Hi Marc,
Thank's for the reply! I don't believe so. I wasn't thinking at the time but a few lines up in the code that I didn't copy I am initalizing 'Current' and setting it equal to whatever I have saved in my hidden variable. I have since changed it to a 'while' block instead:
while (Current < stopValue) {
It's just so weird though... I put an 'alert' line displaying both values in right after the while block and sure enough, I can watch it as it counts: (Current = 3; stopValue = 5, Current = 4; stopValue = 5, Current = 5; stopValue = 5) but rather than stopping like I thought it should, it continues through the while statement and causes the problem. (because I have a set amount of elements and when it tries to find that 5th element it comes back null. I understand the easiest fix I'm sure is to just subtract 1 from the stop value, but I would still like to discover why the function is seeing 5 < 5 as true?

have you tried:
for (i=Current; i < stopValue; i++) {
|
|
|
|

Yea, that still does the same thing :/ it's just weird!

You could try posting your code whole - I might be able to help more.

function scroller_set(direction) {
var imageObjects = new Array();
imageObjects = grabObjects();
var images = document.getElementsByName("selector");
var Current = parseInt(document.getElementById("scroller_current_value").value);
var image_counter = 0;
if ((direction == "next") && (Current < imageObjects.length)) {
document.getElementById('backButton').style.visibility = 'visible';
var stopValue = Current + 5;
while (Current < stopValue) {
if (Current < imageObjects.length) {
var imageLoader = new Image();

I think I got it figured out. Although I'm setting the variable as an interger, I still need to use 'parseInt()' on all of my "current" variables that deal with any sort of logic gate. Is there a way you can specify a variable in javascript so that I don't need to use 'parseInt()' every time?

I don't think so. Unless you remove any logic that make js think it's dealing with a string.

Ah, turns out that wasn't it after all. If I remove the image.onload section, then it works, although it never changes to the desired image after it loads. I guess it's coming back to the 'onload' function after Current has hit 5 and that's where it's bombing out. I'll have to search for dynamic image.onload functions. So far, I've been basing my code from this
[Update] it is definately something to do with the image.onload event. I was able to finally step through the code and it does work fine, but it appears that after the function completes, it then goes off and works on the rest of the page before coming back to the code in the image.onload event. Then, it tries to execute those lines of code but fails because the image_Counter is now 5. I thought that the image.onload would be setting a new function for each image box, but instead it looks like that is not the case. The overall goal is to have a "loading" gif display as the thumbnails are loading, but then display the image once it is properly loaded. I can get it to work just fine with a single static image, but not programatically for each of the thumbnails. Does anyone have any recommendations to help point me in the right direction?

Hello All..
I have designed a web page containing a Templated GridView,
In which, I am adding Rows from JavaScript Using AppendChild Method.
Now When The page goes to the server side, It cant find new rows which are added from the ClientSide.
How to Solve this?
Please Help.
Thanks & Regards,
Bhavin.

First, understand the tools you are working with. The ASP.NET GridView is a databound server control, when the page is posted back the grid is loaded from viewstate and rebound, if called. Since the rows added on the clientside are not part of the viewstate, they will not be added to the gridview on the serverside.

hi , i have made a div that is hidden unless you click an image, and the div contains like a larger image which you click .... The problem i have is the positioning. The image is in a IFRAME with the images , so when i position it the DIV is positioned in the IFRAME, i don't want that , i want it outside the IFRAME ... how do i do it ? thanks

Is there any reason you must use an iframe?

kinda , as all the content is displayed in the i frame when you select like a game from a menu , and this kind of saves time i think as u don't have to do the whole page again

You should look into AJAX. (& no, I'm not kidding - it's not just a cleaning product, trust me  )

Sounds like you are unsure of the technology as to what it is and how to use it. As others have suggested, look in to AJAX

i am sure of it as i have been used to the technology , i haven't tried AJAX before so i was only wondering if CSS can do it .... so by kinda , i meant i want it to

Hi,
I have a combobox (aka select) with some options retrieved from the database..
The user might choose one item from there or click next to the combo on "Other".
Here is the thing:
I wan't to show a dialog that lets the user to add a new registry to the database
and after that, the dialog should be closed and the combo should have the new option without a simple refresh (an HTTP GET, because this would erase all the form input)..
So..
Any tutorials for this? Im sure this is some typical procedure..
In winforms this is really easy because of events.. but in web?
More notes:
-The dialog should block the parent window (javascript?)
-Its like the "add new label" dialog when you are seeing a message in Gmail
-The form that haves the combo shouldnt lose the current input (ajax?)
-I'm using ASP.NET MVC and LINQ TO SQL.
Please help!

Yes[^]

Those are CLIENT SIDED events...
Did you at least read the post?

More than once. If you are interested in controlling this on the server side, I suggest you go here[^]
However, most of you wanted to do doesn't require going back to the server to accomplish. I'd use JavaScript to get the input and then fire off a postback using the value you got from the user as the arg.
