JQuery - Allow Specific 2 Checkboxes to be Selected - javascript

I only want 1 checkbox to be selected - UNLESS its checkbox 3 AND 4 - then I want to allow these 2 checkboxes to be selected. This is the only time I want 2 checkboxes allowed.
I have a working example of only allowing 1 checkbox. see the jsfiddle...
https://jsfiddle.net/rbla/s1setkfe/3/
I need to allow #3 and #4 to be selected
$(function() {
$('#submit').click(function() {
checked = $("input[type=checkbox]:checked").length;
if (!checked) {
alert("You must check at least one reason.");
return false;
}
});
});
// No more than 1 checkbox allowed
var limit = 1;
$('input.sing-chbx').on('change', function(evt) {
if ($("input[name='choice[]']:checked").length > limit) {
this.checked = false;
}
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" name="formname" method="post" autocomplete="off" id="update">
<div class="group" style="margin:0.5em 0;">
<div>
<div id="one">

I have created a fiddle for you demonstrating my solution.
I changed the way you're handling this to be more visual to the user with what is happening by actually disabling the other checkboxes.
I added new classes to all of the checkboxes that only allow one selection, and added a separate class to the checkboxes that allow two selections.
After that you just need to check the class of the clicked checkbox, and disable the others depending on whether or not it was a select-one or select-two checkbox:
var canOnlySelectOne = $(this).hasClass("select-one");
if (canOnlySelectOne) {
$(".sing-chbx").not(this).attr("disabled", this.checked);
} else if ($(this).hasClass("select-two")) {
if ($(".select-two:checked").length > 0) {
$(".select-one").attr("disabled", true);
} else {
$(".select-one").attr("disabled", this.checked);
}
}
We simply enable/disable the other checkboxes based on whether or not the clicked one (this) is checked or not. If the checkbox has a class of select-two then we check if any of the select-two checkboxes are checked, and act accordingly.

Instead of preventing user to check - just uncheck prev selection
You have 3 cases: 03 is clicked, 04 is clicked, something else clicked
Here is the updated code:
$(function() {
$('#submit').click(function() {
checked = $("input[type=checkbox]:checked").length;
if (!checked) {
alert("You must check at least one reason.");
return false;
}
});
});
// No more than 1 checkbox allowed except 3 & 4
$('input.sing-chbx').on('change', function(evt) {
var me = $(this).val();
$('input.sing-chbx').each(function(ix){
var el = $(this);
if(el.val()!= me) {
if(me == "03") {
// case 1: me == '03' - disable all but '04'
if( el.val() != "04") {
el.prop('checked', false);
}
} else if(me == "04") {
// case 2: me == '04' - disable all but '03'
if(el.val() != "03") {
el.prop('checked', false);
}
} else {
// otherwise disable all
el.prop('checked', false);
}
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form action="" name="formname" method="post" autocomplete="off" id="update">

Checking to see if a checkbox is selected before searching

I am having some trouble with my checkboxes. I am trying to get a returned true or false value out of event listeners on checkboxes and then passing it through an event listener on a button to confirm that at least one checkbox is selected. I'm sorry if this sounds confusing and I feel like there is an easier way to do this. I would like to solve this with pure JavaScript. Really appreciate the help. Below is the code.
<body>
<script src="racquetObjects.js"></script>
<div class="mainContainer">
<div class="selectors">
<form action="">
<div class="checkboxes">
<input type="checkbox" id="babolat" value="Babolat" />
<label for="babolat">Babolat</label>
<input type="checkbox" id="wilson" value="Wilson" />
<label for="wilson">Wilson</label>
<input type="checkbox" id="power" value="Power" />
<label for="power">Power</label>
<input type="checkbox" id="control" value="Control" />
<label for="control">Control</label>
<input type="checkbox" id="popular" value="Popular" />
<label for="popular">Popular</label>
</div>
<button type="button" id="find">Find</button>
</form>
</div>
<div class="racquetContainer"></div>
<div class="bench"></div>
</div>
<script src="racquetFinderCB.js"></script>
<script src="racquetFinder.js"></script>
</body>
const findButton = document.querySelector("#find");
const checkboxes = document.querySelectorAll(
".checkboxes input[type=checkbox]"
);
const checkboxesAreChecked = checkboxes.forEach((el) => {
el.addEventListener("click", (e) => {
if (e.target.checked) {
return true;
} else {
return false;
}
});
});
const beforeSubmit = () => {
if (checkboxesAreChecked === true) {
console.log("Time to search!");
} else {`enter code here`
console.log("You need to select an option");
}
};
In this example there is an event listener for the form submit. An array of the input elements is filtered, so only the checked will end up in checked.
The first e.preventDefault() is just for testing. If the form should submit (something was checked) then remove that line of code.
document.forms.find.addEventListener('submit', e => {
let inputs = e.target.querySelectorAll('input');
e.preventDefault(); // prevent default to test what happens
let checked = [...inputs].filter(input => input.checked);
if (checked.length > 0) {
console.log('at least one was checked');
} else {
e.preventDefault(); // prevent default to stop the form action
console.log('none was checked');
}
});
<div class="mainContainer">
<div class="selectors">
<form name="find" action="">
<div class="checkboxes">
<input type="checkbox" id="babolat" value="Babolat" />
<label for="babolat">Babolat</label>

jQuery: How to uncheck random checkboxes in div after checking all?

When onClick on link occurs, all checkboxes present in that div are checked.
function initSelectAll() {
$("form").find("a.selectAll").click(function() {
var cb = $(this).closest("div").find("input[type=checkbox]");
cb.not(":checked").click().length || cb.click();
//........WANT TO UNCHECK checkboxes with class="file" where link id is 'id="ninapaya"'; how to do that?......
return false;
});
}
initSelectAll();
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<form>
<div>
Select
<span class="kukapaya">(alle)</span>
<br>
<input type="checkbox" class="document" name="check2">
<input type="checkbox" class="document" name="check2">
<br>
<input type="checkbox" class="File">
<input type="checkbox" class="File">
</div>
</form>
Requirement: We should not check the checkboxes with class="File".
JSFiddle: https://jsfiddle.net/k4d6zpay/
It could be simplified using .prop(.prop( propertyName, function )) and using :not selector
$("form").find("a.selectAll").click(function() {
$(this).closest("div").find("input[type='checkbox']:not('.File')").prop('checked', function() {
return !this.checked;
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<form>
<div>
Select
<span class="kukapaya">(alle)</span>
<br>
<input type="checkbox" class="document" name="check2">
<input type="checkbox" class="document" name="check2">
<br>
<input type="checkbox" class="File">
<input type="checkbox" class="File">
</div>
</form>
try this:
function initSelectAll() {
$("form").find("a.selectAll").click(function() {
var cb = $(this).closest("div").find("input[type=checkbox]");
cb.not(":checked").not('.File').click().length || cb.click();
return false;
});
}
initSelectAll();
Also update in your jsfiddle link: https://jsfiddle.net/k4d6zpay/1/
function initSelectAll() {
$("form").find("a.selectAll").click(function() {
var cb = $(this).closest("div").find("input[type=checkbox]:not(.File)");
cb.not(":checked").click().length || cb.click();
//........WANT TO UNCHECK checkboxes with class="file" where link id is 'id="ninapaya"';
$(this).closest("div").find("input[type=checkbox][id='ninapaya'].File").prop('checked',false);
return false;
});
}
initSelectAll();

How to select all fields from a single box?

I have this sample:
link
CODE HTML:
<div class="box1">
<fieldset>
<input type="checkbox" class="select-all">
<label>Select All </label>
</fieldset>
<fieldset>
<input type="checkbox">
<label>Checkbox1</label>
</fieldset>
<fieldset>
<input type="checkbox">
<label>Checkbox3 </label>
</fieldset>
<fieldset>
<input type="checkbox">
<label>Checkbox3 </label>
</fieldset>
</div>
<div class="box2">
<fieldset>
<input type="checkbox" class="select-all">
<label>Select All </label>
</fieldset>
<fieldset>
<input type="checkbox">
<label>Checkbox4 </label>
</fieldset>
<fieldset>
<input type="checkbox">
<label>Checkbox5 </label>
</fieldset>
<fieldset>
<input type="checkbox">
<label>Checkbox6 </label>
</fieldset>
</div>
CODE CSS:
.box1{
background:#d9d9d9;
margin-bottom:20px;
}
.box2{
background:#ccc;
}
CODE JS:
$('.select-all').click(function(event) {
if(this.checked) {
// Iterate each checkbox
$(':checkbox').each(function() {
this.checked = true;
});
}else{
$(':checkbox').each(function() {
this.checked = false;
});
}
});
What I want to do is that when the button "select-all" is checked, select all fields in a box.
At this time, set all inputs ... and I wish only the current box.
How can I change my function so that it works?
Thanks in advance!
You can use .closest() to find the parent div, then use .find() method to get the checkboxes inside it,
$('.select-all').click(function(event) {
if (this.checked) {
// Iterate each checkbox
$(this).closest("div").find(':checkbox').each(function() {
this.checked = true;
});
} else {
$(this).closest("div").find(':checkbox').each(function() {
this.checked = false;
});
}
});
Demo
You can reduce your code like this also,
$('.select-all').click(function(event) {
var obj=this;
var parent = $(this).closest("div[class^=box]");
parent.find(':checkbox').each(function() {
this.checked = obj.checked;
});
});
As A.Wolf suggested, you can use like this too,
$('.select-all').change(function(event) {
$(this).closest('div[class^=box]').find(':checkbox').prop('checked', this.checked);
});

Not able to hide, show button based on radio button select using JQuery

I have 6 groups of radio buttons with three choices each and a button to the next step. I want that a radio button in each group must be selected before the button to the next step is displayed. The button to the next step is hidden by default. It concerns a wordpress site and the code is provided by a plugin named: quform
The html code (1 group):
<div class="iphorm-group-row iphorm-clearfix iphorm-group-row-1cols"><div class="iphorm-element-wrap iphorm-element-wrap-radio iphorm_14_12-element-wrap iphorm-clearfix iphorm-labels-above iphorm-element-optional" style="display: block;">
<div class="iphorm-element-spacer iphorm-element-spacer-radio iphorm_14_12-element-spacer">
<label class="iphorm_14_12-outer-label">Group1</label>
<div class="iphorm-input-wrap iphorm-input-wrap-radio iphorm_14_12-input-wrap">
<div class="iphorm-input-ul iphorm-input-radio-ul iphorm_14_12-input-radio-ul iphorm-options-block iphorm-clearfix">
<div class="iphorm-input-li iphorm-input-radio-li iphorm_14_12-input-li">
<label class="iphorm_14_12_1_label">
<div class="radio" id="uniform-iphorm_14_12_523933240794b_1"><span><input type="radio" value="Level-1" id="iphorm_14_12_523933240794b_1" name="iphorm_14_12" class="iphorm-element-radio iphorm_14_12 iphorm_14_12_1"></span></div>
Level-1</label>
</div>
<div class="iphorm-input-li iphorm-input-radio-li iphorm_14_12-input-li">
<label class="iphorm_14_12_2_label">
<div class="radio" id="uniform-iphorm_14_12_523933240794b_2"><span><input type="radio" value="Level-2" id="iphorm_14_12_523933240794b_2" name="iphorm_14_12" class="iphorm-element-radio iphorm_14_12 iphorm_14_12_2"></span></div>
Level-2</label>
</div>
<div class="iphorm-input-li iphorm-input-radio-li iphorm_14_12-input-li">
<label class="iphorm_14_12_3_label">
<div class="radio" id="uniform-iphorm_14_12_523933240794b_3"><span><input type="radio" value="Level-3" id="iphorm_14_12_523933240794b_3" name="iphorm_14_12" class="iphorm-element-radio iphorm_14_12 iphorm_14_12_3"></span></div>
Level-3</label>
</div>
</div>
</div>
<div class="iphorm-errors-wrap iphorm-hidden">
</div> </div>
The Javascript code (6 groups):
$(".iphorm_14_12, .iphorm_14_13, .iphorm_14_14, .iphorm_14_15, .iphorm_14_16, .iphorm_14_17").click(function(){
var show = true;
$(".iphorm_14_12, .iphorm_14_13, .iphorm_14_14, .iphorm_14_15, .iphorm_14_16, .iphorm_14_17").each(function () {
if (!$(this).is(':checked')){
show = false;
}
$(".iphorm_14_12_1, .iphorm_14_12_2, .iphorm_14_12_3, .iphorm_14_13_1, .iphorm_14_13_2, .iphorm_14_13_3, .iphorm_14_14_1, .iphorm_14_14_2, .iphorm_14_14_3, .iphorm_14_15_1, .iphorm_14_15_2, .iphorm_14_15_3, .iphorm_14_16_1, .iphorm_14_16_2, .iphorm_14_16_3, .iphorm_14_17_1, .iphorm_14_17_2, .iphorm_14_17_3").each(function () {
if (!$(this).is(':checked')) {
show = false;
}
if (show) {
$('#btn-step-6').show();
} else {
$('#btn-step-6').hide();
}
});
});
});
Wrap each radio groups with a form or a div :
<div id="food">
<input type="radio" name="group1" value="Milk"> Milk
<input type="radio" name="group1" value="Butter"> Butter
<input type="radio" name="group1" value="Cheese"> Cheese
</div>
<div id="pets">
<input type="radio" name="group2" value="Dog"> Dog
<input type="radio" name="group2" value="Cat"> Cat
<input type="radio" name="group2" value="Dolphin"> Dolphin
</div>
Then in jQuery :
if ($('#food input[type=radio]:checked')[0] != undefined && $('#pets input[type=radio]:checked')[0] != undefined) {
$('#btn-step-6').show();
}
Try this:
<select name="top5" size="3">
<option onclick="showNextStep(this)">Checkbox</option>
</select>
in showNextStep(obj):
// The id of the hidden element -> displaly: none
if ($(obj).prop('checked')) {
$("#nextstep").css('display', "block");
} else {
// To hide if unselect
$("#nextstep").css('display', "none");
}
You can try jsfiddle example (http://jsfiddle.net/Lt92r/), I hope this will help.
$(".test input[type=radio]").click(function(){
$(this).parent("div").find(".btn").css("display","block");
});

Display Checkboxes on Click of a button

I have a button Resend , and on click of it , the checkboxes get enable against the following:
id="AlertSent"
id="AlertNotSent"
id="AlertInProgress"
Now the DIV Code for Above mentioned DIVS is as below
<div class="span9">
<div class="row-fluid">
<div id="enableCheckBox" class ="span12">
<input type="checkbox" id="checkbox1" name="checkbox1"/>
</div>
<div id="AlertSent" class="span12">
<label><spring:message code='alert.sent' />:</label>
</div>
</div>
<div class="row-fluid">
<div id="enableCheckBox" class ="span12">
<input type="checkbox" id="checkbox2" name="checkbox2"/>
</div>
<div id="AlertNotSent" class="span12">
<label><spring:message code='alert.not.sent'/>:</label>
</div>
</div>
<div class="row-fluid">
<div id="enableCheckBox" class ="span12">
<input type="checkbox" id="checkbox3" name="checkbox3" class="required" />
</div>
<div id="AlertInProgress" class="span12">
<label> <spring:message code='alert.in.progress' />:</label>
</div>
</div>
</div>
The button Code for Resend and Done is
<input type="button" value="button" id="resend"/>
<input type="button" value="button" id="done"/>
The JQuery Code is
var j$ = jQuery.noConflict();
j$(document).ready(function() {
var resendbtn = j$('#resend');
var allChkBox = j$('input[name="enableCheckBox"]');
var verifyChecked = function() {
if ! $('#resend').click {
allChkBox.attr('disabled', 'disabled');
} else {
allChkBox.removeAttr('disabled');
}
};
verifyChecked();
resendbtn.change(verifyChecked);
});
The requirement is on click of Resend, the checkboxes appear against above DIVS (AlertSent, AlertNotSent and AlertInProgress), and the Resend button Becomes Done, and if a User unchecks all the checkboxes then the Done Button becomes Resend again.
How do I write a JQuery/JavaScript code to achieve above?
Please suggest
It's hard to know exactly what you want here, but perhaps this will get you started:
http://jsfiddle.net/ZqH7B/
to handle showing the checkboxes:
$("#resend").on( 'click', function () {
$('.enableCheckBox').css('visibility', 'inherit');
$(this).hide().next().show();
$('input:checkbox').prop('checked', true);
});
to handle uncheck behavior:
$('input[type=checkbox]').on( 'change', function() {
var num = $('input:checked').length;
if ( num == 0 ) { $('#resend').show().next().hide(); }
});
Try following code:
HTML:
<input type="checkbox" class="chk">
<input type="button" value="Resend" class="toggle">
JS:
$(document).ready(function(){
$(".chk").prop("checked","checked");
$(".chk").css('display','none');
$(".toggle").click(function(){
$(".chk").css('display','block');
$(".chk").prop("checked","checked");
$(this).val("Done");
});
$(".chk").change(function(){
var all = $(".chk").length;
var chked = $(".chk").not(":checked").length;
if(all == chked){
$(".chk").css('display','none');
$(".toggle").val("Resend");
}
})
});
