Dynamically Showing Information
Mar 25, 2004
Is there a way of dynamically showing information from a sql server database in a web page without doing a postback.
My goal is to display information from a sql server database everytime the underlying table has received a change. I will also need to have the ability to format the cells based on the information being populated.
If anyone knows of any technology on this topic, or has attempted to do something similar please respond. Even if it's not quite what I'm looking for, the advice given may spin me in the right direction.
It is my belief that this may require creating this web page through a sql server wizard that offers the ability to watch the table for underlying changes. However I am not so sure about how I would then format the information displayed. Has anyone used this technology before?

I'm looking for a snippet of code. I am not sure what it is called, so I will have to describe it by example: I have a vertical navigation via styled <ul> like below (let's pretend this is a styled vertical navigation lol) Activities
+ Party at the Party Place
+ Concert at the Stadium
+ Stand-up Comedy at the Funny Place
So we have three "links" above, each listing an "activity". However, I want to provide more details about each activity. I wish to provide more details when the user clicks on the link. Like so:

I apologize in advance for my ignorance. I'm relatively new to javascript. I am trying to dynamically create a page based on information in a .txt. So far the code works. But only for a spacific line in the .txt. I would like it to create numbered divs and fill with approprate info from .txt for each line in .txt. Does that make sense? I will paste full code if necessary and it is explained exactly how. Is it: ["my code goes here"] or

I have a HTML form containing two text box controls in it and a submit button. When a user enters information in those two textboxes and click on submit, the information is sent to a function in Javascript. In the javascript, the information from those textboxes is stored in a javascript variable. The problem is as follows:When I am inputting string text in the html text boxes and in the javascript when I am trying to print those values, it is giving me out an error saying NaN. However when i input integer values in the text boxes it is printing those numbers. Is there a conversion that I have to do for the string to be printed. I am new to Javascript and need your help. This is a basic code of Javascript. Below is the code that I have.
<html>
<script type = "text/javascript">
function square(form)
[code]....

I am using the Collapsible Checkbox Tree jquery Plugin.For that I have inserted this linein the javascrypt code:
When I make a list in the HTML code using the <ul id="example"> works perfectly.
But when I tried to make the list dynamically calling a JSON file, does not works fine.
If I insert theready(fn) mentioned above inside the javascrypt function that create dynamically the element<ul >as is shown next:
Improves a little bit, but still does not work fine. Specifically does not show the plus and minus sign, then I can not open or collapse it.
I tried also with thecheckboxtree pluginand I encountered the same problem.

At this point I have been able to add the row. But what I want to do and am having trouble with is alternating the row colour to the dynamically added row element.
Sample of code I am using:
Code:
var tbody = document.getElementById('tableItems');
var row = document.createElement("tr");
var remainder = tbody.rows.length % 2;
if(remainder) {
row.setAttribute("class", "rowLightGreen");
}
var td1 = document.createElement("td");
td1.appendChild(document.createTextNode(qty));
td1.setAttribute("class","qty");
row.appendChild(td1);
tbody.appendChild(row);
One thing that puzzles me, is that even after adding a row the table my table.rows.length still = 0.
Does anyone know how I can determine the appropriate amount of rows so that I can apply the appropriate class?
Or is there just something blatantly wrong in my approach?

Before i submit my problem just to let you know i've been using jquery and javascripting for about a month or 2 now so i appologise in advance if this is something stupid. My main issue is that i want this to select from a database so i found out that you can get information from php files i just couldn't figure out how to get the variables it submits. I then found out that i can use xml to get the information to the script. but the code i have written doesn't seem to display anything. The code in red is what i think the issue is.

Our project is to optimize gcc's instruction scheduling. It requires us to specify architecture information
(basically number of cycles per instruction, stall and branch delays) to gcc, to optimize structural hazard detection.
Problem: Is there any specific format in which we can specify this information to gcc? Is it possible to embed this additional architecture specific detail, in .md files?[code]...

I would like to put a welcome message on one of my sites... something like "welcome username!" with the username being the login name that that person used to login to their computers.
Is it possible to gather this information using client-side js? if not, how can i accomplish this without having each person enter their name upon entering the page?

I am currently in the process of writing an interactive calendar in jscript. It's my first major project so bear with me please, I'm quite new :P.
I was hoping to add a section of code to the calendar which would allow me to display events happening on a certain date and add new ones etc.
However I was not sure how best to store the information as I know javascript is not 'designed' to access files. I was wondering maybe a cookie or learning how to use SQL? Or is there something that I haven't come accross yet?

I am doing this:
window.location="page2.php?subj="+subj+"&body="+body;
to send information to another page.
However, I don't want that second page to show up or display in any way.
There is only behind-the-scenes work going on in that page.
How do I pass the information to that page so that it is only processed and
does not launch a window?

Is there anyway I can get the username and domain of the user accessing a
webpage using somekind of client side script. Users accessing the page are
always Windows users.
The actual scenario is, I need to allow the access to the page only if the
user is logged onto a domain. If user is not logged in to the domain deny
access.

Is there anyway to use javascript to be able to retrieve information from
someone, then have it post to a text document on a server? Without
overwriting whats in the document at the time. The server I'm using doesn't
support php, asp, or anything to be able to database (that and i don't even
know how, yet). Plus, I don't need it to retrieve from a database...just a
simple text file that can be written to and read from.

This functions great, but when the form is submitted the fields that rely on the script are not transmitted. I am using FrontPage for my forms and would like to continue, if possible. The fields "Option1" & "Option2" are the fields that aren't being submitted correctly. If I don't select these options then EMPTY is submitted, correctly. If I select a value such as Topic1, then the form is submitted with the answer blank. Code:

I have select words that are within a <span class="word">example</span>. I need to make javascript pull the word "example" here so I can use that as a search term, and return the value which is linked to that word in an array. What would be the best way to do this?
var arrElements = document.getElementsByTagName('span');
var words = new Array();
for (i = 0; i < arrElements.length; i++)
{
// Save the current element
oElement = arrElements[i];
if(oElement.className == "word")
