How do I Select All Checkboxes When First Radio Input Selected & Uncheck All Checkboxes when Second radio input selected? (Javascript)

how do I select all checkboxes when the first radio input is selected & uncheck all checkboxes when the second radio input is selected? (Javascript)?
I've looked into previous similar questions on here, but they all seem to be about using checkboxes rather than radio buttons, or there aren't ways to unselect.
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3

Get a list of HTML nodes by class using document.querySelectorAll(). Iterate the radios list using NodeList.forEach(), and add a change event listener to each radio button. Whenever the listener is called, iterate the checkboxes array with NodeList.forEach(), and update the checked value of each element:
var checkboxes = document.querySelectorAll('.custom-selector');
var radios = document.querySelectorAll('.permission');
radios.forEach(function(el) {
el.addEventListener('change', function(e) {
var checked = el.value === 'select';
checkboxes.forEach(function(el) {
el.checked = checked;
});
});
});
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3

You can do it using JQuery.
$('.permission').click(function() {
$('.custom-selector').prop('checked', $(this).val() == 'select');
});
See below Code Snippet
$('.permission').click(function() {
$('.custom-selector').prop('checked', $(this).val() == 'select');
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3

function handleChange(e) {
if (e.target.value == "select") {
handleCheckUncheck(true);
}
if (e.target.value == "deselect") {
handleCheckUncheck(false);
}
}
function handleCheckUncheck(value) {
document.querySelectorAll("input[type='checkbox']").forEach(function(val) {
val.checked = value;
})
}
document.querySelectorAll("input[type='radio']").forEach(function(val) {
val.addEventListener("change", handleChange);
})
<input type="radio" class="permission" name="permission" value="select" /> Select All<br>
<input type="radio" class="permission" name="permission" value="deselect" /> Deselect All<br>
<input type="checkbox" class="custom-selector" /> Checkbox 1
<input type="checkbox" class="custom-selector" /> Checkbox 2
<input type="checkbox" class="custom-selector" /> Checkbox 3

You can do it in a simple way without using jQuery.
Add a checkbox whose status will be set for others.
<label><input type="checkbox" onClick="toggle(this)" /> Select All</label>`
And use this javascript function that will check other checkboxes with the 'custom-selector' class:
function toggle(source) {
checkboxes = document.getElementsByName('custom-selector[]');
for(var i=0, n=checkboxes.length;i<n;i++) {
checkboxes[i].checked = source.checked;
}
}
If someone checks the "Select All" checkbox, all others will also be selected. If it deselects, the effect will be the same.
Regards!

I agree with #OriDrori's answer, You don't need to load jQuery to do such a simple task.

javascript disable a single radio button

I have what should be a problem with a simple solution, and I'm sure I'm just missing something.
I have 2 columns of radio buttons, and when a radio button from a column is clicked, I need to disable the corresponding radio button from the opposite column, so it can't be selected. Then if another button is selected, re-enable the previous button and disable the new opposite selection.
I have given all the radio buttons a unique id. first1, first2, etc. for column one, and second1, second2 etc. for column two.
The way I was headed towards won't work after re-thinking this, and after searching online for an hour, I haven't found a non-jquery way of doing it. Is it possible with javascript?
What I had so far, and I know I'm way off base, but I'm burnt out with the different problems I've had with this page:
function disableForm(theform, theradio) {
//this was a start but does't save valid disabled fields
//it just enables everything
if (document.all || document.getElementById) {
for (i = 0; i < theform.length; i++) {
var formElement = theform.elements[i];
if (true) {
formElement.disabled = false;
}
}
}
document.getElementById(theradio).onclick = function(){
document.getElementById(theradio).disabled=true;
}
}

Let's say you define your radios as
<table style="width: 100%;">
<tr>
<td>
<input id="Radio1_1" type="radio" name="Radio1" onchange="process(this)"/><br />
<input id="Radio1_2" type="radio" name="Radio1" onchange="process(this)"/><br />
<input id="Radio1_3" type="radio" name="Radio1" onchange="process(this)"/><br />
<input id="Radio1_4" type="radio" name="Radio1" onchange="process(this)"/><br />
<input id="Radio1_5" type="radio" name="Radio1" onchange="process(this)"/>
</td>
<td>
<input id="Radio2_1" type="radio" name="Radio2" /><br />
<input id="Radio2_2" type="radio" name="Radio2" /><br />
<input id="Radio2_3" type="radio" name="Radio2" /><br />
<input id="Radio2_4" type="radio" name="Radio2" /><br />
<input id="Radio2_5" type="radio" name="Radio2" />
</td>
</tr>
</table>
Then the goal can be achieved by a simple script:
function process(rb) {
//clearing previos disabled
for (i = 0; i < document.getElementsByName("Radio2").length; i++) {
document.getElementsByName("Radio2")[i].disabled = '';
}
document.getElementById(rb.id.replace('Radio1','Radio2')).disabled='disabled';
}

hide/show checkbox once other checkbox is checked with a condition on its value

I am trying to hide a set of checkbox when one of these is checked, and make them reappear once it is not checked. The conditions must be based on their value.
var input = document.getElementsByTagName("input");
for(i=0;i<input.length;i++){
input[i].onchange = function(){
if(this.checked){
var value = $(this).val();
$("input[type=checkbox]:not(." + '60' + ")").hide();
$("input[type=checkbox]." + '60').show();
}
}
}
The group of checkbox to hide belong to the values 60 and 90 (two arms accessories can't be selected), the idea is that the two checkboxes cannot be selected, just one, so that's why I need to hide one of them once they're checked, and make them reappear once unchecked.
<input type="checkbox" value="50" /> conductive plastic foot cup $50<br/>
<input type="checkbox" value="60" /> <a>T-arms 2 $60</a><br/>
<input type="checkbox" value="90" /> <a>T-arms 1 $90</a><br/>
<input type="checkbox" value="80" /> metal rails $80<br/>
<input type="checkbox" value="30" /> plastic rails $30<br/>
<input type="checkbox" value="70" /> foot rest ring $70<br/>
<input type="checkbox" value="120" />plastic five star foot $120 <br/>
Here is my fiddle: JS fiddle

I'd suggest the following jQuery:
$('.arms').change(
function(){
$('.arms').not(this).prop('disabled',this.checked);
});
Coupled with the amended HTML:
<input id="check1" type="checkbox" value="50" />
<label for="check1">conductive plastic foot cup $50</label>
<input id="check2" type="checkbox" value="60" class="arms" />
<label for="check2">T-arms 2 $60</label>
<input id="check3" type="checkbox" value="90" class="arms" />
<label for="check3">T-arms 1 $90</label>
<input id="check4" type="checkbox" value="80" />
<label for="check4">metal rails $80</label>
<input id="check5" type="checkbox" value="30" />
<label for="check5">plastic rails $30</label>
<input id="check6" type="checkbox" value="70" />
<label for="check6">foot rest ring $70</label>
<input id="check7" type="checkbox" value="120" />
<label for="check7">plastic five star foot $120</label>
JS Fiddle demo.
The above uses the label element, with a for attribute (or property) to associate the text explicitly with the relevant checkbox.
I've added a class to the inputs that are mutually-exclusive in order to easily target them with a selector, which sets the disabled property of the other element (or elements if you add more mutually-exclusive checkboxes) according to whether the checked, or unchecked, element is checked or unchecked.
Incidentally, it's usually better to disable form-fields, rather than removing/hiding them, that way if a user clicks by accident they're not left wondering where the other option's gone to, or surprised when it suddenly reappears.
If, however, you really want to show/hide the 'other' element(s), then you can use the following:
$('.arms').change(
function(){
$('.arms').not(this).add($(this).next())[this.checked ? 'hide' : 'show']();
});
JS Fiddle demo.
Or you can even use the first approach (using the prop('disabled',this.checked)) with the following CSS (in compliant browsers that implement the :disabled pseudo-selector:
input:disabled,
input:disabled + label {
display: none;
}
JS Fiddle demo.

I love the use of data attributes for such kind of stuff:
HTML
<input type="checkbox" value="50" /> conductive plastic foot cup $50<br/>
<input type="checkbox" value="60" data-exclude="input[value=90]" /> T-arms 2 $60<br/>
<input type="checkbox" value="90" data-exclude="input[value=60]" /> T-arms 1 $90<br/>
<input type="checkbox" value="80" /> metal rails $80<br/>
<input type="checkbox" value="30" /> plastic rails $30<br/>
<input type="checkbox" value="70" /> foot rest ring $70<br/>
<input type="checkbox" value="120" />plastic five star foot $120 <br/>
JavaScript
var input = document.getElementsByTagName("input");
$('input').each(function() {
var $input = $(this);
$input.change(function() {
var $exclude = $($input.data('exclude'));
$exclude.toggle(! $input.is(':checked'));
});
});

btw. I'd rather disable the checkbox than hiding it.

Javascript adding values to radio buttons to input price

Im trying to create a javascript block inside of a webpage im working on. I havent done javascript since highschool and it doesnt seem to want to come back to me :(
In this block of code i want to have 4 sets of radio buttons, each time a selection is picked,
a price will be inputed to a variable for each radio group. i.e
var firstPrice = $25
var secondPrice = $56
var thirdPrice = $80
var fourthPrice = $90
then after each radio group has one selection there will be a function attached to the submit button that adds up each price to display the final amount inside of a hidden field
var totalPrice = (firstPrice + secondPrice + thirdPrice + fourthPrice)
My question is, how do i attach a number value to a radio button within a group, same name but id is different in each group. Then do i just create a function that adds all the price groups up and then set the submit button to onClick = totalPrice();
Here is an example of one set of radio buttons:
<label>
<input type="radio" name="model" value="radio" id="item_0" />
item 1</label>
<br />
<label>
<input type="radio" name="model" value="radio" id="item_1" />
item2</label>
<br />
<label>
<input type="radio" name="model" value="radio" id="item_2" />
item3</label>
<br />
<label>
<input type="radio" name="model" value="radio" id="item_3" />
Item4</label>
<br />
<label>
<input type="radio" name="model" value="radio" id="item_4" />
item5</label>
</form>
then my script looks something like:
function finalPrice90{
var selectionFirst = document.modelGroup.value;
var selectionSecond = document.secondGroup.value;
var selectionThird = document.thirdGroup.value;
var selectionFourth = document.fourthGroup.Value;
var totalPrice = (selectionFirst + selectionSecond + selectionThird + selectionFourth);
}

Set the value attribute of your radio inputs to the price each radio button should represent.
When it's time to calculate, simply loop through each group and get the value attribute if the checked radio.
Because the value attribute is a string representation of a number, you'll want to convert it back to a number before doing any math (but that's a simple parseInt or parseFloat).
Here's a working fiddle using pure JavaScript: http://jsfiddle.net/XxZwm/
A library like jQuery or Prototype (or MooTools, script.aculo.us, etc) may make this easier in the long run, depending on how much DOM manipulation code you don't want to re-invent a wheel for.

Your requirements seem pretty simple, here's an example that should answer most questions. There is a single click listener on the form so whenever there is a click on a form control, the price will be updated.
<script type="text/javascript">
//function updatePrice(el) {
function updatePrice(event) {
var el = event.target || event.srcElement;
var form = el.form;
if (!form) return;
var control, controls = form.elements;
var totalPrice = 0;
var radios;
for (var i=0, iLen=controls.length; i<iLen; i++) {
control = controls[i];
if ((control.type == 'radio' || control.type == 'checkbox') && control.checked) {
totalPrice += Number(control.value);
}
// Deal with other types of controls if necessary
}
form.totalPrice.value = '$' + totalPrice;
}
</script>
<form>
<fieldset><legend>Model 1</legend>
<input type="radio" name="model1" value="25">$25<br>
<input type="radio" name="model1" value="35">$35<br>
<input type="radio" name="model1" value="45">$45<br>
<input type="radio" name="model1" value="55">$55<br>
</fieldset>
<fieldset><legend>Model 2</legend>
<input type="radio" name="model2" value="1">$1<br>
<input type="radio" name="model2" value="2">$2<br>
<input type="radio" name="model2" value="3">$3<br>
<input type="radio" name="model2" value="4">$4<br>
<fieldset><legend>Include shipping?</legend>
<span>$5</span><input type="checkbox" value="5" name="shipping"><br>
</fieldset>
<input name="totalPrice" readonly><br>
<input type="reset" value="Clear form">
</form>
You could put a single listener on the form for click events and update the price automatically, in that case you can get rid of the update button.

AJAX multiple checkboxes / multiselect

Alrighty then, howdy first off; quick question I have a form that has multiple check boxes with the same name (i.e. -
<input type="checkbox" name="myname[]" value="1" />
<input type="checkbox" name="myname[]" value="1" />
<input type="checkbox" name="myname[]" value="2" />
<input type="checkbox" name="myname[]" value="3" />
<input type="checkbox" name="myname[]" value="4" />
)
I am not using JQuery as I don't need that much baggage it is a very simple script that does does what is says on the tin, just serialize a form for use in an ajax post request. I would like to know though how to serialize the multiple checkboxes above for correct use in php.

I think the easiest way would be to grab all the checkboxes with document.getElementsByName and loop to get what's checked.
var checkedValues = [];
var allCheckboxes = document.getElementsByName("myname[]");
for(var i = 0; i < allCheckboxes.length; i++){
if (allCheckboxes[i].checked)
checkedValues.push(allCheckboxes[i].value);
}
I assume PHP can treat a comma-delimited list of values as an array:
checkedValues.join(); //tested and produces ---> 0,3,4
