So my scenario goes like this:
I have 3 kind on item to show in div. There are three buttons on top of div and when user click any of the button items corresponding to that items are shown.
Items comes from backend and I am getting all the items loaded on page load as I also need them some where else also within same context.
Currently I am following show hide approach for the same .What I want to know is can there be any other approach that can be better then this in terms of code optimisation. User can also edit /add./remove item?
Here is my fiddle
$(document).ready(function(){
console.log($('.toggleItems'));
$('.toggleItems').click(function(){
$('.containers').hide();
var identifier = $(this).data('identifier');
console.log(identifier);
$('#'+identifier).show();
});
})
First order by items then use accordion jquery

I have a javascript file that when called, checks to see if a particular option is selected on a form. The form allows for multiple selections before being submitted. When a particular item is selected within the given choices it shows a hidden menu. In this case with "audits" I am able to show the hidden menu fine when just "audits" is selected from the list. However, I'm having much difficulty in figuring out how to get the menu to show when "audits" would be selected/highlighted with others. Eg: I had audits, services, someotheroption
Below you can see the code I'm currently using and that's working only when the single item is selected. Any guidance would be much appreciated.
function toggleFields(){
function toggleFields(){
if ($("#installations").val() == "audits"){
$("#dbcredentialsfield").show();
}
else
$("#dbcredentialsfield").hide();
}
Using the code you have so far, I assume you probably want something like this:
$('#installations').on('change', function(){
$("#dbcredentialsfield").toggle($(this).val() == 'audits');
});
This says; when the select element (assuming your dropdown has the id of installations) changes, toggle the visibility of the element with id dbcredentialsfield depending on if the value of the select is audits or not.
Say I have a left-side chat bar with chat users. Each user has their image (much like Facebook's chat)and is clickable to open a chat box to start chatting away.
Here's my code:
$('.msg_wrap').hide();
$('.msg_box').hide();
$('.chat_user').click(function() {
$('.msg_wrap').show();
$('.msg_box').show();
}
I know this is wrong but what I want to do here is when the page loads for the first time, all the chatboxes to be hidden (hide ()). It is not until I click on a chat user (.chat_user) that a pop up/chat box appears (show()). How do I fix this code? Do I have to create a function?
A quick thought on a solution.
First. Set the elements ('.msg_wrap') and ('.msg_box') to hidden in your html and kill your first two lines of code. I am not sure what those elements specifically are, but, for example, if they were div tags it would look something like:
<div hidden class="msg_wrap">
Second. I am not sure if you are saying that the code currently isn't working on page load. It looks like you are missing a ) at the end and also you can update to the following so that it gets executed on page load.
$(function(){
$('.chat_user').click(function() {
$('.msg_wrap').show();
$('.msg_box').show();
});
});
This is jquery shorthand for $( document ).ready().
Also, if you want the msg_wrap and msg_box elements to toggle between being hidden and shown you can use the toggle() method instead of show().
I'm using the 0.3 version of the jQuery jCarousel script to display three carousels on the webpage I'm working on. Those three carousels work just fine.
The trouble is : you can't use them properly using the keyboard.
If you tab through the page, the focus goes to the first link of the first item in the carousel, even if this item is not visible ! (For example : click on a "next" link in one of the carousels, then use the tab key to browse : the focus will go to a link which is not visible inside of the carousel).
If you keep using the "tab" key, the focus will successively go to all the links of all the items in the carousel.
Instead of that : the focus should go to the first link of the first visible item ; then, if the last link of the last visible item is reached, then the focus should go out of the carousel (the next link outside of it, in fact).
A solution could be to use tabindex... but some parts of the page are shared with other pages of the website, so I just can't use tabindex in all the links of all my pages...
Instead of that, I had tried things like this :
$("#carousel-editos li a").focusin(function () {
$("#carousel-editos li.jcarousel-item-first .post-title a").focus();
return false;
});
but then it prevents any further use of the "tab" key...
I hope this is clear... Thanx for any help !
I think you need a combination of the answers that you've already provided. It seems like you should be able to use Javascript to dynamically set tabindex attributes on the HTML that you need to be tabbable (heh, new word). I'm thinking of something like this:
On page load, find all visible items in the carousel. Use jQuery to set the tabindex property for each item that you want in the tab cycle.
Assign tabindex properties to all other links on the page that you want to cycle through.
Add some jQuery to modify the tabindex attributes when the user changes the items in the carousel (click the next/prev buttons).
It would be much easier to help you if you made a simplified example in jsFiddle.
On the carousel createEnd and scrollEnd functions you can reset the contents of .jCarousel so that only the visible carousel items are "tabbable". I have done that in my code as follows:
var bannerSlider_scrollEnd = function(event, carousel) {
var $carousel = carousel.element(),
$items = carousel.items(),
$bannerContent,
$visibleItemsContent = carousel.visible().find('.bannerContent');
$items.each(function (index) {
$bannerContent = $(this).find('.bannerContent');
disableTabbing($bannerContent);
});
reenableTabbing($visibleItemsContent);
$visibleItemsContent.find(':focusable').eq(0).focus();
};
The disableTabbing($container) and reenableTabbing($container) lines refer to helper functions I coded into my site which basically find all :focusable elements in a given container and set the tabindex to "-1", then "0" respectively.
After this processes, users will be left tabbing only through visible carousel items instead of all carousel items.
I have some weird behavior with jQuery paginate plug-in (jPaginate). I need to have top and bottom pagination and I want to sync them - whenever one is clicked, the second one should be properly changed as well.
I have two divs with number_pagination class and they are initialized the same way:
$(".number_pagination").paginate(options);
Now, here where it gets weird. Whenever I click on the top div, everything works as supposed to, but if I click on the bottom one, it changes the bottom one and does the pagination, but the top one stays the same. I cannot figure out why that could be happening.
Here's the onChange function that is supposed to change both pagination divs. Note the jQuery.fn.draw function that is a part of jPaginate. This is where it applies classes and style.
var opts=jQuery.extend({},jQuery.fn.paginate.defaults,options);
var o=jQuery.meta?jQuery.extend({},opts,jQuery(this).data()):opts;
jQuery(".number_pagination").each(function(){
var obj=jQuery(this);
jQuery.fn.draw(o,obj,page);
});
Found another solution that works perfectly.
It may even work for other pagination plug-ins. It checks the class that has the currently selected page number and checks if the content matches the selected NOW page, and if it doesn't, it looks for siblings that have the correctly selected page and triggers the click event.
jQuery(".jPag-current").each(function(){
if(jQuery(this).html() != page){
jQuery(this).parent().siblings().children().each(function(){
if(jQuery(this).html() == page){
jQuery(this).trigger("click");
}
});
}
});
You should probably look at using the onChange event to redraw the other pager that didn't incur the change
I have an unordered list where I hide any additional list items if more than 3. After that I invoke a JQuery function that puts in a "show more" link at the bottom and toggles any additional list items to show.
However, I'm a bit stuck, I'd like to convert the show link to "Hide" once all list items are showing and clicking on that then hides the additional list items and then the link changes back to "Show more..." again.
Here is the code I have so far that works to expand and show the additional list items.
$('ul li:gt('+index+')').hide();
$('ul').append('<li class="more">Show more...</li>');
$('ul li.more a').click(function() {
$('ul li.more a').remove();
$('ul li:gt('+index+')').show();
});
Note I am not stuck on this code, if there is a better way do implement the entire show / hide code, that's fine.
I wrote a fiddle with the code I have so far.
Here jquery toggle() function comes in handy - you can attach to event handlers that will be called every other time element is clicked. Use text() to change text of the link (which should't be a link if you don't plan a fallback - use span instead)
Updated fiddle.
There you go sir :)
Fixed and running well!
