JQuery :: Multiple Bindings On One Site Slow Down Performance?
May 11, 2010On our website we wanna bind a click (or maybe mouseover)-event on every user-image. The click on the image should open a layer with further information about the user. Now i look for a best practice way to solve this (focus on performance), because there could be a lot of user-images on one side. I think, if i bind the event on a class like this
jQuery('.myclass').bind('click', function(
makerequest;
openlayer;
))
that could slow down the site, because i read, that "The class selector is the slowest selector in jQuery". Back to the roots and insert an onclick(function) to the element, but i'm not realy happy with that solution.

JQuery :: Slider Toggle - Slider Div To Be Visible If Js Was Disabled

Aug 11, 2010I have to change the slider color depending on its value, but I didn't manage to do it, I changed the attribute "background" of the class "ui-slider-range" this way : $("#slider.ui-slider-range").css("background","red"); Since I have three states (red, orange and green) I have to use three sliders, each one has one color, all hidden at the beginning then I show the appropriate slider when the value changes.

<option>1</option>
<option>1</option>
</select>
is there an easy way to transform that into a slider?
JQuery :: Performance - Moving Everything From One Div To Another
May 27, 2010I need to move the entire contents of one div to a sibling div. At present I'm just doing (assuming the 2 divs are called 1st and 2nd):
What I need to know is if this is the quickest means (in performance terms) of doing this as I will be performing the operation regularly and on a large number of nodes and it's in an area where the UX really can't stutter ?

View 2 Replies View RelatedJQuery :: Selector Performance - Tester ?
Jul 2, 2009I just tested all my jQuery selectors using the jQuery Tester [url], and the results seem to "contradict" one thing I read in a performance article: that you should descend from the closest parent ID when using classes in your selector (the article says "April 09", so the latest jQuery version was already available). In my tests, using just the class selector (like span.myClass) was always fastest (sometimes twice as fast as #myDiv span.myClass), and this in all browsers I tested, not just the ones supporting getElementsByClassName. Maybe descending from the closest parent ID becomes a factor when you have a lot of elements on you page?
View 6 Replies View RelatedJQuery :: Poor Performance Of XML Parsing
Apr 2, 2010I pull XML from server using .load() and then iterate with .each() over some 3000 nodes. I use .find() to get 7 sub-nodes and store them internally (into arrays). It works, but it is disappointingly slow. On my obsolete P4 it can take 8-10 seconds during which the whole browser (FF) is completely frozen. On faster computers the processing time is shorter, but still way too long. What can I do to cut this time? I certainly need speed up of an order, two orders would be nice. Would JSON be any faster? Or should I pull text/plain in custom format and parse it in my JS code?
View 5 Replies View RelatedJQuery :: Terrible Selector Performance In IE 8?
Apr 7, 2010I have a php search page with can potentially display several hundred records. For each record, there is an icon which, when clicked, makes an ajax call. When the reply comes back, the text returned from the server script is added to a specific div and the source of the icon that the user clicked is changed (as a visual cue that that particular item was selected).
This works 100% perfect in FireFox (3.5.9), Chrome, and IE 7. However when I test it in IE 8 there is a HUGE lag between when the icon is clicked and when the div and icon are updated (usually between 10-15 seconds). By commenting out one line at a time, I've narrowed it down to the line that changes the src attribute of the icon...if I just comment that line out, the ajax call is made and the div is updated instantaneously.

JQuery :: Performance For Different DOM Node Creation Methods?
Dec 3, 2010Does anyone know if there is a significant performance difference between the below two methods of DOM creation in jQuery?
Method 1:
$("<div id='myId' class='one two three' style='width:100px; height:100px; z-index:1;' />").appendTo("body");
Method 2:
$("<div />").attr("id", "myId").addClass("one two three").width(100).height(100).css("z-index", 1).appendTo("body");
I imagine that when using the first method, jQuery does some string processing and eventually ends up doing the same thing as method #2. Is that correct? If so is there a significant performance cost for this? Overall I think the first method is better as far as readability goes but it would be good to also know its effect on performance.
JQuery :: Multiple Parallel Ajax Calls - Improving Performance?
Apr 23, 2010I'm trying to build a page that has multiple ajax calls on it. When you do it the old-fashioned way with XmlHttpRequest, you'd create a new xhr object for every call so that they execute simultaneously. If I try to do this in jquery it will only execute a call when the previous one has completed. This makes the page load time completely unacceptable. How to improve the performance?

Performance Using Tables Vs Divs
Jul 14, 2010I have some code which creates an extremely long table row, and I've been able to clean it up to a point where my performance is fairly decent. What I am trying to figure out is if its better in terms of speed to use divs as opposed to the really long table row. I didn't really find much on this topic online, so thought I'd ask out here.
View 2 Replies View Related<select>.remove() Performance And Necessity
Apr 26, 2007I have read many of the copius entries on the subject of IE performance (or
the lack thereof) when populating Select Lists.
I don't mind the insert performance so much, (I get 100x120byte rows
inserted/sec up to 500, and 100rows/6secs up to 3000, which isn't great but
then the Row Count is clicking away for the user to see and they can hit the
"cancel" button at anytime, so overall I'm happy), what really disappoints
me is the woeful of .REMOVE()!
Before fetching the next result-set I clear down the existing options (I
*do* have to do this don't I?) by looping through option collection calling
remove(1). (Would it be quicker if I removed the last option? Option[0] is a
header.) For 3000 rows this takes an unbelievable 20+secs :-( Does this
sound about right?
1) Is it only IE that performs badly on this?
2) Is there a quicker or more efficient way of zeroing the Select List?
2a) The w3schools ref says the "length" attribute "Returns the number of
options in a dropdown list" it doesn't say "sets Or returns"
2b) The French guy (Stephane?) suggested that I should just set the length
to zero, but wouldn't that result in a memory leak?
3) Do I need to create a malloc/realloc function that keeps a high-water
mark of available option objects for this Drop Down and only "new" some more
options when that's exceeded? (But then the Length would always be off)
4) Use tables and not select lists?
5) Use another browser
CBE/ X Menus, Performance, Dynamic Generation
Nov 18, 2003I've been working on a redesign of our site at ExperiencePlus for some time now, and long ago chose CBE menu 9 over the other menu technologies out there because of its browser independance. Problem is, as you can see, we have a pretty large site; load-times for the menus and associated scripts are approaching prohibitive. So I'm trying to speed things up.
You can see the results of some simplification here - still about the same speed by my guesstimates.
So, my question is twofold, I guess. First, Mike, do you have any ideas about how long it will take X menu 4 to reach maturity? No pressure ;^) If it were ready now, I'd just drop CBE in favor of X.
Second question: How much performance improvement can I expect from removing unnecessary code (sliding, for example) from the CBE core files? I haven't played with that stuff at all, except to read it now & then when looking for solutions to problems. Does anyone have a similarly large implementation of CBE menu9 that runs faster, so that perhaps they could share their experience?
One final thing: I'm planning to eventually shove all this into a PHP document that will auto-generate chunks of the menu from database queries, especially around the tour & country listings and our "Resource Room." (X menu 4 looks like it would be vastly superior for that purpose, since it's so lean.) I'm interested in hearing from anybody who's tried to do something like this, whether they succeeded or not.
JavaScript Includes Performance Question
Apr 16, 2004I have client that has 5 versions of the same site located in web viewable root folders on his server. Aside from a few minor differences such as prices, download url's and a few text and image differences, they're the same.
Just wanted to get some opinion as to how many javascript includes I can, or should, use on the site pages or if there are any strong opinions on not doing it this way.
I'd like to place a set of javascipt files in a folder within each site, then have all pages in each site call to their specific include folder. This way I'll be able to use a single set of DW templates to manage the content on all the sites.
I can't convert to php, use ssi nor create a dynamic solution since the sites are already live and rank well in the search engines, The content I'll be wrapping in the includes is not important search engine text content.

Jun 9, 2009This questions mainly regards using google's analytics code on some of our websites. We currently place the code at the footer as it can hinder load times if placed further up in the page.

Script Slows Page Render Performance - Fix?
Jan 23, 2010I have a nice javascript slideshow but it kills the rendering speed of my home page. According to Yahoo performance guru(s), javascript gets run before other stuff is rendered, so you fix that by putting the js code "at the end" of the html file.
Putting it at the end puts the slideshow at the bottom which is not the desired result. And even abs positioning is slave to the <div> structure.
How do I nullify the flow just for this one thing (I don't want to make the whole page absolute).
