Jquery onclick function called two time on dynamically added button element

I have created a code on my HTML page that their multiple checkboxes and created one button dynamically in js snippet for performing some event, but when I clicked on the button to perform that even that, then it's making calls to that event snippet two times. I wanted to know how to add the event to that button.
Here is the js code:-
$(".panel-body").on("click", '#select_none', function(event) {
$("input[name='nodelevel']:checkbox").each(function() {
this.checked = false;
});
});

Make sure there is only one parent with .panel-body class name. maybe there is two of .panel-body and it makes this happen. like this:
<div class="panel-body">
...
<div class="panel-body">
...
<!-- your selectors -->
</div>
</div>
try stoppropagation to avoid second parent event listener call:
$(".panel-body").on("click", '#select_none', function(event) {
event.stopPropagation();
$("input[name='nodelevel']:checkbox").each(function() {
this.checked = false;
});
});
EDIT : and of course you can add listener to document instead of .panel-body :)

Example:
<input class="itemClass" type="checkbox" name="Items" value="Bike"> I have a bike<br>
<input class="itemClass" type="checkbox" name="Items" value="Car" checked> I have a car<br>
<button name="submit" onclick="getValue()" value="Submit">
Then:
function getValue() {
var id;
var name;
var temp = [];
$('.itemClass').each(function () {
var sThisVal = (this.checked ? $(this).val() : "");
console.log(sThisVal);
if (this.checked) {
// $("input[name=Items]:checked").map(function () {
temp.push(sThisVal);
}
});
console.log(temp);
$('.itemCheckboxClass').prop('checked', false);
}

Jquery method to capture checkbox click inside nested div

<div class="panel-body" id="sell_in">
#foreach (var state in Model.States)
{
<div class="checkbox">
<label>
<input type="checkbox" name="SelectedStates" id="buy_#state.Value" value="#state.Value" /> #state.Text
</label>
</div>
}
</div>
I need to capture when any of the 50 checkboxes are checked. This isn't doing it, and I expect it's because the checkboxes are nested in another <div> under sell_in.
$(document).on("click", "div.sell_in", function (event) {
alert("hello");
});
(I got this solution from here: checkbox inside div. On click checked or unchecked using jquery 1.9.1)

Try to select checkbox's using input:checkbox :
$(document).on("click", "input:checkbox", function (event) {
alert("hello");
});
Or specify the ones inside div using :
$(document).on("click", "div#div_id_here input:checkbox", function (event) {
alert("hello");
});
Hoep this helps.

JQuery loop through multiple input checkboxes

I am tasked with having one checkbox within multiple divs. When the checkbox is checked, I want to hide the div. I want to use Jquery to implement this functionality. I feel I am close, but missing something essential.
Here is my code and any help would be greatly appreciated.
Thanks,
Roka
<div id='legGroup1' class="elementGroup">
<input type="checkbox" class="delCheck" id="1" />Delete</label>
</div>
<div id='legGroup2' class="elementGroup">
<input type="checkbox" class="delCheck" id="2" />Delete</label>
</div>
<button type='button' id='removeLeg'></button>
$("#removeLeg").click(function (e) {
$('.delCheck').each(function () {
if (this.id.prop('checked')) {
$("#legGroup" + this.id).hide();
}
});
});

You can simply find the parent element:
$("#removeLeg").click(function() {
$('.delCheck:checked').each(function() {
// ^^^^^^^^ -> look it filters only checked elements
$(this).parent().hide();
});
});
Or, more accurate, using closest method:
$(this).closest('.elementGroup').hide();

Since your using an each function, base it off the value of the items in the array the function returns.
$("#removeLeg").click(function (e) {
$('.delCheck').each(function (key, value) {
if ($(value).is(':checked')) {
$(value).parent().hide();
}
});
});

First of all, you're missing an open label tag in your HTML.
<label><input type="checkbox" class="delCheck" id="1" />Delete</label>
As for the click event, you can try this, to loop through each checked checkbox and hide their closest div parent.
$(document).ready(function(){
$('#removeLeg').on('click', function(){
$('.delCheck:checked').each(function(){
$(this).parents('div').hide();
});
});
});

JQuery .prop function not working to uncheck box

I tried many of the ideas I found here to uncheck a checkbox when a different checkbox is checked, but none are working ...
Right I now I have :
$("#chkBox1").click(function () {
if ($(this).is(":checked")) {
$('#chkBox2').prop('checked', false); }
});
..but no results, chkBox2 remains checked
here is a checkbox in HTML:
<input type="checkbox" name="art" id="chkBox1" data-mini="true" data-theme="c" />
one possible difference in my code is that the checkboxes are only added to the page when a button is clicked, using href...the checkboxes are in the HTML (not created in Javascript)..but are not visible until a button is clicked..may this be part of the problem? Or am I missing something else? Also, I am using JQuery Mobile.

You need to refresh it after changing its' .prop, using .checkboxradio('refresh').
Demo
// Check #chkBox2 by default
$('#chkBox2').prop('checked', true).checkboxradio('refresh')
// Uncheck #chkBox2 when #chkBox1 is checked
$('#chkBox1').on('click', function () {
if ($(this).is(':checked')) {
$('#chkBox2').prop('checked', false).checkboxradio('refresh');
}
});
jQuery Mobile API reference

sorry, I should have kept reading!
this seems to do the trick:
$('#chkBox1').checkboxradio('refresh');
..but I am not exactly sure why, is this something unique to JQuery Mobile?

Html
<input type="checkbox" name="art" id="chkBox1" data-mini="true" data-theme="c" />
<input type="checkbox" name="art2" id="chkBox2" data-mini="true" data-theme="c" checked="checked" />
jQuery:
(function ($) {
$(document).ready(function () {
$("#chkBox1").click(function () {
if ($(this).is(":checked")) {
$('#chkBox2').prop('checked', false);
}
});
});
})(jQuery);
Working example here http://jsfiddle.net/SwmN6/75/

You are checking this, and changing chkBox2:
if ($(this).is(":checked")) {
$('#chkBox2').prop('checked', false); }
Try this instead:
if ($('#chkBox2').is(":checked")) {
$('#chkBox2').prop('checked', false); }
Or simply:
$('#chkBox2').prop('checked', false);

trouble with jquery and traversing the DOM to select the appropriate elements

Hello guys i have the below html for a number of products on my website,
it displays a line with product title, price, qty wanted and a checkbox called buy.
qty input is disabled at the moment.
So what i want to do is,
if the checkbox is clicked i want the input qty to set to 1 and i want it to become enabled.
I seem to be having some trouble doing this. Could any one help
Now i can have multiple product i.e there will be multiple table-products divs within my html page.
i have tried using jQuery to change the details but i dont seem to be able to get access to certain elements.
so basically for each table-product i would like to put a click listener on the check box that will set the value of the input-text i.e qty text field.
so of the below there could be 20 on a page.
<div class="table-products">
<div class="table-top-title">
My Spelling Workbook F
</div>
<div class="table-top-price">
<div class="price-box">
<span class="regular-price" id="product-price-1"><span class="price">€6.95</span></span>
</div>
</div>
<div class="table-top-qty">
<fieldset class="add-to-cart-box">
<input type="hidden" name="products[]" value="1"> <legend>Add Items to Cart</legend> <span class="qty-box"><label for="qty1">Qty:</label> <input name="qty1" disabled="disabled" value="0" type="text" class="input-text qty" id="qty1" maxlength="12"></span>
</fieldset>
</div>
<div class="table-top-details">
<input type="checkbox" name="buyMe" value="buy" class="add-checkbox">
</div>
<div style="clear:both;"></div>
</div>
here is the javascript i have tried
jQuery(document).ready(function() {
console.log('hello');
var thischeck;
jQuery(".table-products").ready(function(e) {
//var catTable = jQuery(this);
var qtyInput = jQuery(this).children('.input-text');
jQuery('.add-checkbox').click(function() {
console.log(jQuery(this).html());
thischeck = jQuery(this);
if (thischeck.is(':checked'))
{
jQuery(qtyInput).first().val('1');
jQuery(qtyInput).first().prop('disabled', false);
} else {
}
});
});
// Handler for .ready() called.
});

Not the most direct method, but this should work.
jQuery(document).ready(function() {
jQuery('.add-checkbox').on('click', function() {
jQuery(this)
.parents('.table-products')
.find('input.input-text')
.val('1')
.removeAttr('disabled');
});
});

use
jQuery('.add-checkbox').change(function() {
the problem is one the one hand that you observe click and not change, so use change rather as it really triggers after the state change
var qtyInput = jQuery(this).children('.input-text');
another thing is that the input is no direct child of .table-products
see this fiddle

jQuery('input:checkbox.add-checkbox').on('change', function() {
jQuery(this)
.parent()
.prev('div.table-top-qty')
.find('fieldset input:disabled.qty')
.val(this.checked | 0)
.attr('disabled', !this.checked);
});

This should get you started in the right direction. Based on jQuery 1.7.2 (I saw your prop call and am guessing that's what you're using).
$(document).ready(function() {
var thischeck;
$('.table-products').on('click', '.add-checkbox', function() {
var qtyInput = $(this).parents('.table-products').find('.input-text');
thischeck = $(this);
if (thischeck.prop('checked')) {
$(qtyInput).val('1').prop('disabled', false);
} else {
$(qtyInput).val('0').prop('disabled', true);
}
});
});
Removing the property for some reason tends to prevent it from being re-added. This works with multiple tables. For your conflict, just replace the $'s with jQuery.
