So i have checkboxlist
<input type="checkbox" name="colorc" value="black" />Black<br/><br>
<input type="checkbox" name="colorc" value="brown" />Brown<br/><br>
<input type="checkbox" name="colorc" value="white" />White<br/><br>
<input type="button" id="btnClick" value="Color Change"></button>
and when i press button, checkmark moves to next checkbox, the same i want if we have two checkmarks, but without using JQuery, clear JS. Thanks
I guess this would do:
document.getElementById("btnClick").onclick = function(){
var checkBoxes = document.getElementsByName("colorc");
var checked = checkBoxes[checkBoxes.length - 1].checked;
for(var i = checkBoxes.length-1; i > 0; --i){
checkBoxes[i].checked = checkBoxes[i-1].checked;
}
checkBoxes[0].checked = checked;
}
Demo: http://jsfiddle.net/t231c0ga/1/
The current checked input can be selected as:
input[name=colorc]:checked
The next input can be gotten using the general sibling selector (~):
input[name=colorc]:checked ~ input[name=colorc]
Change your inputs from checkboxes to radio buttons, and use this code. If there's no next input, it defaults to the first input:
document.getElementById('btnClick')
.addEventListener('click',function() {
var next=
document.querySelector(
'input[name=colorc]:checked ~ input[name=colorc]'
) ||
document.querySelector('input[name=colorc]');
next.checked= true;
});
<input type="radio" name="colorc" value="black" checked/>Black<br/><br>
<input type="radio" name="colorc" value="brown" />Brown<br/><br>
<input type="radio" name="colorc" value="white" />White<br/><br>
<input type="button" id="btnClick" value="Color Change"></button>

I'm trying to change the URL when I select radio button.
I have found an answer that works for 'select' form elements, but if I apply it to my radio buttons it lists out all the options instead of the one that is selected
My JS
$('.unitfiltercontrol').change(function(){
var params =[];
$('.unitfiltercontrol').each(function(){
$this=$(this);
if(!$this.val()=='') params.push($this.data('param')+'='+encodeURIComponent( $this.val() ));
});
$('#urlDisplay').text(window.location.href+('?'+params.join('&'))); //print to div for testing
});
My HTML:
<form>
<input id="radio1" type="radio" value="1" name="foo" data-param="foo" class="unitfiltercontrol">
<input id="radio2" type="radio" value="2" name="foo" data-param="foo" class="unitfiltercontrol">
<input id="radio3" type="radio" value="1" name="bar" data-param="bar" class="unitfiltercontrol">
<input id="radio4" type="radio" value="2" name="bar" data-param="bar" class="unitfiltercontrol">
</form>
<div id="urlDisplay"></div>
So if I select radio1, instead of the URL being displayed as:
/?foo=1
I get:
/?foo=1&foo=2&bar=1&bar=2
How would I modify this to work with radio buttons?
Hi friend you can use if condition when pushing parameters to like below
$('.unitfiltercontrol').change(function(){
var params =[];
$('.unitfiltercontrol').each(function(){
$this=$(this);
if ($(this).prop("checked")) { //get the values of only checked radio buttons
if(!$this.val()=='') params.push($this.data('param')+'='+encodeURIComponent( $this.val() ));
}
});
$('#urlDisplay').text(window.location.href+('?'+params.join('&'))); //print to div for testing
});
Radio button in your case make single selection , so no need to loop each radio , just get in the change the value and data for current clicked , then create object using data-param as key , after that loop thorough keys and create and array of key + values as below ; snippet :
let values = {};
$('.unitfiltercontrol').change(function(e){
let data = $(this).data('param');
let value = this.value;
values[data] = value;
let params = [];
let keys = Object.keys(values);
for(inc = 0; inc < keys.length ; inc ++) {
let key = keys[inc];
params.push(key+'='+encodeURIComponent(values[key]))
}
$('#urlDisplay').text(window.location.href+('?'+params.join('&')));
});

My HTML:
<form>
<input id="radio1" type="radio" value="1" name="foo" data-param="foo" class="unitfiltercontrol">
<input id="radio2" type="radio" value="2" name="foo" data-param="foo" class="unitfiltercontrol">
<input id="radio3" type="radio" value="1" name="bar" data-param="bar" class="unitfiltercontrol">
<input id="radio4" type="radio" value="2" name="bar" data-param="bar" class="unitfiltercontrol">
</form>
<div id="urlDisplay"></div>
<div id="urlDisplay">

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.
I was trying to select all yes radio buttons when click on select all, i mean if you click on "yes" and then click on select all must select all fields as yes the same behavior for "no" radio button.
Also i was trying with check-boxes but not sure which is the best ways to achieve it.
<script language="JavaScript">
function selectAll(source) {
checkboxes = document.getElementsByName('bValidation[]');
for(var i in checkboxes)
checkboxes[i].checked = source.checked;
}
<input type="checkbox" name="bValidation" value="Y"> Y
<input type="checkbox" name="bValidation" value="N"> N
<br><input type="checkbox" id="selectall" onClick="selectAll(this)" />Select All
Change this 'bValidation[]' to this 'bValidation'
function selectAll(source) {
checkboxes = document.getElementsByName('bValidation');
for (var i in checkboxes)
checkboxes[i].checked = source.checked;
}
<input type="checkbox" name="bValidation" value="Y"> Y
<input type="checkbox" name="bValidation" value="N"> N
<br><input type="checkbox" id="selectall" onClick="selectAll(this)" />Select All
instead of writing just name in input type, you have to specify name="bValidation[]" in both inputs.
function selectAll(source) {
checkboxes = document.getElementsByName('bValidation[]');
for(var i in checkboxes)
checkboxes[i].checked = source.checked;
}
<input type="checkbox" name="bValidation[]" value="Y"> Y
<input type="checkbox" name="bValidation[]" value="N"> N
<br><input type="checkbox" id="selectall" onClick="selectAll(this)" />Select All
How do you make it calculate using JavaScript/jQuery based on condition:
on radio button 'change' event.
if user clicks "Yes" or "N/A", the value of text boxes with default values next to it will be added and reflected in Total
HTML:
<form>
<fieldset>
<input type="radio" name="remark[]" value="Yes" class="answer">Yes
<input type="radio" name="remark[]" value="No" class="answer">No
<input type="radio" name="remark[]" class="answer">N/A
<input type="text" name="point1" class="score" value="3">
</fieldset>
<fieldset>
<input type="radio" name="remark[]" value="Yes" class="answer">Yes
<input type="radio" name="remark[]" value="No" class="answer">No
<input type="radio" name="remark[]" class="answer">N/A
<input type="text" name="point2" class="score" value="2">
</fieldset>
Total<input type="text" name="total" class="result">
</form>
Vanilla Javascript
Note: these scripts associate with forms that have the class name calc
This script will associate with the form, so if you have multiple instances each form will calculate separately.
Basically for each form select all input's with a value of 'Yes' which are checked, then find the score for that field set and add it to the total
(Demo)
(function(){
"use strict";
function calculate() {
var forms = document.querySelectorAll('.calc'), form, i;
for (i = 0; form = forms[i]; i++) {
var total = 0;
var inputs = form.querySelectorAll('input[value="Yes"]:checked'), input, x;
for (x = 0; input = inputs[x]; x++) {
total += parseFloat(input.parentElement.lastElementChild.value);
}
form.lastElementChild.value = total;
}
}
calculate();
var inputs = document.querySelectorAll('.calc input'), input, x;
for(x = 0; input = inputs[x]; x++) {
input.onchange = calculate;
}
})();
jQuery
If you would like to use jQuery, this is the same script converted to jQuery
(Demo)
(function(){
"use strict";
function calculate() {
$('.calc').each(function(){
var total = 0;
$('input[value="Yes"]:checked', this).each(function(){
total += parseFloat($('input.score', this.parentElement).val());
});
$('input.result', this).val(total);
});
}
calculate();
$('.calc input').on('change', calculate);
})();
Not sure if I understand correctly, but first you'll need a few changes in your markup, radio groups should have different name so it'll be like remark[0] for first group and remark[1] for the second and so on. The "N/A" radios don't seem to have a value so I've added value="NA" to them. So your HTML will look like:
<form>
<fieldset>
<input type="radio" name="remark[0]" value="Yes" class="answer" />Yes
<input type="radio" name="remark[0]" value="No" class="answer" />No
<input type="radio" name="remark[0]" value="NA" class="answer" />N/A
<input type="text" name="point1" class="score" value="3" />
</fieldset>
<fieldset>
<input type="radio" name="remark[1]" value="Yes" class="answer" />Yes
<input type="radio" name="remark[1]" value="No" class="answer" />No
<input type="radio" name="remark[1]" value="NA" class="answer" />N/A
<input type="text" name="point2" class="score" value="2" />
</fieldset>Total
<input type="text" name="total" class="result" />
</form>
Then we just listen to radio's onchange and if Yes or N/A is selected for each group, we have it's value to the total. I used parseInt on values since they're string and it seemed the values were supposed to work as numbers. (2+3 should be 5 and not 23).
$('form input[type=radio]').on('change', function() {
var total = 0;
$('form fieldset').each(function(i) {
var point = parseInt($(this).find('input[type=text]').val());
var val = $(this).children('[name="remark[' + i + ']"]:checked').val();
if(val == "Yes" || val == "NA")
total += point;
});
$('input[name="total"]').val(total);
});
jsfiddle DEMO
When I click a button I want to get the value from each of the checked check boxes. I really just want to populate an array with all the check boxes that are checked.
I started a simplified example here: http://jsfiddle.net/kralco626/JvAdg/1/
The actual code is more like this:
var dataList = new Array(10);
dataList[0] = "Delete";
dataList[1] = LD_LicenseNumber.val();
dataList[2] = $("#LDOperatingCompanies input:checked").val();
And aspx code:
<div id="LDOperatingCompanies">
<input type="checkbox" value="o1" id="o1" name="LDOperatingCompanies" /><label for="o1">o1</label>
<input value="o2" type="checkbox" id="o2" name="LDOperatingCompanies" /><label for="o2">o2</label>
<input value="o3" value="o1" type="checkbox" id="o3" name="LDOperatingCompanies" /><label for="o3">o3</label>
</div>
Thanks!
here is an update to your fiddle that puts all checked boxes into an array Example
HTML
<div id="LDOperatingCompanies">
<input type="checkbox" id="o1" name="LDOperatingCompanies" /><label for="o1">o1</label>
<input type="checkbox" id="o2" name="LDOperatingCompanies" /><label for="o2">o2</label>
<input type="checkbox" id="o3" name="LDOperatingCompanies" /><label for="o3">o3</label>
</div>
<input type="button" id="btn" value="alert checked boxes" />
JavaScript
var checks = [];
$('#btn').click(function(e) {
$(':checked').each(function(index, item) {
checks.push( item );
});
if(checks.length == 0) alert('nothing checked');
else alert(checks);
});
