I am writing this code, but unable to get anything. Any help is appreciated.
<!DOCTYPE HTML>

<head>
<script>
function computeMarks() {
var inputElems = document.form1.getElementsByTagName("input");
var count = 0;
for (var i =0; i<=inputElems.length; i++) {
if(inputElems[i].type === "checkbox" && inputElems[i].checked) {
count++;
}
}
alert(count);
}
</script>
</head>
<body>
<form name="form1" id="form1">
<input type="checkbox" name="quiz" value=1 /> Hi
<input type="checkbox" name="quiz" value=1 /> Bye
<input type="checkbox" name="quiz" value=1 /> See ya
<input type="button" onClick="computeMarks()" value="Compute Marks"/>
</form>
</body>
</html>
I have tried to do getElementByName("quiz") but the same thing is happening.
Change i<=inputElems.length to i < inputElems.length. Array indexes run from 0 to length-1. You're getting an error when i is inputElements.length (when your scripts don't work, isn't the Javascript console the first place you look for help?).

Well what you need to do is just remove = sign from <= in your code.
<!DOCTYPE HTML>
<html>
<head>
<script>
function computeMarks() {
var inputElems = document.form1.getElementsByTagName("input");
var count = 0;
for (var i =0; i<inputElems.length; i++) {
if(inputElems[i].type === "checkbox" && inputElems[i].checked) {
count++;
}
}
alert(count);
}
</script>
</head>
<body>
<form name="form1" id="form1">
<input type="checkbox" name="quiz" value=1 /> Hi
<input type="checkbox" name="quiz" value=1 /> Bye
<input type="checkbox" name="quiz" value=1 /> See ya
<input type="button" onClick="computeMarks()" value="Compute Marks"/>
</form>
</body>
</html>
I recommand the JQuery to do this, it's way easier. Here is an example if you use JQuery in your code instead of plain javascript:
<!DOCTYPE HTML>
<html>
<head>
<script src="http://code.jquery.com/jquery-1.11.1.min.js"></script>
<script>
function computeMarks() {
var counter = 0;
$('input[type="checkbox"]').each(function(){
if($(this).prop('checked'))
{
counter++;
}
});
alert(counter);
}
</script>
</head>
<body>
<form name="form1" id="form1">
<input type="checkbox" name="quiz" value=1 /> Hi
<input type="checkbox" name="quiz" value=1 /> Bye
<input type="checkbox" name="quiz" value=1 /> See ya
<input type="button" onClick="computeMarks()" value="Compute Marks"/>
</form>
</body>
</html>
You can get the reference of the form and loop through it's elements to see if they are checked or not, simply replace your function with this and it should work:
function computeMarks() {
var checked = 0;
var form = document.getElementById("form1");
var index, element;
for (index = 0; index < form.elements.length; ++index) {
element = form.elements[index];
// You may want to check `element.name` here as well
if (element.type.toUpperCase() == "CHECKBOX" && element.checked)
++checked;
}
alert(checked);
}
See the DEMO here
I would recommend you query the elements, and add the event in JavaScript, for example:
var form = document.form1
var button = form.querySelector('[type="button"]')
var checkboxes = form.querySelectorAll('[type="checkbox"]')
var computeMarks = function(els) {
return []
.map.call(els, function(x){return +x.checked})
.reduce(function(x, y){return x + y})
}
button.addEventListener('click', function() {
alert(computeMarks(checkboxes))
})

I know how to check and uncheck particular checkbox with ID and CLASS.
But I want to randomly select 10 checkbox using Jquery.
I will have 100,40 or XX number of checkbox everytime. (HTML Checkbox)
It might be 100 checkbox or 50 checkbox or something else. It will be different everytime.
I want to check 10 checkboxes randomly when a button is pressed.
User can manually select those 10 checkboxes. Or they can just press the random button.
I am using Jquery.
$(':checkbox:checked').length;
But i want to find the length of all the checkboxes and i want to check 10 random checkbox.
Are you looking for something like this?

I have an HTML page with multiple checkboxes.
I need one more checkbox by the name "select all". When I select this checkbox all checkboxes in the HTML page must be selected. How can I do this?
<script language="JavaScript">
function toggle(source) {
checkboxes = document.getElementsByName('foo');
for(var checkbox in checkboxes)
checkbox.checked = source.checked;
}
</script>
<input type="checkbox" onClick="toggle(this)" /> Toggle All<br/>
<input type="checkbox" name="foo" value="bar1"> Bar 1<br/>
<input type="checkbox" name="foo" value="bar2"> Bar 2<br/>
<input type="checkbox" name="foo" value="bar3"> Bar 3<br/>
<input type="checkbox" name="foo" value="bar4"> Bar 4<br/>
UPDATE:
The for each...in construct doesn't seem to work, at least in this case, in Safari 5 or Chrome 5. This code should work in all browsers:
function toggle(source) {
checkboxes = document.getElementsByName('foo');
for(var i=0, n=checkboxes.length;i<n;i++) {
checkboxes[i].checked = source.checked;
}
}
Using jQuery:
// Listen for click on toggle checkbox
$('#select-all').click(function(event) {
if(this.checked) {
// Iterate each checkbox
$(':checkbox').each(function() {
this.checked = true;
});
} else {
$(':checkbox').each(function() {
this.checked = false;
});
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" name="checkbox-1" id="checkbox-1" />
<input type="checkbox" name="checkbox-2" id="checkbox-2" />
<input type="checkbox" name="checkbox-3" id="checkbox-3" />
<!-- select all boxes -->
<input type="checkbox" name="select-all" id="select-all" />
I'm not sure anyone hasn't answered in this way (using jQuery):
$( '#container .toggle-button' ).click( function () {
$( '#container input[type="checkbox"]' ).prop('checked', this.checked)
})
It's clean, has no loops or if/else clauses and works as a charm.
I'm surprised no one mentioned document.querySelectorAll(). Pure JavaScript solution, works in IE9+.
function toggle(source) {
var checkboxes = document.querySelectorAll('input[type="checkbox"]');
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i] != source)
checkboxes[i].checked = source.checked;
}
}
<input type="checkbox" onclick="toggle(this);" />Check all?<br />
<input type="checkbox" />Bar 1<br />
<input type="checkbox" />Bar 2<br />
<input type="checkbox" />Bar 3<br />
<input type="checkbox" />Bar 4<br />
here's a different way less code
$(function () {
$('#select-all').click(function (event) {
var selected = this.checked;
// Iterate each checkbox
$(':checkbox').each(function () { this.checked = selected; });
});
});

When you call document.getElementsByName("name"), you will get a Object. Use .item(index) to traverse all items of a Object
HTML:
<input type="checkbox" onclick="for(c in document.getElementsByName('rfile')) document.getElementsByName('rfile').item(c).checked = this.checked">
<input type="checkbox" name="rfile" value="/cgi-bin/">
<input type="checkbox" name="rfile" value="/includes/">
<input type="checkbox" name="rfile" value="/misc/">
<input type="checkbox" name="rfile" value="/modules/">
<input type="checkbox" name="rfile" value="/profiles/">
<input type="checkbox" name="rfile" value="/scripts/">
<input type="checkbox" name="rfile" value="/sites/">
<input type="checkbox" name="rfile" value="/stats/">
<input type="checkbox" name="rfile" value="/themes/">
Slightly changed version which checks and unchecks respectfully
$('#select-all').click(function(event) {
var $that = $(this);
$(':checkbox').each(function() {
this.checked = $that.is(':checked');
});
});
My simple solution allows to selectively select/deselect all checkboxes in a given portion of the form, while using different names for each checkbox, so that they can be easily recognized after the form is POSTed.
Javascript:
function setAllCheckboxes(divId, sourceCheckbox) {
divElement = document.getElementById(divId);
inputElements = divElement.getElementsByTagName('input');
for (i = 0; i < inputElements.length; i++) {
if (inputElements[i].type != 'checkbox')
continue;
inputElements[i].checked = sourceCheckbox.checked;
}
}
HTML example:
<p><input onClick="setAllCheckboxes('actors', this);" type="checkbox" />All of them</p>
<div id="actors">
<p><input type="checkbox" name="kevin" />Spacey, Kevin</p>
<p><input type="checkbox" name="colin" />Firth, Colin</p>
<p><input type="checkbox" name="scarlett" />Johansson, Scarlett</p>
</div>
I hope you like it!

Try this simple JQuery:
$('#select-all').click(function(event) {
if (this.checked) {
$(':checkbox').prop('checked', true);
} else {
$(':checkbox').prop('checked', false);
}
});
JavaScript is your best bet. The link below gives an example using buttons to de/select all. You could try to adapt it to use a check box, just use you 'select all' check box' onClick attribute.
Javascript Function to Check or Uncheck all Checkboxes
This page has a simpler example
http://www.htmlcodetutorial.com/forms/_INPUT_onClick.html
This sample works with native JavaScript where the checkbox variable name varies, i.e. not all "foo."
<!DOCTYPE html>
<html>
<body>
<p>Toggling checkboxes</p>
<script>
function getcheckboxes() {
var node_list = document.getElementsByTagName('input');
var checkboxes = [];
for (var i = 0; i < node_list.length; i++)
{
var node = node_list[i];
if (node.getAttribute('type') == 'checkbox')
{
checkboxes.push(node);
}
}
return checkboxes;
}
function toggle(source) {
checkboxes = getcheckboxes();
for (var i = 0 n = checkboxes.length; i < n; i++)
{
checkboxes[i].checked = source.checked;
}
}
</script>
<input type="checkbox" name="foo1" value="bar1"> Bar 1<br/>
<input type="checkbox" name="foo2" value="bar2"> Bar 2<br/>
<input type="checkbox" name="foo3" value="bar3"> Bar 3<br/>
<input type="checkbox" name="foo4" value="bar4"> Bar 4<br/>
<input type="checkbox" onClick="toggle(this)" /> Toggle All<br/>
</body>
</html>
It's rather simple:
const selectAllCheckboxes = () => {
const checkboxes = document.querySelectorAll('input[type=checkbox]');
checkboxes.forEach((cb) => { cb.checked = true; });
}
If adopting the top answer for jQuery, remember that the object passed to the click function is an EventHandler, not the original checkbox object. Therefore code should be modified as follows.
HTML
<input type="checkbox" name="selectThemAll"/> Toggle All<br/>
<input type="checkbox" name="foo" value="bar1"> Bar 1<br/>
<input type="checkbox" name="foo" value="bar2"> Bar 2<br/>
<input type="checkbox" name="foo" value="bar3"> Bar 3<br/>
<input type="checkbox" name="foo" value="bar4"> Bar 4<br/>
Javascript
$(function() {
jQuery("[name=selectThemAll]").click(function(source) {
checkboxes = jQuery("[name=foo]");
for(var i in checkboxes){
checkboxes[i].checked = source.target.checked;
}
});
})
<asp:CheckBox ID="CheckBox1" runat="server" Text="Select All" onclick="checkAll(this);" />
<br />
<asp:CheckBoxList ID="CheckBoxList1" runat="server">
<asp:ListItem Value="Item 1">Item 1</asp:ListItem>
<asp:ListItem Value="Item 2">Item 2</asp:ListItem>
<asp:ListItem Value="Item 3">Item 3</asp:ListItem>
<asp:ListItem Value="Item 4">Item 4</asp:ListItem>
<asp:ListItem Value="Item 5">Item 5</asp:ListItem>
<asp:ListItem Value="Item 6">Item 6</asp:ListItem>
</asp:CheckBoxList>
<script type="text/javascript">
function checkAll(obj1) {
var checkboxCollection = document.getElementById('<%=CheckBoxList1.ClientID %>').getElementsByTagName('input');
for (var i = 0; i < checkboxCollection.length; i++) {
if (checkboxCollection[i].type.toString().toLowerCase() == "checkbox") {
checkboxCollection[i].checked = obj1.checked;
}
}
}
</script>
that should do the job done:
$(':checkbox').each(function() {
this.checked = true;
});
You may have different sets of checkboxes on the same form. Here is a solution that selects/unselects checkboxes by class name, using vanilla javascript function document.getElementsByClassName
The Select All button
<input type='checkbox' id='select_all_invoices' onclick="selectAll()"> Select All
Some of the checkboxes to select
<input type='checkbox' class='check_invoice' id='check_123' name='check_123' value='321' />
<input type='checkbox' class='check_invoice' id='check_456' name='check_456' value='852' />
The javascript
function selectAll() {
var blnChecked = document.getElementById("select_all_invoices").checked;
var check_invoices = document.getElementsByClassName("check_invoice");
var intLength = check_invoices.length;
for(var i = 0; i < intLength; i++) {
var check_invoice = check_invoices[i];
check_invoice.checked = blnChecked;
}
}
This is what this will do, for instance if you have 5 checkboxes, and you click check all,it check all, now if you uncheck all the checkbox probably by clicking each 5 checkboxs, by the time you uncheck the last checkbox, the select all checkbox also gets unchecked
$("#select-all").change(function(){
$(".allcheckbox").prop("checked", $(this).prop("checked"))
})
$(".allcheckbox").change(function(){
if($(this).prop("checked") == false){
$("#select-all").prop("checked", false)
}
if($(".allcheckbox:checked").length == $(".allcheckbox").length){
$("#select-all").prop("checked", true)
}
})
As I cannot comment, here as answer:
I would write Can Berk Güder's solution in a more general way,
so you may reuse the function for other checkboxes
<script language="JavaScript">
function toggleCheckboxes(source, cbName) {
checkboxes = document.getElementsByName(cbName);
for (var i = 0, n = checkboxes.length; i < n; i++) {
checkboxes[i].checked = source.checked;
}
}
</script>
<input type="checkbox" onClick="toggleCheckboxes(this,\'foo\')" /> Toggle All<br/>
<input type="checkbox" name="foo" value="bar1"> Bar 1<br/>
<input type="checkbox" name="foo" value="bar2"> Bar 2<br/>
<input type="checkbox" name="foo" value="bar3"> Bar 3<br/>
<input type="checkbox" name="foo" value="bar4"> Bar 4<br/>
<input type="checkbox" name="foo" value="bar5"> Bar 5<br/>
$(document).ready(function() {
$(document).on(' change', 'input[name="check_all"]', function() {
$('.cb').prop("checked", this.checked);
});
});
Using jQuery and knockout:
With this binding main checkbox stays in sync with underliying checkboxes, it will be unchecked unless all checkboxes checked.
ko.bindingHandlers.allChecked = {
init: function (element, valueAccessor) {
var selector = valueAccessor();
function getChecked () {
element.checked = $(selector).toArray().every(function (checkbox) {
return checkbox.checked;
});
}
function setChecked (value) {
$(selector).toArray().forEach(function (checkbox) {
if (checkbox.checked !== value) {
checkbox.click();
}
});
}
ko.utils.registerEventHandler(element, 'click', function (event) {
setChecked(event.target.checked);
});
$(window.document).on('change', selector, getChecked);
ko.utils.domNodeDisposal.addDisposeCallback(element, () => {
$(window.document).off('change', selector, getChecked);
});
getChecked();
}
};
in html:
<input id="check-all-values" type="checkbox" data-bind="allChecked: '.checkValue'"/>
<input id="check-1" type="checkbox" class="checkValue"/>
<input id="check-2" type="checkbox" class="checkValue"/>
to make it in short-hand version by using jQuery
The select all checkbox
<input type="checkbox" id="chkSelectAll">
The children checkbox
<input type="checkbox" class="chkDel">
<input type="checkbox" class="chkDel">
<input type="checkbox" class="chkDel">
jQuery
$("#chkSelectAll").on('click', function(){
this.checked ? $(".chkDel").prop("checked",true) : $(".chkDel").prop("checked",false);
})
Below methods are very Easy to understand and you can implement existing forms in minutes
With Jquery,
$(document).ready(function() {
$('#check-all').click(function(){
$("input:checkbox").attr('checked', true);
});
$('#uncheck-all').click(function(){
$("input:checkbox").attr('checked', false);
});
});
in HTML form put below buttons
<a id="check-all" href="javascript:void(0);">check all</a>
<a id="uncheck-all" href="javascript:void(0);">uncheck all</a>
With just using javascript,
<script type="text/javascript">
function checkAll(formname, checktoggle)
{
var checkboxes = new Array();
checkboxes = document[formname].getElementsByTagName('input');
for (var i=0; i<checkboxes.length; i++) {
if (checkboxes[i].type == 'checkbox') {
checkboxes[i].checked = checktoggle;
}
}
}
</script>
in HTML form put below buttons
<button onclick="javascript:checkAll('form3', true);" href="javascript:void();">check all</button>
<button onclick="javascript:checkAll('form3', false);" href="javascript:void();">uncheck all</button>
Here is a backbone.js implementation:
events: {
"click #toggleChecked" : "toggleChecked"
},
toggleChecked: function(event) {
var checkboxes = document.getElementsByName('options');
for(var i=0; i<checkboxes.length; i++) {
checkboxes[i].checked = event.currentTarget.checked;
}
},
html
<input class='all' type='checkbox'> All
<input class='item' type='checkbox' value='1'> 1
<input class='item' type='checkbox' value='2'> 2
<input class='item' type='checkbox' value='3'> 3
javascript
$(':checkbox.all').change(function(){
$(':checkbox.item').prop('checked', this.checked);
});
1: Add the onchange event Handler
<th><INPUT type="checkbox" onchange="checkAll(this)" name="chk[]" /> </th>
2: Modify the code to handle checked/unchecked
function checkAll(ele) {
var checkboxes = document.getElementsByTagName('input');
if (ele.checked) {
for (var i = 0; i < checkboxes.length; i++) {
if (checkboxes[i].type == 'checkbox') {
checkboxes[i].checked = true;
}
}
} else {
for (var i = 0; i < checkboxes.length; i++) {
console.log(i)
if (checkboxes[i].type == 'checkbox') {
checkboxes[i].checked = false;
}
}
}
}
You can Use This code.
var checkbox = document.getElementById("dlCheckAll4Delete");
checkbox.addEventListener("click", function (event) {
let checkboxes = document.querySelectorAll(".dlMultiDelete");
checkboxes.forEach(function (ele) {
ele.checked = !!checkbox.checked;
});
});
You can use this simple code
$('.checkall').click(function(){
var checked = $(this).prop('checked');
$('.checkme').prop('checked', checked);
});
Maybe a bit late, but when dealing with a check all checkbox, I believe you should also handle the scenario for when you have the check all checkbox checked, and then unchecking one of the checkboxes below.
In that case it should automatically uncheck the check all checkbox.
Also when manually checking all the checkboxes, you should end up with the check all checkbox being automatically checked.
You need two event handlers, one for the check all box, and one for when clicking any of the single boxes below.
// HANDLES THE INDIVIDUAL CHECKBOX CLICKS
function client_onclick() {
var selectAllChecked = $("#chk-clients-all").prop("checked");
// IF CHECK ALL IS CHECKED, AND YOU'RE UNCHECKING AN INDIVIDUAL BOX, JUST UNCHECK THE CHECK ALL CHECKBOX.
if (selectAllChecked && $(this).prop("checked") == false) {
$("#chk-clients-all").prop("checked", false);
} else { // OTHERWISE WE NEED TO LOOP THROUGH INDIVIDUAL CHECKBOXES AND SEE IF THEY ARE ALL CHECKED, THEN CHECK THE SELECT ALL CHECKBOX ACCORDINGLY.
var allChecked = true;
$(".client").each(function () {
allChecked = $(this).prop("checked");
if (!allChecked) {
return false;
}
});
$("#chk-clients-all").prop("checked", allChecked);
}
}
// HANDLES THE TOP CHECK ALL CHECKBOX
function client_all_onclick() {
$(".client").prop("checked", $(this).prop("checked"));
}
