Regular expressions are fantastic, but rather avoid the overhead of them in this case and just use; value.length. This works on all input controls with a value. e.g.
if (document.bestilling.fakturapostnr.value.length) >= 4) {<br />
....<br />
}
Also rather use getElementById than traversing the DOM with document.bestilling.fakturapostnr.

Yeah, I thought of that, but then again.... I need the length of the textfield to be exactly for digits, the format of a norwegian postal code.

I will look into that, thanks for the advice!

Apologies, but I am confused. value.length will give you the exact length of the value, so if they have only entered in three digits then it equals 3, if five digits then 5 etc.

I know.... But then again checking with value.length will match both "asdf" and "0000", which doesn't work in my case. I need to make sure the value entered is numeric.

Have you seen those web pages where they have those 3d environment pictures that you can rotate around to get a surround view? For example, this page[^]
Does anybody know how this is done? I've tried googling for it, but since I don't know what this effect is called, my search result wasn't too helpful. I've thought about flash, but I wanted to see if there's any other option.

You can create these panoramas using various different softwares, ranging from free to maybe around $100. The free one is called ADG Panorama[^], and is free for non-commercial use only. Quicktime also has some panorama builder softwares, but they're (IIRC) expensive.
They're usually viewed using the Quicktime browser plugin.

Thanks a bunch.
So they're called panorama viewers. I was going around keying things like "3D Scrollable picture viewer" and "Scrollable Environment tools" in Google. Suffice to say, I didn't get what I was looking for.  .

iPix was one of the original ones, search based on that and you will get plenty of related info.

Welp, i'm relatively new to linux, and i just got apache installed and running for my website. I'm wondering if there's a way to blovk recursive downloading. I've blocked wget, but it's nto working...people are changing the user-agent variable and spoofing it as Ie 6.0
does anyone know a way to prevent recursive downloading altogether?
thanks

Generally... no. If a normal web browser can see it, a site mirroring tool such as wget --recursive can see it too.
You could always try mod_throttle for Apache to set limits on how quickly the site can be mirrored, but a persistant user will still always be able to get through.

yeah, i was thinking about using mod_throttle, but unfortonately, there's a bandwidth cap on my server (i live in a dorm room, people on campus get great speeds, but anywhere off campus...slowness) so it would be hard to gague what the timeouts should be.

i coded submenus in javascript for a homepage. they work great on every browser and platform except for ie on a mac. i've debugged it and can't figure out why it still doesn't work on a mac. would love to tap javascript gurus out there. you can take a look at www.csudh.edu to view the source code.
thanks in advance,
donna

I don't have a Mac handy to look at the result. What problems are you seeing?
I've found in some cases you must explicitly set height and widths for elements before it looks good on a Mac
|
|
|
|

the javascript submenus don't align correctly to the top navigation bar. they fall a few inches below. it aligns perfectly in other browsers though.
|
|
|
|
|
Ran into this myself. I had to position the menus relative to a fixed element.

Hi all
i have the below functions which i use to validate a login, albeit not very well !
this is called when the user submits the form, all it does it checked they have entered something
what i need to do is to throw out an error when a user enters an alpha (a-Z) character as well
but im getting a bit stuck, can ne1 point me in the right direction here ???
thanks
si
function isblank(s)
{
for(var i=0; i < s.length; i++){
var c=s.charAt(i);
if((c!=' ') && (c!='\n') && (c!='\t')) return false;
}
return true;
}
function verify(f)
{
var msg;
var empty_fields="";
var errors="";
for (var i=0; i < f.length; i++) {
var e = f.elements[i];
if ((e.type == "text") || (e.type == "password")) {
if ((e.value=="") || isblank(e.value)){
empty_fields += "\n "+e.name;
continue;
}
}
}
if (!empty_fields && !errors) return true;
msg = "___________________________________________________________\n\n"
msg += "The login action could not been performed because of the following error(s).\n";
msg += "___________________________________________________________\n\n";
if(empty_fields){
msg +="The following required field(s) are empty:" + empty_fields + "\n";
if (errors) msg+="\n";
}
msg+=errors;
alert(msg);
return false;
}

Have you looked into using Regular Expressions?

use in this way, first store alpha charcater in string, and then chk character in this string.
function isblank(s)
{
var c;
var chkstring="a,b,c,d,e,f....";
for(var i=0; i < s.length; i++){
var c=s.charAt(i);
if(chkstring.charAt(c) > 0)
{
alert("Can not enter a-z messages here");
return false;
}
}
return true;
}

You should start by correcting your basic approach: instead of looking for errors in the input you should be testing for correct input and giving an error message if the test fails. See this article on data validation

How can I count the number of online users on my site? I have implemented my application as follows. Whenever a user logs in, I increment the count field in my database by 1 in Session_Begin and on Session_End I decrement it by 1.Though the code works fine in normal circumstances, I noticed a few anamolies:
1. If the user refreshes his browser, the Session_Begin is called again and the counter is incremented again. To overcome this, I used cookies. The first time the user logs in, I create the cookie. When the user refreshes his browser, it checks if the cookie exists, if it doesnt it treats it as a new request and updates the counter accordingly.
2. The problem arises on log out. Whenever the user refreshes his browser, Session_End is called that many times, and my counter is decremented more than once. How can I get Session_End to run only once for each instance of the browser?
3. I'm using Forms Authentication and on Session_End I want to call FormsAuthentication.SignOut since the user can still access the pages after the session ends,causing a new session to be started. But this function does not work in Session_End.
|
|
|
|
|
How about creating a dynamic array (ArrayList for instance) of the Session IDs? On Session_Begin, add the ID to the array if it doesn't currently exist, on Session_End, remove the Session_ID. TrimToSize each time and use the Count to get the number of active sessions.
I seem to remember a similar solution in traditional ASP using the Dictionary object...

Use application variable instead of session variable. Now U become free from session. Now check if page is refreshed by session variable. If the browser is refreshed and new session start then chk it on higher version browser, or better ie 5.5 and netscape 7.0, and I think this problem will not exist. If still exist then you have nothing to do.
But I am sure the problem will not exist.
