javascript - JQuery effect working in firefox; not chrome / ie -

-

This problem makes me wonder because it does not even work in Chrome chrome !!
Anyway, I have 3 selection boxes, A, B, C. On page loads, B and C are hidden (this is okay in all browsers). Currently, I have an event handler attached to specific values ​​in box A, so if a value is clicked, then B. indicates that there is population along with the results for C. The only thing for C: If a value is clicked in B, then C will show itself.
However, this "show" effect is only in Firefox - Chrome and IE are confusing.

Any suggestions? Hint? Here are some code: 

  $ (document) .ready (function () {$ ("# B"). Hide (); $ ("# c"). Hide (); $ ('Choose #A option'). Each (function () {$ (this). Click (function () {$ .getJSON (luggage, callback (data));});});}); Function callback (data) {// alert ("hi"); // It is not working for Chrome / IE! Therefore, callback is not called $ ("#b"). Show (); // It is not working for Chrome / IE! }; Edit: Turns it, 'Select #A option' - 'Option' tag was buggy after "making changes" to my handler, I debug and debug it. It was capable until I removed the option tag - everything seems to work now.  
 Thanks, Micheal   
 
 
 The real problem is in the following line: / P> 
  // ... $ .getJSON (luggage, callback); // ...  
 
 You are not passing the callback function, you are actually executing the function and passing  undefined  because it returns anything does not do. 
 
 You should reference only the function: 
 
  // ... $ .getJSON (luggage, callback); // ...  
 
 Or use an anonymous function in place: 
 
  // ... $ .getJSON (luggage, work (data ) {$ ("#b"). Show ();}); // ...  
 
  Edit:  I have not seen about the click handler which you are trying to assign, I recommend using an option to ensure that an option is chosen: 
 
  $ (document) .ready (function () {$ ("# B, # C") Change (function () {$ .getJSON (Accessories, Functions (Data) {$ ("#b"). Show ();});});} );

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...
