Check only non-disabled

I have a sequence of checkboxes that can be disabled or not through the disabled in the input tag
By clicking on the parent checkbox, I need only those NOT disabled to be checked
Current and desired:
Code so far:
$("#checkAll").click(function () {
$("input:checkbox").not(this).prop("checked", this.checked);
});

You could use the :not() selector combined with the has attribute selector :
$("#checkAll").change(function () {
$("input:checkbox:not([disabled])").prop("checked", this.checked);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="checkbox" id="checkAll" />
<input type="checkbox" />
<input type="checkbox" disabled />
<input type="checkbox" />
<input type="checkbox" disabled />
<input type="checkbox" />
As suggested by #connexo, you should use .change() instead of .click(). See this answer for more information.

Vanilla JS, always preferred:
document.getElementById('checkAll').addEventListener('change', function() {
for (const cb of document.querySelectorAll('input[type=checkbox]:not([disabled])')) {
if (cb !== this) cb.checked = this.checked;
}
});
<input type="checkbox" id="checkAll" />
<input type="checkbox" />
<input type="checkbox" disabled />
<input type="checkbox" />
<input type="checkbox" disabled />
<input type="checkbox" />

How can I target unchecked checkboxes in jQuery?

When I uncheck any checkbox it also appends the result. I want to remove that. What should I do?
$(document).ready(function(){
$('.chk_val').on('click',function(){
var result = $(this).val();
$('#course').append(result);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="show">
<span id="course"> </span>
</div>
<input type="checkbox" class="chk_val" value="20" />20
<br />
<input type="checkbox" class="chk_val" value="30" />30
<br />
<input type="checkbox" class="chk_val" value="40" />40
<br />

$(document).ready(function() {
$('.chk_val').on('click', function() {
var result = $('.chk_val:checked').map(function() {
return $(this).val()
}).get();
$('#course').html(result);
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="show">
<span id="course"> </span>
</div>
<input type="checkbox" class="chk_val" value="20" />20
<br />
<input type="checkbox" class="chk_val" value="30" />30
<br />
<input type="checkbox" class="chk_val" value="40" />40
<br />
Map the value of checked items.
Use .html() to change the html of the div

Save checkbox status in one cookie

I have this code:
$("input.box[type=checkbox]").each(function() {
var name = $(this).attr('name');
if ($.cookie(name) && $.cookie(name) == "true") {
$(this).prop('checked', $.cookie(name));
}
});
$("input.box[type=checkbox]").change(function() {
var name = $(this).attr("name");
$.cookie(name, $(this).prop('checked'), {
path: '/',
expires: 365
});
});
and html:
<input type="checkbox" name="smth1" />something1<br />
<input type="checkbox" name="smth2" />something2<br />
<input type="checkbox" name="smth3" />something3<br />
<input type="checkbox" name="smth4" />something4<br />
<br />
<input type="checkbox" name="anthr1" />anotherthing1<br />
<input type="checkbox" name="anthr2" />anotherthing2<br />
<input type="checkbox" name="anthr3" />anotherthing3<br />
<input type="checkbox" name="anthr4" />anotherthing4<br />
<br />
<input type="checkbox" name="new1" />newthing1<br />
<input type="checkbox" name="new2" />newthing2<br />
<input type="checkbox" name="new3" />newthing3<br />
<input type="checkbox" name="new4" />newthing4<br />
etc etc
This makes cookie for every checkbox. What I want to do is save checkboxes status in only one cookie. I'd appreciate your help! Thanks!

jQuery radio subcategory uncheck on parent button change

I have a form that finds lost and found items.
<input type="radio" name="subcatitemlost" value="subDiv1" />Luggage
<div id="subDiv1" class="desc">
<label>
<input type="radio" name="subluggage" id="truck" value="t" />
</label>Trunk</br>
<label>
<input type="radio" name="subluggage" id="chest" value="chest" />
</label>Chest</br>
<label>
<input type="radio" name="subluggage" id="suitcase" value="suitcase" />
</label>Suitcase</br>
<label>
<input type="radio" name="subluggage" id="duffelbag" value="duffelbag" />
</label>Duffelbag</br>
<label>
<input type="radio" name="subluggage" id="tote" value="tote" />
</label>Tote</br>
</div>
<br />
<input type="radio" name="subcatitemlost" value="subDiv2" />Clothing
<div id="subDiv2" class="desc">
<input type="radio" name="subclothing" id="shirt" value="shirt" />
</label>Shirt</br>
<input type="radio" name="subclothing" id="shoes" value="shoes" />
</label>Shoes</br>
<input type="radio" name="subclothing" id="pants" value="pants" />
</label>Pants</br>
<input type="radio" name="subclothing" id="jacket" value="jacket" />
</label>Jacket</br>
<input type="radio" name="subclothing" id="suit" value="suit" />
</label>Suit</br>
<input type="radio" name="subclothing" id="hat" value="hat" />
</label>Hat</br>
</div>
<br />
The main categories will unselect themselves upon selection of another main category , however , the subcategories will remain selected and I cannot figure how to control that.I am looking for the script that doesn't allow another subcategory to be selected when the correct button is selected.
$(document).ready(function () {
$("div.desc").hide();
$("input[name$='subcatitemlost']").click(function () {
var test = $(this).val();
$("div.desc").hide();
$("#" + test).show();
});
});

Try using this
$(document).ready(function() {
$("div.desc").hide();
$("input[name$='subcatitemlost']").click(function() {
var test = $(this).val();
$("div.desc").hide();
$("#" + test).show();
$("div input:radio").attr('checked', false);
});
});

How to add value of checked checkbox to textarea using jQuery?

How can I use jQuery to delete the text in the textarea that gets from the input_one when it not checked (one_1 one_3 one_4) ,and when it checked add it into textarea again?
The code is below:
<div id="input_one">
<input type="checkbox" value="one">
<input type="checkbox" value="one_1">
<input type="checkbox" value="one_2">
<input type="checkbox" value="one_3">
<input type="checkbox" value="one_4">
</div>
<div id="input_two">
<input type="checkbox" value="two_1">
<input type="checkbox" value="two_2">
<input type="checkbox" value="two_3">
<input type="checkbox" value="two_4">
<input type="checkbox" value="two_5">
</div>
<textarea id="get_checked"></textarea>
For example textarea value should be one one_3 two_4

Hope this helps
function updateTextArea() {
var allVals = [];
$('#input_one :checked,#input_two :checked').each(function () {
allVals.push($(this).val());
});
$('#get_checked').val(allVals);
}
$(function () {
$('#input_one input,#input_two input').click(updateTextArea);
});
jsfiddle

You can select checked checkbox using :checked selector and use .map() to replace item of checkboxs array with value of it.
$("#input_one :checkbox, #input_two :checkbox").change(function() {
var text = $("#input_one :checked, #input_two :checked").map(function() {
return this.value;
}).get().join(" ");
$("#get_checked").val(text);
});
$(":checkbox").change(function() {
var text = $(":checked").map(function() {
return this.value;
}).get().join(" ");
$("#get_checked").val(text);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="input_one">
<input type="checkbox" value="one" />
<input type="checkbox" value="one_1" />
<input type="checkbox" value="one_2" />
<input type="checkbox" value="one_3" />
<input type="checkbox" value="one_4" />
</div>
<div id="input_two">
<input type="checkbox" value="two_1" />
<input type="checkbox" value="two_2" />
<input type="checkbox" value="two_3" />
<input type="checkbox" value="two_4" />
<input type="checkbox" value="two_5" />
</div>
<textarea id="get_checked"></textarea>
As you said in question, the resutl text splited by space.
