I have a list of questions and answers grouped in different divs. I would like to collapse them when a click event is fired that is placed on the question. I have read the examples from the Twitter Bootstrap page but I would like to tricker the event with Javascript and not with data-attributes. With data-attributes every question needs a unique id and this will hard to maintain in the future. I want to trigger the class ".collapse"

Try this example. You can always modify it according to the element being watched for click and the element to toggle.

You can use slideToggle() instead of toggle() to get the collapsing effect.

Something like this? Remember to include jQuery library
$('[data-toggle="collapse"]').on('click', function () {
$(this).closest('div.panel').find('.collapse').toggle('')
});

I am kinda new to Javascript/JQuery programming and I have a simple question.
What I am trying to accomplish is making a 450 x 350px popup that shows on a 2 second delay. I think I have the structure down on how to make it delay and show up.
My real question is how do I add custom content to that popup box? Would I add my content in a div with an ID and then reference that ID in the JQuery code to make it pop up?
I'm just not sure where to go with this.
Let me know!
Thanks.
Say you have a <div id="one" class="js-one"></div>. You can change text content w/ jQuery using the id $('#one').text("Hello") or the class $('.js-one').text("Hello"); note that using the class will update all elements w/ that class. If your custom content includes HTML then you'll want to use jQuery's html method instead of text.
See: http://api.jquery.com/text/ and the docs for .html()
To show/hide the styled div, see: http://api.jquery.com/toggle/ and the docs for .show() and .hide().
I'm currently designing a webpage presenting a twitter-like user input that generates an <li> (inside a <ul>) element in which are appended one <h6> element (the post's title) and a <p> element underneath (the content).This works, therefore the input and generation of elements is not the problem.
But what I want to do is use jQuery to hide the posts's content, and toggle it when I click on the post's title. The issue is that the event handler seems to work only for every second post. Whenever i post once more, the 1st post on the list can be toggled, the second not, third yes, etc.
From what I've seen in some answers, I've tried the .click() method, the .on() method, I've tried to replace .toggle() with.hide() and .show() under conditionals, then created a class with display:none to toggle on click. This was my last stop, and the result is described in the above paragraph. Here's the event handler:
$('.postinstance').on("click", "h6.postname", function() {
$(this).siblings().toggleClass('postOff');
});
The .siblings() is actually only the post content, but that's the only way I could get near what I wanted. When I replace $(this).siblings() with the actual class of the content element, every post's content toggles when I click on any title.
How can I make each post open individually when I click on it?
Here's a JSFiddle isolating the input & posts part.
I have looked thoroughly in Stack Overflow and other places, even tutorials, to solve this problem but although similar questions were found none of their answers provided a solution.
You should not attach event handlers to dynamically generated elements directly, instead use some common parent element. Here's a piece of your snippet where I changed the selector and everything started working:
$('.postlist').on("click", "h6.postname", function() {
$(this).siblings().toggleClass('postOff');
});
Important note: you must pull this piece of code out from $('.postbtn').click(..) one level up, otherwise for even number of posts toggling will not work!
And move this out of click handler:
$('.postlist').on("click", "h6.postname", function() {
console.log(this);
$(this).siblings().toggleClass('postOff');
});
Here is a link for a fiddle project I am working on right now. What I am trying to do is to switch active menu element depending on what section is displayed right now on screen. So if it is Kontakti on screen, then Kontakti in menu (<!--NAV BAR-->) has to display as active item. I am not familiar with jS
Add data-role=navigate attribute to ul element where navigation is housed,
In the javascript section of this fiddle,
please try with the following code,
$(function()
{
$("[data-role=navigate]").find("li > a").click(function()
{
$(this).parents("ul").find("li.active").removeClass("active");
$(this).parent().addClass("active");
})
})
I will explain in brief what the code does...
1) Binds a click event handler to <a> inside <li> which is inside <ul> with attribute data-role=navigate
2) When the click happens, it removes the active class for the current element.
3) Assigns the active class to the immediate parent of the <a>
It is a good practice to target specific needs in JS by placing attribute in the DOM elements and hooking up event listeners using that attribute.
Hope it helps!
Bootstrap's Affix might be something that could be useful in this case. It highlights what part of the page is displayed on the screen on a separate sub-navigation part of the page.
Btw, if you have Bootstrap code you can display it on Bootply quite easily. It provides Bootstrap's CSS and JavaScript files by default.
You say you're not familiar with JavaScript but you're asking for functionality that needs JavaScript. I'd recommend trying to use a plugin if it's not something you can write yourself.

I am trying to click on an image on my webpage and it open a new section on the page that would be created in css and javascript/jquery. I thought about using .addclass() but i am not entirely sure how to go about it. Can anyone give me an example of this being done?
An example by clicking on a element with the id foo and adding a div with the id bar after that element:
$("#foo").click(function(){
$(this).after('<div id="bar">Some content</div>');
});
Of course, there are multiple methods in jQuery which insert content somewhere in the DOM tree, see:
https://api.jquery.com/category/manipulation/dom-insertion-outside/
https://api.jquery.com/category/manipulation/dom-insertion-inside/
There are many ways to do it. As an example, you can simply attach a click event handler to your image, like so:
$('img').click(newSection);
function newSection() {
$('#someDiv').append('<div class="newSection"></div>');
}
I've wrote a function which is working fine and all but when I try to reuse it on multiple html blocks with the same class, it breaks. I've tried to use the .next() and .closest() method but without results. Where do I apply these? The function is to recreate a <select> dropdown but by using a unordered list.
It is important that the classes and function stay the same as the list is generated by the CMS and can be multiple times a page, so having a solution where I change the code and call each function separate is not good..
Demos
Dropdown works fine (function works fine on one unordered list)
Dropdown breaks (when reusing function and html code)
Your script had a number of things that needed changing. This should work, as best as I could understand what you were trying to do.
Main point being this:
$(".cloned").click(function(){
$('.options').toggle();
e.preventDefault();
});
The $('.options') selector inside the handler selects all the elements with the options class, regardless of where you clicked in the document. That's why every dropdown was activating on a click.
You should only select the specific .options element for the click. There are many ways to do this, but this is what I did:
$(this).next('.options').toggle();
This can be better.. Check out this fiddle
using toggleClass()
