jQuery script works just for one button on the product catalog

I have a product catalog and I want to save on localstorage the products selected by the user.
The jquery script only gets the first product on each page on each click... it simply ignores the rest of the products, and the console prints the same object.
Here is my HTML+TWIG code
{% for products in pagination %}
<div class="product col-sm-6 col-lg-6 col-md-6 hero-feature">
<div id="{{attribute(products ,'id')}}" class="product thumbnail">
<img id="prodImage" class="img-responsive img-rounded" src="{{attribute(products ,'image')}}" style="width:150px;height:150px" >
<div class="product caption">
<h4 id="prodPrice" class="product pull-right"><b>{{ attribute (products, 'price') }}Lei</b></h4>
<h4 id="prodName" style="height:100px;width:200px;">
<a id="prodLink"
href="{{ attribute (products, 'affiliatelink') }}"
target="_blank">{{attribute ( products, 'name') }}</br></a>
</h4>
</div>
<div class="add-to-cart" class="product" >
<button id="buttonProd" class="oneButton btn btn-danger " value="Save" type="button">Adauga</button>
</div>
</div>
</div>
{% endfor %}
Here is the jquery script
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script type='text/javascript' defer="defer">
$(document).ready(function() {
var prodId = $('.thumbnail').attr("id");
$("#buttonProd").on("click", 'button', function(event){
event.preventDefault();
var products =
{
prodID :$('.thumbnail').attr("id"),
prodName :$('#prodName').text(),
prodPrice :$('#prodPrice').text(),
prodImage :$('#prodImage').attr('src'),
prodLink :$('#prodLink').attr('href')
};
localStorage.setItem('products-' + prodId, JSON.stringify(products));
var retrievedObject = JSON.parse(localStorage.getItem('products-' + prodId));
console.log('retrievedObject: ', retrievedObject);
});
});
</script>
How can I make the script take each product proprieties on click. Thank you in advance.

In JQuery, the assumption is made that all ID's will be unique. Since you're repeating "#buttonProd", JQuery will only select the first one to bind the action to. If you want to bind to multiple elements, you'll either have to give each button a unique ID or use some other selector to attach your jQuery functionality.
From the documentation for the ID Selector:
Calling jQuery() (or $()) with an id selector as its argument will return a jQuery object containing a collection of either zero or one DOM element.

As the other answers have eluded to you should be using a different selector. I recommend simply adding a descriptive class to each element you wish to grab data from.
<div class="products">
<div class="product">
<div class="productName">First Product</div>
<div class="productPrice">5.00</div>
</div>
<div class="product">
<div class="productName">Second Product</div>
<div class="productPrice">4.00</div>
</div>
<button id="buttonProduct">Log Product Info</button>
</div>
If you notice in the above HTML each div that contains a product's name or a product's price shares the same class productName and productPrice respectively. In addition each container class for each product has the same class as well: product.
This will allow us to utilize the JQuery class selector $(".") to iterate over each product container. We do this using the .each() function. We use the .find() function to locate productName and productPrice in each iteration of the loop.
$(document).ready(function() {
$("#buttonProduct").click(function(){
var products = [];
// Notice the dot in $(".product") that is the class selector
// the .each iterates over every element that matches the preceding selector
$(".product").each(function(){
products.push({
// The .find() selects an element inside $(this)
// that matches the parameter (either .productName or .productPrice
productName : $(this) .find('.productName').html(),
productPrice : $(this).find('.productPrice').html()
});
});
console.log(products);
});
});
For a working example of this check out this jsfiddle. (I noticed you had console.log() in your code so that's where I output the result.)

You want to save the product in localStorage on clicking of corresponding button right?
for that instead of binding click event via jquery, put it in html and move the click code to a function saveProduct()
HTML:
<button id="buttonProd" class="oneButton btn btn-danger " value="Save" type="button" onclick="saveProduct({{attribute(products ,'id')}})">Adauga</button>
JS:
function saveProduct(event, prod_id){
event.preventDefault();
var products =
{
prodID :prod_id,
prodName :$('#'+prod_id+' #prodName').text(),
prodPrice :$('#'+prod_id+' #prodPrice').text(),
prodImage :$('#'+prod_id+' #prodImage').attr('src'),
prodLink :$('#'+prod_id+' #prodLink').attr('href')
};
localStorage.setItem('products-' + prod_id, JSON.stringify(products));
var retrievedObject = JSON.parse(localStorage.getItem('products-' + prod_id));
console.log('retrievedObject: ', retrievedObject);
});
}

You need to change #buttonProd from an id to a class. An id is only supposed to appear once on a page, so jQuery will only apply it to one. Change it to a class in your markup and your script and it should work fine. Same for prodName, prodPrice, prodImage, and prodLink. Anything that will be going inside the loop needs to be a class, and any id should be unique, like you have {{attribute(products ,'id')}}

Show Bootstrap tab loaded using Ajax doesn't work the first time it's clicked

I'm trying to load the content of a given tab using Ajax.
The first tab I render on the server as being active, and the others I active and load using Ajax.
I've isolated the problem (without Ajax) here.
HTML:
<h1>Hello, tabs!</h1>
<div>
<ul class="nav nav-tabs" role="tablist">
<li role="presentation" class="active">Home
</li>
<li role="presentation">Profile
</li>
<li role="presentation">Messages
</li>
<li role="presentation">Settings
</li>
</ul>
<div class="tab-content">
<div role="tabpanel" class="tab-pane active" id="home">...</div>
</div>
</div>
Javascript:
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
e.preventDefault();
var ref = $(this).attr('href').replace('#', '');
var html = '<div role="tabpanel" class="tab-pane" id="' + ref + '">Brace yourself SW7 is coming. ' + ref + '</div>';
var tabContent = $('.tab-content');
if (!tabContent.find('.tab-pane#' + ref).length) {
tabContent.append(html);
}
tabContent.find('.tab-pane#' + ref).tab('show');
});
The Home tab is rendered already activated.
Click in the Profile tab for example, it will append the content but won't activate the tab. Now, if you click in the Home tab and in the Profile tab again, it'll work correctly.
I'm doing something wrong or this is an 'expected' behavior?

The problem is that the content DIVs don't exist the first time you click on a tab, so when the Bootstrap code executes it doesn't find the DIV it needs to activate. The second time you click, the DIV exists, so Bootstrap finds it. You can get around this by hiding all of the tab content DIVs at the end of the script, and then showing the one that was specified.
$('a[data-toggle="tab"]').on('shown.bs.tab', function (e) {
e.preventDefault();
var ref = $(this).attr('href').replace('#', '');
var tabContent = $('.tab-content');
if (!$('#' + ref).length) {
// Execute the AJAX here to get the tab content
var html = '<div role="tabpanel" class="tab-pane" id="' + ref + '">Brace yourself SW7 is coming. ' + ref + '</div>';
tabContent.append(html);
}
tabContent.find('.tab-pane').hide();
tabContent.find('#' + ref).show();
});
I believe this could be further optimized, but I'm out of time right now and this works...

What was happening was as you said, the following:
The ajax request was created, and the click handler for the tab was also fired.
The handler was executed while there's no target content to be shown but it added the 'active' class to the 'li' element.
When the ajax request was completed I executed the "tab('show')" code but as the 'li' tab was already activated the event was not handled properly.
The said line is this:
https://github.com/twbs/bootstrap/blob/master/dist/js/bootstrap.js#L2081
Adding removeClass before the execution of the tab show worked:
el.parent().removeClass('active');
el.tab('show');
Where el is the 'a' element.

I solved just
$('#mydivid').addClass('show');

how to change values in a hidden chunk of html code

I have this hidden block of code that i want to call based on the values that are received from server:
<div id="hiddenChart" style="display:none;">
<li style="height:auto;">
<div class="col-sm-4" id="chart_0_0">
<div class="panel panel-success" style="width:550px; height:auto;" id="accordion_0_0">
<div class="panel-heading">
<div class="btn-group" style="float:right;">
<i class="glyphicon glyphicon-minus" id="minimize_0_0"></i>
<i class="glyphicon glyphicon-remove" id="close_0_0"></i>
</div>
<h3 class="panel-title">title</h3>
</div>
<div class="panel-body" style="height:400px;">
<nvd3-multi-bar-chart data="Sec1Graf1Data" id="dataChart_0_0" height="400" showXAxis="true" reduceXTicks="true" showYAxis="true" showLegend="true" showControls="true" tooltips="true">
<svg></svg>
</nvd3-multi-bar-chart>
</div>
</div>
</div>
</li>
</div>
but i need to change some values: ids, tags, data variables.
I know how to show the code using "$('ul').append($('div').html());" but i have to change it before doing it.
How can i do it?
How do i define in which fields i have to insert the string i'me receiving?
Thk
UPDATE:
I was able put it to work, here is the fiddle with it fiddle.
When i inspect the element, the ids that i want to change, instead of #1, it returns chart_0_0.
Thank you all for your posts and help

You can get a reference to your div like this:
var $div = $('#hiddenChart');
To clone it,
var $clonedDiv = $div.clone();
Then, in the $cloneDiv object, you make the changes:
$clonedDiv.find(--selector of a node--).attr(atributeName, atributeValue); //change/add attribute
$clonedDiv.find(--selector of a node--).removeAttr(atributeName); //remove attribute
And so on. I won't explain how jQuery works, Lekhnath gave you a link.
Finally you insert the $clonedDiv with .appendTo() wherever you want. The original div remains untouched so you can clone it again and again.

Jquery Change text/html from a hidden div content :
Simple
maintain a copy of the hidden content
replace the content based on the element class/id selector with the server response
then paste the html into another div
replace the content of the hidden back to original (optional)
http://jsfiddle.net/austinnoronha/ZJ3Nt/
$(document).ready(function(){
var serverRes = {
title: "New Title In Header",
body: "New body text from server <\/br><nvd3-multi-bar-chart data=\"Sec1Graf1Data\" id=\"dataChart_0_0\" height=\"400\" showXAxis=\"true\" reduceXTicks=\"true\" showYAxis=\"true\" showLegend=\"true\" showControls=\"true\" tooltips=\"true\"><svg><\/svg><\/nvd3-multi-bar-chart>"
};
var tmpOldCont = $("#hiddenChart").html();
var counter = 1;
$(".serverres").click(function(){
$("#hiddenChart").find(".panel-body").html(counter + " = " + serverRes.body);
$("#hiddenChart").find(".panel-title").text(serverRes.title + " " + counter);
counter++;
$(".box-container").html($("#hiddenChart").html());
$("#hiddenChart").html(tmpOldCont);
});
});

Running click functions on every instance of listing instead of current

I have a listing of articles here, and I can't figure out how to execute the ng-click function calls on every new article inside the ng-repeat. Right now it works for existing articles, but when new articles are added dynamically (via AJAX), I need those to have the same functionality too.
For example: the ng-click function calls on the "+" sign to reveal social buttons seem to not work once new articles are inserted via AJAX (ie: delete articles, and let list be populated again with new elements)
Does AngularJS provide any tools to do that?
<div>
<div>
<input type="text" ng-model="search">
<span>{{filtered.length}} article(s)</span>
</div>
<div article-listing ng-repeat="article in filtered = (wikiArticles | filter:search)">
<!--Individual article begin-->
<span>
{{article.title}}
</span>
<div>
<a ng-click="articles.removeArticle($index)" title="Delete">
<span>✖</span>
</a>
<a ng-click="articles.toggleShare(article)">
<span class="plus-sign" title="Share">✖</span>
<div social-share ng-show="article.socialShare">
<div ng-click="socialShare = !socialShare" class="addthis_toolbox addthis_default_style addthis_32x32_style"
addthis:title="{{article.title}}" addthis:description="{{article.extract}}" addthis:url="{{article.url}}">
<a class="addthis_button_facebook"></a>
<a class="addthis_button_twitter"></a>
<a class="addthis_button_google_plusone_share"></a>
<a class="addthis_button_reddit"></a>
<a class="addthis_button_hackernews"></a>
</div>
</div>
</a>
</div>
<div>{{article.extract}}</div>
<!--Individual article end-->
</div>
</div>
Code for ng-click calls that don't seem to work for new article insertions
$scope.articles = (function() {
return {
shuffleArticles : function() {
$scope.wikiArticles.reverse();
},
removeArticle : function(index) {
$scope.wikiArticles.splice(index, 1);
$scope.fireAPICalls();
},
toggleShare : function(currArticle) {
var previousState = currArticle.socialShare;
angular.forEach($scope.wikiArticles, function(article) {
article.socialShare = false;
});
currArticle.socialShare = previousState ? false : true;
}
}
})();

Your ng-click calls are actually working- you can watch the ng-show toggle in the debugger.
The problem is that there is nothing to display on the new items you add.
The articles you initially add all have their icons populated with the .addthis classes, for instance here's your Facebook icon element:
<a class="addthis_button_facebook at300b" title="Facebook" href="#">
<span class=" at300bs at15nc at15t_facebook">
<span class="at_a11y">Share on facebook</span>
</span>
</a>
at300bs includes the following css which displays the image:
background: url(widget058_32x32.gif) no-repeat left!important;
However as you add new items, you aren't including the needed .addthis classes to them. Their elements look like this:
<a class="addthis_button_facebook"></a>
So ng-show has nothing to display (it shows a 0x0 div).
Add the .addthis classes to your new elements as you add them and you'll be all set.

Isotope hide on click

My site has all elements displayed by default.
Isotope has the inbuilt method 'filter' - ie show ONLY this.
I'd like to make a function where I hide/show an element based on clicking on a button on screen - ie hide ONLY this (and show the others) / unhide this (and show the others).
Here's what I'm doing code-wise.
var music = $('#music').isotope();
$('nav button').on('click', function () {
music.isotope({
filter: "div." + $(this).attr("class")
});

With filtering, the filter parameter must match items in your HTML markup, if not the filter will not return anything.
FIDDLE DEMO: http://jsfiddle.net/XWVhc/1/
I can only provide an alternate example as you have not provided any html markup so that we could debug your current code, however, I'll explain how this works.
HTML FOR FILTERS:
Here we have a few simple buttons that will filter our items with the data-filter attribute attached to each button.
<div id="filter-buttons-holder">
<div class="filter-button" data-filter=".dog">DOG</div>
<div class="filter-button" data-filter=".cat">CAT</div>
<div class="filter-button" data-filter=".foo">FOO</div>
<div class="filter-button" data-filter=".bar">BAR</div>
<div class="filter-button selected" data-filter=".dog, .foo, .cat, .bar">SHOW ALL</div>
</div>
HTML FOR ISOTOPE ITEMS:
Here's the markup for our isotope items, notice that each item has a class of isotope-item and also has a class of what 'category' it belongs too, you can add multiple classes and it will still filter as expected.
<div id="module-columns-holder" class="isotope">
<a href="/" class="dog isotope-item">
<div><h1>DOG</h1></div>
</a>
<a href="/" class="cat foo isotope-item">
<div><h1>CAT</h1></div>
</a>
<a href="/" class="dog isotope-item">
<div><h1>DOG</h1></div>
</a>
<a href="/" class="foo isotope-item">
<div><h1>FOO</h1></div>
</a>
<a href="/" class="bar isotope-item">
<div><h1>BAR</h1></div>
</a>
</div>
JAVASCRIPT FILTERING
Here we set up our isotope container, notice the last data attribute is a filter, this is effectively what you're after, however you can specify which 'category' you want to filter on initially.
//Setup isotope for filters
var isotopeContainer = $('#module-columns-holder');
isotopeContainer.isotope({
itemSelector: '.isotope-item',
layoutMode : 'fitRows',
animationOptions : {
queue : false,
duration : 750,
easing: 'linear'
},
filter: '.dog, .cat, .foo, .bar'
});
CLICK EVENT FOR FILTERS
You can attach a filter to the buttons we created earlier so that you can have live filtering
$('#filter-buttons-holder .filter-button').on('click',function(){
var filters = $(this).data('filter');
var parent = $(this).closest('#filter-buttons-holder');
parent.find('.selected').removeClass('selected');
$(this).addClass('selected');
isotopeContainer.isotope({ filter: filters });
return false;
});
Hope this helps
