I'm trying to pass data from a function to a specific div, but I can't seem to be able to get this to work. I'm making a gallery viewer and I just want to pass the counter that I use to show the pictures and the total number of files for each gallery in the page.
Here is the code:
jQuery
$(document).ready(function () {
$('.photoset').each(function () {
$(this).data('counter', 0);
$items = $(this).find('img')
$(this).data('numItems', $items.length);
});
var showCurrent = function (photoset) {
$items = photoset.find('img');
var counter = photoset.data('counter');
var numItems = $items.length;
var itemToShow = Math.abs(counter % numItems);
$items.fadeOut();
$items.eq(itemToShow).fadeIn();
};
$('.photoset').on('click', function (e) {
e.stopPropagation();
var photoset = $(this);
var pWidth = photoset.innerWidth();
var pOffset = photoset.offset();
var x = e.pageX - pOffset.left;
if (pWidth / 2 > x) {
photoset.data('counter', photoset.data('counter') - 1);
if (photoset.data('counter') < 0)
photoset.data('counter', photoset.data('numItems') - 1);
showCurrent(photoset);
} else {
photoset.data('counter', photoset.data('counter') + 1);
if (photoset.data('counter') > photoset.data('numItems') - 1)
photoset.data('counter', 0);
showCurrent(photoset);
}
$(this).text(photoset.data('counter') + 1 + " de " + photoset.data('numItems'))
});
});
Html Razor
<div class="container">
#{ var i = 10; }
#foreach (var item in Model)
{
<div class="row">
<div class="col-md-4 col-md-offset-4 text-center">
<br />
#Html.DisplayFor(modelitem => item.NomeGaleria)
<br />
</div>
</div>
<div class="row"><div class="col-md-4 col-md-offset-4 text-center"><div class="nav-informer"></div></div></div>
<div class="row">
<div class="photoset center-block">
#{ var item2 = item.FilePaths;}
#for (var k = 0; k < Enumerable.Count(item2); k++)
{
<br />
<img src="~/images/#Html.DisplayFor(modelItem2 => item2[k].FileName)" style="#(k != 0 ? "display: none" : "" ) " />
<br />
}
</div>
</div>
}
</div>
So I'm trying to use this code
$(this).text(photoset.data('counter') + 1 + " de " + photoset.data('numItems'))
to pass the data to the "nav-informer" div, but it just won't work. Does anyone knows what to do in this case? Sorry if this is a dumb question, I'm very new to jQuery.
UPDATE
Here is the rendered HTML page:
<div class="container">
<div class="row">
<div class="col-md-4 col-md-offset-4 text-center">

<br />

So, since you're new to jQuery, the use of $(this) basically means "the element that I've started the process with" which in your case is .photoset. So $(this) = $('.photoset')
If you want to make that line of text go into your .nav-informer div, you need to change $(this) to $('.nav-informer')
$('.nav-informer').text(photoset.data('counter') + 1 + " de " + photoset.data('numItems'));
UPDATE
So it seems you need to traverse through the hierarchy. Is each 'gallery' a .container? If so, try this:
$(this).closest('.container').find('.nav-informer').text(photoset.data('counter') + 1 + " de " + photoset.data('numItems'));
.closest() traverses up through the hierarchy trying to find the closest parent of the element you start with. (in our case $(this)).
'.find()' does the opposite, it goes down through the hierarchy to find the first instance of the element in question from the point before.
Add them together and what I like to do is .closest() to the parent of the element you're trying to find and .find() the element after that. I feel like doing .parents(), .children() and .siblings() gets messy.
UPDATE 2
Alright, I see now - The way you're exporting each gallery may get a bit dicey eventually, and if possible, I would suggest containing your gallery and informer into the same container, but if you're going to leave it like this, try this:
$(this).closest('.row').prev('.row').find('.nav-informer').text(photoset.data('counter') + 1 + " de " + photoset.data('numItems'));
So, using .parent() will traverse only a single parent, where if you needed to go farther up, you can use .parents() (with an S) or my favorite .closest(). Then, once you reach the level you need to go, you can use .siblings(), or in our case, since your .nav-informer is always in the .row before your .photoset, you need to use .prev(). This will select the div written directly before the div you are currently, at the same level.

I have multiple divs in my HTML with sample class name and I want these divs to behave like a radio button, that is when a div is clicked / selected, I want to achieve following.
1: Change the selected div background color
2: Get values from different elements those are inside the selected div and save the values in variables.
I am able to change the color but I am not able to get the unique values from inside the selected div.
Here is the HTML
<div class="col-lg-4 text-center">
<div class="package">
<input type="hidden" class="packageId" value="5" />
<p class="small">Deep</p>
<h4 class="packageTitle">Deep Cleaning</h4>
<p>All-inclusive cleaning service</p>
<p class="small">Price Per Cleaner</p>
<p class="price packagePrice">41.90 <span class="small">/h</span></p>
</div>
</div>
<div class="col-lg-4 text-center">
<div class="package">
<input type="hidden" class="packageId" value="4" />
<p class="small">Last Minute</p>
<h4 class="packageTitle">Last-Minute Cleaning</h4>
<p>Last minute & after party cleaning</p>
<p class="small">Price Per Cleaner</p>
<p class="price packagePrice">43.90 <span class="small">/h</span></p>
</div>
</div>
<div class="col-lg-4 text-center">
<div class="package">
<input type="hidden" class="packageId" value="3" />
<p class="small">Moving</p>
<h4 class="packageTitle">Move-In-Out Cleaning</h4>
<p>For move-ins, and move-outs</p>
<p class="small">Price Per Cleaner</p>
<p class="price packagePrice">41.90 <span class="small">/h</span></p>
</div>
</div>
And here the the Script
var packageId = "";
var packageTitle = "";
var packagePrice = "";
var packages = document.getElementsByClassName('package');
Array.prototype.forEach.call(packages, function (element) {
element.addEventListener('click', function () {
$('.package').css("background-color", "#FFFFFF");
$(this).css("background-color", "#FCF6CC");
packageId = $('.packageId').attr('value');
packageTitle = $('.packageTitle').text();
packagePrice = $('packagePrice').text();
console.log(packageId);
console.log(packageTitle);
console.log(packagePrice);
});
});
The reason that youre not getiing the unique value is because you are using get element by class ,
ie packagePrice = $('.packagePrice').text();
and there are 3 elements with same class name , to fix this issue
const elem = $(this);
packagePrice = elem.find('.packagePrice').text();
The following code allows me to append new content to the div "users". However, I want to be able remove the appended content if the user clicks button.
The current code removes only the "remove" button when its clicked. However, I need to remove the entire appended code with the class "removeuser", in the beginning of the appended code.
Any help will be appreciated!
<div id="users"></div>
<script>
function adduser() {
count += 1;
$('#users').append('<div id="field'+ count +'" class="removeuser[]"><div
id="left"><div id="fieldname">user #'+ count +' Name:</div><div
id="field"><input id="user_name'+ count +'" name="user_name[]"' + '"

no.onclick = function(){

From what I can tell this is might be the solution you're looking for (note not supported in all browser. See below for transpiled version)...
var count = 0;
adduser();
function adduser() {
$('#users').append(newUser(count))
count++;
}
function deluser(e) {
$(e.target).closest('.user-container').remove();
}
function newUser(count) {
var deleteButton = `
<div>
<a href="javascript: void(0)" onclick="deluser(event); return false;">
<div class="add delete-user" data>
<div style="position:relative;left:-4px;top:1px;">-</div>
</div>
</a>
<br>
</div>
`;
return `
<div class="user-container">
<div id="left">
<div class="fieldname">

<div class="field">
<input id="user_name${count}" name="user_name[]" type="text" /></input>

There area quite a few things wrong with your initial attempt though and I don't mean to be rude, but you should probably do more work learning the basics of HTML, JS and in this case jQuery. Treehouse is where I started out many years ago and think it is a great introduction to web development (Treehouse - front-end web development). That being said here are the most glaring issues...
Unique ids
id attributes must be unique per HTML document. As in, having id="leftleft" and then on another element in same document having id="leftleft" is invalid.
Missing closing bracket of function block }
HTML template strings
Honestly I don't know how you're able to read that HTML template string, but this is one of the issues front-end frameworks like React and Angular are meant to solve. Writing HTML templates like this will definitely introduce bugs and also drive you insane.
Instead or rewriting your whole program in React or Angular I would suggest using Template Literals and either using Webpack + babel to transpile your code to achieve browser support or for now just visit Babel repl and manually drop in your JS (with template literals) then replace with output code.
This is how the code would look after being transpiled through Babel, which would be supported in all browsers..
var count = 0;
adduser();
function adduser() {
$('#users').append(newUser(count));
count++;
}
function deluser(e) {
$(e.target).closest('.user-container').remove();
}
function newUser(count) {
var deleteButton = "\n <div>\n \n <div class=\"add delete-user\" data>\n <div style=\"position:relative;left:-4px;top:1px;\">-</div>\n </div>\n \n <br>\n </div>\n ";
return "\n <div class=\"user-container\">\n <div id=\"left\">\n <div class=\"fieldname\">\n user #".concat(count, " Name:\n </div>\n <div class=\"field\">\n <input id=\"user_name").concat(count, "\" name=\"user_name[]\" type=\"text\" /></input>\n </div>\n <div id=\"clear\"></div>\n </div>\n <div>\n <div class=\"fieldname\">\n user #").concat(count, " Age\n </div>\n <div class=\"field\">\n <input type=\"number\" id=\"user_age").concat(count, "\" name=\"user_age[]\" style=\"width:50px;\" min=\"0\"></input>\n </div>\n <div id=\"clear\"></div><br>\n </div>\n <div>\n \n <div class=\"field\" class=\"add\">\n <div style=\"position:relative;left:-4px;top:1px;\">add another user +</div>\n </div> \n \n <br>\n </div> \n ").concat(count > 0 ? deleteButton : "", "\n <div class=\"clear\">\n </div>\n </div>\n ");
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="users"></div>
use something like this
$( '#users' ).empty();
You need to use following code
var no = $(".deluser"); // add class 'deluser' to each div
no.onclick = function(){
$('#users').empty();
};
I tried to illustrate your approach in another way, I hope it will help you.
var count = 0;
function addUser(i) {
var userBloc = '<li class="list-group-item" id="user'+i+'"> I am the user'+ i +
' <br><button class="btn btn-danger remove" data-count="'+i+'">Remove me</button><hr></li>';
return userBloc;
}
$('#add').click(function(){
$('#blocs').append(addUser(count));
$('#user'+count).fadeIn(activeRemove); //important to active remove event
count++;
});
function activeRemove(){
$.each($('button.remove'), function(i,item){
$(item).click(function(){
$('#user'+$(item).attr('data-count')).remove();
});
});
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="blocs" class="list-group"></div>

"Lightbox" is the common name for what you've described. Since you mentioned a modal bootstrap, something like http://jbutz.github.io/bootstrap-lightbox/ is likely to be aligned with your goals.
simply clone your "field" div, give it id then append to a bootstrap modal body. Or to avoid appending new clone everytime: use .html() instead.
from https://www.w3schools.com/bootstrap/bootstrap_modal.asp with modification, using bootstrap 3.3.7, jquery 3.3.1
<body>
<div class="container">
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<div id='myColumn'>
<img src="https://via.placeholder.com/350x150"/>
<p>Some text in the modal.</p>
</div>
</div>
<script>
$(document).ready(function(){
// var field = $("" + "[data-rubrique-id=" + item.idRub + "]").clone();
var fieldtest= $('#myColumn').clone();
var modal = $("<div id='myModal' class='modal'>\
<div class='modal-dialog'>\
<div class='modal-content'>\
<div id='myBody' class='modal-body'>\

// $('#myBody').html(field);
$('#myBody').html(fieldtest);
});

I know this topic has been asked a lot before but I read a lot of stackoverflow posts and can't figure it out. Either I'm doing a silly mistake or using the code wrong. In any case I'd appreciate other sets of eyes.
My code is actually simple. Elements are being dragged into boxes and I want the user to be able to close the dragged boxes so they can redo the dragging.
<div id="questionContainer">
<div class='row-fluid'>
<div class='span3 box-content'>
<div class="box span12">
<input type="text" placeholder="Column 1" />
</div>
<div class="box span12 groupBoxes">
</div>
</div>
<div class='span3 box-content'>
<div class="box span12">
<input type="text" placeholder="Column 2" />
</div>
<div class="box span12 groupBoxes">
</div>
</div>
<div class='span3 box-content'>
<div class="box span12">
<input type="text" placeholder="Column 3" />
</div>
<div class="box span12 groupBoxes">
</div>
</div>
<div class='span3 box-content'>
<div class="box span12">
<input type="text" placeholder="Column 4" />
</div>
<div class="box span12 groupBoxes">
</div>
</div>
</div>
Then there is the javascript which appends the dragged element. And I have an .on() function there that doesn't work at all.
$( ".groupBoxes" ).droppable({
accept: ".sDrag",
drop: function( event, ui ) {
var studentID = $(ui.draggable).attr('Uid');
var studentName = $(ui.draggable).find(".sName").text();
console.log(studentID + ' ' + studentName);
var dropbox = "<div class='box questionBox' Uid='"+studentID+"' ><div class='box-content box-statistic'><h3 class='title text-error'>"+studentName+"</h3><div class='icon-remove align-right card-remove' style='font-size:12px'></div></div> </div>";
$(this).append(dropbox);
}
});
$("#questionContainer").on('click', '.card-remove', function () {
console.log('hi');
var student = $(this).parent('.questionBox').attr('Uid'); // get user number
var box = $(".studentBox[value='"+student+"']")// find the original object through user
box.removeClass('muted-background').addClass('sDrag');// back in the original object, add class sDrag and remove class muted-background
// remove the object clicked
});
Any ideas about what's going wrong here?
try to define dropbox outside the function
var dropbox;
$( ".groupBoxes" ).droppable({
accept: ".sDrag",
drop: function( event, ui ) {
var studentID = $(ui.draggable).attr('Uid');
var studentName = $(ui.draggable).find(".sName").text();
console.log(studentID + ' ' + studentName);
dropbox = "<div class='box questionBox' Uid='"+studentID+"' ><div class='box-content box-statistic'><h3 class='title text-error'>"+studentName+"</h3><div class='icon-remove align-right card-remove' style='font-size:12px'></div></div> </div>";
$(this).append(dropbox);
}
});
$("#questionContainer").on('click', '.card-remove', function () {
console.log('hi');
var student = $(this).parent('.questionBox').attr('Uid'); // get user number
var box = $(".studentBox[value='"+student+"']")// find the original object through user
box.removeClass('muted-background').addClass('sDrag');// back in the original object, add class sDrag and remove class muted-background
// remove the object clicked
});
Okay, so I am in the process of recreating this feature:
http://www.w3.org/html/logo/#the-technology
I current have it so when you click on a link, it will add a class to the image that relates to that link (href="#one" on the <a> and then id="#one" on the <img>), however it is currently not going through each <a> tag and only one. And also it is not removing the class I requested.
Code follows:
JS
$(document).ready(function() {
var container = '#portfolio #text_container';
var img_container = '#portfolio #image_container';
$(container).children('a').bind('click', function() {
var this_attr = $(this).attr('href');
var this_img = $(img_container).find('img').attr('id');
if(this_attr == this_img) {
//$(img_container).find('img').hasClass('current').removeClass('current');
// ^^^ This line isn't working, any ideas? :/
$(img_container + ' img[id*="' + this_attr + '"]').addClass('current');
}
else {
alert(this_img + ' this img');
alert(this_attr + ' this attr');
}
});
});
And the HTML is as follows
<div id="portfolio">
<div id="image_container">
<img src="http://static.jquery.com/files/rocker/images/logo_jquery_215x53.gif" alt="" class="current" id="#one" />
<img src="http://static.jquery.com/files/rocker/images/btn_downloadLarge.gif" alt="" id="#two" />
</div>
<div id="text_container">
Item 1
Item 2
<p id="#one" class="current">A bunch of text!</p>
<p id="#two">The second bunch of text!</p>
</div>
</div>
Please let me know if you need any more information :)
rcravens fixed this with the following code..
JS
$(document).ready(function() {
$('#text_container a').click(function(evt) {
evt.preventDefault();
$('.current').removeClass('current');
var href = $(this).attr('href');
$("." + href).addClass('current');
});
And the HTML..
<div id="portfolio">
<div id="image_container">
<img src="http://static.jquery.com/files/rocker/images/logo_jquery_215x53.gif" alt="" class="one current" />
<img src="http://static.jquery.com/files/rocker/images/btn_downloadLarge.gif" alt="" class="two" />
</div>
<div id="text_container">
Item 1
Item 2
<p class="one current">A bunch of text!</p>
<p class="two">The second bunch of text!</p>
</div>
</div>
My interpretation of what you are trying to do is here:
http://jsfiddle.net/rcravens/wMhEC/
The code is changed a bit. You shouldn't have multiple elements with the same id.
Bob
The reason this isn't working:
if(this_attr == this_img)
is because this_attr is a URL and this_img is an ID attribute value.
