javascript - How do I make my live jQuery search wait a second before performing the search? -

-

I have a search input that sends the data to a php file from an input as I write the PHP file to my database Finds a list and shows a list of search options. You know, AJAX is looking for style live.

My problem is, if you type something very fast, then it can only stop searching for 1 or 2 characters, even if 10 others have been typed it creates some problems .

My jquery looks like this: 

  $ (document) .ready (function () {$ ('# searchMe') .keyp (function () {lookup (This.value);});});

and 

  function lookup (search input) {if (searchinput.length == 0) {// hide suggestion box $ ("#suggestions") Hide () .; } And {$ ('# Loading'). FadeIn (); $ .post ("/ RPCsearch.php", {queryString: "" + searchinput + ""}, function (data) {if (data.lamp & gt; 0) {$ ("# suggestion") .html ) Show (); $ ('# Loading'). FadeOut ();}}); }} // Lookup

So I'm just curious, how can I do this so that my script will wait until I finish typing before running the function? My argument says something like that one key has not been pressed for 200 microsoft seconds, run the function, otherwise press for a while.

How is this done?

Easy, by using Of course you only want to run one timer once, so it is important to use it at the beginning of the function ... 

  $ (function () {var timer; $ ("# searchMe" ) .keyup (function () {clearTimeout}} var ms = 200; // milliseconds var val = this.value; timer = setTimeout (function () {lookup (val);}, ms);});} );

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...
