jquery ajax problem -

-

A few days ago I posted this question:
who created a series of divs using this code with me ( "+ I). SlideDown () seems ("input") addClass ("SomeClass") .; }

My problem is that I now need to get the values ​​of each #play div and send it to a php script via AJAX. If I had a certain number of divs, then I could do it easily, but how do I have to do it when I do not know how many #play will be?

More details!

It seems that I did not explain clearly in my basic question, so I will try and explain things better.
I want to use an AJAX phone in the remote php script. $ .pos t jQuery method I can send the information of remote scripts very easily. Here's an example: 

  $ ("# submit"). Click (function () ($ {. .post ("..// include / process.php", {play_0: $ ("(" # play \ _2 "). Val (), play_3: $ (" # play (" (Play);} ();} ();};);};};};} The php script can now access this information via the $ _POST array - just like a normal form submission. 
 If I can generate divs (#play_) using a loop, then the way I I did the above, the 'rigid code' in that the  $ .post  method really contained me in the syntax There is a need to include a loop somewhere - I can not work to do this work! I hope that it has made things clear.

is jQuery selector, then you can easily loop through them Create your object ... 

  // An empty object Data = {}; // all & lt; div & gt; those elements have an ID attribute that starts with "play_" var divs = $ ("div [id ^ = play_]"); // l & Gt; Div & gt; Elements, each function of jQuery using divs.each (function () (// current jQuery with div we are looping div = $ (this); // current div var id = div.attr (" Id "); // The value of the current div var val = div.html (); // object properties can be set dynamically in javascript data [id] = val;}; // is looped, All properties have been warned (data.play_0);

c# - ListView onScroll event -

-
I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
