Javascript checkbox selection order - javascript

How would I go about detecting the order in which checkboxes are checked? I have a list of checkboxes on a form, and I need to have users select their first and second choices (but no more). So, given this:
<input name="checkbox1" type="checkbox" value="a1"> Option 1
<input name="checkbox1" type="checkbox" value="a2"> Option 2
<input name="checkbox1" type="checkbox" value="a3"> Option 3
<input name="checkbox1" type="checkbox" value="a4"> Option 4
If someone selects option 2, then option 3, I'd like to have some indicator that option 2 was the first choice, and option 3 was the second choice. Any ideas?
Thanks in advance.
Update:
These are extremely helpful suggestions, thank you. As I test these examples, it's giving me a better idea of how to approach the problem - but I'm still a bit stuck (I'm a JS novice). What I want to do is have these labels change as the checkboxes are checked or unchecked, to indicate which is the first or second selection:
<label id="lblA1"></label><input name="checkbox1" type="checkbox" value="a1"> Option 1
<label id="lblA2"></label><input name="checkbox1" type="checkbox" value="a2"> Option 2
<label id="lblA3"></label><input name="checkbox1" type="checkbox" value="a3"> Option 3
<label id="lblA4"></label><input name="checkbox1" type="checkbox" value="a4"> Option 4
So if someone clicks Option 2, then Option 3, lblA2 will display "First", and lblA3 will display "Second". If someone unchecks Option 2 while Option 3 is still checked, lblA3 becomes "First". Hopefully this makes sense?
Thanks!

If you are using jQuery. Below code is does what you have explained and it is tested.
I have used global variables.
<input name="checkbox1" type="checkbox" value="a1" /> Option 1
<input name="checkbox1" type="checkbox" value="a2" /> Option 2
<input name="checkbox1" type="checkbox" value="a3" /> Option 3
<input name="checkbox1" type="checkbox" value="a4" /> Option 4
<input type="button" value="do" id="btn" />
As shown below, it also handles the situation that user unchecks a choice.
$(document).ready(function () {
var first = "";
var second = "";
$('input[name="checkbox1"]').change(function () {
if ($(this).attr('checked')) {
if (first == "") {
first = $(this).attr('value');
}
else if (second == "") {
second = $(this).attr('value');
}
}
else {
if (second == $(this).attr('value')) {
second = "";
}
else if (first == $(this).attr('value')) {
first = second;
second = "";
}
}
});
$('#btn').click(function () {
alert(first);
alert(second);
});
});
I hope that it will be helpful.
UPDATE [IMPORTANT]:
I have noticed that my previous code was incomplete, for example, if you check a1, then a2, then a3, then uncheck a2; my code was not recognising a3 as second.
Here is the complete solution of your updated problem. I used array this time.
The complete HTML:
<label id="lblA1"></label>
<input name="checkbox1" type="checkbox" value="a1" /> Option 1
<label id="lblA2"></label>
<input name="checkbox1" type="checkbox" value="a2" /> Option 2
<label id="lblA3"></label>
<input name="checkbox1" type="checkbox" value="a3" /> Option 3
<label id="lblA4"></label>
<input name="checkbox1" type="checkbox" value="a4" /> Option 4
The complete Javascript:
$(document).ready(function () {
var array = [];
$('input[name="checkbox1"]').click(function () {
if ($(this).attr('checked')) {
// Add the new element if checked:
array.push($(this).attr('value'));
}
else {
// Remove the element if unchecked:
for (var i = 0; i < array.length; i++) {
if (array[i] == $(this).attr('value')) {
array.splice(i, 1);
}
}
}
// Clear all labels:
$("label").each(function (i, elem) {
$(elem).html("");
});
// Check the array and update labels.
for (var i = 0; i < array.length; i++) {
if (i == 0) {
$("#lbl" + array[i].toUpperCase()).html("first");
}
if (i == 1) {
$("#lbl" + array[i].toUpperCase()).html("second");
}
}
});
});

have 2 javascript variables first and second. whenever a checkbox is checked check if first is null if so assign the checkbox id to it, if first is not null set second.

You could have a change listener and a hidden field. Every time the user selects a checkbox, you add the value. Like so (assuming #parent is the parent element of the boxes):
$('#parent').delegate('input[type=checkbox]', 'change', function() {
if($(this).is(':checked')) {
$('#hidden').val($('#hidden').val() + " " + $(this).val())
}
});
The value of the hidden field would then be something like a2 a3 a1...
This is if you want to process the information at the server side. You can then split the string at the server side and examine it. Of course you have to handle removal and adding of selections.
If you just want to process the values on the client, you can add it to an array:
var selected = [];
$('#parent').delegate('input[type=checkbox]', 'change', function() {
if($(this).is(':checked')) {
selected.push($(this).val());
}
});

Try -
$(document).ready(function(){
var checked_no = 0;
$('input[name="checkbox1"]').change(function(){
alert($('input[name="checkbox1"]').filter(':checked').length);
checked_no = $('input[name="checkbox1"]').filter(':checked').length;
// checked_no acts as a counter for no of checkboxes checked.
});
});

Here you have it, if you want something more sophisticated (e.g. to test when an option is unclicked) you have to do some extra work. Just test this html in your browser:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>
<script type = "text/javascript">
var checkboxClicks = new Array(2);
function updateClickOrder(checkbox) {
if (checkbox.checked) {
if (checkboxClicks[0] ==null) {
checkboxClicks[0] = checkbox.value;
} else if (checkboxClicks[1] ==null) {
checkboxClicks[1] = checkbox.value;
}
}
document.forms[0].clickOrder.value = checkboxClicks[0] + ", " + checkboxClicks[1];
alert(document.forms[0].clickOrder.value);
//alert("Clicked " + checkbox.value);
}
</script>
</head>
<body>
<form name="testCheckboxClickOrder">
<input name="checkbox1" type="checkbox" value="a1" onchange="updateClickOrder(this);"> Option 1
<input name="checkbox1" type="checkbox" value="a2" onchange="updateClickOrder(this);"> Option 2
<input name="checkbox1" type="checkbox" value="a3" onchange="updateClickOrder(this);"> Option 3
<input name="checkbox1" type="checkbox" value="a4" onchange="updateClickOrder(this);"> Option 4
<input type="hidden" name="clickOrder"/>
</form>
</body>
</html>

This is going to save the order in an array. If you deselect the position is removed. The script will attempt to find the element by its value and remove. If you select again the value is added.
<input type="checkbox" value="v1" />
<input type="checkbox" value="v2" />
<input type="checkbox" value="v3" />
<input type="checkbox" value="v4" />

{

++c;
}
else
{
var i = parseInt(userInput.join().indexOf($(this).val())) - 2;
userInput.splice(i, 1);
}
});
$("textarea").click(function()
{
$(this).val("");
for (var i in userInput)
{

Check at most four check box and store checked value to textbox

I am displaying some check boxes. The user can check a maximum of 4 boxes. I store the checked value in 4 textboxes.
My problem: How can I correctly store the "new" checked value when the user randomly unchecks one box and checks another?
I store values as follows: First checked into item_1, second checked into item_2, third checked into item_3 ... If the user unchecks the first checked box, for example, how can I store the value of the next box he or she checks into item_1? Please help.
Simplified code
<input type="checkbox" name="prodname_1" id="prodname_1"value="1"/>
<input type="checkbox" name="prodname_2" id="prodname_2"value="2"/>
<input type="checkbox" name="prodname_3" id="prodname_3"value="3"/>
.
.
<input type="checkbox" name="prodname_10" id="prodname_10"value="10"/>
<input type="text" name="item_0" id="item_0"value=""/>
<input type="text" name="item_1" id="item_1"value=""/>
<input type="text" name="item_2" id="item_2"value=""/>
<input type="text" name="item_3" id="item_3"value=""/>
$(document).ready(function (e)
{
counter=0;
$('input[id^="prodname_"]').change(function()
{
id = $(this).attr('id');
var arr = id.split('_');
valueChecked=$('#'+id).val();
if(this.checked)
{
if(counter==4)
{
alert('Allready checked 4 items');
this.checked=false;
return false;
}
$("#item_"+counter).val(valueChecked);
++counter;
}
});
});
Instead of retaining a counter, just count the number of checked boxes when the change occurs.
Revised to use the logic you intended (took a little while to figure that out) :)
JSFiddle: http://jsfiddle.net/TrueBlueAussie/tmLnbvv0/9/
$(document).ready(function (e) {
var $items = $('input[id^="item_"]');
var checkboxes = $('input[id ^= "prodname_"]').change(function () {
var id = $(this).attr('id');
var arr = id.split('_');
valueChecked = $(this).val();
// Count of checked checkboxes
var counter = checkboxes.filter(':checked').length;
if ($(this).is(':checked')) {
// count the checked checkboxes
if (counter > 4) {
alert('Already checked 4 items');
$(this).prop('checked', false);
} else {
// Add to the first available slot
$items.filter(function(){return $(this).val() == ""}).first().val(valueChecked);
}
} else {
// Remove the matching value
$items.filter(function(){return $(this).val() == valueChecked;}).first().val('');
}
});
});
note: The "jQuery way" for changing checkboxes is to use prop('checked', booleanvalue) (also changed above)
V2 - If you don't want gaps:
This version is actually simpler as it just clears the items and fills them, in order, with any checked checkbox values.
JSFiddle: http://jsfiddle.net/TrueBlueAussie/tmLnbvv0/13/
$(document).ready(function (e) {
var $items = $('input[id^="item_"]');
var $checkboxes = $('input[id ^= "prodname_"]').change(function () {
// Count of checked checkboxes
var counter = $checkboxes.filter(':checked').length;
// count the checked checkboxes
if (counter > 4) {
alert('Already checked 4 items');
$(this).prop('checked', false);
}
// Clear all the items
$items.val('');
// Fill the items with the selected values
var item = 0;
$checkboxes.filter(':checked').each(function () {
$('#item_' + (item++)).val($(this).val());
});
});
});
Look at
$(document).ready(function(e) {
var counter = 0,
$items = $('input[name^="item_"]');
$('input[id^="prodname_"]').change(function() {
var id = this;
if (this.checked) {
if (counter == 4) {
this.checked = false;
return;
}
$("#item_" + counter).val(this.value).attr('data-value', this.value);
++counter;
} else {
var $item = $items.filter('[data-value="' + this.value + '"]');
var index = $items.index($item);
$items.slice(index, counter).each(function(i) {
var $n = $items.eq(index + i + 1);
$(this).val($n.val() || '').attr('data-value', $n.attr('data-value'));
});
counter--;
$("#item_" + counter).val('').removeAttr('data-value');
}
});
});

Limit checkbox based on value JavaScript

I'm trying to create a checkbox limit based on a value change example:
I have the following checkbox
<input type="checkbox" name="checkbox2[]" onClick="setChecks(this)" value="`key`=<?php
echo $rspatient['key']?>" class="chk" id="chk<?php echo $a++?>" />
I have a lot of check box as this is in a loop. Some have the same value others do not. Anyways wanting to create code that prevents checking boxes with different values!
Current code for limiting checkbox number:
<script>
<!--
//initial checkCount of zero
var checkCount = 0
//maximum number of allowed checked boxes
var maxChecks = 3
var d = document.getElementById('chk' + (j++));
function setChecks(obj) {
//increment/decrement checkCount
if (obj.checked) {
checkCount = checkCount + 1
} else {
checkCount = checkCount - 1
}
//if they checked a 4th box, uncheck the box, then decrement checkcount and pop alert
if (checkCount > maxChecks) {
obj.checked = false
checkCount = checkCount - 1
alert('you may only choose up to ' + maxChecks + ' options')
}
}
// -->
</script>
I tried to edit the final if statement with no luck!
After some messing around i managed to end up with this a working solution!
1 <input type="checkbox" value="1" /><br/>
2 <input type="checkbox" value="2" /><br/>
3 <input type="checkbox" value="3" /><br/>
1 <input type="checkbox" value="1" /><br/>
2 <input type="checkbox" value="2" /><br/>
3 <input type="checkbox" value="3" /><br/>
1 <input type="checkbox" value="1" /><br/>
2 <input type="checkbox" value="2" /><br/>
3 <input type="checkbox" value="3" /><br/>
$(function() {
var lastChecked = [];
$(':checkbox').change(function() {
if (this.checked) {
if (lastChecked.length && this.value != lastChecked[0].value) {
this.checked = false;
alert("the last box you checked has a different value");
}
else
{
lastChecked.unshift(this);
}
}
else {
lastChecked.splice(lastChecked.indexOf(this), 1);
}
});
});​
​
lastChecked.splice(lastChecked.indexOf(this), 1);
}
});
});​

Checkbox and text field, if one is selected or has value require other(s)

I have two checkboxes in a group and one text input. If one (or both) of the checkboxes are selected I need to have the text input be required, as well as if the text input has text I need at least one of the checkboxes to be required. Another problem I'm having it that it's using a custom templating engine (PHP backend) and is a pain to configure and get the attributes correct, another issue is it's all referenced by the name attribute and this is why I'm using a HTML5 data-group for the checkbox options which I think it working.
Any help in getting this to work, combining functions (if this makes it easier/simpler).
BTW it's running 1.3.2 jQuery
Example: (not working)
http://jsfiddle.net/NYn8e/1/
Any suggestions?
JS:
function checkboxSelectedRequiredAdditionalFields(elem) {
var passedElement = $('input:checkbox[name=' + elem + ']');
passedElement.click(function() {
$('input[name=number]').attr('required', true).append('<span class="required">*</span>');
alert('text is required now?');
});
}
function numberEnteredRequiredAdditionalFields(elem) {
var passedElement = $('input[name=' + elem + ']');
if (passedElement.val().length > 0) {
var boxes = $('input[data-group=cbOptions]').click(function() {
boxes.not(this).attr('required', false);
alert('checkbox is selected so other checkbox is not required');
});
$('input[data-group=cbOptions]').each(function() {
$(this).attr('required', true).next().append('<span class="required">*</span>');
alert('checkbox is required now?');
});
}
}
HTML
<form>
<label>
<input type="checkbox" name="checkbox1" value="t" onclick="checkboxSelectedRequiredAdditionalFields('checkbox1');" data-group="cbOptions">
Checkbox Option 1
</label>
<label>
<input type="checkbox" name="checkbox2" value="t" onclick="checkboxSelectedRequiredAdditionalFields('checkbox2');" data-group="cbOptions">
Checkbox Option 2
</label>
Number <b>
<input type="text" name="number" value="" size="" maxlength="9" onclick="numberEnteredRequiredAdditionalFields('number');">
</b>
</form>
You should separate the JavaScript from the HTML. Fiddle: http://jsfiddle.net/NYn8e/6/. If possible, remove <b> from the HTML source, and extend the style sheet with the right CSS property: font-weight: bold;.
<form>
<label>
<input type="checkbox" name="checkbox1" value="t" data-required="checkbox">
Checkbox Option 1
</label>
<label>
<input type="checkbox" name="checkbox2" value="t" data-required="checkbox">
Checkbox Option 2
</label>
Number <b>
<input type="text" name="number" value="" size="" maxlength="9" data-required="number">
</b>
</form>
JavaScript:
function required(){
//Any checked checkbox? checked == 0 = no, otherwise: yes
var checked = $('input[data-required=checkbox]:checked').length;
var $checkboxes = $('input[data-required=checkbox]');
var $num = $('input[name=number]');
var length = $num.val().length;
//Remove previously added span, if existent.
$num.next('span.required').remove();
$checkboxes.next('span.required').remove();
if(!length && checked){
$num.after('<span class="required">*</span>');
alert("Number required!");
} else if(length && !checked){
$checkboxes.after('<span class="required">*</span>');
alert("Check at least one checkbox.");
}
}
$(document).ready(function(){
$("[data-required]").change(required);
});
=) Would this one help you?
<form id='myForm'>
<input type='checkbox' name='checkbox1' value='t' id='checkbox1' onchange='alertUser()' />
<input type='checkbox' name='checkbox2' value='t' id='checkbox2' onchange='alertUser()' />
<input type='text' name='number' id='number' onchange='alertUser()'/>
</form>
<script type='text/javascrip>
function alertUser() {
var checked1 = $('#checkbox1').attr('checked');
var checked2 = $('#checkbox2').attr('checked');
var number = $('#number').val();
if ((checked1 == true || checked2 == true) && number == '') {
alert('Number is required!');
} else if (number != '' && (checked1 != true && checked2 != true)) {
alert('One of the checkbox need to be checked!');
}
});
</script>
This should hopefully give you an idea on how to accomplish the task. http://jsfiddle.net/NYn8e/8/
var $textbox = $('input[name=number]').hide();
$('input[type=checkbox]').change(function() {
var $this = $(this); //store jquery object
//get the other checkbox
var $other= ($this.attr('name') === 'checkbox1') ? $('input[name=checkbox2]') : $('input[name=checkbox1]');
if (!$other.is(':checked') && !$this.is(':checked')) {
$textbox.val('').hide();
} else{
$textbox.show();
}
});

Adding form verification in this case

I've got 3 groups of radio buttons and 1 set of check boxes.
How do i check if a radio button is selected in each group of radio buttons and at least one check box is selected? And if not, maybe pop an alert window.
So thats : one radio button needs to be selected from all three groups and one check box (all four are mandatory). I've had no luck with this. Thanks

Here's a modified version of your function:
function DisplayFormValues() {
var str = '';
var elem = document.getElementById('frmMain').elements;
var groups = { 'r1': 0, 'r2': 0, 'r3':0, 'c1': 0 };
for (var i = 0; i < elem.length; i++){
if (elem[i].checked) {
var n = elem[i].name;
groups[n] += 1
str += elem[i].value + "<br>";
}
}
document.getElementById('lblValues').innerHTML = groups['r1'] + "/" +
groups['r2'] + "/" + groups['r3'] + "/" + groups['c1'];
document.frmMain.reset();
}
In this function we count how many elements are checked (obviously one for radio button in the same group but you understand the principle and this is flexible) and groups[XXX] is the count (with XXX being the group name).
You can adjust to your needs and add the alert as requested.
You can do this in javascript by writing a lot of code or I strongly recommend using jquery validation plugin. Look at this example: http://jquery.bassistance.de/validate/demo/radio-checkbox-select-demo.html
You can do something like:
<input type="radio" validate="required:true" name="family" value="s" id="family_single" class="error">
Which will require at least one option being selected.
Also, its best to have inline feedback when something is not valid. Having alerts can be really annoying.
var radioCount = 0;
var checkBoxCount = 0;
var currentElement;
for (var i = 0; i < elem.length; ++i) {
currentElement = elem[i];
if (!currentElement.checked)
continue;
if (currentElement.type == "checkbox")
++checkBoxCount;
else if (currentElement.type == "radio")
++radioCount;
}
if (radioCount < 3)
//fail
if (checkBoxCount < 1)
//fail

if(o1.checked) {
//Remove o2 children
}
else if(o2.checked) {
//How do I add an input box?
}
}
<input type="radio" id="dateoption1" name="dateoption" value="1" onclick="CheckDateOptions();">
<input type="radio" id="dateoption2" name="dateoption" value="2" onclick="CheckDateOptions();">
<span id="datesettings">//Add input box here if dateoption2 is checked</span>
The simplest route would be:
<input type="radio" id="dateoption1" name="dateoption" value="1" ="ToggleDateOptions(true);" />
<input type="radio" id="dateoption2" name="dateoption" value="2" ="ToggleDateOptions(false);" />
<span id="datesettings">
<input type="text" id="dateSetting" />
</span>
<script>
function ToggleDateOptions(oneChecked) {
if(oneChecked)
{
$("#dateSetting").hide();
}
else
{
$("#dateSetting").show();
}
}
</script>
Or if you didn't want to use JQuery (Which is used above) you could do:
if(oneChecked)
{
document.getElementById("dateSetting").style.display = 'none';
}
else
{
document.getElementById("dateSetting").style.display = 'inline';
}
You can just use innerHTML to add the input field.
Something like this should work for you
<script type="text/javascript">
function CheckDateOptions() {
var o1 = document.getElementById("dateoption1");
var o2 = document.getElementById("dateoption2");
var eSettings = document.getElementById("datesettings");
if(o1.checked) {
eSettings.innerHTML = "";
} else if(o2.checked) {
eSettings.innerHTML = '<input type="text" name="field" />';
}
}
</script>
<input type="radio" id="dateoption1" name="dateoption" value="1" onclick="CheckDateOptions()"/>
<input type="radio" id="dateoption2" name="dateoption" value="2" onclick="CheckDateOptions()"/>
<span id="datesettings"></span>
