How To Set Value Of Checkbox When Checked And Unchecked Using Ajax Or Jquery

I need to get the value of the checkboxes when checked and unchecked and save it in database. The value is 1 if checked and 0 if unchecked, respectively. I am currently using the s

Solution 1:

Probably you want this:

$('input[type="checkbox"]').click(function () {
    $(this).prop("checked") ? $(this).val("1") : $(this).val("0")
});

<scriptsrc="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputtype="checkbox"value="1"name="one_by_one"id="one_by_one"class="one_by_one">One

Solution 2:

The value of a checkbox never changes (by itself). If the checkbox is not checked its value simply won't be sent to the server. So at the server side you should check whether one_by_one is included in the request and set the value accordingly (e.g. set 0 if it doesn't exist or the value of one_by_one if it does).
