Ive been having a problem of late with one of my sites that uses PHP5 /
Ajax. The problem is that periodically the ajax functions lock up and it
gets stuck in the loading phase of the request. If i restart the apache
server everything goes back to normal (i assume it severs the connection
to the ajax called function).
I think this is a problem with the javascript part as i have tried it
using a straight post request and have have no problems and slow loading
time is localized to the one user (ie. still works fine on the other
computers on my office network).
I have recorded this happening in Firefox, safari and IE6 & 7
My server is running debian with apache2 and php5
Just wondering if somebody can shed some light on what my problem may be? Code:
I''m looking to develop a web app where there will be extensive Ajax queries, array manipulations and loading of tables on pages.. What are the best software programs or technologies out the fore maximizing the processing of these queries? ? i remember i once heard about some technology called PURE that let you transfer AJAX JSON responses directly into HTML to maximize speed.
Are there any good programs like that people know of ( or a better alternative to PURE if pure is no good i literally know nothing about it ) that can work well with jQuery, or can jQuery achieve better speeds somehow?
I'm working on a 'live search' for some products in my database. I use a web method in an aspx page to hit the database up for data. The search fires off on each keyup event.
Here's the code that is fired to get the search results:
My problem is that when a user types in the input field really fast, the whole page slows down, it looks like the user isn't typing and there is a lot of lag for the cursor to catch up with the current position. What can I do to prevent this slowdown in my input field and speed up my page responding to the user's typing? I'd really like to have fast results and response time like Google's search.
I've got the following site that loads great in FF and Chrome (no surprise), but is terribly slow in IE7. It's even quick in IE6, but not 7. Here's the site code...
Now I'm using JQuery in a couple places, but it's by no means nothing crazy. The page is fairly simple.
I thought of preloading the main content images, but even after they are loaded in the cycle, the loading time is still slow.
I read somewhere that putting Javascript code after CSS code on webpages makes them feel like they load faster. I was wondering if any of you has any experience with this and if you do follow this rule in your projects.
I am new at this jquery stuff. In fact, I'm more of a cut and paste kind of gal I have a web page that I incorporated a slideshow. The picture seems to change a bit faster than I'd like, and I can't seem to make the picture go slower than it already is. Can anyone tell me what value I need to change to accomplish this? I changed a couple numbers, but didn't seem to have an affect. Also, is there a way to add a pause and play button so if the fading picture bothers someone, they can pause it?
But the speed is considerably slow when the datas is large. I know that I can use just string concatenation and html() finally to speed it up but what can I do with the data()?
I'm justing wondering about the behavior of JS in regards to adding elements, suppose I have something like this:
I'm just wondering at the point I hit that "// DO SOMETHING WITH ONE OF THESE DIVS", are all the divs I have added in the DOM available to access?
I ask because I have some code at work in which a tester is reporting an error that happens which I can't reproduce, and they and others have had it a few times.
The only way I can explain it in my mind is if the div is not available to me at the time of execution. So I'm just looking to rule it out or confirm my hunch.
Is document.getElementById("myDiv").appendChild(obj); synchronous and the next line of code wont execute until the DOM is ready or is it in fact a asynchronous call and therefore adding alot of elements to the DOM could result in a lag so some divs or not available straight away.
In the home page (index.html) i have a flash intro. The first time a user sees the website, the intro should play. Once he goes to another page (about_us or contact_us) and comes back to the home page, it should show a different swf (the version without the intro) - i have created two swf files. I need to know how to change them when the user has already seen the intro or was in the home page before. When i googled, i found something on cookies. I have no clue on how to set them and change the swf file.
I can't change the speed on any jQuery functions that use that parameter, for example fadeIn(). No matter if I add slow, fast, 100, 180000... my tags/images/whatever always fade in at the same speed which is something between half and one second. Is this a bug?
I want to use animate function(changing the top value of UI tag)for the ui tags with a speed of 6000.Well the top value does change for the UI tag but it the animation is not visible meaning that it moves very fast.Instead it waits for 6000 ms and then at the 6th sec it suddenly changes the top value without giving the animation effect. This problem i m having only for UI tag below is the code
$('#van-one li a').mouseover( function() { $('#van-one li ul').animate({top:"25px"},6000,"linear"); } );
Im animating a div to go up, its a long animation upto -8000px but it doesnt show a fix speed, at the begining is really slow and speeds up then at the end it slows down.
I am trying to implement a div containing a form drop down on hover and I have everything working except for when I try to add any sort of animation or speed to the '.show' or '.hide' effect. When I try to add speed or seemingly any other effect to the div, the select elements of the search form fires the hover event. Does this make sense?
