks mate.

BTW - which emulator do you use? I'm using the Nokia but it's a POS. Incredibly clunky Java (when will companies learn Java is not for GUIs!) and no matter what I do it caches content so it requires a restart each time a page is changed.

Well to be frank, and ernest (in New York. umm you have to watch the movie to get that joke. think it is A Long Kiss goodnight, not sure) I have not touched WAP since about 2 months after it came out, i.e. a long time.

From what I remember the emulator I used most was Wapalizer. But as with most it is not always 100% accurate. It is like asking the W3C to validate your HTML. They will say "looks great, good job" but when you view it on IE or Netscape it is a pile of rubbish.

I got the opening page to show on my Siemens C35i, but trying to view any article resulted in "500 Internal server error" and "1001 invalid scheme in URL".

Chris Maunder10-Jan-02 22:35

10-Jan-02 22:35

a 500 error? that's odd.

The page is merely a list of articles - you can't actually peruse them via WAP (imagine trying to view a 50Kb article on a 1"x1" screen at 9600 baud. Yikes!

I just wanted to see if things were working as expected. I'm more than happy to put any information you think worthwhile onto a WAP page.

cheers,

Some things I would like to see, but they are not "must haves", just "if you have time". Smile | :)

New post in forum. Like the indicator on the forum page which shows you the # of old and new posts.

New articles in categories. Once again, just a number, or if you have more time then the first few words of each new articles title.

A simple indicator saying someone has replied to one of your posts.

Frankly there is not much useful WAP stuff out there, not because WAP is at fault but IMHO because the phone screens are so bloody small and terrible to use.

The problem with this is how do you define 'new'? The WAP specs dicate cookies - but cookies aren't always implemented, so it's back to the old 'lowest common denominator'

And where's my code snippet scripts? Huh? Huh?!

(feeling a little under pressure after asking for new features, so I'm turning defence into attack Smile | :)

and confusing the issue in order to make a quick exit stage left.)

Without a cookie the only way would be to add extra data for each member which says whether they have viewed an item or not. If viewed, not new, if not viewed, new.

However I can see your blood draining from your face as you think of your poor servers and the strain this puts on it.

The only other way then would be to have a cut-off date. Lets say two days. Anything older than two days is not new. Everything else is new.

But that severely cuts down on the usefulness of the ideas.

So get new servers? Just win the lottery! It will make you happy Wink | ;)

Blush | :O

it is amazing how things which are not "official" or do not have strict deadlines just go on and on and on and on and never get finished. Well as soon as I am back from London I am going ahead with it, and I know Jason is still keen, he is just a bit busy.

Would you prefer money or the scripts? Big Grin | :-D

Chris Maunder wrote:

Ok, as for the WAP features they were off the top of my head and I am pretty sure I actually would not use them much. WAP connections are expensive in SA (about 4 times more than a normal mobile voice phone call.) So don't even think of stressing over that.

Now that is an understatement! FiretrUCKING swamped is more like it, if I was just busy I would be relaxed by comparison. Roll eyes | :rolleyes:

I have been feeling a bit guilty about my lack of activity on the snippet project. Fortunately Chris is all the way over in Canberra and I am relatively sure he can not hit me with a beer from there. Smile | :)

Seriously though, Paul is right I am still willing and interested. As soon as Paul gets back home we will touch base and see if we can get things rolling. (one more project for the to-do list *groan* Wink | ;)

)

At least I am managing to skim the forums a bit again. I haven't been able to spare the time to do more than glance at the Lounge a few times in the last month. Dead | X|

hi,

A link has been put on the client web site.By clicking the link it opens a page in my server.I have given the below link to the client:
click
The problem is that,i want to make my site secured and give access for only registered clients.i wanna get their reference and validate in my database.I can get the clients url through server variables HTTP_REFERER,but for the clients who want to open in POP UP windows it gives problem,since HTTP_REFERER doesn't work on POP UP.I can write a javascript on the client side to capture their url but they are not willing change ant code of their side.

So,could any one help me out with this problem.I want some client details so that i can validate in my page through database.Thanks in advance!! Frown | :(

Hi Chandan.

Very quick reply here as I am just heading out the office.

We had this problem and found we had to store the refferer in a session variable (uniquely id it with the session id) on the page which pop's up the pop up window.

You cannot, as far as I know.

Do you have any other identifying details you can use to id the session variable? e.g. a user name?

If so then save the session variable to a database that server B can access. Along with that save put the user name. Don't use the session id as server B won't be able to use it properly.

If you don't have any other unique id then you could have a problem. I will give it a think over.

hi paul,

Thanx for ur reply...paul.I have tried to explain u the exact functionality,what i require and the problems i am facing.

Below is the link, i have given to the client, to access our server.

"Link to demo
"
Problem i am facing:
1.This link can be seen by everone who 'viewsource' the cleint page.Just the copy this link and pasting on a browser anyone can get access to my server, since i am checking in the databse for the querystring value.I wanna restrict unregistered users.

2.I can use servervariables("HTTP_REFERER"), it works fine if client wishes to open our pages in a window or frames, but if client wanna open in a popup window, i will not able to get the referer for validation.

3.I cannot give the client any more code for inserting into his page,since they are very arrogant and will not agree,hence rule out the idea of setting cookies or any other javascript functions.What ever we have to do is with our pages only.

This link has been given to 4 clients and two of them are opening in popups and other two in frames.From clients point of view functionality is fine but we are worried since the link is not secured.

Plz, paul give me some solution so that i can handle this.There is very less time and pressure is on.Hope u can understand.Thanks in advance!!Eagerly waiting for ur reply.

chandan

IE's scrollbar position

How can I get IE's vertical scrollbar position?

I user WM_HTML_GETOBJECT on IE's window to obtain IHTMLDocument2, then I do get_body to get IHTMLElement, following with QueryInterface for IHTMLElement2. Everything finish successfully, but every call to get_scrollTop returns a zero.
