My purpose
When I click Check All
in the first column, all check boxes in that column should be checked and the Set button should show up. While the other check boxes in other column should be unchecked. Besides, when I click Check All
in the second column, the Set button in the first column will be hidden and show up in the second column and then uncheck other check boxes.
HTML CODE :
<div id="allCheckboxes">
<table width="500px">
<tr>
<td>Check ALL <input type="checkbox" id="checkAll_1"><div id="setBttn_1" style="display:none;"><input type="button" value="Set"></div></td>
<td>Check ALL <input type="checkbox" id="checkAll_2"><div id="setBttn_2" style="display:none;"><input type="button" value="Set"></div></td>
<td>Check ALL <input type="checkbox" id="checkAll_3"><div id="setBttn_3" style="display:none;"><input type="button" value="Set"></div></td>
</tr>
<tr>
<td><input type="checkbox" id="chkBox1" name="Box1" checked value="1" /></td>
<td><input type="checkbox" id="chkBox2" name="Box2" value="12"/></td>
<td><input type="checkbox" id="chkBox3" name="Box3" value="13"/></td>
<tr>
<td><input type="checkbox" id="chkBox10" name="Box1" checked value="001" /></td>
<td><input type="checkbox" id="chkBox20" name="Box2" value="182"/></td>
<td><input type="checkbox" id="chkBox30" name="Box3" value="123"/></td>
</tr>
<tr>
<td><input type="checkbox" id="chkBox11" name="Box1" value="333" /></td>
<td><input type="checkbox" id="chkBox181" name="Box2" value="184442"/></td>
<td><input type="checkbox" id="chkBox101" name="Box3" checked value="1243"/></td>
</tr>
</table>
</div>
jQuery :
$('input[type="checkbox"]').on('change', function() {
$(this).closest('tr').find('input').not(this).prop('checked', false);
});
$('#checkAll_1').change(function () {
$('[name="Box1"]').prop('checked', $(this).prop("checked"));
if($('#checkAll_1').is(':checked')) {
$('#setBttn_1').show();
} else {
$('#setBttn_1').hide();
}
});
$('#checkAll_2').change(function () {
$('[name="Box2"]').prop('checked', $(this).prop("checked"));
if($('#checkAll_2').is(':checked')) {
$('#setBttn_2').show();
} else {
$('#setBttn_2').hide();
}
});
$('#checkAll_3').change(function () {
$('[name="Box3"]').prop('checked', $(this).prop("checked"));
if($('#checkAll_3').is(':checked')) {
$('#setBttn_3').show();
} else {
$('#setBttn_3').hide();
}
});
The current result is when I click Check All
in the first column, it won't uncheck other check boxes. When I click Check All
in the second column, the Set button in the first column won't hide. Is it possible to go back to the previously checked option(s) just before the current selection if I unclick "Check All"?

The problem is that prop
does not fire change (with good reason, as that could cause recursive events by default).
You can simply trigger the change()
event after setting prop
, but you need to ensure it does not fire recursively (so added a sentinel variable):
var processing = false;
$('input[type="checkbox"]').on('change', function() {
if (!processing) {
processing = true;
$(this).closest('tr').find('input[type="checkbox"]').not(this).prop('checked', false).trigger('change');
processing = false;
}
});
JSFiddle: http://jsfiddle.net/TrueBlueAussie/WzuMa/143/
var processing = false;
var $checkboxes = $('input[type="checkbox"]');
$checkboxes.on('change', function() {
if (!processing) {
processing = true;
if (this.checked){
// Store all answers on a data attribute
$checkboxes.each(function(){
$(this).data('lastcheck', $(this).prop('checked'));
});
$(this).closest('tr').find('input[type="checkbox"]').not(this).prop('checked', false).trigger('change');
}
else {
// Restore all the previous checked box states
$checkboxes.not(this).each(function(){
$(this).prop('checked', $(this).data('lastcheck')).removeData('lastcheck');
});
}
processing = false;
}
});

You can tweak this technique to operate on rows instead, for the lower checkboxes but I have to leave something for you to do :)

Try below JS for now things are hard-coded but if this solution is as expected as you then I can update it to more dynamics
$('input[type="checkbox"]').on('change', function() {
$(this).closest('tr').find('input').not(this).prop('checked', false);
});
$('#checkAll_1').change(function () {
$('[name="Box1"]').prop('checked', $(this).prop("checked"));
$('[name="Box2"],[name="Box3"]').prop('checked', false);
if($('#checkAll_1').is(':checked')){
$('#setBttn_1').show();
$('#setBttn_2,#setBttn_3').hide();
}else{
$('#setBttn_1').hide();
}
});
$('#checkAll_2').change(function () {
$('[name="Box2"]').prop('checked', $(this).prop("checked"));
$('[name="Box1"],[name="Box3"]').prop('checked', false);
if($('#checkAll_2').is(':checked')){
$('#setBttn_2').show();
$('#setBttn_1,#setBttn_3').hide();
}else{
$('#setBttn_2').hide();
}
});
$('#checkAll_3').change(function () {
$('[name="Box3"]').prop('checked', $(this).prop("checked"));
$('[name="Box1"],[name="Box2"]').prop('checked', false);
if($('#checkAll_3').is(':checked')){
$('#setBttn_3').show();
$('#setBttn_1,#setBttn_2').hide();
}else{
$('#setBttn_3').hide();
}
});

You can use this:
$('#allCheckboxes').find('tr').first().find(':checkbox').on('change', function(e) {
var $this = $(this),
idx = $this.closest('td').index();
$('div[id^="setBttn"]').hide();
$this.next('div').toggle(this.checked);
$('[id^="checkAll"]:checked').not(this).prop('checked', !this.checked);
$('#allCheckboxes').find('tr').not(':first').each(function() {
$(this).find(':checkbox:checked').prop('checked', !$this.prop('checked'));
$(this).find('td').eq(idx).find(':checkbox').prop('checked', $this.prop('checked'));
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="allCheckboxes">
<table width="500px">
<tr>

You you are programmatically setting the checked
property it doesn't triggers the change
event handler.
To trigger the event handler, .trigger(event)
function should be used.
$('input[type="checkbox"]').on('change', function() {
$(this).closest('tr').find('input').not(this).prop('checked', false);
});
$('#checkAll_1').change(function() {
$('[name="Box1"]').prop('checked', $(this).prop("checked")).trigger('change');
if ($('#checkAll_1').is(':checked')) {
$('#setBttn_1').show();
} else {
$('#setBttn_1').hide();
}
});
$('#checkAll_2').change(function() {
$('[name="Box2"]').prop('checked', $(this).prop("checked")).trigger('change');
if ($('#checkAll_2').is(':checked')) {
$('#setBttn_2').show();
} else {
$('#setBttn_2').hide();
}
});
$('#checkAll_3').change(function() {
$('[name="Box3"]').prop('checked', $(this).prop("checked")).trigger('change');
if ($('#checkAll_3').is(':checked')) {
$('#setBttn_3').show();
} else {
$('#setBttn_3').hide();
}
});
