I have a list of checkboxes like so:
<div class="checkbox-list">
<label><input type="checkbox" value="" /> All items</label><br />
<label><input type="checkbox" value="1" /> First item</label><br />
<label><input type="checkbox" value="2" /> Second item</label><br />
<label><input type="checkbox" value="3" /> Third item</label><br />
<label><input type="checkbox" value="4" /> Forth Checkbox</label>
</div>
The behavior I am looking for is if I select the first checkbox in this div (.checkbox-list input[type=checkbox]:first) all other checkboxes after is checked off. Likewise if I select any other than the first, the first one is deselected.
I am struggling on how to check if the first one is clicked on?
$(".checkbox-list").on("change", "input[type=checkbox]", function () {
if ($(this).first()) { // <- not working - how do I know if I clicked the first one?
$("input[type=checkbox]:checked", ".checkbox-list").not(this).prop("checked", false);
$(this).prop("checked", true);
} else {
// Uncheck first checkbox
}
});
Here is a fiddle if you wish to play around: http://jsfiddle.net/4c7aubqL/1/
jsBin demo
$(".checkbox-list").on("change", ":checkbox", function() {
var $all = $(".checkbox-list").find(":checkbox");
var $first = $all.eq(0);
if ($first.is(":checked")) {
$all.not(this).prop("checked", false);
}
});
You should be using radio buttons, not checkboxes. That will do exactly what you want, with no additional effort on your part. Even if you succeed in what you are trying to do, the user interface will look wrong.

i use this code to show some text (Checked) when click on 1 or more checkboxes.
I use the on because the checkboxes are dynamically created.
It seems that only IE Edge can not deal with it. I have to click twice on a checkbox to show the Checked text. In all other browsers it works immediately.
Really don't know what is wrong with the code
<input type="checkbox" class="rafcheckbox" value="1" />
<input type="checkbox" class="rafcheckbox" value="2" />
<input type="checkbox" class="rafcheckbox" value="3" />
<div class="cb-buttons" style="display:none">Checked</div>
<script>
$(document).on('click','.rafcheckbox',function() {
var $checkboxes = $('.rafcheckbox').change(function() {
var anyChecked = $checkboxes.filter(':checked').length != 0;
$(".cb-buttons").toggle(anyChecked);
});
});
</script>
Fiddle: https://jsfiddle.net/g5tp4kjm/
Since you already have the delegate for the elements, just change it to a change event handler.
Inside that logic, toggle the hide class, but force it to have the hide class if no elements are checked.
$(document).on('change','.rafcheckbox',function() {
$('.cb-buttons').toggleClass('hide', $('.rafcheckbox:checked').length < 1);
});
.hide { display: none; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" class="rafcheckbox" value="1" />
<input type="checkbox" class="rafcheckbox" value="2" />
<input type="checkbox" class="rafcheckbox" value="3" />
<div class="cb-buttons hide">Checked</div>
Lets try it another way.
$(document).on('click','.rafcheckbox',function() {
if($('.rafcheckbox').is(':checked'))
{
//do whatever you want
}
else
{
//do the opposite
}
});
I am trying to create a filter using checkboxes. I need to only have one checkbox checked at a time. How do I do this?
Scenario: The page has a catalog of watches. The user wants to filter the watches according to for men or for women
Here is my code:
$("#filter-options :checkbox").click(function()
{
$(".collection-wrapper .strap-wrapper").hide();
$("#filter-options :checkbox:checked").each(function()
{
$("." + $(this).val()).fadeIn();
});
if($('#filter-options :checkbox').filter(':checked').length < 1)
{
$(".collection-wrapper .strap-wrapper").fadeIn();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<h3>Filter Items</h3>
<ul id="filter-options">
<li><input type="checkbox" value="filter_man" data-filter_id="man"> Man</li>
<li><input type="checkbox" value="filter_woman" data-filter_id="woman"> Woman</li>
</ul>
<div class="collection-wrapper">
<div class="strap-wrapper filter_man">
<h2>man</h2>
<p></p>
</div>
<div class="strap-wrapper filter_woman">
<h2>woman</h2>
<p></p>
</div>
<div class="strap-wrapper filter_man filter_woman">
<h2>man / woman</h2>
<p></p>
</div>
<div class="strap-wrapper filter_woman">
<h2>woman</h2>
<p></p>
</div>
</div>
Thanks in advance!
Checkboxes are used for selecting multiple values of choices. What you need is Radio Buttons. They are used exactly for this purpose. One can select only one radio button at a time. So replace your code with:
<ul id="filter-options">
<li><input type="radio" name="filter" value="filter_man" data-filter_id="man"> Man</li>
<li><input type="radio" name="filter" value="filter_woman" data-filter_id="woman"> Woman</li>
</ul>
See an example here: http://www.w3schools.com/tags/tryit.asp?filename=tryhtml5_input_type_radio
Radio buttons are what you are looking for ;)
take at look at these links:
jQuery api demo
Fiddle example
HTML:
<form id="myForm">
<input type="radio" name="myRadio" value="1" /> 1 <br />
<input type="radio" name="myRadio" value="2" /> 2 <br />
<input type="radio" name="myRadio" value="3" /> 3 <br />
</form>
JS
$('#myForm input').on('change', function() {
alert($('input[name="myRadio"]:checked', '#myForm').val());
});
You could use radio buttons or you could do something like:
$('input[type=checkbox]').change(function(){
if ($('input[type=checkbox]:checked').length > 1) {
this.checked = false;
}
})
You could just use radio buttons, but if you want to do it with checkboxes, solution is pretty simple.
When you click on one of the checkboxes, select all the checkboxes and remove "checked" state, and then just add checked on clicked checkbox
Something like this:
// On checkbox click
$("#filter-options input[type=checkbox]").click(function(event) {
// Uncheck all checkboxes
$("#filter-options input[type=checkbox]").prop("checked", false);
// Check that one that you clicked
$(this).prop("checked", true)
});
i have two checkboxes. i want this algorithm happen:
if i check checkbox1 i want checkbox 2 to be uncheck,
then if i check checkbox2 i want checkbox1 to be unchecked.
therefore, i need to select one checkbox only.
and i want this in jquery.
thank you..
HTML
<input type="checkbox" name="checkme" id="cc1">Check Me1</input>
<input type="checkbox" name="checkme" id="cc2">Check Me2</input>
JavaScript
$('#cc1').change(function(){
var c = this.checked ? $('#cc1').prop('checked', true) : $('#cc2').prop('checked', false);
});
$('#cc2').change(function(){
var c = this.checked ? $('#cc2').prop('checked', true) : $('#cc1').prop('checked', false);
});
http://jsfiddle.net/z4nKW/
$('#cc1').change(function(){
$('#cc2').prop('checked', !$(this).prop('checked'));
});
$('#cc2').change(function(){
$('#cc1').prop('checked', !$(this).prop('checked'));
});
Maybe radio buttons are better fit for such case.
THE DEMO>
this, by itself is a javascript element and therefor doesn't have a property "checked".
You need to wrap it in jQuery like so:
$(this).checked
Radio buttons ensure that only one item is selected:
<form>
<input type="radio" name="sex" value="male">
<input type="radio" name="sex" value="female">
</form>
source (w3schools)
Use radio buttons:
<input type="radio" name="option">Option 1</input>
<input type="radio" name="option">Option 2</input>
you can also do this
Html:
<input type="checkbox" name="checkme" class="check" id="cc1">Check Me1</input>
<input type="checkbox" name="checkme" class="check" id="cc2">Check Me2</input>
JQuery
$(".check").each(function()
{
$(this).change(function()
{
$(".check").prop('checked',false);
$(this).prop('checked',true);
});
});
I have to control the checked status a list of checkboxes from another checkbox.
HTML:
<input id="readall" name="readall" type="checkbox" value="1">
<div id="permGrid">
<input id="recipe.read" name="recipe.read" type="checkbox" value="1" rel="read">
<input id="group.read" name="group.read" type="checkbox" value="1" rel="read">
<input id="ingredients.read" name="ingredients.read" type="checkbox" value="1" rel="read">
</div>
JS:
$('#readall').click(function()
{
var checkStatus = $(this).is(':checked');
var checkboxList = $('#permGrid input[rel="read"]');
$(checkboxList).attr('rel', 'read').each(function(index)
{
if(checkStatus == true)
{
$(this).attr('checked', 'checked');
console.log($(this).attr('checked'));
}
else
{
$(this).removeAttr('checked').reload();
console.log($(this).attr('checked'));
}
});
});
The above code seems fine but the check/uncheck works only for the first time. But when I click the main checkbox second time, it doesn't change the status of other checkboxes into 'checked'. Is there anything I need to do?
I found something similar here. I compared the code and mine and this code is somewhat similar but mine doesn't work.
Try using prop, and shorten the code alot like this
$('#readall').click(function () {
var checkboxList = $('#permGrid input[rel="read"]')
checkboxList.prop('checked', this.checked);
});
DEMO
You can't use a method .reload like this
$(this).removeAttr('checked').reload();
// returns Uncaught TypeError: Object #<Object> has no method 'reload'
Remove it, and it will work.
JSFiddle
Use a class for all the checkboxes which you need to change on click of some checkbox. Like:
<input id="recipe.read" class="toChange" name="recipe.read" type="checkbox" value="1" rel="read" />
I have added a class="toChange" to all the checkboxes except the first one.
<input id="readall" name="readall" type="checkbox" value="1">
<div id="permGrid">
<input id="recipe.read" class="toChange" name="recipe.read" type="checkbox" value="1" rel="read" />
<input id="group.read" class="toChange" name="group.read" type="checkbox" value="1" rel="read" />
<input id="ingredients.read" class="toChange" name="ingredients.read" type="checkbox" value="1" rel="read" />
</div>
Then use the following script:
$('#readall').click(function(){
var checkStatus = $(this).is(':checked');
if(checkStatus){
$(".toChange").attr('checked', 'checked');
}
else{
$(".toChange").removeAttr('checked')
}
});

I have a form and group of checkboxes in it. (These checkboxes are dynamically created but I dont think it is important for this question). The code that generates them looks like this (part of the form):
<div id="ScrollCB">
<input type="checkbox" name="ALL" value="checked" checked="checked">
All (if nothing selected, this is default) <br>
<c:forEach items="${serviceList}" var="service">
<input type="checkbox" name="${service}" value="checked"> ${service} <br>
</c:forEach>
</div>
What I want to do is control, whether the checkbox labeled "ALL" is checked and if yes - check all other checkboxes (and when unchecked, uncheck them all).
I tried doing this with javascript like this (found some tutorial), but it doesnt work (and Im real newbie in javascript, no wonder):
<script type="text/javascript">
$ui.find('#ScrollCB').find('label[for="ALL"]').prev().bind('click',function(){
$(this).parent().siblings().find(':checkbox').attr('checked',this.checked).attr('disabled',this.checked);
}); });
</script>
Could you tell me some simple approach how to get it work? Thanks a lot!

Thanks to #Ashish, I have expanded it slightly to allow the "master" checkbox to be automatically checked or unchecked, if you manually tick all the sub checkboxes.
FIDDLE
HTML
<label><input type="checkbox" name="sample" class="selectall"/>Select all</label>
<div id="checkboxlist">
<label><input type="checkbox" class="justone" name="sample[]"/>checkbox1</label><br/>
<label><input type="checkbox" class="justone" name="sample[]"/>checkbox2</label><br />
<label><input type="checkbox" class="justone" name="sample[]"/>checkbox3</label><br />
<label><input type="checkbox" class="justone" name="sample[]"/>checkbox4</label><br />
</div>
SCRIPT
$('.selectall').click(function() {
if ($(this).is(':checked')) {
$('input:checkbox').prop('checked', true);
} else {
$('input:checkbox').prop('checked', false);
}
});
And now add this to manage the master checkbox as well...
$("input[type='checkbox'].justone").change(function(){
var a = $("input[type='checkbox'].justone");
if(a.length == a.filter(":checked").length){
$('.selectall').prop('checked', true);
}
else {
$('.selectall').prop('checked', false);
}
});
Add extra script according to your checkbox group:
<script language="JavaScript">
function selectAll(source) {
checkboxes = document.getElementsByName('colors[]');
for(var i in checkboxes)
checkboxes[i].checked = source.checked;
}
</script>
HTML Code:
<input type="checkbox" id="selectall" onClick="selectAll(this,'color')" />Select All
<ul>
<li><input type="checkbox" name="colors[]" value="red" />Red</li>
<li><input type="checkbox" name="colors[]" value="blue" />Blue</li>
<li><input type="checkbox" name="colors[]" value="green" />Green</li>
<li><input type="checkbox" name="colors[]" value="black" />Black</li>
</ul>
use this i hope to help you i know that this is a late answer but if any one come here again
$("#all").change(function () {
$("input:checkbox").prop('checked', $(this).prop("checked"));
});
Only in JavaScript with auto check/uncheck functionality of master when any child is checked/unchecked.
function FnCheckAll()
{
var ChildChkBoxes = document.getElementsByName("ChildCheckBox");
for (i = 0; i < ChildChkBoxes.length; i++)
{
ChildChkBoxes[i].checked = document.forms[0].CheckAll.checked;
}
}
function FnCheckChild()
{
if (document.forms[0].ChildCheckBox.length > document.querySelectorAll('input[name="ChildCheckBox"]:checked').length)
document.forms[0].CheckAll.checked = false;
else
document.forms[0].CheckAll.checked = true;
}
Master CheckBox:
<input type="checkbox" name="CheckAll" id="CheckAll" onchange="FnCheckAll()" />
Child CheckBox:
<input type="checkbox" name="ChildCheckBox" id="ChildCheckBox" onchange="FnCheckChild()" value="#employee.Id" />```
You can use jQuery like so:
jQuery
$('[name="ALL"]:checkbox').change(function () {
if($(this).attr("checked")) $('input:checkbox').attr('checked','checked');
else $('input:checkbox').removeAttr('checked');
});
A fiddle.
var selectedIds = [];
function toggle(source) {
checkboxes = document.getElementsByName('ALL');
for ( var i in checkboxes)
checkboxes[i].checked = source.checked;
}
function addSelects() {
var ids = document.getElementsByName('ALL');
for ( var i = 0; i < ids.length; i++) {
if (ids[i].checked == true) {
selectedIds.push(ids[i].value);
}
}
}
In HTML:
Master Check box <input type="checkbox" onClick="toggle(this);">
Other Check boxes <input type="checkbox" name="ALL">
You can use the :first selector to find the first input and bind the change event to it. In my example below I use the :checked state of the first input to define the state of it's siblings. I would also suggest to put the code in the JQuery ready event.
$('document').ready(function(){
$('#ScrollCB input:first').bind('change', function() {
var first = $(this);
first.siblings().attr('checked', first.is(':checked'));
});
});
I am not sure why you would use a label when you have a name on the checkbox. Use that as the selector. Plus your code has no labels in the HTML markup so it will not find anything.
Here is the basic idea
$(document).on("click",'[name="ALL"]',function() {
$(this).siblings().prop("checked",this.checked);
});
if there are other elements that are siblings, than you would beed to filter the siblings
$(document).on("click",'[name="ALL"]',function() {
$(this).siblings(":checkbox").prop("checked",this.checked);
});
