JQuery :: Autocomplete With A Large Database?
Feb 17, 2011
I am new to jQuery and I am trying to create an autocomplete textbox. When I use a small test database, it works fine but when I use my production database with over 3000 records, it slows to a crawl. It take >20 seconds to load the page and with each letter I type (even though I set minChars to 3), the browser times out asking if I want to continue running the script. My feeling is I need to use AJAX but I have never done that and don't know how to. I code in classic ASP with an Access database. Can anyone provide some sample code how to do this. Unfortunately I am under a time pressure to complete this project.

I need a plugin or a idea about how to develop a pagination using jQuery (JSON dict coming from the DB (postgre)), but i cant get a list of all itens in the DB. I tried using offset and limit from the DB, but i didnt like the large algorithm. All i need is: develop a pagination that gives me only 20 rows from the DB (without calling a query to paginate all table from DB) and build a pagination with "first page, previous page, X-2, X-1, X, X+1, X+2, next page, last page" (X = number of actual page).

The correct syntax for an array literal would be:
this.managers [ "DOE, JANE", "DOE, JOHN", "BUSH, GEORGE W" ];
(which works)
My questioin is, how do you recreate this same syntax pulling from a
recordset containing over 3500 records such as:
aManagerName = "DOE, JANE", "DOE, JOHN", "BUSH, GEORGE W", etc...
because
this.managers [ aManagerName ];
(does not work)

So I have a nice little hand rolled Ajax call to my server pulling a list from the database and displaying it in a drop down list dependant on the user input. Aka Google suggest. I am wondering if the quickest way to do this is to call the database each time with Ajax and search the results with the input, or to write an xml from the database and search that. Then when the Database is updated rewrite the xml file.
Am I underestimating MYSQL again? Or not, and I feel it would be good practice to write the xml file because it will essentially mean a lot less database calls. But I don�t know how fast searching an xml file would be in comparison to a db call. The results from the database are say 500 entries anywhere between 10 - 100 characters each. I want to know A. The best way to do this B. Lets say the site will have pretty high traffic so I am looking for it to be as tweeked as possible. I can test but thought at the end of my week it was worth seeing what peoples advice is.

I am looking for an Ajax combobox (drop down, not a text box) auto complete script. I searched for it on Google and only result which seems similar to what I am looking for, is dhtmlxCombo. And that one is too complicated for me. What I basicly need is:
When the client types on the drop down, the records appear from MySQL database and when the client chooses one and submits the form, I want the ID (not the text written) to be posted.

Does anyone have a library or patch to call a handler if a user leaves an autocomplete field without choosing one of the autocomplete options - i.e. they've entered free text. I'm working with an app that populates multiple fields from a single auto-complete value, and our latest requirement is to clear out a bunch of fields if the user's entered something manually - rejecting autocomplete suggestions. My initial attempts at hooking into onkeyfoo and onblur haven't lead anywhere productive, and I'm hoping someone else has managed to overcome the gnarly event and timing dependencies involved with onkeyfoo and blur being used for standard autocomplete behaviour.

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?

'm coming from the Java/Flex world and trying to get my mind around jQuery/HTML5 to evaluate how you would build a large scale application using them. One issue that I can't quite grasp is how to deal with HTML element IDs. My understanding is that jQuery allows you to manipulate HTML elements by referencing them by ID (there are other ways but those seem to require grabbing a list of elements and sorting through them to find the right one) In a large application with namespaced code how do you deal with dynamically created elements and the IDs the elements may contain?
For example, lets say you have a dashboard app that can contain a number of reports, each report is basically a div with the report content (a chart or table) and some associated views that can edit the report's data model. How can I assure that IDs for the report's subcomponents don't collide with IDs elsewhere in the application? I can envision some programmer working on a large project in a team naming a custom widget 'MyWidget' and then some other programmer naming their widget 'MyWidget' effectively causing two 'MyWidget' IDs to be assigned to different elements.
In the OOP world this isn't an issue because programmer one's widget is really something like MyForm.MyDiv.MyWidget and programmer two's widget is MyForm.MyOtherDiv.MyWidget allowing them to have unique names.
This could just be a fundamental misunderstanding of how things work in HTML but from what I've done every ID assignment is basically a global variable.

I have approximately a 400-500 row table (2 of them) each with 12 columns of formatted content such as currency, percentage, name.
I tried this with [url] but it can't seem to handle that much data.
Does anyone have a good plugin for large data on the page? (and no not interested in paginating it really)

I'm a graphic designer with some experience in Actionscript/HTML/CSS. I'm now trying my hand on jQuery.
My goal is to achieve an effect to scroll a large image, something like this Flash example:
[URL]
Below my result so far. It kind of works but nowhere near as smooth as i want it to be.
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>slide scroll</title>

I have a website using jQuery that for the most part works fine, but it contains a very large form with a lot of fields. I have an option to save the settings from the form and to load and retrieve them from the server. The problem I'm running into is that the loading settings involves changing so much in the DOM (the form is huge and contains a lot of fields) that it seems to be freezing up on some browsers or timing out. I can't reproduce this on my computer (although it does take awhile to finish processing) but I've gotten enough reports of the problem that I'm looking for some advice as to how I can speed it up some.
The site is [URL] I've tried to speed it up by caching a good chunk of the selectors I'm interacting with and I'm using IDs to access the fields in most circumstances. But I'm not sure what else I can do to really optimize the loading. how I can go about improving on the load speed?

I'm using animate() on images with sizes like 1100x1600 px. In Chrome and Firefox the animation isn't that bad (although not at all smooth) and in Safari even worse. Is it impossible for jquery to smoothen the animation with such big images? Are there any js libraries which do this better?[URL]..

I'm building on-the-fly <select> lists from JSON data fetched from the server. Some of then include a large number of items (>20,000).
The SQL and HTML parts are working fine. The AJAX script fetches data fairly quickly (around 1 second) and large selects are not a problem once they're built (the browser handles them nicely, even IE). The bottleneck is in the process of picking the JSON data and building the <option> tags. That can take a full minute.
What's the recommended (i.e. fastest) method to generate a large <select> list?
My current approach is this:
// Fetch data (GET method allows me to use browser cache)
$.get(url, get, function(jsonValues, txtStatus){
that.values = jsonValues;
}, "json");
[Code].....
