JQuery :: Multiselect Plugin - Speed - Lags When Have Multiple Instances - Crash The Browser In Some Cases
Feb 28, 2010
I am having some issues using jQuery multi-select, it works fine but really lags when I have multiple instances (can crash the browser in some cases) am using jQuery 1.3 & jQuery 1.7 as the demo (have tried updating to the newer versions but problems persists)
I am using the following [url]
Does anyone have any idea to speed this up, or an alternative plugin that works a little better?
I came across a problem with multiselect plugin(we have multiple options with checkboxes in drop down). If there are two absolute divs in different panels, when we open the multiselect, it hides behinds the second div. May be its because of the nature of z-index in IE.
I'm somewhat new to jQuery and writing jQuery plugins, but I'm trying to find a way to be able to have seperate instances of a jQuery plugin with different options.So far, the tutorials I've come across can allow multiple instaces, but the options are not independent.This is the framework I've constructed:
I'm writing some code so that my comments section automatically updates every 10 seconds. The code i wrote does update it but sends off about 40 request every 10 seconds until it eventually crashes the browser.
I have this table:CREATE TABLE IF NOT EXISTS Assignments (uid TEXT PRIMARY KEY ON CONFLICT REPLACE, instruction TEXT, start TEXT, stop TEXT, createdTimestamp TEXT, theTimestamp TEXT, taskID TEXT, resID TEXT, flowID TEXT, flowDefID TEXT, currentState TEXT, iconRef TEXT, colorRef TEXT, dispatched BOOLEAN, inStartState INTEGER, inStopState INTEGER, writeLock INTEGER, workItemID TEXT, companyID TEXT, metadata INTEGER)
The thing is that when making a insert and then going to the development toolbar in chrome and look at the storage tab and look at my table. Depending on what is in the table chrome crashes.I drop the table between the executions.The difference here is that "theTimestamp" is something rather then empty. If I set theTimestamp to '10/15/10 3:07 P' it works. But just adding that last M or any other letter will make chrome crash when you try to look at the table. Whether it is by navigating to the table with mouse clicks or writing a select * from Assignments statement.
So I have set the speed, timeout and delay for my transitions. If I launch the page and let it autoplay the timing is great. However when I click one of the links on the right and it changes slides, or I click a link in one of the slides the timing between slides increasesI am not sure what I am doing wrong as I have not defined timing anywhere else. Below is the code that I am using.
I use cycle for a news scroller, the slides do not stay long enough on the screen and I want to slow this down but i can't find out how. I have used delay but it only affects the first slide.
I'm using a multiselect box on my website, similar to this one: <Select Name="multiselect[]" multiple="multiple"> <option>This is option 1</option> <option>This is option 2</option> <option>This is option 3</option> <option>This is option 4</option> </select>
Now I want to set option 1, option 2 and option 3 as selected (highlighted) in javascript. How would I go about doing this? I tried something like this: document.taakform.elements['multiselect[]'].selectedIndex = "1" document.taakform.elements['multiselect[]'].selectedIndex = "2" document.taakform.elements['multiselect[]'].selectedIndex = "3"
I am using the cycle plugin on the homepage of my website and it it taking 6.5s ish to fully load the page. All the elements are loaded in less than 1s but it takes 5s plus to render the final page. Is this a CSS issue or is there a better way of using the cycle plugin?
I have a simple navigation menu. On hover, the block element changes background color. I'm also fading in/out a div layer. I'm also using the jQuery Color Animations plugin. Very simple to accomplish and I had no trouble doing so.However, I don't want to have to use a whole new function for each individual element, so I wrote the following:
$("div[id^=div]").css('display','none'); $("a[id^=a-nav]").hover(function() { var tabSelected = $(this).attr("id");
I have added the Flowplayer jQuery scrollable slider to the web page linked below and I am trying to add more than one instance of the slider to that page. So essentially three galleries. Can someone figure out how to rewrite the jQuery function to accommodate the additional scrollable items on the page?
ove the plug-in but have come across a puzzle. i am trying to use multiple (5-8) instances of the jTip theme, jTip Style clueTip. The first tip shows as expected using the code <a class="jt" href="health.html" rel="health.html">Health</a> However, the second tip shows the new ajax file but as soon as i move off of the word, the tooltip closes. i know this has something to do with the jt:eq() class, but i'm having no luck in changing it to make the second instance stay open on hovering.
i somehow figured out how to have multiple instances of the jquery scrollbar on the same page - however, i would like to use those scrollable divs in a auto-centered fixed width layout. i cannot seem to be able to modify the code in a way so the scrollbars move with the centered layout.i could imagine this could be of interest for others too since this technique finally gives cross platform identitical scrollbars and would help unifying designs.
I can't seem to get my second lightbox to launch into the lightbox. The first instance is fine and working perfectly. I'm assuming its some kind of code in the header to make it work but not sure at all.

I'm working on a component for Joomla in which I'm using jQuery. My problem is that when another component loads jQuery after mine, all plug-ins I'm using are being overwritten by the last jQuery initialization.
I have 2 possible solutions:
1. Load all add-ons on document ready or basically AFTER any jQuery initializations in the HEAD of the document
2. Rename the jQuery static object to something else (like myJQuery for example) and then extend it with the plugins.
The 2nd option somewhat guarantees me that my object will be properly initialized with all the code I need, but it mothers me that it may overload the browser in some way.
Trying to get this to work individually with each individual instance on the page (usually 5-10 questions on each page)Right now it adds the class to every instance of the div that has the answerCorrect class. need the link to only turn on the specific answer associated with it.
I'm just the jquery.media plugin. With multiple players being used for each mp3 link. Is there a way I can setup a jquery call that knows to pause (or stop) all other players once a user click on a new player?
There is this nice upload ajax script which I would like to use on my site, it's called "Fancy Upload". You can a see demo&code here:[URL]The demo shows only one upload form instance on the page. However I want to have three upload form instances so that the users can upload three pictures and see the thumbnails for each image they upload.The problem is, this javascript specifically sets the id's of the html fields in use. For instance, "demo-portrait" is the id of the image tag and it is also referred to within the javascript itself. So if I create another image field with an id "demo-portrait-2", the script wouldn't work for this second field.
I got a good book, and there are a lot of examples.
however, the author don't really explain how to use XMLHttpRequest in a real application, where the user will do several things at the same time.
my question is: for each request, you have to create a separate XMLHttpRequest, right?
because on the book they showed this code:
var xmlHttp;
function createXMLHttpRequest() {
if (window.XMLHttpRequest) { xmlHttp = new XMLHttpRequest(); }
else if (window.ActiveXObject) { xmlHttp = new ActiveXObject('Microsoft.XMLHTTP'); }
} // function createXMLHttpRequest and this is fine if on the page there is only one request, as they create a global var XMLHttpRequest.
However, I thought that it could happen that there are many requests at once (like if the user, while it's waiting for the first request to be completed, continues doing stuff, starting another request).
So, I changed it to this:
Code: function createXMLHttpRequest() {
var xmlHttp;
if (window.XMLHttpRequest) { xmlHttp = new XMLHttpRequest(); }
else if (window.ActiveXObject) { xmlHttp = new ActiveXObject('Microsoft.XMLHTTP'); }
return xmlHttp;
} // function createXMLHttpRequest and for each call I do:
Code: var xmlHttp1 = createXMLHttpRequest(); var xmlHttp2 = createXMLHttpRequest(); // etc...
