I figure this is a JS question. I wonder if anyone has any thoughts on methods of preloading hidden content. For example, lets say you have a drop down menu or something similar, which contains images for bullets or borders, whatever the case. These items are hidden via css, and therefore would not be loaded until they are rolled over or clicked. This usually creates and ugly effect the first time, as the popup/drop down will show, then it will take a second for the image to load.
The problems im facing is when I use something like jcarousellite inside tabs. It works fine in browsers other than ie. In ie, the carousel loads fine in the active tab, but in the inactive ones it doesnt preload.
Basically when you click on a previously inactive tab, it displays nothing until you click outside the tab.
I have narrowed down the problem to this: My tabs use a css style where the inactive tabs set the display to none. This somehow in ie causes whatever jquery that is contained within not to load before hand. If I remove this display: none property, all my carousels show fine, but ofcourse so do all the tabs
i.e. they are no longer hidden when inactive, instead all are shown as overlapping blocks on the page.
Note: all elements used are div elements

I have also posted this question on StackOverflow which you can see here. This first issue I had to solve was using jQuery in an ASPP.Net app with Master Content pages - that issue is resolved. The main issue is that I have a content page that has many divs on it - 3 of which are hidden when the page first loads and are then each displayed based on various user interaction wth the page. One of the divs is displayed by server side code for many reasons dvDetail.style("displaya') = "block". My issue is that I need to use jQuery on an element that is located inside this div and can't seem to get that to work. The jQuery works just fine on anything that is not inside the hidden div. Items to note: Hiding and displaying the hidden divs works just fine. I am not using the visible property on any div - I use the display = "block" and 'none' in both the client side code and the server side code. jQuery working just fine on the page - just not on elements inside the hidden div. jQuery selectors working just fine in the content page scenario just not in the hidden div.
How do I get the elements from a form when these elements are named like each other? I'd like to make a list of values and store it in few hidden elements. It is suppose to work like a list of checkbox whose elements have the same name (and same id), but they are diferent indexed. [code]...
I am trying to make a carousel of sorts. I am kind of stuck with hiding and displaying the next and precious buttons once a div moves to the far left and right of its container. I think i have everything correct regarding calculating the widths but for some reason when you click the buttons, elements stay hidden irrespective of the conditional comments which should dictate when they should be hidden or shown. Here is a link to what i have thus far. Click the MoveLeft and MoveRight buttons. [URL]
I have done the hide/show divs using javascript.Its working fine but the problem is that at the time of page loading the hidden divs are showing first anf then disappearing.Is there any way not to show the hidden elements even if the page loads for first time
I have a page that opens up an iframe for the user to be able to select photos. Each photo has a checkbox, and on select I add a hidden form element to the parent frame form. This all seems to work fine, but im now stuck on how to remove the form element when the checkbox is un-checked.
I have a webpage which the user can drag a marker around inside a div and the script then shows the standard js alert box with the final positions of the marker once the user has stopped dragging it about. What I need to do is get the script to add these values to two hidden input elements in the page.
'When my form is submitted, I have onsubmit pointed to the following code snippet. But, the button is not actually set to disabled and the style.visibility changes are not made for several seconds. It appears that it goes into validateForm and doing the rest of this snippet before the browser makes the changes.
How can I get the browser to immediately make the UI change?
function submitForm(servleturl) { var submitbuttonelem = document.getElementById("submit"); submitbuttonelem.disabled = true; document.getElementById("modgradeform").style.visibility="hidden"; var mydiv = document.getElementById("contentarea"); mydiv.innerHTML = "Validating the form."; mydiv.style.visibility="visible"; var ret = validateForm();
i am working on a custom drop down list that has hidden #options DIV which is shown when the user clicks on a button. the problem i am having is that the click event does not seem to be attached to the LI elements since they are hidden when the page first loads. if i show the #options DIV when the page loads everything is working as expected.i've tried to attach the click event after i show the hidden UL but that didn't work either.what can i do to make sure the LI click event fires? i tried to put A tag inside of LI and attach click to that but to no avail.
Does "document.formName.elementName.disable" work on hidden form text elements? I have a form with some input fields that are associated with some hidden text fields and I would like to disable all of the categories inside the form when the page loads and only enable each category as it is needed. Code:
Given the following input tag which is enclosed within a hidden div tag:<input id="X" class="Y"/> this call (id-based) locates the tag: $(this).find("#X")but this one doesn't (class-based)I couldn't find any documentation indicating find() working differently when using id-based vs class-based selectors.
I have a section of a form containing elements that are not visible, currently just in a hidden div. Some of these elements have validation on them so when the form is submitted it fails on this validation.What I am after is a way to stop the validation firing for any hidden elements. I have tried setting them to 'display: none' and 'visibility: hidden' but this does not have any affect.
I am trying to get a simple set of Javascript tabs to work properly. I have just two tabs and I want to set up the script to have the second tab automatically hidden prior to reading the javascript code because right now it shows the contents of both tabs when the page is loading and then the second tab disappears after all the script has loaded.
I have the jquery script linked to on the page and here is the way my script looks to run the tabs:
Code:
I want to add something like style="visibility:hidden;" to the DIV that isn't shown on page load and have it added and removed as necessary when users click on the tabs. So basically I would like the generated code to look like this:
Specifically, assume I have a div tag of absolute dimensions. I need to figure out, first, whether or not the text inside the div tag is partially hidden by the overflow setting, and if so, what the hidden text is.
Is this even possible? Obviously, the rendering engine in the browser "knows" this information, but is it accessible through Javascript?
I have tried several preload scripts found here; plus, some of my own. The only thing that works is the unsophisticated loading of those tiny images. The download consist of 100+ images amounting to 50+mb; and, normally completes in less than 1 minute without preload (using DSL).
The preload terminates after 6 or 7 images and seems to time-out in the middle of an image. A reload will download a few more, etc. I have used the <body onLoad=function()> approach as well as the non-function approach of JS that executes immediately with the page's loading. Getting the same results with Netscape-7 and IE-6.
I need to add: The source of the array containing the image references is a '.js' file. That doesn't seem pertinent as some of the images always load.
I´m using dreamweaver´s built in preloader for a menu. it looks like this:
function MM_preloadImages() { //v3.0 var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array(); var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++) if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
Has anyone else had this issue? Basically, the preload of images for a rollover effect for the navigation is really really slow when using IE 6.0 but when i view the site using Netscape, it's fast like it should be(no lag!)
My problem is that since 96% of users use IE, i need to figure a way to fix this. Below is the javascript currently being used. The arguments are passed in before the script is called.
function gn_rollover_preload(){ //preloads middle images for the navigation if (document.images){ var argLength = gn_rollover_preload.arguments.length;
for (arg=0; arg < argLength; arg++){ eval(arguments[arg] + "_off = new Image()"); eval(arguments[arg] + "_on = new Image()"); eval(arguments[arg] + "_left = new Image()"); eval(arguments[arg] + "_right = new Image()");
// Now Preload all "corner" images for faster swapping corner1 = new Image(); corner2 = new Image(); corner2_both = new Image(); corner3 = new Image(); corner3_both = new Image(); corner4 = new Image(); corner4_both = new Image(); corner5 = new Image();
Want to know if there is a way to preload a song before the slide show starts. Also, would like to be able to show the lyrics 2 paragraphs at a time, timed with the singer so viewers don't have to scroll to see the lyrics. The lyrics are currently just in a table row with the <td> tag. I would have to have a timer start with the execution of the song, and replace the lyric text as the singer completes each verse.
Or, can you link the photo image with the scroll bar so if they scroll, photo will scroll so they can still see it as they view the lyrics.
I really have little idea of what I am doing, and have gotten to where I am by lifting various scripts off the Internet. Any help would be greatly appreciated. Please keep in mind I am a web designer IDIOT.
