Delegate/Live Failure. Can't bind events after Prepending an element - javascript

EDIT--- I realized that the problem here was that the click handler that was bound to the element had to be unbound before I could bind another click handler handler.
I want to allow the user to select/unselect items by click on the element in question. The elements start in an "options" box and if clicked, move to a "selected box". If they are then clicked in the selected box, the elements move back to the original options box.
Can't figure out why delegate() and live() are not working here. I assume this has to do with prependTo() or appendTo().
$('#amen_options .options p').click(function(e){
$(this).appendTo('#amen_selected .options');
e.stopPropagation();
e.preventDefault();
});
/*
$("body").delegate('#amen_selected p', 'click', function(e){
#(this).appendTo('#amen_options .options');
e.stopPropagation();
e.preventDefault();
});
*/
$('div#amen_selected div.options p').live('click',function(e){
$(this).appendTo('#amen_options .options');
e.stopPropagation();
e.preventDefault();
});
Here's the markup:
<div>
<div id="amen_options">
<h3>Click to Select</h3>
<div class="options">
<p data-option="">One</p>
<p data-option="">Two</p>
<p data-option="">Etc...</p>
</div>
</div>
<div id="amen_selected">
<h3>Selected</h3>
<div class="options">
</div>
</div>
The first click works (sending p elements from options to selected box). Once in selected, though, no event handlers are binding. The firebug console isn't showing an error. Normally, I'd assume that this is a markup problem, but I've checked it repeatedly.
Thanks!

It looks like delegate() works good.
http://jsfiddle.net/fLXgU/1/
$('body').delegate('#amen_options .options p', 'click', function(e) {
$(this).appendTo('#amen_selected .options');
return false;
});
$('body').delegate('#amen_selected .options p', 'click', function(e) {
$(this).appendTo('#amen_options .options');
return false;
});

getting the value of the button clicked in a group of buttons

html
<div id="group1">
<button>buttonA</button>
<button>buttonB</button>
</div>
javascript
$('#group1').on('click', function(event) {
// get ONLY the value of the button cilcked
});
Is something like this possible without attaching an event to every button in the group?
Add a target selector to the on() and use this or event.currentTarget within the handler function to access the matching element the event occurs on
$('#group1').on('click', 'button', function(event) {
console.log($(this).text())
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="group1">
<button>buttonA</button>
<button>buttonB</button>
</div>

Dynamically create button and then remove that button when clicked in jquery

lHi,
I have some divs in a html doc and when I click the div I am adding a button. eg attached:
HTML:
<div class="week">
<div class="day wk1" id="day1">
<label for="day1">Test</label>
</div>
<div class="day wk1" id="day2">
<label for="day2">Test</label>
</div>
When I add a button by clicking on the div, no problem.
Add Button:
$(".day").click(function (e) {
e.preventDefault();
var check = $("#day7").width() - 2;
var insert = $(this).prop("id");
insert = `#${insert}`;
var par = $('<br class="break"><button class="testing">').html('Shift Manual Insert').width(check).css("background-color", "green");
par.appendTo(insert);
// console.log(insert);
});
When I remove the button by clicking on it it does remove it but simultaneously adds a new button as per the code above and below.
Remove Button:
$(".day").on('click','.testing', function(e){
e.preventDefault();
$(".break").remove;
$(this).remove();
});
I am sure I am doing something silly but for the life of me, I cannot figure it out? Please ignore my incorrect use of id's and classes, this is purely a test to gain experience.
Any help will be most appreciated.
Kind regards
Wayne
The event is getting propagated from the click handler on dom with .testing class to it's parent that is dom with .day class. .day have another click handler which add the element.So after removing the element again $(".day").click(function(e) { is getting fired which is adding back the button element
Replacee.preventDefault(); with e.stopPropagation(); in the click handler of .testing
$(".day").click(function(e) {
console.log('x')
e.preventDefault();
var check = $("#day7").width() - 2;
var insert = $(this).prop("id");
insert = `#${insert}`;
var par = $('<br class="break"><button class="testing">').html('Shift Manual Insert').width(check).css("background-color", "green");
par.appendTo(insert);
// console.log(insert);
});
$(".day").on('click', '.testing', function(e) {
e.stopPropagation();
$(".break").remove;
$(this).remove();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="week">
<div class="day wk1" id="day1">
<label for="day1">Test</label>
</div>
<div class="day wk1" id="day2">
<label for="day2">Test</label>
</div>
Your button is present inside the div. So when you click the button, your div click event is also fired. This is due to event bubbling. Check https://www.w3schools.com/jquery/event_stoppropagation.asp
$(".day").on('click','.testing', function(e){
e.stopPropagation();
e.preventDefault();
$(".break").remove;
$(this).remove();
});

jQuery blur() not listening to $(this)

Followed by the HTML DOM:
<div class="opt">
Options
<div class="panel">
<h3>i am in panel!!</h3>
</div>
</div>
When i click on the .opt it would show the .panel content, but then i need to trigger another event to hide the .panel when clicking outside of the .opt element.
jQuery:
$('.opt').click(function(){
var $this = $(this);
$this.find('.panel').fadeIn();
$this.blur(function(){
$this.find('.panel').fadeOut();
alert('i am from blur');
});
});
Here is a demo JsFiddle
But the blur() method is not executing, what i am doing wrong here technically?
You can try a click event on body instead of blur. Take a look at
https://jsfiddle.net/y0wsfpvb/7/
$('.opt').click(function(){
var $this = $(this);
$this.find('.panel').fadeIn();
});
$('body').click(function (e){
if( $(e.target).closest(".opt").length > 0 == false) {
$('.panel').fadeOut();
alert('fake blur');
}
});
This works if you define de tabindex property for the div...
Try:
HTML
<div class="opt" tabindex="3">
Options
<div class="panel">
<h3>i am in panel!!</h3>
</div>
</div>
JS
$('.opt').click(function(){
$(this).find('.panel').fadeIn();
$(this).blur(function(){
$(this).find('.panel').fadeOut();
alert('i am from blur');
});
});
You could bind the fade out action to the body's on click handler, and then add:
event.stopPropagation();
to your opt class click handler to achieve this.
Here is an example on codepen

Find the id by class in nested div jquery

I have an html like this
<div class='click' id='1'>
one
<div class='click' id='2'>
two
<div class='click' id='3'>
three
<div class='click' id='4'>
four
<div class='click' id='5'>
five
</div>
</div>
</div>
</div>
if i have and click event on class click ,there is any way to return the id of which i click
such as
$('.click').click(function(){
alert('id whitch i click')
});
Becase if i click on three i allway get the id of one and two three.
Sure, just do this:
$('.click').click(function(e){ //e=event
alert($(this).attr("id")); // alert clicked element's id
e.stopPropagation(); // stop event propagation so it doesnt propagate to click 1 and click 2
})
Update: As mentioned by Felix Kling, you can access de DOM directly and use:
alert(this.id);
Demo: http://jsfiddle.net/tzJUN/ using this.id http://jsfiddle.net/c65x9/
If you keen : jQuery attr vs prop?
Stop propogation will stop the click event the event from bubbling up the DOM tree, preventing any parent handlers from being notified of the event.
API:
.stoppropagation - http://api.jquery.com/event.stoppropagation/
Code
$(document).ready(function () {
$('.click').click(function (event) {
event.stopPropagation();
alert($(this).prop("id")); //<< --- or this.id
});
});
$('.click').click(function(e){
$(this).attr("id");
alert($(this).attr("id"));//here you can see your clicked id
})
Yes. its simple
$(document).ready(function(){
$('.click').click(function(){
var ID=$(this).attr('id');
alert(ID);
//This ID varible will return ID of the Div Clicked
});
});

How to execCommand from li?

I'm losing focus on contentEditable when my menu li option is clicked so when I try to execCommand the selection no longer exists and does not affect the selection. How can I solve this without adding an input?
Updated:
** jsFiddle **
HTML
<div contenteditable=true>
paragraph1<br/>
paragraph2<br/>
paragraph3
</div>
<div contenteditable=true>
paragraph4<br/>
paragraph5<br/>
paragraph6
</div>
<input type=button id=show value=ToggleMenu>
<ul id=submenu>
<li>p</li>
<li>h1</li>
<li>h2</li>
</ul>
Javascript
$("#show").on("click",function(){
$("#submenu").toggle();
});
$("#submenu").on("click","li",function(){ //when this is clicked, editable div loses focus.
document.execCommand("formatBlock", false, $(this).text());
console.log($(this).text(), "was clicked");
});
You could do something like the following:
use mousedown instead of click
prevent the default event behaviour
get the relevant <li>'s content
call document.execCommand()
Demo: http://jsfiddle.net/timdown/SNTyY/13/
Code:
var $submenu = $("#submenu");
$("#show").on("click",function(){
$submenu.toggle();
});
$submenu.mousedown("li",function(e){
var li = e.target;
e.preventDefault();
document.execCommand("formatBlock", false, $(li).text());
});
$submenu.click(function(e) {
e.preventDefault();
});
One issue with your code is that it is not HTML compliant. For example, the sub menu should be
<ul id = 'submenu'>
<li>p</li>
<li>h1</li>
<li>h2</li>
</ul>
Instead of using li as a selector for your click event, try
$("#submenu").on("click", "li", function(){
document.execCommand("formatBlock", false, $(this).text());
alert($(this).text());
});
This throws an alert box on a click event, so you know the click is registering.
