A variable, Multiple Checkbox Select/Deselect using jQuery

I found this code to make something have multiple checkbox select/deselect. The code itself works fine but I want it be able to take in a variable so I do not need to write it 20 times in my script.
What it looks like now:
$(function(){
// add multiple select / deselect functionality
$("#selectcase").click(function () {
$('.case').attr('checked', this.checked);
});
// if all checkbox are selected, check the selectall checkbox
// and viceversa
$(".case").click(function(){
if($(".case").length == $(".case:checked").length) {
$("#selectcase").attr("checked", "checked");
} else {
$("#selectcase").removeAttr("checked");
}
});
What I want to take in:
function locatebox(x){
console.log(x);
// add multiple select / deselect functionality
$("#select" + x).click(function(x) {
$("." + x ).attr("checked", this.checked);
});
// if all checkbox are selected, check the selectall checkbox
// and viceversa
$("." + x ).click(function(x){
if($("." + x).length == $("." + x + ":checked").length) {
$("#select" + x ).attr("checked", "checked");
} else {
$("#select" + x).removeAttr("checked");
}
});
//locatebox("rase");
}
locatebox("rase");
When I look in the executed code It shows that rase function has been generated but it does not check any boxes.
Thank you to anyone that could possibly help me out.
Edit: I for got to show how I call it and what the check-box values will be.
I do not know if this is the correct to call out the JavaScript.
Call the multi-select check-box:
<td><input type="checkbox" id="selectrase" onclick="locatebox('rase');"/></td>
Defining one check box:
<td align="center"><input type="checkbox" class="rase" name="rase" value="3"/></td>
<td align="center"><input type="checkbox" class="rase" name="rase" value="4"/></td>
Thank you once again.

I think your architecture for this is just fundamentally flawed. Using onclick() and jQuery makes for insanely hard debugging. With jQuery you should be using prop(). Take advantage of classes and the data attribute to target other elements.
Instead consider:
// Wait for the document to load
$(document).ready(function(){
// for all elements that have this class watch for clicks
$('.js-checkbox-group-toggle').on('click', function(){
// create jquery object of what was clicked
var $this = $(this);
// find the selector target for what was clicked;
var target = $this.data('group-target');
// find all the selector targets
var $targets = $(target);
// assign all the targets the value of what was clicked
$targets.prop("checked", $this.prop("checked"));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" class="js-checkbox-group-toggle" data-group-target=".group1" />Targets Group 1<br />
<input type="checkbox" class="js-checkbox-group-toggle" data-group-target=".group2" />Targets Group 2<br />
<input type="checkbox" class="group1" />Hello 1<br />
<input type="checkbox" class="group2" />Hello 2<br />
<input type="checkbox" class="group1" />Test 1<br />
<input type="checkbox" class="group2" />Test 2<br />
<input type="checkbox" class="group2" />English 2<br />
<input type="checkbox" class="group1" />Breakfast 1<br />
Add as MANY of these as you want, you have no variables in JS to mess with and the code base never has to change.

<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<td><input type="checkbox" id="selectrase" /></td>
<td align="center"><input type="checkbox" class="rase" name="rase" value="3"/></td>
<td align="center"><input type="checkbox" class="rase" name="rase" value="4"/></td>
...
<script type="text/javascript"><!--
function locatebox(x){
console.log(x);
// add multiple select / deselect functionality
var id = "#select" + x;
var className = '.' + x;
$(id).click(function(x) {
$(className).prop("checked", $(id).is(':checked'));
});
// if all checkbox are selected, check the selectall checkbox
// and viceversa
$(className).click(function(){
$(id).prop("checked", ($(className).length == $(className + ":checked").length));
});
}
$(document).ready(function(){
locatebox("rase");
}) ;
//--></script>

Checkbox dependencies in jquery

I'm trying to implement dependencies between various checkboxes, however, I've a simple scenario that if and checkbox is unchecked, other checkboxes should also be unchecked in ascending order.
Let the first checkbox has id=1, and I've total 5 checkboxes, if the first checkbox is unchecked, other check boxes that have id's greater than the current should also be unchecked, i.e. id=2, id=3, id=4, id=5 should also be unchecked and so on.
My Code:
<input type="checkbox" id="1" class="cb">
<input type="checkbox" id="2" class="cb">
<input type="checkbox" id="3" class="cb">
<input type="checkbox" id="4" class="cb">
<input type="checkbox" id="5" class="cb">
$('input.CB').on('change', function() {
$('input.CB').not(this).prop('checked', false);
});

If i understood your question correctly you're looking for something like this:
lowest_unchecked = false;
$('.cb').on('change', function(){
$('.cb').each(function(){
if( !$(this).prop( 'checked' ) ){
lowest_unchecked = $(this).attr('id');
}
if( lowest_unchecked !== false && lowest_unchecked < $(this).attr('id') ){
$(this).prop('checked', false);
}
});
});
it could be made more efficient by not making it check id's smaller then the one that a change occurs at, but this will probably do just fine for your needs.

jQuery - checkboxes selecting all on a row or with similar names & ID's

Using jQuery 1.9.1 & getting XML returned from a query that needs to be displayed in a web page as shown in the picture below. I had asked a similar question several days ago but was all over the place in what I was asking. Hope to ask better questions this time.
For the items in the picture, the XML input would be:
<Classrooms>
<Room Number="3">
<Machine>310</Machine>
<Machine>320</Machine>
<Machine>340</Machine>
<Machine>350</Machine>
</Room>
<Room Number="8">
<Machine>810</Machine>
<Machine>820</Machine>
<Machine>840</Machine>
</Room>
<Room Number="10">
<Machine>1010</Machine>
<Machine>1020</Machine>
</Room>
</Classrooms>
The code below is a function that is called upon a successful AJAX GET and builds the checkboxes in a table on the web page.
var $roomList = $( items );
var roomListString = jQ_xmlDocToString( $roomList );
var roomListXML = $.parseXML(roomListString);
$(roomListXML).find("Row").each(function() {
var activeRooms = $( roomListXML ).find("Row").text();
var nbrRooms = $(activeRooms).find("Room").size();
$(activeRooms).find("Room").each(function() {
var roomNo = $(this).attr("Number");
var roomchk = "Room"+roomNo;
var $tr = $("<tr />");
$tr.append('<td><input type="checkbox" name="'+roomchk+'" id="'+roomchk+'" class="checkall" /><label for="'+roomchk+'">Room '+roomNo+'</td>');
$("#mytable").append( $tr );
$(this).children().each(function() {
var machID = $(this).text();
var idname = "Room"+roomNo+"Mach"+machID;
$tr.append('<td><input type="checkbox" name="'+idname+'" id="'+idname+'" /><label for="'+idname+'">'+machID+'</td>');
$("#mytable").append( $tr );
});
});
});
When the above code is run on the data, the HTML in the table is as shown below.
<tbody>
<tr>
<td>
<input name="Room3" id="Room3" class="checkall" type="checkbox" />
<label for="Room3">Room 3</label>
</td>
<td>
<input name="Room3Mach310" id="Room3Mach310" type="checkbox" />
<label for="Room3Mach310">310</label>
</td>
<td>
<input name="Room3Mach320" id="Room3Mach320" type="checkbox" />
<label for="Room3Mach320">320</label>
</td>
<td>
<input name="Room3Mach340" id="Room3Mach340" type="checkbox" />
<label for="Room3Mach340">340</label>
</td>
<td>
<input name="Room3Mach350" id="Room3Mach350" type="checkbox" />
<label for="Room3Mach350">350</label>
</td>
</tr>
<tr>
<td>
<input name="Room8" id="Room8" class="checkall" type="checkbox" />
<label for="Room8">Room 8</label>
</td>
<td>
<input name="Room8Mach810" id="Room8Mach810" type="checkbox" />
<label for="Room8Mach810">810</label>
</td>
<td>
<input name="Room8Mach820" id="Room8Mach820" type="checkbox" />
<label for="Room8Mach820">820</label>
</td>
<td>
<input name="Room8Mach840" id="Room8Mach840" type="checkbox" />
<label for="Room8Mach840">840</label>
</td>
</tr>
<tr>
<td>
<input name="Room10" id="Room10" class="checkall" type="checkbox" />
<label for="Room10">Room 10</label>
</td>
<td>
<input name="Room10Mach1010" id="Room10Mach1010" type="checkbox" />
<label for="Room10Mach1010">1010</label>
</td>
<td>
<input name="Room10Mach1020" id="Room10Mach1020" type="checkbox" />
<label for="Room10Mach1020">1020</label>
</td>
</tr>

Selection of any checkbox on the page will enable a SUBMIT button on the page, which when clicked will pass the value of the boxes checked into another function. The user can select any number of the individual boxes (the ones with the number beside them), regardless of the room those items are associated with. When the user selects a Room checkbox though, ALL the individual checkboxes for that room should also be checked. The individual values are the ones I want. When the SUBMIT button is clicked, the individual values are all that will be sent to that function.
I had looked at this topic about using a checkbox class to select all.
I'm using the code below to find what's checked. I can see when I select an individual box that it gets added to the array. I can also see when I select a Room that the checkall is found, but I can't seem to make the individual checkboxes get checked once I do. I had been attempting to use the Attribute Starts With jQuery selector, but haven't been able to get it to check the boxes.
$("#mytable").click(function(e) {
var ele = $(this).find(":checkbox");
var zall = $(this).find(":checkbox.checkall:checked");
if (zall) {
var zname = $(zall).attr("name");
var selectallmachines = "input[name^='" + zname +"']:checked:enabled";
$( $(selectallmachines), "#mytable");
}
var arr = [];
$(":checkbox:checked").each(function(i) {
arr[i] = $(this).val();
});
});
I'm sure that it is something that I'm overlooking, but what am I missing? Would appreciate any suggestions or guidance on what I'm doing wrong, or if there's perhaps a better way to do what I'm doing.
Thanks!

You can do something like this
$('.checkall').change(function(){
$('input[id^='+this.id+']').prop('checked',this.checked);
});
when .checkall is clicked/changes - set checked property on all inputs with an id that starts with the current clicked elements id
FIDDLE
Though you probably should delegate since you are using ajax to get the elements - this is assuming #mytable exists on DOM Ready - or replace with an ancestor element that does
$('#mytable').on('click','.checkall',function(){
$('input[id^='+this.id+']').prop('checked',this.checked);
});
another alternative is to give the checkall id as a class to the relative checkboxes
$tr.append('<td><input type="checkbox" name="'+idname+'" id="'+idname+'" class="'+roomchk+'"/><label for="'+idname+'">'+machID+'</td>');
then you can do
$('#mytable').on('click','.checkall',function(){
$('input.'+this.id).prop('checked',this.checked);
});
FIDDLE

CheckAll/UncheckAll checkbox with jQuery

I have made a check-box checkall/uncheckall.
HTML
<div> Using Check all function </div>
<div id="selectCheckBox">
<input type="checkbox" class="all" onchange="checkAll('selectCheckBox','all','check','true');" />Select All
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 1
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 2
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 3
<input type="checkbox" class="check" onchange="checkAll('selectCheckBox','all','check','false');" />Check Box 4
</div>
main.js
function checkAll(parentId,allClass,checkboxClass,allChecked){
checkboxAll = $('#'+parentId+' .'+allClass);
otherCheckBox = $('#'+parentId+' .'+checkboxClass);
checkedCheckBox = otherCheckBox.filter($('input[type=checkbox]:checked'));
if(allChecked=='false'){
if(otherCheckBox.size()==checkedCheckBox.size()){
checkboxAll.attr('checked',true);
}else{
checkboxAll.attr('checked',false);
}
}else{
if(checkboxAll.attr('checked')){
otherCheckBox.attr('checked',true);
}else{
otherCheckBox.attr('checked',false);
}
}
}
It works fine. But get bulky when I have whole lot of checkboxes. I want to do same work by using jQuery rather than putting onchange on each checkbox. I tried different sort of things but couldnot work. I tried following one:
$('.check input[type="checkbox"]').change(function(e){
checkAll('selectCheckBox','all','check','true');
});
to do same work as onchange event but didnot work. Where do I went wrong.

I think you just need this: You do not need to pass all the arguments and have the inline onchange event attached to it. You can simplify your code.
$(function () {
$('input[type="checkbox"]').change(function (e) {
if(this.className == 'all')
{
$('.check').prop('checked', this.checked); //Toggle all checkboxes based on `.all` check box check status
}
else
{
$('.all').prop('checked', $('.check:checked').length == $('.check').length); // toggle all check box based on whether all others are checked or not.
}
});
});
Demo

Your selector is wrong:
.check input[type="checkbox"]
Above selects any input of type checkbox that has the ancestor with class .check. It'll match this:
<div class="check">
<input type="checkbox".../>
</div>
it should be:
input.check[type="checkbox"]

You closed the string here $('.check input[type='checkbox']') instead, you should use double quotes $('.check input[type="checkbox"]')

Multiple checkbox value will show in textbox

Here is my code :
<body>
<div align="center">
<b>A<input type="checkbox" name="a" id="check" value="a"></b>
<b>B<input type="checkbox" name="b" id="check" value="a"></b>
<b>B<input type="checkbox" name="c" id="check" value="c"></b>
<b>D<input type="checkbox" name="d" id="check" value="d"></b>
</div>
<table align="center">
<tr>
<td>Text:</td>
<td><input type="text" name="text" id="text"></td>
</tr>
</table>
</body>
I'm trying that: if (more than one) checkbox is selected (or checked) that value will be assigned into the checkbox like "abcd" or "acd" or "bd".For that I have written jQuery
<script type="text/javascript">
$(document).click(function(){
if($("#check").attr('checked')){
$("#text").val(("#check").val());
}
});
</script>
able to print one txtbox value at a time,but not able to put all checked value in the textbox at a time.
Where I am going wrong ??Any inputs will appreciated.

I may have not understood you correctly, but does this fiddle help you? http://jsfiddle.net/XwGJ9/1/
The change is the javascript:
var $textInput = $('#text');
var $checkBox = $('#checkboxes');
$('input').click(function(){
populateTextInput();
});
function populateTextInput () {
// empty text input
$textInput.val('');
// print out all checked inputs
$checkBox.find('input:checked').each(function() {
$textInput.val( $textInput.val() + $(this).val() );
});
}
Edit: updated

Use this code
$('.check').click(function(){
$("#text").val('');
$(".check").each(function(){
if($(this).prop('checked')){
$("#text").val($("#text").val()+$(this).val());
}
});
});​
​
With this HTML (use class instead of id for abcd)
<div align="center">
<b>A<input type="checkbox" name="a" class="check" value="a"></b>
<b>B<input type="checkbox" name="b" class="check" value="b"></b>
<b>B<input type="checkbox" name="c" class="check" value="c"></b>
<b>D<input type="checkbox" name="d" class="check" value="d"></b>
</div>
<table align="center">
<tr>
<td>Text:</td>
<td><input type="text" name="text" id="text"></td>
</tr>
</table>​
Also I encourage to use CSS instead of align="center"
See live, running demo

So I think you're wanting to append the values together in the textbox. In that case, do:
<script type="text/javascript">
$(document).click(function(){
if($("#check").attr('checked')){
var textBoxVal = $("#text").val()+$("#check").val(); // Concatenate the existing textbox value with the checkbox value.
// Load the resulting value into new var textBoxVal.
$("#text").val(textBoxVal); // Load the new value into the textbox.
}
});
</script>
I used native JS just to make it clearer what I'm doing.

had used something like this.. might help you
var checkeditems = $('input:checkbox[name="check[]"]:checked')
.map(function() {
return $(this).val()
})
.get()
.join(",");
$("#text").val(checkeditems);

If you just want no multiples of a,b,c,d at one time, the onclick is per checkbox
var boxes = $("input:checkbox");
boxes.each(function(idx,elem){
elem.onclick=function(event){
var choices = "";
boxes.each(function(idx,elem){
choices += elem.checked ? elem.name:"";
});
$('#text').val(choices);
}
});
