How to change checkbox value?

change value of checkbox doesn't work.
This is my code:
$(document).change('add',function() {
$(".activateuploadedpic").click(function(){
if ($(this).val()=='true') {
$(this).attr('value','false');
}
else {
$(this).attr('value','true');
}
});
});

You can change to this:
$(".activateuploadedpic").click(function () {
$(this).attr("value", $(this).prop("checked"));
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="checkbox" value="false" class="activateuploadedpic" />

check all checkbox with hide

How do I add a checkbox that can check all the checkboxes if it's checked?
How can I add show/hide functionality to the "check all" checkbox.
The submit button also need to be showed if the check all checkbox is checked.
$(document).ready(function() {
var $submit = $("#submit_prog").hide(),
$cbs = $('input[name="prog"]').click(function() {
$submit.toggle( $cbs.is(":checked") );
});
});
<input type="checkbox" name="?" value="?"> // check all checkbox
<input type="checkbox" name="prog" value="1">
<input type="checkbox" name="prog" value="2">
<input type="submit" id="submit_prog" value='Submit' />

assumption id of select all chckbox is selall.
create a class for all the check box you want to select using select all
$('#selall').click(function(event) {
if(this.checked) {
// Iterate each checkbox
$('.yourchckbox').each(function() {
this.checked = true;
});
$('#submit_prog').show();
}
else {
$('.yourchckbox').each(function()
{ this.checked = false; });
$('#submit_prog').hide()
}
});
$('.yourchckbox').click(function(event) {
if(!(this.checked)) {
$('#selall').prop('checked', false);
}
});

Give the select all check box an id, say selectall then
$('#selectall').click(function(){
if (this.checked){
$('input[name="prog"]').prop('checked', true);
$submit.toggle( true );
}
});
if you want the checkboxes to be unselected if the select all in unselected
$('#selectall').click(function(){
$('input[name="prog"]').prop('checked', this.checked);
$submit.toggle( this.checked);
});
$cbs = $('input[name="prog"]').click(function() {
$submit.toggle( $cbs.filter(':checked').length == 0 );
if (!this.checked) $('#selectall').prop('checked', false);
});

Try
$('input:checkbox[name!="prog"]').click(function(){
$('input:checkbox[name="prog"]').prop('checked', $(this).is(':checked'))
})
Or if you can change checkbox id to selall
$('#selall').click(function(){
$('input:checkbox').prop('checked', $(this).is(':checked'))
})

Its quite simple.
lets name this checkbox <input type="checkbox" name="check_all" value="1">
And now add event:
$('input[name="check_all"]').click( function() {
if( $(this).is(':checked') ) {
$('input[name="prog"]').attr('checked', 'checked');
} else {
$('input[name="prog"]').removeAttr('checked');
}
$('input[name="prog"]:eq(0)').change(); //firing event which we will catch
});
Then we should check if all input[name="prog"] are checked:
$('input[name="prog"]').change( function() {
if( $('input[name="prog"]:not(:checked)').length ) {
$('#submit_prog').hide();
} else {
$('#submit_prog').show();
}
});

select all checkboxes on #all check and check #all when all checkboxes are checked
<SCRIPT language="javascript">
$(function(){
$("#all").click(function () {
$('.one').attr('checked', this.checked);
if (this.checked) {$('#submit_prog').hide();}
(this.checked)?$('#submit_prog').show():$('#submit_prog').hide();
});
$(".one").click(function(){
if($(".one").length == $(".one:checked").length) {
$("#all").attr("checked", "checked");
$('#submit_prog').show();
} else {
$("#all").removeAttr("checked");
$('#submit_prog').hide();
}
});
});
</SCRIPT>
Change id and class of checkboxes
<input type="checkbox" id="all" > // check all checkbox
<input type="checkbox" name="prog" class="one" value="1">
<input type="checkbox" name="prog" class="one" value="2">

Checking all checkboxes at once with Javascript

This function alerts right totalqt only when I check checkboxes one by one. But doesn't work properly for #check_all: alerts totalqt = 0.
What I did wrong, can anyone explain?
var totalqt=0;
$('#check_all').click( function() {
$('.checkbox').click();
alert(totalqt);
} );
$('.checkbox').click(function(e) {
e.stopPropagation();
if($(this).closest("tr").not('#hdr').hasClass("row_selected")){
$(this).closest("tr").not('#hdr').removeClass("row_selected");
totalqt=totalqt - parseInt($(this).closest("tr").find("#qt").text(), 10);
}
else {
$(this).closest("tr").not('#hdr').addClass("row_selected");
totalqt=totalqt + parseInt($(this).closest("tr").find("#qt").text());
}
HTML looks like that
<tr>
...
<td><input type="checkbox" name="checkbox[]" method="post" value="" class="checkbox"/></td>
...
</tr>

actually when the checkbox is changed manualy it doesn't trigger handler. try something like this.
function doIt(obj){
if($(obj).closest("tr").not('#hdr').hasClass("row_selected")){
$(obj).closest("tr").not('#hdr').removeClass("row_selected");
totalqt=totalqt - parseInt($(obj).closest("tr").find("#qt").text(), 10);
}
else {
$(obj).closest("tr").not('#hdr').addClass("row_selected");
totalqt=totalqt + parseInt($(obj).closest("tr").find("#qt").text());
}
}
then
$('.checkbox').click(function(e) {
e.stopPropagation();
doIt(this);
});
and
$('#check_all').click( function() {
if($(this).prop('checked')){
$('.checkbox').each(function(){
$(this).prop('checked', true);
doIt(this);
alert(totalqt);
});
}else{
$('.checkbox').each(function(){
$(this).prop('checked', false);
doIt(this);
alert(totalqt);
});
}
} );

I have changed my answer to the following, try this:
<div class="checkall">
<input type="checkbox" id="checkall">
</div>
<div id="list">
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
<input type="checkbox" />
</div>
and jquery:
var checkboxes = $(":checkbox", "#list").change(function() {
var allIsChecked = checkboxes.length === checkboxes.filter(":checked").length;
checkAll[0].checked = allIsChecked;
});
var checkAll = $("#checkall").change(function() {
checkboxes.prop("checked",this.checked);
});
