Javascript: Select all checkboxes by classname

Javascript: Select all checkboxes by classname - javascript

I'm having an issue with the following code which selects all checkboxes in the row based on the 'Select All' button clicked. The problem is I have to click each button twice if some checkboxes are already checked in order to change their state. I'd like to do this with just one click on each button no matter if checkboxes are selected or not. Is there a simple way to do this? Thank you!

checked = true;
function CheckUncheckAllAndExcludeDisabledByClass(theElement,theCheckBoxClass) {
var checks = document.querySelectorAll('.' + theCheckBoxClass);
for (var i = 0; i < checks.length; i++) {
var check = checks[i];
if (!check.disabled) {
check.checked = checked;
}
}
checked = !checked;
}

You can use this demo to check uncheck of checkbox on single click, click on below link and check demo and integrate in your system.
HTML CODE:
<div id="divCheckAll">
<input type="checkbox" name="checkall" id="checkall" onClick="check_uncheck_checkbox(this.checked);" />Check All</div>
<div id="divCheckboxList">
<div class="divCheckboxItem"><input type="checkbox" name="language" id="language1" value="English" />English</div>
<div class="divCheckboxItem"><input type="checkbox" name="language" id="language2" value="French" />French</div>
<div class="divCheckboxItem"><input type="checkbox" name="language" id="language3" value="German" />German</div>
<div class="divCheckboxItem"><input type="checkbox" name="language" id="language4" value="Latin" />Latin</div>
</div>
Jquery Code
function check_uncheck_checkbox(isChecked) {
if(isChecked) {
$('input[name="language"]').each(function() {
this.checked = true;
});
} else {
$('input[name="language"]').each(function() {
this.checked = false;
});
}
}

You need to store separate state for each checkbox type
checked = {};
function CheckUncheckAllAndExcludeDisabledByClass(theElement, theCheckBoxClass) {
var checks = document.querySelectorAll('.' + theCheckBoxClass);
var ckd = checked[theCheckBoxClass] === false ? false : true;
for (var i = 0; i < checks.length; i++) {
var check = checks[i];
if (!check.disabled) {
check.checked = ckd;
}
}
checked[theCheckBoxClass] = !ckd;
}
<form name="editview">
<input type="checkbox" id="edit_1" name="check1" class="edit">
<input type="checkbox" id="edit_2" name="check2" class="edit" disabled="disabled" checked="checked">
<input type="checkbox" id="edit_3" name="check3" class="edit" disabled="disabled">
<input type="checkbox" id="edit_4" name="check4" class="edit">
<input type="button" class="button" value="Select All" onclick="CheckUncheckAllAndExcludeDisabledByClass(this,'edit')" title="Select all: items.">
<input type="checkbox" id="view_5" name="check5" class="view">
<input type="checkbox" id="view_6" name="check6" class="view" disabled="disabled" checked="checked">
<input type="checkbox" id="view_7" name="check7" class="view" disabled="disabled">
<input type="checkbox" id="view_8" name="check8" class="view">
<input type="button" class="button" value="Select All" onclick="CheckUncheckAllAndExcludeDisabledByClass(this,'view')" title="Select all: items.">
</form>
But if you have jQuery then
$('.select-all').click(function() {
var $this = $(this),
checked = !$this.data('checked');
$('.' + $this.data('class')).not(':disabled').prop('checked', checked);
$this.data('checked', checked)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<form name="editview">
<input type="checkbox" id="edit_1" name="check1" class="edit">
<input type="checkbox" id="edit_2" name="check2" class="edit" disabled="disabled" checked="checked">
<input type="checkbox" id="edit_3" name="check3" class="edit" disabled="disabled">
<input type="checkbox" id="edit_4" name="check4" class="edit">
<input type="button" class="button select-all" value="Select All" title="Select all: items." data-class="edit">
<input type="checkbox" id="view_5" name="check5" class="view">
<input type="checkbox" id="view_6" name="check6" class="view" disabled="disabled" checked="checked">
<input type="checkbox" id="view_7" name="check7" class="view" disabled="disabled">
<input type="checkbox" id="view_8" name="check8" class="view">
<input type="button" class="button select-all" value="Select All" title="Select all: items." data-class="view">
</form>

You can do it like this :
HTML :
<div id="test">
<input type="checkbox" id="check1" name="check1" class="check">
<input type="checkbox" id="check01" name="check01" class="check" disabled="disabled" checked>
<input type="checkbox" id="check2" name="check2" class="check" disabled="disabled">
<input type="checkbox" id="check3" name="check3" class="check">
<input type="checkbox" id="check4" name="check4" class="check">
<input type="checkbox" id="check50" name="check50" class="check">
<input type="checkbox" id="check6" name="check6" class="check">
</div>
<input type="button" id="uncheckAll" value="select all">
JS :
$('#uncheckAll').click(function(){
var checks = $('input[class="check"]');
for(var i =0; i< checks.length;i++){
var check = checks[i];
if(!check.disabled){
if (check.checked) {
check.checked = false;
}
}
}
for(var i =0; i< checks.length;i++){
var check = checks[i];
if(!check.disabled){
if (!check.checked) {
check.checked = true;
}
}
}
});
Here is the working Fiddle
Do let me know if it is according to your requirement.
Happy Coding.

Try adjusting checked variable to utilize Array.prototype.filter to select elements not disabled , Array.prototype.every to toggle element checked attribute
function CheckUncheckAllAndExcludeDisabledByClass(theElement, theCheckBoxClass) {
var checks = document.querySelectorAll('.' + theCheckBoxClass);
var checked = Array.prototype.filter.call(checks, function(el) {
return !el.disabled
}).every(function(el) {
return el.checked
});
for (var i = 0; i < checks.length; i++) {
var check = checks[i];
if (!check.disabled) {
check.checked = !checked ? true : false;
}
}
}
<form name="editview">
<input type="checkbox" id="edit_1" name="check1" class="edit">
<input type="checkbox" id="edit_2" name="check2" class="edit" disabled="disabled" checked="checked">
<input type="checkbox" id="edit_3" name="check3" class="edit" disabled="disabled">
<input type="checkbox" id="edit_4" name="check4" class="edit">
<input type="button" class="button" value="Select All" onclick="CheckUncheckAllAndExcludeDisabledByClass(this,'edit')" title="Select all: items.">
<input type="checkbox" id="view_5" name="check5" class="view">
<input type="checkbox" id="view_6" name="check6" class="view" disabled="disabled" checked="checked">
<input type="checkbox" id="view_7" name="check7" class="view" disabled="disabled">
<input type="checkbox" id="view_8" name="check8" class="view">
<input type="button" class="button" value="Select All" onclick="CheckUncheckAllAndExcludeDisabledByClass(this,'view')" title="Select all: items.">
</form>

Problem is you are using same flag for multiple class names:
Plain Js solution:
var state = {};
var toggle = function(clas) {
var chk = state[clas] = !state[clas];//flips the state (true/false)
var chks = document.getElementsByClassName(clas);
var l = chks.length;
while (l--)
if (!chks[l].disabled)
chks[l].checked = chk;
};
<form name="editview">
<input type="checkbox" id="edit_1" name="check1" class="edit">
<input type="checkbox" id="edit_2" name="check2" class="edit" disabled="disabled" checked="checked">
<input type="checkbox" id="edit_3" name="check3" class="edit" disabled="disabled">
<input type="checkbox" id="edit_4" name="check4" class="edit">
<input type="button" class="button" value="Select All" onclick="toggle('edit')" title="Select all: items.">
<input type="checkbox" id="view_5" name="check5" class="view">
<input type="checkbox" id="view_6" name="check6" class="view" disabled="disabled" checked="checked">
<input type="checkbox" id="view_7" name="check7" class="view" disabled="disabled">
<input type="checkbox" id="view_8" name="check8" class="view">
<input type="button" class="button" value="Select All" onclick="toggle('view')" title="Select all: items.">
</form>

How to dynamic check whether checkbox is in another table Javascript/PHP?

I have two tables, table 1 with the fields of webID, project, web, and I use below PHP code(ThinkPHP framework) to get project list:
$project = M('WebProjectList')->where(array('web' => self::$web))->getField('project', true);
table 2 with the fields of userID, issue, web, project and I use below PHP code to get issue list:
$where['web'] = self::$web;
$where['project'] = array('in', $project);
$issue = M('UserIssue')->where($where)->group('issue')->getField('issue',true);
Below code in .js is the multiple-choice/checkbox of both projects and issues that let user choose, when user choose an issue which does not belong to that project, how to reminder user to check again before submitting?
$('.project2').each(function (index) {
var project = result[index].project;
for (var i in project) {
var item = $('input[value="' + project[i] + '"]');
$(this).find(item).attr('checked', 'checked');
}
});
$('.issue2').each(function (index) {
var issue = result[index].issue;
for (var i in issue) {
var item1 = $('input[value="' + issue[i] + '"]');
$(this).find(item1).attr('checked', 'checked');
}
});
And html code as below:
<th>Project</th>
<td>
<div style="width: 800px" class="project2">
<foreach name="projectlist" item="item">
<label style="display: inline-block">
<input type="checkbox" name="project" style="height: 18px;width: 18px" value="{$item}"/>
{$item}
</label>
</foreach>
<input type="checkbox" name="project" style="display: none" value="all" checked>
</div>
</td>
</tr>
<tr>
<th>Issue</th>
<td>
<div style="width: 800px" class="issue2">
<foreach name="issueList" item="item1">
<label style="display: inline-block">
<input type="checkbox" name="issue" style="height: 18px;width: 18px" value="{$item1}"/>
{$item1}
</label>
</foreach>
<input type="checkbox" name="issue" style="display: none" value="all" checked>
</div>
</td>
</tr>
and the actual html from inspect as below:
$('.project2').each(function(index) {
var project = result[index].project;
for (var i in project) {
var item = $('input[value="' + project[i] + '"]');
$(this).find(item).attr('checked', 'checked');
}
});
$('.issue2').each(function(index) {
var issue = result[index].issue;
for (var i in issue) {
var item1 = $('input[value="' + issue[i] + '"]');
$(this).find(item1).attr('checked', 'checked');
}
});
label {
display: inline-block;
}
input[type=checkbox] {
height: 18px;
width: 18px;

Pass selected checkboxes from popup window to text input on a dynamic table

I have a dynamic table the user add's rows to by clicking the Add row button. In the row i have a button 'Select Scope' that opens a new window full of checkbox's I'm trying to get all of the selected checkbox's values to post to a text input in the dynamic table from the parent page. Dynamic Table PicSelect Scope Pic I know that this is possible just using javascript and I feel like I am on the right track from everything that I have read. For whatever reason though it's not passing the checkbox values back to the text input.
Parent Page Code

Toggle multiple Checkbox at once

I have these checkboxs:
'<input type="checkbox" name="checkBox1" value="checked" class= "toggleable">';
'<input type="checkbox" name="checkBox2" value="checked" class= "toggleable">';
'<input type="checkbox" name="checkBox3" value="checked" class= "toggleable">';
Which I can check or uncheck by clinking on them. Now I am trying to add one more checkbox, which will check or uncheck all previous checkbox at once when clicking.
'<input type="checkbox" name="check_uncheck_all" value="false" id="id_check_uncheck_all">'
What is the JS code to execute when clicking the checkbox to check or uncheck all checkbox "toggleable" at once?

Here's an example on how to make this work in pure JavaScript.
var checkAll = document.getElementById("id_check_uncheck_all");
checkAll.addEventListener("change", function() {
var checked = this.checked;
var otherCheckboxes = document.querySelectorAll(".toggleable");
[].forEach.call(otherCheckboxes, function(item) {
item.checked = checked;
});
});
<label for="id_check_uncheck_all">Select All</label>
<input type="checkbox" name="check_uncheck_all" value="false" id="id_check_uncheck_all">
<br/>
<input type="checkbox" name="checkBox1" value="checked" class= "toggleable">
<input type="checkbox" name="checkBox2" value="checked" class= "toggleable">
<input type="checkbox" name="checkBox3" value="checked" class= "toggleable">

try it
$(document).ready(function() {
$(".toggleable").click(function() {
var checkboxes = $(".toggleable");
if($(this).prop("checked")) checkboxes.prop("checked",true);
else checkboxes.prop("checked",false);
})
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" name="checkBox1" class= "toggleable">
<input type="checkbox" name="checkBox2" class= "toggleable">
<input type="checkbox" name="checkBox3" class= "toggleable">

Just verify through JS that if particular checkbox checked. It has to check all of them.
JS Demo Below: UPDATE
Just added id to your inputs.
function checkAll(x) {
if(x.checked == true){
document.getElementById('c1').checked = true;
document.getElementById('c2').checked = true;
document.getElementById('c3').checked = true;
}else{
document.getElementById('c1').checked = false;
document.getElementById('c2').checked = false;
document.getElementById('c3').checked = false;
}
}
Multiple Check Box Below:
<br>
<input type="checkbox" name="checkBox1" value="checked" class="toggleable" id="c1">
<input type="checkbox" name="checkBox2" value="checked" class="toggleable" id="c2">
<input type="checkbox" name="checkBox3" value="checked" class="toggleable" id="c3">
</br>
Check below to Check them all:
</br>
<input type="checkbox" name="check_uncheck_all" onchange='checkAll(this);' value="false" id="id_check_uncheck_all">
JQuery Demo below:
$('#checkAll').click(function () {
$('input:checkbox').prop('checked', this.checked);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<input type="checkbox" id="checkAll" > Check All
</br>
<input type="checkbox" id="checkItem"> Item 1
<input type="checkbox" id="checkItem"> Item 2
<input type="checkbox" id="checkItem"> Item3

addClassRules() to multiple fields but only allow 1 at a minimum

So I have 10 checkbox fields, more then 1 can be selected, but at least 1 has to be selected at a minimum.
I had it working use the name="" attribute but that was not the case anymore as the name has to be unique to integrate with our CRM.
So I added the rule to use the class instead using addClassRule() and I added my own method to use a custom message for required.
But the result is they are all required. regardless if 1 or more is selected?
Here is my jQuery which is working but it requires all 10 checkbox's to be checked.
$.validator.addMethod("checkboxRequired", $.validator.methods.required, "Please select at least 1 of the values");
jQuery.validator.addClassRules('checkbox-validate', {
checkboxRequired: true
});
HTML code:
<div id="id_1" class="form-input">
<label for="test1"><input class="checkbox-validate" type="checkbox" id="test1" name="test1" value="1">1</label>
<label for="test2"><input class="checkbox-validate" type="checkbox" id="test2" name="test2" value="2">2</label>
<label for="test3"><input class="checkbox-validate" type="checkbox" id="test3" name="test3" value="3">3</label>
<label for="test4"><input class="checkbox-validate" type="checkbox" id="test4" name="test4" value="4">4</label>
<label for="test5"><input class="checkbox-validate" type="checkbox" id="test5" name="test5" value="5">5</label>
<label for="test6"><input class="checkbox-validate" type="checkbox" id="test6" name="test6" value="6">6</label>
<label for="test7"><input class="checkbox-validate" type="checkbox" id="test7" name="test7" value="7">7</label>
<label for="test8"><input class="checkbox-validate" type="checkbox" id="test8" name="test8" value="8">8</label>
<label for="test9"><input class="checkbox-validate" type="checkbox" id="test9" name="test9" value="9">9</label>
<label for="test10"><input class="checkbox-validate" type="checkbox" id="test10" name="test10" value="10">10</label>
</div>

Try require_from_group-method rule
jQuery(function($) {
jQuery.validator.addClassRules('checkbox-validate', {
require_from_group: [1, ".checkbox-validate"]
});
var validator = $('#myform').validate({
rules: {},
messages: {},
errorPlacement: function(error, element) {
if (element.hasClass('checkbox-validate')) {
element.closest('.form-input').find('.error-holder').html(error)
} else {
error.insertAfter(element);
}
}
});
});

You need to make your name attribute all be the same value. Then you can check how many are checked like so:
var count = $('input[name=test]:checked').size();

Checkbox(javascript) selection, first item showing undefined?

I am trying to select and return some items(checkbox). Everything is okay, but the first item is always showing UNDEFINED. can't fix this problem!
My code is as below
function checkList () {
var checked;
var i;
for( i = 0; i < document.form1.length; i++) {
var element = document.form1[i]
if (element.type == "checkbox"){
if (element.checked == true){
checked = checked + element.value + "<br/>";
}
}
}
document.getElementById('checked').innerHTML = checked;
}
<form name="form1">
<input type="checkbox" name="checkbox1" id="checkbox1" value="Pen" />
<label value="Earned" for="checkbox1">Pen</label>
<br />
<input type="checkbox" name="checkbox2" id="checkbox2" value="Book" />
<label value="Earned" for="checkbox2" >Book</label>
<br/>

<label value="Earned" for="checkbox3">Sharpner</label>
<br/>
<input type="checkbox" id="checkbox4" name="checkbox1" value="Pencil" />
<label value="Earned" for="checkbox4">Pencil</label>
<br/> <br/>
<input type="button" id="done" value="Done" onclick="checkList()" />
<br/><br/>
</form>
<p >You are taking:</p>
<span id="checked"></span>

Try to Change
<form name="form1">

<label value="Earned" for="checkbox1">Pen</label>
<br />
<input type="checkbox" name="checkbox2" id="checkbox2" value="Book" />

<br/><br/>
</form>
<p >You are taking:</p>
<span id="checked"></span>
You have multiple duplications within the code such as (for="")
Let me know, Thanks

Change
var checked; // like this, checked is undefined
to
var checked = ""; // now it's simply empty
here's a fiddle
http://jsfiddle.net/sq9938b0/

The issue is that you initialize checked variable as undefined. When you append the string to undefined it is converted to string "undefined", hence it appearing at the beginning.
Just initialize it as an empty string: var checked = "";
function checkList () {
var checked = "";
var i;
for( i = 0; i < document.form1.length; i++) {
var element = document.form1[i]
if (element.type == "checkbox"){
if (element.checked == true){
checked = checked + element.value + "<br/>";
}
}
}
document.getElementById('checked').innerHTML = checked;
}
<form name="form1">
<input type="checkbox" name="checkbox1" id="checkbox1" value="Pen" />
<label value="Earned" for="checkbox1">Pen</label>
<br />
<input type="checkbox" name="checkbox2" id="checkbox2" value="Book" />
<label value="Earned" for="checkbox2" for="checkbox">Book</label>
<br/>
<input type="checkbox" name="checkbox1" id="checkbox3" value="Sharpner" />
<label value="Earned" for="checkbox3" for="checkbox" for="checkbox">Sharpner</label>
<br/>
<input type="checkbox" id="checkbox4" name="checkbox1" value="Pencil" />
<label value="Earned" for="checkbox4">Pencil</label>
<br/> <br/>
<input type="button" id="done" value="Done" onclick="checkList()" />
<br/><br/>
</form>
<p >You are taking:</p>
<span id="checked"></span>

Take a look of the following step
checked = checked + element.value + "";
In the first loop you have not defined checked. So first time it is
checked = undefined + pen
Intialize
var checked = ''
