Resolved Autoscroll Div Up/down Loop?
Jun 22, 2010
What I'm trying to do just doesn't seem like it should be that difficult but I'm sure struggling with lacking skills I should say. I'm trying to automatically scroll a div up and down. For say if div.scrollTop = 0 then scroll to the bottom once it reaches the bottom scroll back up and so forth not stopping in a loop with say a timeout of 10.. Just need help putting it all together.
I've figured some stuff out:
I can tell if I'm at the bottom of the scrollable area with:
(document.getElementById(id).clientHeight + document.getElementById(id).scrollTop) - document.getElementById(id).scrollHeight
[Code]...

this is a homework project which kind of works but isn't perfect. My tutor said the result must be an alert but I ended up with a document.write instead.He said it was fine but I'd like to know how to make it alert the result if anyone can help.FWIW I tried making the contents of the for loop into a variable without success.

I've installed the jQuery autoscroll [URL], for my web page. I'm using it in a div tag for a news feed. The problem is that it is looping. Is there any way to make it stop at the bottom? And if its possible, is there any way to make it being able to scroll upwards again?

I have been looking at this code for two evenings now, and rewrote it 4 times already. It started out as jQuery code and now it's just concatenating strings together.
What I'm trying to do: Build a menu/outline using unordered lists from a multidimensional array.
What is happening: Inside the buildMenuHTML function, if I call buildMenuHTML, the for loop only happens once (i.e. only for 'i' having a value of '0'.) If I comment out the call to itself, it goes through the for loop all 3 times, but obviously the submenus are not created.
Here is the test object:
test = [
{
"name" : "Menu 1",
"url" : "menu1.html",
"submenu" : [
[Code].....
'Menu 2' and 'Menu 3' don't show up! I'm sure it's something small that I'm overlooking.

I'm looking to send a loop variable (i) to a function inside the loop, but I can't seem to get it to use the value I want, it keeps making it a reference of i and therefore the function is always called using the last value of i rather than the one it was set with.
So if i have 5 Tabs then Tab 1, when clicked, should call DefaultTabClick(0) and so on rather than always using 4 for any of the tabs.

As you can see from the code and the output, it will attempt to write to the browser how many moves, but only '0'.
function rollDie()
{
return Math.floor(Math.random() * 6) + 1;
}
/*
*searches for a number in a number array.

*function takes two arguments[CODE]...

I am trying to make an order form I am working on accessible for users who have javascript turned off in their browser, and to do this I would like to hide a div if JS is disabled.
Searching the Web has led me to think that styling the div to not display is the way forward and then using JS to display it. It is the JS bit I am struggling with! The div in question is a set of radio buttons to allow a purchaser to choose how many gift memberships they want to buy:
<div id="giftmember-buttons" style="display:none";>
<h2 class="threepeaksform">How many gift memberships do you wish to purchase?</h2>
<fieldset class="threepeaksform">
<legend>Please select the number of people you are buying a gift membership for using the buttons below.</legend>
<div class="generalcontactform-group">

I'm trying to create a test using Javascript. Actually, I did this in PHP, but we need to put it a server that does nor run it, I think I can convert it to Javascript. I hope it'll be work as in PHP somehow. Test will be composed of 15 questions and each question has either "Yes" or "No" as answer. And, I use radio buttons here for answers. By the way, there will be more than one radio groups. Now, I want to check the value of clicked radio button in each group and use an if-statement to determine if it's correct. And, if it's correct, I want to increment a variable by 1. Finally, by the resulted variable incremented for each question in the test, I want to use another if-statement to show specific result message for and interval of that variable.

I'm trying to add watch() to IE, and have more or less working code:[code]That works until I try to use setInterval with the code in red color. I never really tried OOP or prototyping in JS, so my whole approach to the problem might be wrong, but anyway, I think that if I execute that code in red every 100ms [for example], I'll be able to catch changes to properties on which the method is registered. Well, either my idea is wrong, or the execution.Some parts are commented out and method name is changed so that I could work in peace in FF.

I'm looking for a lightbox that allows me to have 3 lines of captions. Line one would be the art title, line two would be art dimensions, and line three would be media used. Would someone point me in the right direction? I have a lightbox that supports multiple lines, but doesn't allow for line breaks in the caption.

New to JS, and not too good at it. Trying to take some prewritten code and add script that displays some random text. Having trouble with assignment. Instructions are to replace a section of the file I am given with a script element. In the script element I am suppose to declare a variable named tipNum equal to a random integer between 1 and 10 returned by the randInt() function (which I made and have shown below). Then I am suppose to use a series of document.write() methods to write the following HTML code into the page:
<h1>Random Tip<br />title</h1>
<p>tip</p>
(Where "title" is the title of the random text as generated by the tipTitle() function from a external file, and which I did not make; and "tip" is the text of the random tip as genereated by the tipText() function, which is also from the external file, and not made by me) My code for the randInt() function is
function randInt(lower, upper) {
var size = ++(upper - lower);
var randValue = Math.floor(lower + size*Math.random());
}
The script I made to display the HTML code is
[Code]...
I am getting nothing on my page where the random text should be.

I have a form with multiple Divs containing radios, text etc. What I'm trying to do is write a function that will validate all radios only within a specified Div (in the code example below, Div4). I need to validate if all the radios in the div have "no" selected, or button[1]. If any have yes selected, then nothing happens. Only if all have No selected do I need something to happen.
Assigning radios to groups for validation is something I've done on a global (all of form) scale, but I can't figure how to be explicit to a div. The code below works, but only on individual radios, not groups. I've included a few buttons outside the div for effect. Oh, and the final product won't have alerts, it will be used to trigger a hidden div elsewhere in the form.

I want to change radio button values dependent on the selected item in a drop down list.The radio buttons have default values but I need them to be changed when the selection has been made in the drop down list and before the submit button has been pressed so the changed values will be written to the database.

I am working on a project using HTML and javascript to allow the user to choose a vehicle from a drop down menu, then load a new page showing some information about this vehicle. The information is stored in an Excel file. I posted regarding this issue a while back and got an excellent response from Old Pedant about using ActiveX - which has thus far worked perfectly. My initial condition was that I would only be using IE7+. However, my next idea was to be able to use it on an IPad (which I unfortunately do not own yet, making any kind of testing difficult) which I am fairly certain ActiveX won't work on. So, I was looking for any other method which would be similar.
Important note: this will not use the internet at all, all of these files will be available locally. There is a lot of material on running queries to servers, but I didn't think that would really apply here. It seems pretty clear that JS has difficulty accessing files client side (which I understand why completely), but I was hoping to find something that worked for the gray zone I'm currently working in since I'm not using servers at all.
I know that this is not really the intended use of HTML/JS, but I was hoping that by writing it as an HTML file, it'd be accessible to anyone with a browser. Some of my target computers have odd limitations (such as not being to download .exe files).The code I based my original off of is shown below:
<script type="text/javascript">
var conn = new ActiveXObject("ADODB.Connection")
conn.Open ( 'Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:fullpath oMyExcel.xls;Extended Properties="Excel 8.0;HDR=Yes;IMEX=1";)';
var sql = "SELECT * FROM [nameOfSheet$]";
var rs = conn.execute( sql )
