GetElementById Alternative For Multiple Instances?

Apr 23, 2010

The code works, but it obviously can't be used for more than one picture per page because getElementById finds the first div and always displays it onmouseover of any attempted mouseover text.The Javascript in <head> is

<script type="text/javascript">
// Pop up code begin
function ShowPopup(hoveritem)

[code]....

So the display code is

<a id="hoverover" style="cursor:default;" onMouseOver="ShowPopup(this);" onMouseOut="HidePopup();">text here</a>
<div id="hoverpopup" style="visibility:hidden; position:absolute;"><img src="url here"></div>

I just want to be able to have more than one instance on each page and still be able to declare the image url in the body and not within the javascript.

Multiple Instances Of FancyUpload?

Aug 17, 2009

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.

Multiple Instances Of XMLHttpRequest

Jul 8, 2007

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...

is this the right way to go?

SetAttribute Multiple Instances

Nov 18, 2007

I know there is a problem with IE (I wont bother inserting a witty comment here) on handling:

setAttribute('onclick','doStuff');

I have found

yourAnchor.onclick = function() {
// do what you want in here.
}

this works, but I the script I am working on is going through every DIV with a certain class and adding links to the div, I want the button to change something within the div where it is located so I need to pass the id of the parent div. I thought perhaps there was someway to find the id of the button pressed?

JQuery :: Multiple Instances Of A Function?

Jul 31, 2009

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");

Consolidate Multiple Instances Of A Function

Apr 9, 2010

looking for a ways to consolidate multiple instances of a function... Here's the current one:

instance:

<div class="hex" onmouseover="onV('N03')">
<p id="Labbbab6">_ _</p>
<p id="Labbbab5">___</p>

[code]....

It could be done by changing the visibility of class"hN" from 'hidden' to 'visible'; and maybe it could be done by making class "hex" last-child visible.Whichever way, the function needs to be attached to the class.

Multiple Instances Of PhotoShuffler On Same Page?

I am using PhotoShuffler on my website for a slideshow. But, on my page, I want to have 2 slide shows going. But I can't seem to get it to work - I duplicated the JS code, and added the number "2" next to all the variables in the second file, to try and make it different, but it still will only fade one slide show, no both at the same time

Passing Vars/multiple Instances?

Aug 27, 2010

I'm building a comment system modeled after Tumblr's, where each post will have it's own comments. I've modded a system from 9lessons and am having an issue implementing it for multiple instances on a page. Each post has its own ID, so I'm trying to set this up using the post's ID. It works fine for a single post, but when there's more than one on a page it doesn't work.

Code Javascript:

JQuery :: Multiple Instances Of JTip Style?

Apr 6, 2011

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.

JQuery :: Have Multiple Instances Of Scroll-bar On Same Page?

Mar 18, 2007

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.

JQuery :: Multiple Instances Of Loading Plugins?

Sep 19, 2011

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.
