I have been searching how to connect to a database and execute some queries, and then use the data that I get to populate some tables in a web page, all this using javascript.
I am confused because I have seen in some webpages that javascript is not designed to connect with databases, and also I have see other pages where they say that it is possible.
Does anyone know if it is possible to use javascript to connect to a database (informix), and execute some procedures or queries?
Is it possible to connect to a sqlite database via javascript. And I do not mean the HTML 5 Web SQL Database, that is no problem. What I mean is a file-based SQLite database, which is in the same folder as the HTML page.Also, I can not use something like Google's API, only the javascript libraries I can then put in this folder.

Here is what it needs to do..Create a database for a catalog. The database columns will be SKU (Stock Keeping Unit), DESC (Description), and UCOST (Unit Cost). The database will have 10 entries (rows) with the following SKUs:121, 232, 343, 501, 560, 603, 606, 747, 800, and 988.You may use any descriptive text for DESC. I suggest limiting the description to 20 or fewer characters. The unit cost will be in dollars and cents. The amount is up to you, but keep the it in the range $0.50 to $100.00. Also, keep the item and the price somewhat realistic.
Create a form to access the database. There will be 2 input boxes, one for the SKU number and one for quantity. There will be 3 output boxes, one for the Description, one for the Subtotal (price x quantity), and one for the Total Cost (a sales tax of 7% added to the subtotal). There will be 1 button to retrieve the data and display the result Description, Subtotal and Total Cost). Here is what I have so far..

Basically, we have phone server that is constantly streaming XML data on port 1024 (serverIP:1024). I've ran a packet sniffer and was able to gather the elements and attributes for the XML data that the server is streaming. Now, I have a test XML parser which works with the XML document using the elements and attributes i've gathered from the packet sniffer. Is there a way for me to connect to the TCP port i've mentioned using javascript and incorporate it with the XML parser that I have. code...

I thought about Ajax to send a request like that: insertDB.php?image=abc&name=dan&email=dan@dan.com but its some kind of a security issue since bots could register to my website. (just send GET requests..).

From what I can work out it looks like the person who wrote it is using jquery to determine the browser type. Any ideas why jquery would fail when passed through a reverse proxy?

I wrote an application using jquery/sortables and ran into a problem that I just don't understand well enough to tackle and hoping a jquery expert can see the solution where I don't.
I have a db setup like so
My page is setup to display multiple 'sortable' lists that allow the user to re-position elements (divs) with the mouse. Each div contains the 'content' (Bananas, Apples, etc) for users to see and they're even editable-in-place which all functions great.
THE PROBLEM: Each list has a class of 'biglist' in which I use the connectWith to allow these elements to be dragged from say myList3 to myList7.
Visually this looks great on the page but there's no DB functionality behind it to "SAVE" the new position. The only save that works is the elements position in its CURRENT list.
All 'content' in the fifth list for example is being generated from a SELECT statement [WHERE boxid = 5].
Each list has a different php file to generate its content that is virtuallyidentical
The order of each element is saved via a simple method in sortable's update function
Sorting is done here:
This is done roughly 10 times because there are ten lists. So here's the big question:
How can I pass the list's number (or create an ID for each list) that'll save WHICH list the items been moved to so that it's saved. (IE how can I change boxid instead of just Order)
here is the page I'm working onhere is the jQuery in use
$(document).ready(function() { $('.error,.success').hide(); $("#send").click(function (){ $('.error,.success').hide("slow"); $.ajax({ url: 'add.php?lnk='+$.URLEncode($('[name=lnk]').val())+'&
[code]....
and in this code, it works, the call is made and text is added. in the other code I don't get a change at all. Not even in the database that add.php manipulates.
