Radio button is showing div on selection but not hiding after selecting a different radio button

I have three divs I want to show based on a radio selection. I've written the below script, but the problem I've run into is the div doesn't hide after a different radio button is selected. I'm using ucalc so I can't change the class names or ids of the divs or the radio buttons so have to work with that.
Note, the radio button is automatically selected when the form loads so the first div needs to be showing initially.
Code below:
$(document).ready(function(){
// First Div/Radio Button
$('#input_radio-30-0-des').on('change', function(){
var a = $(this).prop('checked');
if(a) {
$("#grid-40-42").show();
} else {
$("#grid-40-42").hide();
}
});
// Second Div/Radio Button
$("#grid-44-46").hide();
$('#input_radio-30-1-des').on('change', function(){
var a = $(this).prop('checked');
if(a) {
$("#grid-44-46").show();
} else {
$("#grid-44-46").hide();
}
});
// Third Div/Radio Button
$("#grid-46-48").hide();
$('#input_radio-30-2-des').on('change', function(){
var a = $(this).prop('checked');
if(a) {
$("#grid-46-48").show();
} else {
$("#grid-46-48").hide();
}
});
});
I'm not very familiar with writing javascript (you can probably tell!) so an explanation for 'dummies' would be appreciated!
Thank you for your help!

You need to hide 2nd & 3rd div by CSS and when user change other button then find ID so according to ID show that div and rest div will hide as below snippet.
$(document).ready(function(){
$('#input_radio-30-0-des, #input_radio-30-1-des, #input_radio-30-2-des').on('change', function(){
var getid = $(this).attr('id');
if (getid=='input_radio-30-0-des') {
$('#grid-44-46, #grid-46-48').hide()//2nd and 3rd div hide
$("#grid-40-42").show();
}
if (getid=='input_radio-30-1-des') {
$('#grid-40-42, #grid-46-48').hide()//1st and 3rd div hide
$("#grid-44-46").show();
}
if (getid=='input_radio-30-2-des') {
$('#grid-40-42, #grid-44-46').hide()//1st and 2rd div hide
$("#grid-46-48").show();
}
})
});
#grid-44-46, #grid-46-48{display: none;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<label><input type="radio" name="div-show-hide" id="input_radio-30-0-des" checked> Button One</label>
<label><input type="radio" name="div-show-hide" id="input_radio-30-1-des"> Button Two</label>
<label><input type="radio" name="div-show-hide" id="input_radio-30-2-des"> Button Three</label>
<div id="grid-40-42"><h2>Show - Div One</h2></div>
<div id="grid-44-46"><h2>Show - Div Two</h2></div>
<div id="grid-46-48"><h2>Show - Div Three</h2></div>

Use wild card to hide all <div> which id start with grid- on radio change.
$("[id^=grid-]").hide();
$('#input_radio-30-0-des').on('change', function() {
$("[id^=grid-]").hide();
var a = $(this).prop('checked');
if (a) {
$("#grid-40-42").show();
} else {
$("#grid-40-42").hide();
}
});
$('#input_radio-30-1-des').on('change', function() {
$("[id^=grid-]").hide();
var a = $(this).prop('checked');
if (a) {
$("#grid-44-46").show();
} else {
$("#grid-44-46").hide();
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type='radio' id='input_radio-30-0-des' name="group1" />
<div id='grid-40-42'>grid-40-42</div>
<input type='radio' id='input_radio-30-1-des' name="group1" />
<div id='grid-44-46'>grid-40-46</div>
Note
No need multi-pal $(document).ready(function(){ .
Id must be unique.

I'm using a Javascript object to match each Radio button with it's targeted div.
I assume they are hidden by default. Just having fun and giving an alternative to multiple checks! A cleaner code also where you could easily setup all those confusing names...
$( document ).ready(function() {
let matches = {
"input_radio-30-0-des": 'grid-40-42',
"input_radio-30-1-des": 'grid-44-46',
"input_radio-30-2-des": 'grid-46-48'
};
$(":input[name='FM']").on("change", function () {
var target= matches[$(this).attr('id')];
$('#' +target).toggle($(this).checked);
$("[id^=grid-]").not('#' +target).hide();
})
});
div[id*='grid-'] { display: none; }
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="radio" name="FM" id="input_radio-30-0-des" value="0"/>
<label for="input_radio-30-0-des">0</label>
<input type="radio" name="FM" id="input_radio-30-1-des" value="1"/>
<label for="input_radio-30-1-des">1</label>
<input type="radio" name="FM" id="input_radio-30-2-des" value="2"/>
<label for="input_radio-30-2-des">2</label>
<div id="grid-40-42">40-42</div>
<div id="grid-44-46">44-46</div>
<div id="grid-46-48">46-48</div>

How to add / modify existing jquery functionality

I'm trying to disable/enable a button based on the checkbox, which I am unable to do. Here is the sample I worked on. For enabled and disabled, different buttons have to be used.
function toggleContinue() {
$(document).ready(function() {
$("#swpRequired").click(function() {
$("input,select").change(function() {
$("#disableContinue").attr("style", "display:inline-block");
$("#continueButton").attr("style", "display:none");
});
});
$("#swpRequired").click(function() {
$("input,select").change(function() {
$("#disableContinue").attr("style", "display:none");
$("#continueButton").attr("style", "display:inline-block;");
});
});
});
}

Try this. use prop method of jquery
function s()
{
if($("#a").prop('disabled')==false)
$("#a").prop('disabled','true')
else
$("#a").removeAttr('disabled')
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" onchange="s()" id="b"/>enable
<input type="button" value="click" id="a">

You could use attr() to disable/enable the button based on checkbox's value:
$(document).ready(function() {
$("#swpRequired").click(function() {
$("#continueButton").attr("disabled", this.checked);
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" id="swpRequired" />
<button id="continueButton">continue</button>

You can use change event and take the help of disabled property of button.
Solution will be like:
$(document).on('change', "#checkbox", function()
{
if ($(this).prop("checked") == true)
{
$("#btn").prop('disabled',true)
}
else
{
$("#btn").prop('disabled',false)
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" id="checkbox"/>enable
<input type="button" value="click" id="btn">

Checkbox Hidden Div Unchecked

I have a checkbox hidden div with text field. If checkbox is checked this text field will showed, but if checkbox unchecked text field not show. This Code :
<script type="text/javascript">
$(function () {
$("input[name='checkbox1']").click(function () {
if ($("#checkyes1").is(":checked")) {
$("#dvcheckbox1").show('lainnya');
} else {
$("#dvcheckbox1").hide('lainnya');
}
});
});
</script>
<div style="margin-left: 29%; margin-top: -2%;">
<label for="checkyes1">
<input type="checkbox" id="checkyes1" name="checkbox1" value="lainnya" />
Lainnya
</label>
<div id="dvcheckbox1" style="display: none;">
<?php echo $form->textField($model,'lainnya'); ?>
</div>
</div>
But, How this checkbox is checked if there something value on textfield? and text field shown. Because in form Update, value was show but checkbox is checked. I want checkbox is checked
For example Like this:
Click to show example

Instead use with change event with .toggle(boolean) method:
// on page load check of the div contains any text
$("#dvcheckbox1").toggle(function(){
var $v = $(this).find('input').val();
$("input[name='checkbox1']").prop('checked', $v.trim().length !== 0)
return $v.trim().length !== 0;
});
$("input[name='checkbox1']").change(function () {
$("#dvcheckbox1").toggle(this.checked);
});

There are a few things here:
1 - Better if you use document ready, because it waits until all the elements are loaded.
2 - You should hide the element$("#dvcheckbox1").hide('lainnya') when the page is loaded.
3 - A listener in the input:text is a good idea. It enables the checkbox if the textbox is empty.
Please, have a look at the next piece of code:
<div>
<label for="checkyes1">
<input type="checkbox" id="checkyes1" name="checkbox1" value="lainnya" />
Lainnya
</label>
<div id="dvcheckbox1">
<label for="myValuye"/>
<input type="text" id="myValue" name="myValue" value=""/>
</div>
</div>
<script>
$(document).ready(function() {
$("input[name='checkbox1']").click(function () {
// Always use some logs to check what line are you reaching.
console.log("Clicked checkbox!!!");
if ($("#checkyes1").is(":checked")) {
$("#dvcheckbox1").show('lainnya');
} else {
console.log("Value: " + $("#myValue").val());
$("#dvcheckbox1").hide("lainnya");
}
});
$("#myValue").bind("change paste keyup", function() {
if ($(this).val() == "") {
$("#checkyes1").removeAttr("disabled");
} else {
$("#checkyes1").attr("disabled", true);
}
});
// First of all we hide the #dvcheckbox1
$("#dvcheckbox1").hide('lainnya');
})

jquery radio button click and change function not working

I want to hide and show div according to radio buttons value.
HTML code is,
<div id="share_to_others">
<input type="radio" value="33" id="fx_sharepl_type" name="fx_sharepl_type">
<input type="radio" value="22" id="fx_sharepl_type" name="fx_sharepl_type">
<input type="radio" value="11" id="fx_sharepl_type" name="fx_sharepl_type">
</div>
And jquery code that i tried is,
$("#share_to_others input[name='fx_sharepl_type']").click(function () {
alert("test");
});
$("#share_to_others input[name='fx_sharepl_type']").change(function () {
alert("test");
});
$("#fx_sharepl_type").change(function () {
alert("asdas");
});
$("input[name=fx_sharepl_type]:radio").change(function () {
alert("click fired");
});
$(document).on('change', 'input:radio[name=fx_sharepl_type"]', function (event) {
alert("click fired");
});
Many of them from jsfiddle working demo, But not working for me, i dont know why.
Am i doing anything wrong?

You have to give unique id to each radio button then after do like this way.
$("#r1, #r2, #r3").change(function () {

$(function() { // DOM loaded event handler
var show_duration = 0;
var content_33 = $("#content_33");
var content_22 = $("#content_22");
var content_11 = $("#content_11");
var bloc_radio_share = $("#share_to_others");
// Take an html element in parameter and show it
function show_content(content_id) {
content_id.show(show_duration);
}
// Take an html element in parameter and hide it
function hide_content(content_id) {
content_id.hide(0);
}
hide_content(content_22);
hide_content(content_11);
bloc_radio_share.change(function() {
var radio_checked_val = $('input[name=fx_sharepl_type]:checked', '#share_to_others').val();
if (radio_checked_val == 33) {
hide_content(content_22);
hide_content(content_11);
show_content(content_33);
}
else if (radio_checked_val == 22) {
hide_content(content_33);
hide_content(content_11);
show_content(content_22);
}
else { // case content == 11
hide_content(content_33);
hide_content(content_22);
show_content(content_11);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div id="share_to_others">
<label>
<input type="radio" value="33" id="fx_sharepl_type" name="fx_sharepl_type" checked />
33
</label>
<label>
<input type="radio" value="22" id="fx_sharepl_type" name="fx_sharepl_type" />
22
</label>
<label>
<input type="radio" value="11" id="fx_sharepl_type" name="fx_sharepl_type" />
11
</label>
</div>
<div id="content_33">
This div is displayed because of click on radio button 33
</div>
<div id="content_22">
Radio button 22 has been clicked so I appear
</div>
<div id="content_11">
If you click on radio button 11 you'll see me, like now
</div>
Here is an example of algorithm that fits your need. Logic may be not the best or the fastest but that is a begin.

Your code wors but you forgot to include a JQuery source version located to the left side of the JSFiddle window.
Selecting any version of JQuery will make your code work.

Create "check all" / "select all" checkbox with jQuery?

I have few checkboxes , out of which one is "Select All" and the others are some standalone's.
The requirement is that
Ifthe user click on "Select All" checkbox, then all other checkboxes will be checked.
If he unchecks the "Select All" checkbox , then everything will be unchecked.
And if any one of the individual checkbox is unchecked, then the "Select all" will be unchecked.
If all the four check boxes are checked, then the "Select All" will be checked.
I am using JQuery. I am able to achieve the first two but not the last two. My code is as under
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE> Check / UnCheck All Checkbox </TITLE>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript">
function SelectDeselect()
{
if(document.getElementById('chkSelectDeselectAll').checked) $("INPUT[type='checkbox']").attr('checked',true);
else $("INPUT[type='checkbox']").attr('checked',false);
}
</script>
</HEAD>
<BODY>
<input type="checkbox" id="chkSelectDeselectAll" onClick="SelectDeselect()">Select All
<br><br>
Select your hobbies:
<br><br>
<input type="checkbox" id="chkTV">Watching T.V.<br><br>
<input type="checkbox" id="chkGardening">Gardening<br><br>
<input type="checkbox" id="chkSwimming">Swimming<br><br>
<input type="checkbox" id="chkChess">Playing Chess<br><br>
</BODY>
</HTML>
Need help to implement the rest.
Thanks

CHeck Fiddle: http://jsfiddle.net/4vKwm/10/

maybe it gives some explanations
Ifthe user click on "Select All" checkbox, then all other checkboxes will be checked.
$("#chkSelectDeselectAll").click(function(){
if($("#chkSelectDeselectAll").is(':checked'))
{
("checkbox").each(function(){
$(this).attr('checked', 'checked');
});
}
});
If he unchecks the "Select All" checkbox , then everything will be unchecked.
$("#chkSelectDeselectAll").click(function(){
if(!$("#chkSelectDeselectAll").is(':checked'))
{
("checkbox").each(function(){
$(this).removeAttr('checked');
});
}
});
And if any one of the individual checkbox is unchecked, then the "Select all" will be unchecked.
$("checkbox").click(function(){
("checkbox").each(function(){
if($(this).is(':checked'))
{
$("#chkSelectDeselectAll").removeAttr('checked');
}
});
});
If all the four check boxes are checked, then the "Select All" will be checked.
$("checkbox").click(function(){
("checkbox").each(function(){
var yesno=true;
if(!$(this).is(':checked'))
{
yesno=false;
}
});
if( yesno)
{
$("#chkSelectDeselectAll").attr('checked', 'checked')
}
});

I would really recommend you to update your jQuery library and try to add a class to all the checkboxes you want to listen to, but:
var collection = $("input:checkbox:not(#chkSelectDeselectAll)").change(function() {
selectAll[0].checked = collection.filter(":not(:checked)").length === 0;
});
var selectAll = $("#chkSelectDeselectAll").change(function(){
collection.attr('checked', this.checked);
});
will work, I added the feature if you manually check all (or deselect one when you pushed select all) then it will toggle off the #chkSelectDeselectAll. A demo:
http://jsfiddle.net/voigtan/yTWKY/1/

Simply check the state of all checkboxes.
Working Demo: http://jsfiddle.net/XSdjQ/1/
Updated Demo: http://jsfiddle.net/XSdjQ/2/
Yet another Demo that works nicely with your markup: http://jsfiddle.net/XSdjQ/3/

You can try this code.
$(document).ready(function(){
$('#chkSelectDeselectAll').toggle(function(){
$('input[type=checkbox]').each(function(){
$(this).attr('checked',true);
});
},function(){
$('input[type=checkbox]').each(function(){
$(this).removeAttr('checked');
});
})
});
Thanks.
