JQuery select label of selected checkboxes - javascript

When I click a button I want to get the value from each of the checked check boxes. I really just want to populate an array with all the check boxes that are checked.
I started a simplified example here: http://jsfiddle.net/kralco626/JvAdg/1/
The actual code is more like this:
var dataList = new Array(10);
dataList[0] = "Delete";
dataList[1] = LD_LicenseNumber.val();
dataList[2] = $("#LDOperatingCompanies input:checked").val();
And aspx code:
<div id="LDOperatingCompanies">
<input type="checkbox" value="o1" id="o1" name="LDOperatingCompanies" /><label for="o1">o1</label>
<input value="o2" type="checkbox" id="o2" name="LDOperatingCompanies" /><label for="o2">o2</label>
<input value="o3" value="o1" type="checkbox" id="o3" name="LDOperatingCompanies" /><label for="o3">o3</label>
</div>
Thanks!

here is an update to your fiddle that puts all checked boxes into an array Example
HTML
<div id="LDOperatingCompanies">
<input type="checkbox" id="o1" name="LDOperatingCompanies" /><label for="o1">o1</label>
<input type="checkbox" id="o2" name="LDOperatingCompanies" /><label for="o2">o2</label>
<input type="checkbox" id="o3" name="LDOperatingCompanies" /><label for="o3">o3</label>
</div>
<input type="button" id="btn" value="alert checked boxes" />
JavaScript
var checks = [];
$('#btn').click(function(e) {
$(':checked').each(function(index, item) {
checks.push( item );
});
if(checks.length == 0) alert('nothing checked');
else alert(checks);
});

check box if select one un-select all other

Ok, so i have a list of check boxes 1, 2, 3, 4 and 5. I would like the function to select 2, 3, 4 and 5 but if 1 is selected then un-select 2, 3, 4 and 5, once 2 to 5 are un-selected display a message in a div.
So far I can select 1 and one of the others... and the message comes on selection of 1
problem 1
I cant un-select 2 to 5 once 1 is selected
problem 2
The message is displayed on page load even if the box is un-selected.
HTML
<input type="checkbox" class="" value="checkbox" name="CheckboxGroup1" id="boxchecked" />
one <br/>
<input type="checkbox" class="check" />
two <br/>
<input type="checkbox" class="check" />
three <br/>
<input type="checkbox" class="check" />
four <br/>
<input type="checkbox" class="check" />
five
<div id="hidden">Two to five can not be selected whilst you have one selected</div>
JavaScript
$('input.check').on('change', function() {
$('input.check').not(this).prop('checked', false);
});
$(document).ready(function(){
$("#boxchecked").click(function ()
{
if ($("#boxchecked").is(':checked'))
{
$("#hidden").show();
}
else
{
$("#hidden").hide();
}
});
});
$('input[name=CheckboxGroup1]').attr('checked', false);
Here is what I propose. How about giving the checkbox that can only be singly checked a class, and the others another class?
Hope it helps.
$('input[type="checkbox"]').on('click', function() {
if($(this).hasClass('singlecheck')) {
if($('input.multicheck').is(":checked")) {
$('#warning').show();
}
$('input.multicheck').prop('checked', false);
} else {
$('input.singlecheck').prop('checked', false);
$('#warning').hide();
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" class="singlecheck" value="one" name="CheckboxGroup1" id="boxchecked" />
one <br/>
<input type="checkbox" class="multicheck" value="two"/>
two <br/>
<input type="checkbox" class="multicheck" value="three"/>
three <br/>
<input type="checkbox" class="multicheck" value="four"/>
four <br/>
<input type="checkbox" class="multicheck" value="five"/>
five
<div id="warning" style="display:none">Two to five can not be selected whilst you have one selected</div>
What you can do is that you can disable the checkboxes 2-5 as soon as the checkbox 1 is checked and then show the message. If one is not checked your can enable the other checkboxes and hide the message as:
$('input[type="checkbox"]').on('change', function(){
if($('#boxchecked').prop('checked')) {
$('.check').attr('disabled', true);
$('#hidden').show();
}
else {
$('.check').removeAttr('disabled');
$('#hidden').hide();
}
})
#hidden {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" class="" value="checkbox" name="CheckboxGroup1" id="boxchecked" />
one <br/>
<input type="checkbox" class="check" />
two <br/>
<input type="checkbox" class="check" />
three <br/>
<input type="checkbox" class="check" />
four <br/>
<input type="checkbox" class="check" />
five
<div id="hidden">Two to five can not be selected whilst you have one selected</div>
i think you want this type fuctionality :
jQuery
var box = null;
$(document).ready(function() {
$(".check").click(function() {
box = this.id;
$(".check").each(function() {
if ( this.id == box )
{
this.checked = true;
//$("#hidden").show();
var cval =$(this).val();
document.getElementById("get").innerHTML =cval;
}
else
{
this.checked = false;
};
});
});
});
HTml Code
<input type="checkbox" class="check" value="one" name="CheckboxGroup1" id="one" />
one <br/>
<input type="checkbox" class="check" id="two" value="two" />
two <br/>
<input type="checkbox" class="check" id="three" value="three" />
three <br/>
<input type="checkbox" class="check" id="four" value="four" />
four <br/>
<input type="checkbox" class="check" id="five" value="five" />
five
<div id="hidden">This checkbox number is <label id="get">0</label></div>
I hope its usefull for you
To un-select check box 2-5, you can use something like this:
$('input[name="CheckboxGroup1"]').on('click', function() {
if ($(this).is(":checked")) {
$('input.check').prop('checked', false);
}
})
For message to be hidden initially, you can have an initialization function that will set/reset UI states to default
function initUI() {
$('input[name=CheckboxGroup1]').attr('checked', false);
$('#hidden').hide();
}
Sample Fiddle
Also, for cases where you have if...else to toggle visibility of a field, you should use .toggle(VisibilityValue)
$("#boxchecked").click(function() {
$("#hidden").toggle($("#boxchecked").is(':checked'))
});

How to move checkmark through the cheboxlist?

So i have checkboxlist
<input type="checkbox" name="colorc" value="black" />Black<br/><br>
<input type="checkbox" name="colorc" value="brown" />Brown<br/><br>
<input type="checkbox" name="colorc" value="white" />White<br/><br>
<input type="button" id="btnClick" value="Color Change"></button>
and when i press button, checkmark moves to next checkbox, the same i want if we have two checkmarks, but without using JQuery, clear JS. Thanks
I guess this would do:
document.getElementById("btnClick").onclick = function(){
var checkBoxes = document.getElementsByName("colorc");
var checked = checkBoxes[checkBoxes.length - 1].checked;
for(var i = checkBoxes.length-1; i > 0; --i){
checkBoxes[i].checked = checkBoxes[i-1].checked;
}
checkBoxes[0].checked = checked;
}
Demo: http://jsfiddle.net/t231c0ga/1/
The current checked input can be selected as:
input[name=colorc]:checked
The next input can be gotten using the general sibling selector (~):
input[name=colorc]:checked ~ input[name=colorc]
Change your inputs from checkboxes to radio buttons, and use this code. If there's no next input, it defaults to the first input:
document.getElementById('btnClick')
.addEventListener('click',function() {
var next=
document.querySelector(
'input[name=colorc]:checked ~ input[name=colorc]'
) ||
document.querySelector('input[name=colorc]');
next.checked= true;
});
<input type="radio" name="colorc" value="black" checked/>Black<br/><br>
<input type="radio" name="colorc" value="brown" />Brown<br/><br>
<input type="radio" name="colorc" value="white" />White<br/><br>
<input type="button" id="btnClick" value="Color Change"></button>

How to select all checkbox using jquery or javascript? [duplicate]

This question already has answers here:
How to select all checkboxes with jQuery?
(15 answers)
Closed 8 years ago.
I have multiple checkboxes , there is a checkbox with select all name, now i want that when some tick
the select all checkbox, then all the checkbox must be selected. I think this will be in jquery.
any tutorial link or codes with hints would be appreciated.the code snip is under...
<input type="checkbox" value="">Select All<br/>
<input type="checkbox" value="">A<br/>
<input type="checkbox" value="">B<br/>
<input type="checkbox" value="">C<br/>
<input type="checkbox" value="">D<br/>
<input type="checkbox" value="">E<br/>
<input type="checkbox" value="">F<br/>
<input type="checkbox" value="">G<br/>
<input type="checkbox" value="">H<br/>
This should check all checkboxes when you check the "Select All" one, and also uncheck all checkboxes when you uncheck it.
$("#selectAll").click(function () {
$(":checkbox").not(this).prop("checked", $(this).is(":checked"));
});
If you don't want the uncheck behavior:
$("#selectAll").click(function () {
if ($(this).is(":checked")) {
$(":checkbox").not(this).prop("checked", true);
}
});
But of course, you must identify it. Do it by adding the id="selectAll" attribute (or any other id you wish, just make sure you change the JavaScript code as well):
<input type="checkbox" value="" id="selectAll">Select All<br/>
<input type="checkbox" value="">A<br/>
<input type="checkbox" value="">B<br/>
<input type="checkbox" value="">C<br/>
<input type="checkbox" value="">D<br/>
<input type="checkbox" value="">E<br/>
<input type="checkbox" value="">F<br/>
<input type="checkbox" value="">G<br/>
<input type="checkbox" value="">H<br/>
<input type="checkbox" id="exp" />Tick All Checkbox<br/>
<input type="checkbox" value="demo1" class="subchkbox"/>No 1<br/>
<input type="checkbox" value="demo2" class="subchkbox"/>No 2<br/>
<input type="checkbox" value="demo3" class="subchkbox"/>No 3<br/>
<input type="checkbox" value="demo4" class="subchkbox"/>No 4<br/>
<input type="checkbox" value="demo5" class="subchkbox"/>No 5<br/>
<sctipt type="text/javascript">
/*Include the jquery library 1.9.1*/
$(document).ready(function() {
$('#exp').click(function(event) {
if(this.checked) {
$('.subchkbox').each(function() {
this.checked = true;
});
}else{
$('.subchkbox').each(function() {
this.checked = false;
});
}
});
});
[the fiddle is here][1]
Using jQuery :
$("input[type=checkbox]").prop({ checked : true })
JSFiddle
Using pure JavaScript :
var inputs = document.querySelectorAll('input[type=checkbox]')
Object.keys(inputs).forEach(function(i){
inputs[i].checked = true
})
JSFiddle
$("checkboxContainer").find("input[type='checkbox']").each(function() {
$(this).prop("checked", true);
});
I think using .find() is faster when selecting multiple elements.
If you want to do this in plain JS, it's also pretty simple.
You just have to loop through all of the inputs and set checked to true (or false), which isn't very efficient.
document.getElementById("all").addEventListener("change", function() {
if (this.checked) {
var boxes = document.getElementsByTagName("input");
for (var i = 0; i < boxes.length; i++) {
if (boxes[i].type === "checkbox") {
boxes[i].checked = true;
}
}
} else {
var boxes = document.getElementsByTagName("input");
for (var i = 0; i < boxes.length; i++) {
if (boxes[i].type === "checkbox") {
boxes[i].checked = false;
}
}
}
});
<input type="checkbox" value="" id="all">Select All
<br/>
<input type="checkbox" value="">A
<br/>
<input type="checkbox" value="">B
<br/>
<input type="checkbox" value="">C
<br/>
<input type="checkbox" value="">D
<br/>
<input type="checkbox" value="">E
<br/>
<input type="checkbox" value="">F
<br/>
<input type="checkbox" value="">G
<br/>
<input type="checkbox" value="">H
<br/>
Derived from the current answer marked as correct, it can all be much simpler:
$(document).ready(function()
{
$('#exp').click(function(event)
{
$('.subchkbox').prop({
checked: $(this).prop('checked')
});
});
});

Checkboxes group

Hello I've got a question about chechbox.
This code checked/unchecked all checkboxes if first one is checked/unchecked.
But I want to do something else with that. I want to add function that, if all of checkboxes are checked then the first one too, but when one or more of the checkboxes are unchecked then first one will be unchecked.
<input class="checkbox" onClick=Show("checkbox") type="checkbox" name="checkboxAll" value="all">
<input class="checkbox" type="checkbox" name="checkboxname1" value="1">
<input class="checkbox" type="checkbox" name="checkboxname2" value="2">
<input class="checkbox" type="checkbox" name="checkboxname3" value="3">
js code:
function Show( a ) {
if ( $("."+a).attr('checked') == true )
$("."+a).attr('checked', true);
else
$("."+a).attr('checked', false);
}
change your child element class names and call it in your show function. It will do the work for you. It is not working right now as expected as the class names are same for 1st one also as the others.
I have changed the names of you checkBoxes a bit, but from what I can understand in your question, this will work:
<input id="first" onClick="Show();" type="checkbox" name="checkboxAll" value="all">
<input class="checkbox" onClick="check();" type="checkbox" name="checkboxname1" value="1">
<input class="checkbox" onClick="check();" type="checkbox" name="checkboxname2" value="2">
<input class="checkbox" onClick="check();" type="checkbox" name="checkboxname3" value="3">
and the js:
function Show() {
if ($('#first').is(':checked')){
$(".checkbox").prop('checked', true);
}
else{
$(".checkbox").prop('checked', false);
}
}
function check(){
allChecked = true;
$(".checkbox").each(function(){
if (!$(this).is(':checked')){
allChecked = false;
}
});
if (allChecked){
$("#first").prop('checked', true);
}
else{
$("#first").prop('checked', false);
}
}
It is better to use the "prop" than the "attr" function, see here: How to check whether a checkbox is checked in jQuery?
Try this
$(function(){
$('input[name="checkboxAll"]').change(function(){
$('input[name^="checkboxname"]').prop("checked",$(this).is(':checked'))
});
$('input[name^="checkboxname"]').change(function(){
var a=$('input[name^="checkboxname"]').length;
if( $('input[name^="checkboxname"]').filter(":checked").length==a){
$('input[name="checkboxAll"]').prop("checked",true)}
else
{
$('input[name="checkboxAll"]').prop("checked",false)
}
});
});
DEMO
Include jQuery and copy and paste this code
Its working.......
<script>
$(function(){
$('#select_all_').click(function(){
if($('#select_all_').is(':checked')){
$(".check_").attr ( "checked" ,"checked" );
}
else
{
$(".check_").removeAttr('checked');
}
});
$('.check_').click(function(){
$.each($('.check_'),function(){
if(!$(this).is(':checked'))
$('#select_all_').attr('checked',false);
});
});
});
</script>
<input type="checkbox" name="chkbox" id="select_all_" value="1" />
<input type="checkbox" name="chkbox" class="check_" value="Apples" />
<input type="checkbox" name="chkbox" class="check_" value="Bananas" />
<input type="checkbox" name="chkbox" class="check_" value="Apples" />
<input type="checkbox" name="chkbox" class="check_" value="Bananas" />

How can I make a group of checkboxes mutually exclusive?

I have to make mutually exculsive checkboxes. I have come across numerous examples that do it giving example of one checkbox group.
One example is at http://blog.schuager.com/2008/09/mutually-exclusive-checkboxes-with.html.
In my case, I have many checkbox groups on the same page, so I want it to work like this example.
An asp.net codebehind example is here, but I want to do it in client side code.
How can I do this in JavaScript?
i have decided to use the ajax mutually exclusive checkbox extender.
The solutions given so far are basically based on radio buttons.
This link really helped me..http://www.asp.net/ajax/videos/how-do-i-use-the-aspnet-ajax-mutuallyexclusive-checkbox-extender
Using Mutual Checkboxes when there is Radio button is a bad idea but still you can do this as follows
HTML
<div>
Red: <input id="chkRed" name="chkRed" type="checkbox" value="red" class="checkbox">
Blue: <input id="chkBlue" name="chkBlue" type="checkbox" value="blue" class="checkbox">
Green: <input id="chkGreen" name="chkGreen" type="checkbox" value="green" class="checkbox">
</div>
<div>
Mango: <input id="chkRed" name="chkMango" type="checkbox" value="Mango" class="checkbox">
Orange: <input id="chkBlue" name="chkOrange" type="checkbox" value="Orange" class="checkbox">
Banana: <input id="chkGreen" name="chkBanana" type="checkbox" value="Banana" class="checkbox">
</div>
Jquery
$('div .checkbox').click(function () {
checkedState = $(this).attr('checked');
$(this).parent('div').children('.checkbox:checked').each(function () {
$(this).attr('checked', false);
});
$(this).attr('checked', checkedState);
});
And here is fiddle
Like I said in my comment, you should really use <radio> elements for this. Give them the same name and they work almost the same way:
<label><input type="radio" name="option" value="Option 1">Option 1</label>
<label><input type="radio" name="option" value="Option 2">Option 2</label>
The only significant difference is that, once one of them is selected, at least one of them has to be on (ie, you can't uncheck them again).
If you really feel the need to do it with check boxes, remind yourself that users with JavaScript disabled will be able to select all the options if they like. If you still feel the need to do it, then you'll need to give each checkbox group a unique class name. Then, handle the change event of each checkbox element and uncheck all the other elements matching the same class name as the clicked element.
I hope this one will work
HTML
A <input type="checkbox" class="alpha" value="A" /> |
B <input type="checkbox" class="alpha" value="B" /> |
C <input type="checkbox" class="alpha" value="C" />
<br />
1 <input type="checkbox" class="num" value="1" /> |
2 <input type="checkbox" class="num" value="2" /> |
3 <input type="checkbox" class="num" value="3" />
JavaScript
// include jQuery library
var enforeMutualExcludedCheckBox = function(group){
return function() {
var isChecked= $(this).prop("checked");
$(group).prop("checked", false);
$(this).prop("checked", isChecked);
}
};
$(".alpha").click(enforeMutualExcludedCheckBox(".alpha"));
$(".num").click(enforeMutualExcludedCheckBox(".num"));
well, radio button should be the one to be used in mutually excluded options, though I've encountered a scenario where the client preferred to have zero to one selected item, and the javaScript'ed checkbox works well.
Update
Looking at my answer, I realized it's redundant to refer to the css class twice. I updated my code to convert it into a jquery plugin, and created two solutions, depending on ones preference
Get all checkboxes whose check is mutually excluded
$.fn.mutuallyExcludedCheckBoxes = function(){
var $checkboxes = this; // refers to selected checkboxes
$checkboxes.click(function() {
var $this = $(this),
isChecked = $this.prop("checked");
$checkboxes.prop("checked", false);
$this.prop("checked", isChecked);
});
};
// more elegant, just invoke the plugin
$("[name=alpha]").mutuallyExcludedCheckBoxes();
$("[name=num]").mutuallyExcludedCheckBoxes();
HTML
A <input type="checkbox" name="alpha" value="A" /> |
B <input type="checkbox" name="alpha" value="B" /> |
C <input type="checkbox" name="alpha" value="C" />
<br />
1 <input type="checkbox" name="num" value="1" /> |
2 <input type="checkbox" name="num" value="2" /> |
3 <input type="checkbox" name="num" value="3" />
sample code
Group all mutually excluded checkboxes in a containing element
JavaScript
$.fn.mutuallyExcludedCheckBoxes = function(){
var $checkboxes = this.find("input[type=checkbox]");
$checkboxes.click(function() {
var $this = $(this),
isChecked = $this.prop("checked");
$checkboxes.prop("checked", false);
$this.prop("checked", isChecked);
});
};
// select the containing element, then trigger the plugin
// to set all checkboxes in the containing element mutually
// excluded
$(".alpha").mutuallyExcludedCheckBoxes();
$(".num").mutuallyExcludedCheckBoxes();
HTML
<div class="alpha">
A <input type="checkbox" value="A" /> |
B <input type="checkbox" value="B" /> |

Enjoy :-)

​JavaScript/jQuery
$(':checkbox.radiocheckbox').click(function() {
this.checked
&& $(this).siblings('input[name="' + this.name + '"]:checked.' + this.className)
.prop('checked', false);
});​
Mutually exclusive checkboxes are grouped by container+name+classname.
You can use different groups in same container and also mix exclusive with non-exclusive checkbox with same name.
JavaScript code is highly optimized. You can see a working example.
No matter where the check box is located on your page, you just need to specify the group and here you go!
<input type='checkbox' data-group='orderState'> pending
<input type='checkbox' data-group='orderState'> solved
<input type='checkbox' data-group='orderState'> timed out
<input type='checkbox' data-group='sex'> male
<input type='checkbox' data-group='sex'> female
<input type='checkbox'> Isolated
<script>
$(document).ready(function () {
$('input[type=checkbox]').click(function () {
var state = $(this)[0].checked,
g = $(this).data('group');
$(this).siblings()
.each(function () {
$(this)[0].checked = g==$(this).data('group')&&state ? false : $(this)[0].checked;
});
});
})</script>
I guess this is what you want.
Consider the HTML below:
<form action="">
My favourite colors are:<br />
<br />
<input type="checkbox" value="red" name="color" /> Red<br />
<input type="checkbox" value="yellow" name="color" /> Yellow<br />
<input type="checkbox" value="blue" name="color" /> Blue<br />
<input type="checkbox" value="orange" name="color1" /> Orange<br />
<input type="checkbox" value="green" name="color1" /> Green<br />
<input type="checkbox" value="purple" name="color1" /> Purple
</form>
Note that there's two names for color groups: red, yellow, blue and orage, green, purple
And this JavaScript noted below will work generically to all checkbox on the page.
jQuery("input[type=checkbox]").unbind("click");
jQuery("input[type=checkbox]").each(function(index, value) {
var checkbox = jQuery(value);
checkbox.bind("click", function () {
var check = checkbox.attr("checked");
jQuery("input[name=" + checkbox.attr('name') + "]").prop("checked", false);
checkbox.attr("checked", check);
});
});
Take a look at this LIVE example
