jQuery select all inputs under ul li - javascript

How can I select all input checkboxes in li under a specific ul?
I have:
<ul id="something">
<li>
<input type="checkbox">
</li>
<li>
<input type="checkbox">
</li>
...
</ul>
Thanks


You can use $('ul li input[type=checkbox]')
Here is a working example, you can see that the console.log will show only input's a, b, d (because c's type is not checkbox).
checkboxes = $('ul li input[type=checkbox]')
checkboxes.each(function(e) {
console.log($(this).attr('name'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="something">
<li>
<input name="a" type="checkbox">
</li>
<li>
<input name="b" type="checkbox">
</li>
<li>
<input name="c" type="text">
</li>
<li>
<input name="d" type="checkbox">
</li>
</ul>


You should be able to use the ID selector for your UL like this:
var checkboxes = $("#something li input[type=checkbox]");
checkboxes.each(function(e) {
console.log($(this).attr('name'));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="something">
<li>
<input name="a" type="checkbox">
</li>
<li>
<input name="b" type="checkbox">
</li>
<li>
<input name="c" type="text">
</li>
<li>
<input name="d" type="checkbox">
</li>
</ul>
<ul id="not-these">
<li>
<input name="a-no" type="checkbox">
</li>
<li>
<input name="b-no" type="checkbox">
</li>
<li>
<input name="c-no" type="text">
</li>
<li>
<input name="d-no" type="checkbox">
</li>
</ul>


This code will let you get all the input's html
jQuery(document).ready(function()
{
jQuery( "ul#something li" ).each(function( index ) {
var html = jQuery(this).find('input[type=checkbox]').html();
console.log(html);
});
});

How to toggle selected or clicked element not all

Am trying to toggle only clicked element and adding some class to it but it's applying to all.
How can i do that?.any suggestion would be helpful.thank you
$("li").click(function(e){
$(".checkbox span").toggleClass("checked");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<li>
Wordz
<label class="checkbox">
<input type="checkbox" />
<span class="secondary"></span>
</label>
</li>
<li>
Phraser
<label class="checkbox">
<input type="checkbox" />
<span class="secondary"></span>
</label>
</li>

You can use $(this) to get current li clicked and depending on that add your class.
Demo Code:
$("li").click(function(e) {
//cuurent li->span->addclass
$(this).find('span').toggleClass("checked");
});
.checked {
color: red;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li> Wordz
<label class="checkbox">
<input type="checkbox" />
<span class="secondary">Something</span>
</label>
</li>
<li>
Phraser
<label class="checkbox">
<input type="checkbox" />
<span class="secondary">Something</span>
</label>
</li>
</ul>

select checkbox on input textbox by jquery

This is javascript:
$('.chkbx').click(function(){
var text = "";
$('.chkbx:checked').each(function(){
text += $(this).val()+',';
});
text = text.substring(0,text.length-1);
$('#textbx').val(text);
});
When I select numbers in the checkbox, It does not work in the input textbox.
JSFiddle

You can use .change event instead of .click like below,
$('.chkbx').change(function() {
// this will contain a reference to the checkbox
var text = "";
$('.chkbx:checked').each(function() {
text += $(this).val() + ',';
});
text = text.substring(0, text.length - 1);
console.log(text)
$('#textbx').val(text);
});

jQuery last child val() undefined

This is my code:
$(document).on('change', '.item-checkbox', function () {
$(this).parent().find('.val-before').val();
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li id="li-14">
<input class="val-before hidden" type="text" value="checked">
<input type="checkbox" class="item-checkbox">
</li>
<li id="li-15">
<input class="val-before hidden" type="text" value="checked">
<input type="checkbox" class="item-checkbox">
</li>
</ul>
In li-14 or not li-15, val is "checked" or "unchecked"
In li-15, val is undefined
What's wrong?

try with prev() function
use $(this).prev('.val-before').val(); instead of this $(this).parent().find('.val-before').val();
$(document).on('change', '.item-checkbox', function() {
var val = $(this).prev('.val-before').val();
console.log(val);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li>...
<li id="li-14">
<input class="val-before hidden" type="text" value="checked">
<input type="checkbox" class="item-checkbox">
</li>
<li id="li-15">
<input class="val-before hidden" type="text" value="checked">
<input type="checkbox" class="item-checkbox">
</li>
</ul>

Have a look at this,
$('.item-checkbox').on('change', function () {
if($(this).val() == 'checked'){
$(this).prev().val('unchecked');
$(this).val('unchecked');
console.log($(this).prev().val());
}
else {
$(this).prev().val('checked');
$(this).val('checked');
console.log($(this).prev().val());
}
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<ul>
<li id="li-14">
<input class="val-before hidden" type="text" value="">
<input type="checkbox" class="item-checkbox">
</li>
<li id="li-15">
<input class="val-before hidden" type="text" value="">
<input type="checkbox" class="item-checkbox">
</li>
</ul>

I found the reason for this problem, not that jQuery css selector does not work, because the element id is repeated.

Checking checkboxes in jquery validation

I have several rows of checkboxes. The scenario is that when I click a checkbox in the first row, and when I click another checkbox in the second or third row and within the same column, the previous checked checkbox is unchecked and the new one is checked. This is working fine. My issue is that when I uncheck the newly checked checkbox, it should re-check the previous checkbox checked. Anyone who can help me with this please ?
The demo is as per below.
$('.js-cars-item [type="checkbox"]').change(function() {
var idx = $(this).closest('li').index(); //Get the index - Number in order
var chk = $(this).is(":checked"); //Get if checked or not
var obj = this; //Checkbox object
$('.js-cars-item').each(function() { //Loop every js-cars-item
//Find the checkbox with the same index of clicked checkbox. Change disabled property
$(this).find('li:eq(' + idx + ') [type="checkbox"]').not(obj).prop("checked", false);
});
var checkeds = [];
$(".cars-item input:checkbox:checked").each(function(index) {
checkeds[index] = $(this).attr('id');
});
console.clear();
console.log("These are checked:", checkeds);
})

I have updated your javascript code, please try this:
$('.js-cars-item [type="checkbox"]').change(function() {
var idx = $(this).closest('li').index(); //Get the index - Number in order
var chk = $(this).is(":checked"); //Get if checked or not
var obj = this; //Checkbox object
if(chk)
{ //If it is checked
$('.previous_'+idx).removeClass('previous_'+idx); //Remove the 'previous_$index' class from the checkbox
$('.js-cars-item').find('li:eq(' + idx + ') [type="checkbox"]:checked').not(obj).addClass('previous_'+idx).prop("checked", false); //set the 'previous_$index' class to an existing checked checkbox and remove the checked property
}
else if($('.previous_'+idx).length)
{ //If the 'previous_$index' class is available while uncheck the current checkbox
$('.previous_'+idx).prop("checked", true).removeClass('previous_'+idx); //set the 'previous_$index' class's checkbox to checked and remove this class
$(obj).addClass('previous_'+idx); //set the 'previous_$index' class to the currently unchecked checkbox
}
var checkeds = [];
$(".cars-item input:checkbox:checked").each(function(index) {
checkeds[index] = $(this).attr('id');
});
console.clear();
console.log("These are checked:", checkeds);

disable button when class on li doesnt exist

I want to prevent the button to be click when there are no item selected in the list. Only enable it when at least 1 in the list have highlight class.
HTML
<ul class="list">
<li><input type="checkbox" name="cat[]" id="1" value="227">
<label class="label-list" for="1">Select</label></li>
<li><input type="checkbox" name="cat[]" id="2" value="227">
<label class="label-list" for="2">Select</label></li>
<li><input type="checkbox" name="cat[]" id="3" value="227">
<label class="label-list" for="3">Select</label></li>
<li><input type="checkbox" name="cat[]" id="4" value="227">
<label class="label-list" for="4">Select</label></li>
</ul>
<input type="submit" id="search" class="btn-info" value="search" disabled>
SCRIPT:
$(".list .label-list").click(function() {
$(this).toggleClass("highlight");
});
CSS:
.highlight {background:red;}
FIDDLE
Tried to use this script but how do I toggle the attr from disabled to enabled?
if( $('.list .label-list').hasClass('highlight') === true )
{
$('#search').addClass('active');
}

You should rather test for is :checked like
var $checkb = $(".list").find("input[type='checkbox']"),
$search = $("#search");
$checkb.on("change", function(){
$search.prop("disabled", !$checkb.is(":checked"));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul class="list">
<li>
<label>
<input type="checkbox" name="cat[]" value="224">
Select
</label>
</li>
<li>
<label>
<input type="checkbox" name="cat[]" value="225">
Select
</label>
</li>
<li>
<label>
<input type="checkbox" name="cat[]" value="226">
Select
</label>
</li>
<li>
<label>
<input type="checkbox" name="cat[]" value="227">
Select
</label>
</li>
</ul>
<input type="submit" id="search" class="btn-info" value="search" disabled>

you can simple count all selected checkbox with this jquery selector
$('input[type=checkbox]:checked').length
this returns the total count of the checkbox selected
just add this event listener which occurs every time a checkbox value is change
$(document).on('change', 'input[type=checkbox]', function() {
var disabled = $('input[type=checkbox]:checked').length ? false: true;
$("#search").attr('disabled', disabled);
})
