CHeckbox to update the database

Question

Good Day

 

Yesterday I tried to ask a question but I think I failed to explained what is it that I clearly searching for. I want an uncheck/check all checkbox, that when clicked all the values in the selected checkboxes be stored into the database, when unchecked be removed. Currently I have the checkbox that i working only to check and uncheck but not doing anything to the database (SQL Server).

<script type="text/javascript">
function toggleChecked(status)
{
$("#checkboxes input").each(function ()
{
$(this).prop("checked", status);
});
}
$(document).ready(function ()
{
// Changing state of CheckAll checkbox
$("#checkboxes").click(function ()
{
if ($("#checkboxes").length == $("#checkboxes input:checked").length)
{
$("#checkall").prop("checked", true);
}
else
{
$("#checkall").removeAttr("checked");
}
});
$("#checkall").click(function ()
{
var status = $("#checkall").prop('checked');
toggleChecked(status);
});
});
</script>
<b>
<label>
Check/Uncheck All
</label>
<label class="switch">
<input type="checkbox" id="checkall">
<span class="slider round">
</span>
</label>
</b>
<br />
<div id="checkboxes" style="height: 500px;position:relative;border:1px solid darkgray">
<div id="div2" style="max-height:100%;overflow:auto;">
<div id="suburbsDiv"></div>
