css toggle switch status - javascript

So here is what I have for a toggle switch I'm using off of https://metroui.org.ua/inputs.html
What Im trying to do is change the label thats before the switch/checkbox to say checked or not checked. If I click on the label it changes the switch but the text does not change.
JavaScript:
$(document).ready(function() {
$('#front_set').click(function() {
if ($(this).is(':checked')) {
$(this).siblings('label').html('checked');
} else {
$(this).siblings('label').html(' not checked');
}
});
});
<label for="front_set">checked</label>
<label class="switch-original right">
<input type="checkbox" id="front_set">
<span class="check"></span>
</label>

The issue: The label is not a sibling of the clicked checkbox, so you won't find it using siblings. The label is actually a sibling of the label that is the parent of the checkbox.
The solution: Use a different selector to find the label, so their relative positions don't matter much anymore. Using label[for="xyz"] you can find exactly that label that is bound to checkbox xyz, regardless of its position in the document. This makes your code more flexible too, because it won't break immediately if you reorganize your DOM.
var $myLabel = $('label[for="' + this.id + '"]');
$myLabel.html( $(this).is(':checked') ? 'checked' : ' not checked');
$(document).ready(function() {
$('#front_set').click(function() {
var $myLabel = $('label[for="' + this.id + '"]');
$myLabel.html( $(this).is(':checked') ? 'checked' : ' not checked');
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="front_set">checked</label>
<label class="switch-original right">
<input type="checkbox" id="front_set">
<span class="check"></span>
</label>

You need to change the parent().siblings('label'), not .siblings('label') because $(this) is the element you bind the click event to, which is $('#front_set') ( = your input) and that's a child of <label>, not a sibling of it. So you need to go up a level, using .parent():
$(document).ready(function() {
$('#front_set').click(function() {
if ($(this).is(':checked')) {
$(this).parent().siblings('label').html('checked');
} else {
$(this).parent().siblings('label').html(' not checked');
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="front_set">checked</label>
<label class="switch-original right">
<input type="checkbox" id="front_set">
<span class="check"></span>
</label>
What I don't understand is what is that <span class="check"></span> doing in your code? It does nothing and your code would do well without it.
Improved version:
You shouldn't bind events on click to checkboxes, but on change, as checkboxes can change their value without being clicked. So here is a better version of it, most likely to work on any device, in any browser:
$(document).on('ready', function() {
$.fn.extend({
setLabel: function() {
var label = $('[for="'+$(this).attr('id')+'"]').eq(0);
$(label).text(($(this).is(':checked') ? '' : 'not ') + 'checked');
}
});
$('#front_set').on('change', function(){
$(this).setLabel();
})
$('#front_set').setLabel();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<label for="front_set">checked</label>
<label class="switch-original right">
<input type="checkbox" id="front_set">
</label>
This also registers the checking of the label as a jQuery function, enabling you to call it on any element using .setLabel(). In this version I used GolezTrol's solution for selecting the label, since it adds flexibility (the parent/child relation between input and label is no longer relevant).

How can I check with JQuery if a checkbox is checked and if so add a class to the parent label?

I would like, on load of the page, to check if a checkbox is :checked Then if it is, add a class to the label. I currently have the following script but it doesn't work.
$(document).ready(function() {
$('input').is(':checked') {
$(this).parent('label').toggleClass('label--active');
});
});
My HTML is:
<label class="container-checkbox" for="checkOne">
<span class="checkbox-label">Option one</span>
<input type="checkbox" id="checkOne">
<span class="checkmark"></span>
</label>
I can not change the DOM order as these are custom checkboxes.
I guess you can use this:
$(document).ready(function() {
let checkboxone = document.getElementById('checkOne');
checkboxone.addEventListener('change',function() {
checkboxone.parentNode.classList.toggle('label--active');
});
});
How does is work?
Everytime when the checkbox is clicked, the class 'label--active' will be added / removed.

jQuery On click wont fire

I have a textbox, a checkbox and a span tag. When I click on the checkbox, it should show its state in the span tag. When textbox is updated, it reinserts the checkbox block. When you click on the checkbox now, it fails to update the state.
I am using the on event handler for checkbox click event, so I expect it to work.
Any idea why this is not working as expected?
$('div[role] input[type=checkbox]').on('click', chg);
$('div[role] input[type=text]').on('input', sourceChanged);
function chg() {
var istiki = $(this).is(":checked");
$('#upd').html(istiki);
}
function sourceChanged() {
$('span', $(this).closest('.input-group')).html('<input type="checkbox">');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div role="Tiki" class="input-group">
<input type="text" class="form-control" />
<span class="input-group-addon"><input type="checkbox" /></span>
</div>
<span id="upd"></span>
As you're dynamically creating a new checkbox when the value changes, you need to delegate the event to your checkbox by assigning it to a non-dynamic ancestor:
$('div[role]').on('change', 'input[type=checkbox]', chg);
Note how I've used change instead of click as this is more appropriate for checkboxes.
In the below snippet I've also changed $(this).is(":checked") to just this.checked.
$('div[role]').on('change', 'input[type=checkbox]', chg);
$('div[role] input[type=text]').on('input', sourceChanged);
function chg() {
var istiki = this.checked;
$('#upd').html(istiki);
}
function sourceChanged() {
$('span', $(this).closest('.input-group')).html('<input type="checkbox">');
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div role="Tiki" class="input-group">
<input type="text" class="form-control" />
<span class="input-group-addon"><input type="checkbox" /></span>
</div>
<span id="upd"></span>
Note also that if you want it to say false you should convert your istiki variable to a string:
$('#upd').html('' + isticki);

copy label text to input

I have tried several ways to achieve this, but somehow nothing works for this.
How can I copy the "label text" of respective Radio Button, which is selected by user into the input field (Result Box) in real time?
HTML -
<ul class="gfield_radio" id="input_4_4">
Radio Buttons:
<br />
<li class="gchoice_4_0">
<input name="input_4" type="radio" value="2" id="choice_4_0" class="radio_s" tabindex="4">
<label for="choice_4_0">Hi</label>
</li>
<li class="gchoice_4_1">
<input name="input_4" type="radio" value="4" id="choice_4_1" class="radio_s" tabindex="5">
<label for="choice_4_1">Hello</label>
</li>
<li class="gchoice_4_2">
<input name="input_4" type="radio" value="3" id="choice_4_2" class="radio_s" tabindex="6">
<label for="choice_4_2">Aloha</label>
</li>
</ul>
<br />
<div class="ginput_container">
Result Box:
<br />
<input name="input_3" id="input_4_3" type="text" value="" class="medium" tabindex="3">
</div>
My attempts:
$('input').change(function() {
if (this.checked) {
var response = $('label[for="' + this.id + '"]').html();
alert(response);
}
// also this:
// if ($("input[type='radio'].radio_s").is(':checked')) {
// var card_type = $("input[type='radio'].radio_s:checked").val();
// alert('card_type');
// }
});
You need to traverse the DOM from the radio which was clicked to find the nearest label element.
$('.radio_s').change(function() {
$('#input_4_3').val($(this).closest('li').find('label').text());
});
Example fiddle
You could also use $(this).next('label') however, that relies on the position of the label element not changing. My first example means the label can be anywhere within the same li as the radio button and it will work.
Try this:
$('.radio_s').click(function() {
$("#input_4_3").val($("input:checked" ).next().text());
});

This is a slightly tricky question to answer well. The structure of your HTML implies that there may be more than one of these structures on the page. So you may have more than one set of radio buttons with a corresponding checkbox.
I have put some working code into a jsFiddle.
I made one change: all the code you had in your question is now in <div class="container">. You would need as many of these as you had groups of radio buttons and checkboxes.
You can then have jQuery code like this:
$('ul.gfield_radio').on('change', 'input[type="radio"]', function () {
var label = $('label[for="' + this.id + '"]');
$(this).closest('.container').find('input.medium').val(label.text());
});
This code is not tied to the id values in this particular bit of HTML, but would work as many times as necessary throughout the page.
Why to depend on third party library when you can achieve it with plain javascript:
<script>
document.addEventListener('DOMContentLoaded', function () {
var a = document.getElementsByName('input_4');
for (var i = 0; i < a.length; i++) {
document.getElementsByName('input_4')[i].addEventListener('change', function () {
showValue(this);
}, false);
}
}, false);
function showValue(element) {
alert(element.parentNode.getElementsByTagName('label')[0].innerHTML)
}
</script>

If Radio Button is Selected Show Div - 8 Radio Buttons / 8 Divs - Can this be simplified?

Basically, I want 8 radio buttons. And if one radio button is selected then a div is shown below. If another button is selected another div is shown. Only one div shown at a time and if no button selected (initially) then no divs shown.
This is my HTML which is fairly standard, I'm not trying to improve this for what I need.
<form id='group'>
<label><input type="radio" name="group1" class="sim-micro-btn"/></label>
<label><input type="radio" name="group1" class="sim-mini-btn"/></label>
<label><input type="radio" name="group1" class="sim-maxi-btn"/></label>
<label><input type="radio" name="group1" class="sim-mega-btn"/></label>
<label><input type="radio" name="group1" class="phone-smart-micro-btn"/></label>
<label><input type="radio" name="group1" class="phone-smart-mini-btn"/></label>
<label><input type="radio" name="group1" class="phone-smart-btn"/></label>
<label><input type="radio" name="group1" class="phone-smart-maxi-btn"/></label>
</form>
<div class="billpay-internet-add-ons">
<div class="sim-micro-desktop">sim-micro</div>
<div class="sim-mini-desktop">sim-mini</div>
<div class="sim-maxi-desktop">sim-maxi</div>
<div class="sim-mega-desktop">sim-mega</div>
<div class="phone-smart-micro-desktop">phone-smart-micro</div>
<div class="phone-smart-mini-desktop">phone-smart-mini</div>
<div class="phone-smart-desktop">phone-smart</div>
<div class="phone-smart-maxi-desktop">phone-smart-maxi</div>
</div>
However this is my script and it seems fairly hectic and I'm wondering before I move on is there a way to do this a bit more simple?
$(document).ready(function(){
$('.sim-micro-desktop').hide();
$('.sim-mini-desktop').hide();
$('.sim-maxi-desktop').hide();
$('.sim-mega-desktop').hide();
$('.phone-smart-micro-desktop').hide();
$('.phone-smart-mini-desktop').hide();
$('.phone-smart-desktop').hide();
$('.phone-smart-maxi-desktop').hide();
$('form#group').click(function(){
if($('.sim-micro-btn').is(":checked")){
$('.sim-micro-desktop').show();
} else {
$('.sim-micro-desktop').hide();
}
if($('.sim-mini-btn').is(":checked")){
$('.sim-mini-desktop').show();
} else {
$('.sim-mini-desktop').hide();
}
if($('.sim-maxi-btn').is(":checked")){
$('.sim-maxi-desktop').show();
} else {
$('.sim-maxi-desktop').hide();
}
if($('.sim-mega-btn').is(":checked")){
$('.sim-mega-desktop').show();
} else {
$('.sim-mega-desktop').hide();
}
if($('.phone-smart-micro-btn').is(":checked")){
$('.phone-smart-micro-desktop').show();
} else {
$('.phone-smart-micro-desktop').hide();
}
if($('.phone-smart-mini-btn').is(":checked")){
$('.phone-smart-mini-desktop').show();
} else {
$('.phone-smart-mini-desktop').hide();
}
if($('.phone-smart-btn').is(":checked")){
$('.phone-smart-desktop').show();
} else {
$('.phone-smart-desktop').hide();
}
if($('.phone-smart-maxi-btn').is(":checked")){
$('.phone-smart-maxi-desktop').show();
} else {
$('.phone-smart-maxi-desktop').hide();
}
});
});
Firstly put shared classes on both the radio buttons and the div elements which show the content. In my example I've used trigger and content respectively. Then add a data attribute to the radio to identify which div should be shown on click.
Shortened example:
<form id='group'>
<label>
<input type="radio" name="group1" class="sim-micro-btn trigger" data-rel="sim-micro-desktop" />
</label>
</form>
<div class="billpay-internet-add-ons">
<div class="sim-micro-desktop content">sim-micro</div>
</div>
Then you only need 1 click handler like this:
$(document).ready(function(){
$('.trigger').click(function() {
$('.content').hide();
$('.' + $(this).data('rel')).show();
});
});
You can also then use CSS to hide the div elements without jQuery - styling should always be done in CSS anyway as it's a much better separation of concerns.
.content {
display: none;
}
Example fiddle
You can hide the div elements using CSS:
.billpay-internet-add-ons div {
display: none;
}
Then you can use the className of the target to determine which div to show, hiding all sibling elements:
$('form#group').click(function(e) {
var className = e.target.className.replace('btn', 'desktop');
$('.' + className).show().siblings().hide();
});
Here's a fiddle
use html5 data attribute)(i.e data-mappingclass ) pointing to corresponding div you need to show. add same class to all radio button(ie radioClass).
HTML
<label><input type="radio" name="group1" class="radioClass sim-micro-btn" data-mappingclass="sim-micro-desktop"/></label>
<label><input type="radio" name="group1" class="radioClass sim-mini-btn" data-mappingclass="sim-mini-desktop"/></label>
... //same for others
JS
$('.radioClass').click(function() {
$('.billpay-internet-add-ons div').hide();
if(this.checked){
$('.' + $(this).data('mappingclass').show();
}
});
You could use selectors to reduce the number of lines of code here.
$('.sim-micro-desktop').hide();
$('.sim-mini-desktop').hide();
$('.sim-maxi-desktop').hide();
$('.sim-mega-desktop').hide();
$('.phone-smart-micro-desktop').hide();
$('.phone-smart-mini-desktop').hide();
$('.phone-smart-desktop').hide();
$('.phone-smart-maxi-desktop').hide();
Could be shortened to:
$('.billpay-internet-add-ons div').hide();
This uses the parent element to group those elements you want to hide, rather than repeating the request for each one.
Similarly, you can use your naming convention to map the items to the elements to show and hide - here is the full working example:
$(document).ready(function(){
$('.billpay-internet-add-ons div').hide();
$('form#group').click(function(){
$('#group input').each(function() {
var item = $(this);
var isChecked = item.is(':checked');
var name = item.attr('class').replace("-btn", "-desktop");
if (isChecked) {
$('.' + name).show();
} else {
$('.' + name).hide();
}
});
});
});
This example is purely based on your HTML without any changes. See it working here.
You could simplify this further if you didn't need to transform the names. You could use a data-attribute instead of changing the class names to do this.
var $billpay= $('.billpay-internet-add-ons');
$billpay.find("div").hide();
$("#group input:radio").click(function(){
$billpay.find("div").hide();
$billpay.find("div:eq("+$(this).parent().index()+")").show();
});
http://jsfiddle.net/KaF77/2/
I simplified it some four you. Basically you look which index the radio clicked has and then show a div with the same index. So the position of the divs has to match the radios.
Your HTML is the same as before.
Your CSS:
.billpay-internet-add-ons > div {
display:none;
}
All your Javascript:
$(document).ready(function(){
$('form#group').click(function(e)
{
$('.billpay-internet-add-ons > div').hide();
$('form#group input[type="radio"]').each(function(index)
{
if($(this).is(':checked'))
{
$('.billpay-internet-add-ons > div:eq(' + index + ')').show();
}
});
});
});
jsFiddle Demo: http://jsfiddle.net/cfSXY/
You can firstly have everything hidden by default (except one form maybe) using CSS, which gets rid of this:
$('.sim-micro-desktop').hide();
$('.sim-mini-desktop').hide();
$('.sim-maxi-desktop').hide();
$('.sim-mega-desktop').hide();
$('.phone-smart-micro-desktop').hide();
$('.phone-smart-mini-desktop').hide();
$('.phone-smart-desktop').hide();
$('.phone-smart-maxi-desktop').hide();
This has a negative implication for users without javascript, if you're worried - they'll never be able to see the other forms.
Next, only one radio can be checked, so just find out which one it is using:
$('input[name=group1]:checked);
But why would you do that, so you have the radios have a click handler more like:
$('#group input[type="radio"').click(function(){
//code to show/hide form
});
Now you have a choice as to how you link your radio buttons to the different forms one way could be to use the data attribute, so you define your radios like so:
<label><input type="radio" name="group1" class="phone-smart-maxi-btn" data-form="phone-smart-maxi-desktop"/></label>
Which you can access like so:
$('input[name=group1]:checked).data("form");
Now all you need to do is hide the div that was already showing, but that can be achieved with a similar use of the data attribute or by using the :visible selector.

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.
Here's the fiddle: http://jsfiddle.net/KqtS7/5/
