Show The Result Of A Database Query, Every Second Or So

Apr 7, 2009

If I want to show the result of a database query, every second or so, is the best method using javascript/ajax with a set interval of a second to call a PHP script and update the DOM, or is there some other method better suited to this that would not have the cpu overhead if there were many users on the site.

Query :: Prevent Users To Access Data?

Mar 31, 2011

My problem is that users have the ability to manipulate querystrings to the point of being able to access data to which they should not have access to. The user logs in with their details and is redirected to their own data. The URL in the status bar is displayed without the &id=xxxx but in the source the &id=xxxx is present as a HREF. If the user adds &id=xxxx (Where x is any integer) they can access the data of other users. how to prevent this? To my mind, the best course of action would be to include id=xxxx in the session data and not to have it as a querystring but I would not know how to approach this.

JQuery :: Access Elements From The Result Of A $.get Request?

Aug 5, 2011

I am currently working on an website which consists of 2 sites. Both have the same design (expect for the colors) and both sites have different navigation items (some are the same). I started the page in PHP with classes. Every site is a Site class which has an array of Content classes.Site->showNavi($section); prints out the navigation of the current site, with a navigation item for each Content class in the array. The active ($section) item is highlighted.Site->showContent($section,$subsection); prints out the content.

First i just wanted to use AJAX for the content section but then I realised that I could use it also on getting thenavigation and the content without reloading the page. So i searched the web and decided to use jQuery.

I started with the change site/design links and with the help of an tutorial i quickly managed to get these links work with following code:

$("#site_navi a").click(function(){ var site = $(this).attr('rel');
var cssfile = "/css/"+ site +".css";
var headerimg = "/img/"+ site +"/logo.png";
$("#site_css").attr("href",cssfile);

[Code]....

But it didn't work and after some testing i realised that i can't access the elements (e.g. a.navigationitem) which Igot from the request from "ajax_get_navi.php", because if i write down the navigation in the html code it works.

So, is there a way to get access to these elements? If not what do i have to change in the ajax_get_navi request to get access?

Link A Link To User Submitted Query?

Apr 14, 2011

I'm working on a search engine that is just like google but customized for me and my friends. I have everything working well from the scripts supplied by google however they don't allow image searches. In order to combat this I added a link that links to google images. Is there a way to make the link go to google images and display my search keyword without having to retype it? The site is [URL] if you need to look at it.

JQuery :: Autocomplete: Implement Result() To Link A Selection?

Sep 3, 2009

I have autocomplete working for a list of colors(red, green, blue, etc). I created an array of $id's to match each color. For example if someone types and selects "red", I want it to go to a page like mypage.php?id=1. How can I (1) parse the ids in the array and (2) implement the result()
function so that it links to a page and posts the proper $id? I have a live example with source code here: [URL].. and if you would be kind enough to be as explicit as you can with examples on how to make an autocomplete result link to a page and pass an $id.[URL]..

HttpRequest And Timeout

Dec 20, 2005

I use an HttpRequest in my web application to launch an heavy
computation server side. The result is then send back to the browser.
The problem I got is that when the computation took too much time, then
I never get the result. I have to reload the page to get it.

I assume it's because my socket connection has time out, but my event
listener does not seems to get any event. Maybe I miss something:

function xmlhttpChange()
{
// looking fo a xmlhttp "loaded"
for (var i in nodeId2xmlHttp) {
if ((nodeId2xmlHttp[i] != null) && nodeId2xmlHttp[i].readyState ==
4) {
if (nodeId2xmlHttp[i].status==200) {
nodeId2xmlHttp[i] = null;
} else {
alert("Problem retrieving XML data (nodeId: " + i + ")");
nodeId2xmlHttp[i] = null;
}
}
}
}

My question is : how to handle XMLHttpRequest timeout. Any pointers?

Caching Problem With HTTPRequest?

Oct 28, 2005

I've created a page that uses HTTPRequest to include some
XML data and allow the user to update that data. The
problem is that the new data doesn't show up, even though
the XML file is changed.

I can call the XML file up in a separate browser window,
where I get the old data, refresh to get the new data, then
when I refresh the first browser, the new data appears on
the page.

I'm thinking this might be some sort of server caching
issue. Has anyone else run into this? Does anyone have a
solution?

HTTPRequest Problems Updating 'hidden' Objects?

Nov 23, 2005

I am finding some unusual behavior with techniques I am using to
show/hide/update data without having to refresh the page. I'm quite
sure it's developer ignorance on my part and would be grateful for any
suggestions.

My page has 10 tables with their visibility controlled by the user
making a menu selection. For example, selecting menu_1 calls a
function which displays table_1 by setting table_1's style display:
block and hides tables 2-10 by setting their respective styles to
display: none. Everything in this simple navigational approach works
as expected.

I am also using the HTTPRequest object to update relevant objects on
the page based on user input. The problem I am seeing is when the
HTTPRequest object is used to update DOM objects contained within the
"invisible" tables -- or more accurately within those tables having
their style display:none. I have tried using both the HTTPRequest
object's synchronous and asynchronous approach and am seeing the same
results.

I've tested when all of the tables are "visible" by setting their style
settings to display:block and HTTPRequest calls work as expected.

The other twist in my example is that these HTTPRequest calls are each
making a SQL query and updating a chart object within the table, which
may take about 500ms each to return. My initial impression is that it
looks as if the page is being rendered too fast because any more than
three charts on a page is when the charts start getting misplaced on
the page. Again, everything works fine when all tables are visible.

Is this a known problem with HTTPRequest, or do I need to migrate my
coding techniques to the 21th century?

HTTPRequest Freezes For 5 Minutes Intermittently And Throws "Unknown Name" Javascript Exception

Dec 4, 2006

I am using the Microsoft.XMLHTTP object to make server requests ie;
ajax. This is working 99% of the time but occasionally it will freeze
at the server for 5 minutes and then raise a javascript exception
"Unknown name".

After the exception I can run the same request ok, and keep doing so
until the next time it freezes for 5 minutes.

What does the "Unknown name" javascript exception mean?

Why does it freeze for 5 minutes?

I can't replicate this on my dev pc, it's only happening in a live
environment with IE6 and 2 load balanced IIS6 servers.

Refresh Query...

Aug 20, 2003

I have a page of rows of dynamic data... the user can click on a link for each entry... that allows them to open a popup window... add / edit or delete some sub-entries for each entry.

When they close the popup window, how can I get the background page to refresh and show the updated data... without pressing the refresh button...

a) could I get the page to refresh automatically every 30 seconds ?
b) could I get the popup to switch focus to the window that opened the popup and then refresh that page?

QUERY: IE Vs Firefox

Jun 21, 2006

I have created an array and store 3 functions in it. Eg.


this.validateCols = new Array();

this.validateCols[this.COST] = function(obj, index)
{
return 0;
};

this.validateCols[this.LOCKED] = function(obj, index)
{
return 0;
};

this.validateCols[this.COMPLETION] = function(obj, index)
{
return 0;
};


Calling validateCols[0](0, 0) works in IE, but in Firefox I get:

validateCols[0] is not a function


Is this the correct way to define functions in an array? Or is there a better way?
Or is this not supported at all in Firefox?


Q(2)
Also .swapNode() is not in Firefox? Any alternatives?



Q(3)

I implemented drag 'n' drop and it works in IE but not in Firefox.

Each droppable HTML TD element has:

ondragenter="this.parentNode.style.backgroundColor = 'gray' window.event.returnValue = false;"
ondragover="window.event.returnValue = false;"
ondragleave="this.parentNode.style.backgroundColor = 'white' window.event.returnValue = false;"
ondrop="OnDrop(this);"

Each draggable URL element has attributes:

id='draggable'
onmousemove='window.event.srcElement.dragDrop();'
ondragstart='window.event.dataTransfer.setData("text", "data");'

Walking DOM Query

Nov 28, 2006

I have a ul I want to access via the DOM that is here:

<div id="options>
<form>
<div>
<div>
<span>Some text</span>
<ul>
...
</ul>
</div>
</div>
</form>
</div>

Each child of #options has text nodes besides the HTML elements. Short of doing

document.getElementById('options').childNodes[1].childNodes[1].childNodes[1].childNodes[3]
or giving the UL an ID, is there any other way I could access that UL? I'm imagining something like an array containing every single child (even grandchildren, etc.) of #options but I don't know if it exists. I know the most sensible thing to do is to give the UL an ID, but I'm curious.
