Jquery not detect click after append of element - javascript

i've made a sortable list with html5sortable library, where user have a category, where can add products inside, and can add other categories where to add products too.
The first one category is already displayed, and work fine when adding products, but if I add another category I can't add product on this category.
I've tried with "on" method instead of "click", as it should work on element created dinamically, but I think I'm using it in the wrong way.
Here is the HTML
<div class="container-categorie">
//THIS IS A CATEGORY ITEM, WITH ADD PRODUCT BUTTON INSIDE
<div class="category" id="categoria-1">
<input type="text" class="input-categoria" placeholder="NAME CATEGORY" autofocus="autofocus">
<div class="list" id="list-1">
//products will be added here
</div>
<div class="item-products add-product-container">
<div align="center" class="add-product-btn" id="addproduct-1">
+ add product
</div>
</div>
</div>
//END OF CATEGORY ITEM
<div class="add-categoria-container">
Nuova categoria
</div>
</div>
And here is the js code:
var i = 2;
$(".categoria").on('click', function() {
//to delegate the click I applied this event to "add product" button's container
});
//This add a product inside category div
$(".add-product-btn").click(function() {
var id_btn = $(this).attr("id");
var single_id = id_btn.substring(id_btn.indexOf("-") + 1);
$("#list-"+single_id).append('<div class="item-products">prova</div>');
sortable('.list');
});
//This should add a new category inside "container-categorie", with an "add product"
//button inside, to add products inside this new category
$(".add-categoria-container").click(function() {
$(".sortable-categorie").append('<div class="categoria"><input type="text" class="input-categoria" placeholder="NOME CATEGORIA PRODOTTI" autofocus="autofocus"><div class="list" id="list-'+i+'"></div><div class="item-products add-product-container"><div align="center" class="add-product-btn" id="addproduct-'+i+'">+ Aggiungi prodotto</div></div></div>');
sortable('.sortable-categorie');
});

Jquery can't listen to dynamically generated Elements directly, what you can do is you can provide parent element which is already there in DOM listen to them.
$("element which is already in DOM").on('click',"element to listen to", function() {
//Code here
});
$(".container-categorie").on('click',".categoria", function() {
//Code here
});
or you can directly listen to the body instead, but it is not preferable.
For Ref : https://api.jquery.com/on/#on-events-selector-data-handler

Try this
$(document).on('click',".your_class_name", function() {
//to delegate the click I applied this event to "add product" button's container
});

JQuery has no virtual DOM like Angular or React. That means JQ can't "see" the dynamically generated element. What you can do is using a onclick="functionYouWantToTrigger(someParameters)" directly in the HTML tag.

When click on button, show divs with checked checkbox using JQuery

I want to use JQuery on my Coldfusion application for showing/hiding div elements with checkbox checked/unchecked within the div.
Basically, in a view I show multiple divs elements, every div have also more divs inside, one of these internal divs contains an input type checkbox that could come checked or unchecked.
I also have three buttons in that view 'Active, Inactive, All'. When clicking on Active I want to show all div elements with checkbox checked, not showing the unchecked, and the other way around when clicking on Inactive.
<div class="btn-group ">
<button id="actives" type="button">Actives</button>
<button id="inactives" type="button">Inactives</button>
<button id="all" type="button">All</button>
</div>
<div id="apiDiv">
<cfloop array="#apis#" index="api">
<div class="card card-found">
<div class="card-header">
<cfif Len(api.iconClass)>
<i class="fa fa-fw #api.iconClass#"></i>
</cfif>
#structKeyExists( api, "name" ) ? api.name : api.id#
</div>
<div class="card-body">
<p>#api.description#</p>
</div>
<div class="card-button">
<input class="#inputClass# ace ace-switch ace-switch-3" name="#inputName#" id="#inputId#-#api.id#" type="checkbox" value="#HtmlEditFormat( api.id )#"<cfif ListFindNoCase( value, api.id )> checked="checked"</cfif> tabindex="#getNextTabIndex()#">
<span class="lbl"></span>
</div>
</div>
</cfloop>
</div>
I´m not an expert at all with JQuery. The only thing I have done is what follows and I do not know whether if is a good beggining or not:
$("#actives").click(function (e) {
$("#apiDiv .card").filter(function() {
<!--- code here --->
});
});
Someone please that can help me with it? Thanks a lot in advance!
After your CF code executes, it will generate a .card for each loop iteration of your apis array. So you jQuery code will need a click handler for the #actives button and that will loop through each() iteration of the checkboxes to determine the checked/unchecked state. At that point find the closest() ancestor .card and show()/hide() the .card depending upon the checkbox state.
$("#actives").click(function (e) {
$('input[type=checkbox]').each(function() {
if (this.checked) {
$(this).closest(".card").show();
} else {
$(this).closest(".card").hide();
}
});
});
If you want to do it with jQuery code:
$('#actives').click(function(){
$('#apiDiv').show();
});
Working Fiddle
The code you are probably looking for is in these event handlers for your buttons:
function activesHandler() {
jQuery(".card-button > input:checked").parents(".card.card-found").show();
jQuery(".card-button > input:not(:checked)").parents(".card.card-found").hide();
}
function inactivesHandler() {
jQuery(".card-button > input:checked").parents(".card.card-found").hide();
jQuery(".card-button > input:not(:checked)").parents(".card.card-found").show();
}
function allHandler() {
jQuery(".card.card-found").show();
}
jQuery("#actives").click(activesHandler);
jQuery("#inactives").click(inactivesHandler);
jQuery("#all").click(allHandler);
I reproduced some of your ColdFusion by replacing it with JavaScript and provided a demonstration of the above event handlers in this JSFiddle.
Call the checkbox by its id and when it's checked, write a function to display the divs you want to display:
<input type="checkbox" id="check">
$document.getElementById("check").onclick = function(){
$document.getElementById("div_name").style.display="block"; // block displays the div.
}

Why isn't jQuery append method working when passing parent class to add a child input?

I want to append a duplicate of an input box in a parent box. Here is my HTML structure:
<div class="reading-group input-group">
<input type="text" placeholder="Enter Reading link" id="link">
</div>
+ Add another link
And here is my jQuery code:
function addPlaceholder(parentClass){
var placeHolder = $(parentClass).children().eq(0);
$(parentClass).append(placeHolder);
console.log(placeHolder);
}
$('.add-reading-btn').click(function(){
addPlaceholder('.reading-group');
});
Here is the jsfiddle link: https://jsfiddle.net/abhishekraj007/kexe6gxn/
What am I doing wrong?
Your code is taking the existing <input> element and moving it from the <div> and back into the <div>, so it looks like nothing is happening. If you .clone() the element and then .append() it, a new element will be added.
Here is a working example:
function addPlaceholder(parentClass) {
var placeHolder = $(parentClass).children().eq(0).clone();
$(parentClass).append(placeHolder);
console.log(placeHolder);
}
$('.add-reading-btn').click(function() {
addPlaceholder('.reading-group');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="reading-group input-group">
<input type="text" placeholder="Enter Reading link" id="link">
</div>
+ Add another link
If you want to add focus to your <input> element on load, you can do so by adding this line to the bottom of your code:
$('#link').focus();
If you want to add focus to the new element on creation, as well as give it an empty value rather than copying the prior element's value, add this line to the end of your addPlaceholder() function:
$(placeHolder).val("").focus();
you can just add the .clone() method of jquery to create a clone of the textbox like below . You were only referring to the same element not the cloned html before.
$(document).ready(function(){
function addPlaceholder(parentClass){
var placeHolder = $(parentClass).children().eq(0).clone();
$(parentClass).append(placeHolder);
//console.log(placeHolder);
}
$('.add-reading-btn').click(function(){
addPlaceholder('.reading-group');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="reading-group input-group">
<input type="text" placeholder="Enter Reading link" id="link">
</div>
+ Add another link

Getting div containers to display hidden and then show with a button

I am creating an admin panel and I have a panel on the left side of my page that I want to bring up different data.
I created a JSFiddle to show what I am doing.
The issue I am having is I want the dashboard home message...
<div id="dashboard_home">Welcome to the Admin Dashboard</div>
To be the only div that shows up on page load. Then when a panel seletion is clicked on, for the dashboard home message to go away and then only that new panel selection's div to show up.
Then once another panel selection is clicked on, I want the previous selection to hide and the new one to display and so fourth for all of the selections.
What do I need to do?
HTML
<div class="panel_out">
<div class="panel">
<input type='button' class="panel_buttons" id='user_request_button' value='User Requests'>
<input type='button' class="panel_buttons" id='message_button' value='Message Center'>
<input type='button' class="panel_buttons" id='draft_order_button' value='Draft Order'>
<input type='button' class="panel_buttons" id='draft_input_button' value='Draft Input'>
<input type='button' class="panel_buttons" id='announcements_button' value='Announcements'>
<input type='button' class="panel_buttons" id='dues_button' value='League Dues'>
</div>
</div>
<div class="dashboard_selection">
<div id='user_requests'>User Requests</div>
<div id='message_center'>Message Center</div>
<div id='draft_order'>Draft Order</div>
<div id='draft_input'>Draft Input</div>
<div id='announcements'>Announcements</div>
<div id='dues'>Leauge Dues</div>
</div>
JS
jQuery(document).ready(function () {
jQuery('#user_request_button').on('click', function (event) {
jQuery('#user_requests').toggle('hide');
});
jQuery('#message_button').on('click', function (event) {
jQuery('#message_center').toggle('hide');
});
jQuery('#draft_order_button').on('click', function (event) {
jQuery('#draft_order').toggle('hide');
});
jQuery('#draft_input_button').on('click', function (event) {
jQuery('#draft_input').toggle('show');
});
jQuery('#announcements_button').on('click', function (event) {
jQuery('#announcements').toggle('show');
});
jQuery('#dues_button').on('click', function (event) {
jQuery('#dues').toggle('show');
});
});
Demo
You're adding far too many bespoke events when you don't need to. Normalise your IDs to match the button IDs and derive one from the other,
e.g. <input id='user_requests_button' /> finds <div id="user_requests">
Show the div you want, then use siblings() to get the elements that you want hidden, and hide them.
Trigger the click event on the first button on load to show the first one only when the page loads (if you don't do this with CSS).
jQuery(document).ready(function () {
$('.panel_out input').on('click', function(){
// derive the ID
var id_to_show = '#' + this.id.replace('_button', '');
// show one and hide the others
$(id_to_show).show().siblings().hide();
}).first().trigger('click'); // trigger the first on page load
});
Trigger the click event on the first button on load to show the first one only when the page loads (if you don't do this with CSS).
On a click hide all panels first. And then open the desired one with .show()
So i would do it this way:
$('.panel').click(function(e){
$('.panel').hide();
$(e.currentTarget).closest('panel').show();
});

Hide existing <div> and show previous <div> in multi-branch form

I will start by telling you that this is my very first Javascript program from scratch. I am trying to make a back button that will go to the previously chosen div in a form (hide the current div and show the previous one the user chose).
The form has multiple paths to follow, paths within paths and not all selectors are buttons. There might be an onchange event or a radio button or even text input (text inputs have a next button to click).
I have had it working where it will hide the current div but show all previous chosen divs. It's now working where it hides the current div but shows nothing.
I have read a bunch of postings here and in other forums but have not found what I need yet. Any help would be greatly appreciated.
You can see the actual site here and I have put up a JSfiddle but for some reason I can't get it working there.
Here is the code from the fiddle:
<div>
<form>
<div id="uno" class="showFirst">
<button onclick="hideUno()">First Button</button>
</div>
<div id="dos" class="hideFirst">
<button onclick="hideDos()">Second Button</button>
</div>
<div id="tres" class="hideFirst">
<button onclick="hidetres()">Third Button</button>
</div>
<div id="quattro" class="hideFirst">
<button onclick="hideQuattroUno()">Fourth Button</button>
<button onclick="hideQuattroDos()">Fifth Button</button>
</div>
<div id="branchUno" class="hideFirst">
<p>First Branch</p>
</div>
<div id="branchDos" class="hideFirst">
<p>Second Branch</p>
</div>
</form>
<button id="backButton" onclick="goToPrevious" class="hideFirst">Back</button>
</div>
.hideFirst {
display: none;
}
function goToPrevious() {
var current = $(".chosen").find(":visible");
$(current).hide();
$(current).prev(".chosen").show();
}
function hideUno() {
$("#backButton").toggle();
$("#uno").toggle();
$("#uno").addClass("chosen");
$("#dos").toggle();
}
function hideDos() {
$("#dos").toggle();
$("#dos").addClass("chosen");
$("#tres").toggle();
}
function hideTres() {
$("#tres").toggle();
$("#tres").addClass("chosen");
$("#quattro").toggle();
}
function hideQuattroUno() {
$("#quattro").toggle();
$("#quattro").addClass("chosen");
$("#branchUno").toggle();
}
function hideQuattroDos() {
$("#quattro").toggle();
$("#quattro").addClass("chosen");
$("#branchDos").toggle();
}
Here are a few of the questions I've reviewed here:
retain show / hide div on multistep form
Hide and Show div in same level
how to show previous div of clicked div in angular.js
show div and hide existing div if open with jQuery?
Show one div and hide the previous showing div
I realize it's not the cleanest code, but as I said this is my first and I am trying to cleanup as I go along and learn new things.
You could make a bit of automatization instead of creating onclick events for each button/select separately.
For "Back" functionality, I'd use an array to store elements "on the fly" at each step, instead of checking visibility later on.
I'll make it this way:
Remove CSS rule display:none for hideFirst class (elements will be hidden using jQuery).
Add an class to the buttons/selects/check-boxes/etc... as event inndicator.
Add data-next attribute (to store id of the element which should be shown on click/change)
HTML:
<div id="firstDiv" class="hideFirst">
<button class="my-btn" data-next="#secondDiv" type="button">Show next<button>
</div>
<div id="secondDiv" class="hideFirst">
<select class="my-select" data-next="#thirdDiv">
<option>Helo World</option>
...
</select>
</div>
...
Script:
$(document).ready(function(){
// hide all 'hideFirst' elements, except the first one:
$('.hideFirst:not(:first)').hide();
// declare 'history' variable as an empty array (it will be used to store 'hideFirst' elements for 'Back' functionality):
var history = [];
// click event for the buttons :
$('.my-btn').click(function(e){
// as the button will submit the form if you're not using type="button" attribute, use this:
e.preventDefault();
showNext($(this));
});
// change event for selects :
$('.my-select').change(function(){
showNext($(this));
});
// Method used to show/hide elements :
function showNext(el){
// check if element has a 'data-next' attribute:
if(el.data('next')){
// hide all elements with 'hideFirst' class:
$('.hideFirst').hide();
// show 'Back' button:
$('#backButton').show();
// show the element which id has been stored in 'data-next' attribute:
$(el.data('next')).show();
// Push the parent element ('.hideFirst') into history array:
history.push(el.closest('.hideFirst'));
}
}
// click event for 'back' button:
$('#backButton').click(function(){
// hide all elements with 'hideFirst' class:
$('.hideFirst').hide();
// remove the last '.hideFirst' element from 'history' array and show() it:
history.pop().show();
// hide 'back' button if history array is empty:
history.length || $(this).hide();
}).hide(); // hide 'back' button on init
});

jQuery cannot recognize appended cloned elements using jQuery.appendTo()

I want to make a list of group inputs allow user to dynamically let user add/remove group row:
<div id="div-form-denominations" class="form-denominations">
<div id="row-0" class="form-denomination">
<div class="form-field">
<div class="form-field">
<div class="form-field">
<input id="_denominations[0].id.reference" class="removableHiddenOrder" type="hidden" name="denominations[0].id.reference" value="87-070329-034COP-4444">
<input id="_denominations[0].denomination" class="removableHiddenDenom" type="hidden" name="denominations[0].denomination" value="10000">
<a id="deleteBtn-[0]" class="action-link delete-denomination" href="#">
<div class="spacer"></div>
</div>
<div id="row-1" class="form-denomination">
<div class="form-field">
<div class="form-field">
<div class="form-field">
<input id="_denominations[1].id.reference" class="removableHiddenOrder" type="hidden" name="denominations[1].id.reference" value="87-070329-034COP-4444">
<input id="_denominations[1].denomination" class="removableHiddenDenom" type="hidden" name="denominations[1].denomination" value="">
<a id="deleteBtn-[1]" class="action-link delete-denomination" href="#">
<div class="spacer"></div>
</div>
<div id="row-2" class="form-denomination">
<div class="form-field">
<div class="form-field">
<div class="form-field">
<input id="_denominations[2].id.reference" class="removableHiddenOrder" type="hidden" name="denominations[2].id.reference" value="">
<input id="_denominations[2].denomination" class="removableHiddenDenom" type="hidden" name="denominations[2].denomination" value="">
<a id="deleteBtn-[2]" class="action-link delete-denomination" href="#">
<div class="spacer"></div>
</div>
<div id="row-3" class="form-denomination">
.......
</div>
So each row include a group of form-field which include an input or select component(not show in above code) and some hidden fields and a delete link to remove current row from view.
Also I create a link to dynamic add a new row into the section
var rowTemplate = null;
j(document).ready(function() {
// Save the row template
rowTemplate = j('.form-denomination:first-child').clone();
j("#add_link").click(function() {
add_denomination();
});
});
and here is the content of add_denomination function that clone the first row and replace any cloned id with new index, and append the cloned row after last row of the list.
function add_denomination() {
var index = j('.form-denomination').length;
// set the new row id
var newRowId = 'row-' + index;
var newRow = rowTemplate.clone().attr('id', newRowId);
// Replace the id/name attribute of each input control
newRow.find('div, input, select, a').each(function() {
replaceAttribute(j(this), 'id', index);
replaceAttribute(j(this), 'name', index);
j(this).val('');
});
// add new element to the DOM
newRow.appendTo('.form-denominations');
alert("new list size = " + j(".delete-denomination").length);
console.log("DONE!");
}
each time click on the add-link the pop up alert show the new list size (j(".delete-denomination").length increment by 1), which in my understanding, new row appended successfully.
The problem is the following method
// delete denomination row
j('.delete-denomination').click(function () {
j(this).parent().remove();
}
ONLY WORKS FOR THE NON-CLONED ROW !!! Using firebug I can clearly see the appended row is successfully appended with same structure and same element as original rows but only difference is the id.
However, each time when I click on deleteBtn-[i], in which i is the cloned/appended row's index, the code even not going into the j('.delete-denomination').click() function, which in my understanding, Dom or jquery didn't recognize the new rows hence the failure of identifying the link by jQuery. It's kind of contradictory to the previous alert message that telling the size of list has grown.
But when I click on deleteBtn-[i] where i is the non-cloned row, everything works fine...
So the question is: how to append/add new doms and make them identified by jQuery or Dom? What is wrong in above processing? Is there any way to refresh the list so that Dom/jQuery understand the appended rows from all perspective?
jQuery 1.7+
j(".form-denomination").on("click", ".delete-denomination", function(){
j(this).parent().remove();
});
jQuery 1.3+
j(".delete-denomination").live("click", function(){
j(this).parent().remove();
});
jQuery 1.4.3+
j(".form-denomination").delegate(".delete-denomination", "click", function(){
j(this).parent().remove();
});
The problem is a matter of order and when expressions are evaluated. When you call jQuery with a selector, the selector is evaluated at that time to select the matching elements which exist at that time. The click handler is then registered to only those elements. Elements which are created later are, naturally, not affected.
One solution, demonstrated in another example, uses jQuery's "live events" to apply the selector at the time each event is fired to determine what elements, if any, it would match. There is a performance implication to this approach.
Another solution is to register the desired event handler on the newly created elements when you create them.
Add 'true' to the clone method in order to copy the data as well as the events attached to the original element.
rowTemplate = j('.form-denomination:first-child').clone(true);
This is disabled by default. Here is the clone documentation:
https://api.jquery.com/clone/
P.s. You don't need the click function within the document.ready and it won't bind until after the click.
