So, to pick out all of the unchecked checkboxes, you need to use the next jQuery selector code:
$('enter[type=checkbox]:not(:checked)')
It first will get all enter parts with kind because the checkbox after which these for which checked property shouldn’t be outlined, i.e. all of the uncheck checked bins. You may as well use the jQuery selector:
$("enter:checkbox:not(:checked)")
however utilizing enter[type=checkbox] is quicker and you need to keep it up.

jQuery instance to get all unselected checkboxes
Nothing is healthier than a easy instance to see issues working. Although the answer in jQuery is normally one-liner, you want somewhat bit extra to make use of it virtually.
For instance, it’s worthwhile to use the every() perform to iterate by means of every unselected checkbox to do one thing like printing their title, id, and worth or cleansing them for the subsequent spherical. If you wish to be taught extra in regards to the frequent jQuery capabilities like val() and attr() and others then I additionally recommend you undergo The Full jQuery course on Udemy.
Anyway, this jquery instance offers you a working platform.
<html> <head> <title>Methods to discover all unchecked checkboxes in jQuery</title> </head> <physique> <h2>Getting all unchecked checkboxes worth in jQuery</h2> <enter kind="checkbox" id="learn" checked="checked" /> <enter kind="checkbox" id="write" checked="checked" /> <enter kind="checkbox" id="converse" /> <div id="output"></div> <script src="http://code.jquery.com/jquery-1.6.2.min.js"></script> <script> $(doc).prepared(perform(){ $('enter[type=checkbox]:not(:checked)').every(perform(){ var standing = (this.checked ? $(this).val() : ""); var id = $(this).attr("id"); $('#output').append("<h3>" + id + " : " + standing + "</h3>"); }); }); </script> </physique> </html>And, right here is the output of the code once I run it by first unchecking one checkbox after which subsequently un-checking two and three checkboxes.
