Bootstrap collapse without unique identifier - javascript

I'm trying to use the bootstrap collapse plugin in such a way that a unique identifier is not required. Normally there is usually a single or a couple of collapsible elements on a page.
But my elements are generated dynamically and passing index keys is overkill.
What happens now is that if I toggle the collapse for element2, it will collapse element1. Obviously because they have the same ID.
Any way to achieve this without actually giving each collapsible element a unique id?
Here's a functional js fiddle:
http://jsfiddle.net/hhvrjnr3/

It can be done. First remove the data-target="#collapseExample" from the elements you want to collapse. Then add an extra class to your toggle button, I've added 'collapser'. That's not really needed, but it's nice to identify the toggle button. Then add some jQuery to do the toggling, in this case I am using next() to get the subsequent element to the toggle button which is your element you wish to collapse.
$('.collapser').click(function() {
$(this).next().collapse('toggle');
});

Bootstrap collapse section and expand another with one button

I have a bunch of HTML fields logically separated as such: half the fields reside in: div id="general" and the other half reside in: div id="advanced"
What I'm trying to implement (and failing) is the following:
The fields in the general div to be shown (by default). A button with the caption "Advanced" shown. And the fields in the advanced div to be hidden.
When this button is clicked, the following should occur:
General section collapses hiding all it's fields
Advanced section expands showing all it's fields
Button caption is changed to "General".
Subsequent clicks toggles the above.
E.g. upon the next click, the advanced section now is hidden, general section now is shown, and button caption changes to "Advanced"
Notes: This seems trivial but being new to web front-end, I can't get this easily. If my div section is incorrect, then scrap it. I suspect I'm on the right track, and just need some jQuery code to collapse and expand divs.
Below are my attempts:
I used the Bootstrap collapse plugin with accordian markup, but this isn't what I want. It comes close though, but each section has a heading/button. I'd like one heading/button to toggle each section in an opposite manner.
I used the Bootstrap collapse plugin without the accordian markup, but same result as attempt 1 - two button again.
I tried using jQuery to do this dynamically, but can't get the logic (or syntax) correct.
I'm using Bootstrap, but happy to go with jQuery (or JavaScript) solution if it can't be done solely in Bootstrap with the collapse plugin.
You can do it using jquery by toggling a class on element which decides which fields to be shown.
for e.g. Take an outer div, and put general and advanced div inside outer div and show only the fields based on outer div class like advanced using css. And bind a button to toggle the class on the outer div.
Checkout JSFiddle here : http://jsfiddle.net/eqhw2mxx/2/
Check the JSFiddle :- JSFiddle
$("#advanced").addClass('hide');
$(".button").click(function(){
$("#advanced").toggleClass('hide');
$("#general").toggleClass('hide');
if($(this).attr("value") == "Advanced"){
$(this).attr("value","General");
}
else if($(this).attr("value") == "General"){
$(this).attr("value","Advanced");
}
});

need to empty a div but keep only a few div's inside the div but retain there jquery click functionality

I have a div which I need to empty excluding a couple of divs inside it, the problem is, I have got it to work but the div's lose there jquery click functionality.
I have a stage which will have items dragged on them but I need to be able to empty these items but retain the click buttons which are also on the stage and stored in a div called keep.
I found this and it works but the things inside #keep still appear but they lose their jquery .click().
var $stage = $('#stage'), $noRemove = $stage.find('#keep');
$stage.html($noRemove);
This is because they are being removed and then re-added.
You either have to remove the children. OR Rebind the click method afterwards.
So for example:
$noRemove.click(function(...){});
See the Fiddle here : http://jsfiddle.net/r98dj/1/
Also, as a note. Make keep a class. Otherwise you'll end up with multiple divs with the same ID and this will cause you to fail W3C validation.

Clickable Div - Wrap anchor link or use JS?

I have a reasonably complex list of Dynamic Div classes which contain various nexted divs to display shop content - the whole thing needs to have a hover state and be clickable (it currently has hover styles applied) and accessible.
I figure I can either approach this by -
1 - Make the containing Div into an Anchor link and style accordingly
2 - Nest an anchor tag within the div class and write a JS function to trigger a click on the anchor when the containing div is clicked.
Whats the thoughts on which is the correct approach?
I would definitely go with the wrapping <a> in that case you don't have to think about setting tabIndex=0, role=link and also you can skip adding the extra JavaScript to make the button clickable and binding the enter key for the same action as well.
Or if the "link" is not taking the user to another location and just show a modal window or some other fancy function you should wrap the <div> with a <button> in that case you can also skip binding the spacebar to the action too, as it is inherited. (But if you really can't do that you should add role=button to the wrapping <a>)
Now you can focus on styling and remember to use both :hover and :focus
It's fine to make the <div> clickable by adding an "onclick" handler. However, you should specify an ARIA "role" attribute (such as role="button" or role="link") as well as specify the "tabindex" attribute (tabindex="0") to make it possible to bring the element into focus when using the tab button on the keyboard.

add div from drop down menu selection jquery

I am able to add a row with the dom but how can I get a div to display to the right of drop down depending on what is selected?
Here is an example of what I have so far: http://jsbin.com/#/afojid/1/edit
The first drop down is working correctly but the rest I would like to add when the button is clicked and I would like them to work the same way as the orginal drop down menu. So that if Asian is selected an add section will appear to the right, if Other is selected an other add section will appear to the right, and so on for each time the add button is clicked. I tried clone but I don't want anything to be selected when the add button is clicked
The fact that you're working with ids instead of classes more or less universally makes this very challenging. You should update your code to work with classes and appropriately clone the *Info tables when you create new dropdowns.
You're using an old version of jQuery, so .on is not available to you for delegation. Instead, use .delegate:
$(document).delegate('#typeofEthnicity,[id^=newDDMenu]', 'change', showEthnicity)
This will call the showEthnicity function for the original dropdown and any added dropdowns, but you also have to clone all of the *Info divs and put them in the appropriate spot in the table (I suppose the same spot as the appended row). If you use classes, then it's a simple matter of finding the dropdown's parent row and then locating the corresponding child with the appropriate class to be shown.

Creating mobile jQuery Toggle menu

I'm trying to make an jQuery toggle menu for a mobile website.
Since it is a wordpress site I would like to make this as dynamic as possible. I want to create a custom WordPress menu.
Now the tricky part comes.
I want it to check if the menu item has children (or child ul) and then toggle between:
<div class="plus">+</div> and <div class="min">-</div>.
When a item has no childeren nothing should happen at all.
So far I've managed to do this, please see my experiment at http://jsfiddle.net/jfvandekamp/9Dvrr/2/
You can use the jQuery function $.contains() to Check to see if a DOM element is within another DOM element.
http://api.jquery.com/jQuery.contains/
So in your example, you'd check to see if the menu item that was clicked contains another UL element
$jQuery.contains($(this), '<ul>');
I would use $.has() to filter out the collapsible items.
I've updated your jsFiddle: http://jsfiddle.net/9Dvrr/5/
