Checkbox disabled not returning result from stored checkbox array
I am storing all checkboxes what my div has in to a variable, later i am
finding disabled from the stored variable, but i am not get proper result,
instead if I find separately I am getting proper result..
what why i am not find the disabled from my stored variable?
here is my code:
var checkedBoxes = $(".locale-container .panel ul
li").find("input:checkbox"),
disabledBoxes = checkedBoxes.find("input:checkbox:disabled");
// not getting
But "disabledBoxes" not getting result from checkBoxes.
In case if I do like this:
var checkedBoxes = $(".locale-container .panel ul
li").find("input:checkbox"),
disabledBoxes = $(".locale-container .panel ul
li").find("input:checkbox:disabled"); // it works
so how can i filter or get the appropriate checkboxes from stored variable?
Thanks in advance

How does compiler resolves virtual functions accessing non-virtual data members C++
How does compiler resolves virtual functions accessing non-virtual data
members C++
I was reading about the C++ Objects when I got this doubt. Suppose there
are two classes
class X
{
virtual int def() { };
}
class Y
{
virtual int abc() { };
}
class Z : public X,public Y
{
virutal int abc() { return a };
int a;
}
Now what I understand is both Y and Z have the reference to Z::abc() in
their virtual tables which helps to resolve the correct function to call.
Consider
Y *y = new Z;
Z *z = new Z;
y->abc() // I understand this is done by reaching the vptr of y by this =
this + sizeof (X)
and z->abc() // z has its own vptr reachable
My understanding is that in both the cases the "this" pointer is passed
and after finding out the correct abc() to call, how does the programm
reach the int value "a"?
How does the compiler calculate the address of " int a" correctly based on
type of the object passed?

Access to an array element with PHP
Access to an array element with PHP
To avoid multiple mysql SELECT queries I try to take the SELECT out of the
foreach-loop.
The query is
SELECT o.orders_id,
o.date_purchased,
o.orders_status,
ot.text AS order_total,
os.orders_status_name
FROM " . TABLE_ORDERS . " o
JOIN " . TABLE_ORDERS_TOTAL . " ot ON (o.orders_id = ot.orders_id AND
ot.class = 'ot_total')
JOIN " . TABLE_ORDERS_STATUS . " os ON (o.orders_status =
os.orders_status_id AND os.language_id = " .
(int)$_SESSION['languages_id'] . ")
WHERE o.customers_id = " . (int)$_SESSION['customer_id'] . "
ORDER BY orders_id DESC
As the result I get the array called $history_result['RESULT'] and it
looks like
Array
(
[0] => Array
(
[orders_id] => 309
[date_purchased] => 2013-10-02 15:49:54
[orders_status] => 1
[order_total] => 9,00 €
[orders_status_name] => Offen
)
[1] => Array
(
[orders_id] => 308
[date_purchased] => 2013-10-02 15:39:54
[orders_status] => 1
[order_total] => 9,00 €
[orders_status_name] => Offen
)
[2] => Array
(
[orders_id] => 307
[date_purchased] => 2013-10-02 15:33:48
[orders_status] => 1
[order_total] => 9,00 €
[orders_status_name] => Offen
)
)
In the following foreach-loop is the next MySql-Query
foreach ($history_result['RESULT'] as $history) {
$trackings = $db->result("-- 03 account_history_info.php
SELECT o.ortra_parcel_id,
c.carrier_tracking_link,
c.carrier_name
FROM " . TABLE_ORDERS_TRACKING . " o
JOIN " . TABLE_CARRIERS . " c ON o.ortra_id = c.carrier_id
WHERE ortra_order_id = " . $history['orders_id']
);
}
How can I access directly to the array element 'orders_id' so that I could
create an SQL statement like
$trackings = $db->result("-- 03 account_history_info.php
SELECT o.ortra_parcel_id,
c.carrier_tracking_link,
c.carrier_name
FROM " . TABLE_ORDERS_TRACKING . " o
JOIN " . TABLE_CARRIERS . " c ON o.ortra_id = c.carrier_id
WHERE ortra_order_id IN = " . implode(',', $fooArray)
);

Why dont all my textviews update with 1 button clicks? Requires multiple clicks
Why dont all my textviews update with 1 button clicks? Requires multiple

I have a simple tablelayout with many textview. When the button is pressed
only a few are updated, but what happens is that, you need to press the
button mutiple times for all the textviews to get updated. Why dont they
all change on the first/only click?

Why use typedef for iterators in template classes
Why use typedef for iterators in template classes
I read the following post: Why use typedef-typename in templates
I am reading up on some material which says you must have public typedef
for the following private nested class
template<typename T>
class list
{
private:
class my_private_it
{
public:
...
};
public:
typedef my_private_it iterator;
// should this be:
// typedef typename my_private_it iterator;
...
iterator begin(){return iterator(this)};
iterator end(){return iterator(NULL)};
};
Now from the aforementioned link, I understand, the typename is to help
the compiler deduce that it is infact working with types and not values
for certain dependent names. But why do people use the typedef? Is this
compiler requirement or standard requirement. Please note I understand the
typename part , but not the typedef part.
