• Why does it matter that in Javascript, scope is function-level, not block-level?

  - by Jian Lin

  In the question http://stackoverflow.com/questions/1451009/javascript-infamous-loop-problem the accepted answer from Christoph's says that JavaScript's scopes are function-level, not block-level What if Javascript's scopes are block-level, then would the Infamous Loop problem still occur? But will there be a different (or easier way) to fix it? Is it as opposed to other languages, where using a { would start a new scope?

• Still failing a function, not sure why...ideas on test cases to run?

  - by igor

  I've been trying to get this Sudoku game working, and I am still failing some of the individual functions. All together the game works, but when I run it through an "autograder", some test cases fail.. Currently I am stuck on the following function, placeValue, failing. I do have the output that I get vs. what the correct one should be, but am confused..what is something going on? EDIT: I do not know what input/calls they make to the function. What happens is that "invalid row" is outputted after every placeValue call, and I can't trace why.. Here is the output (mine + correct one) if it's at all helpful: http://pastebin.com/Wd3P3nDA Here is placeValue, and following is getCoords that placeValue calls.. void placeValue(Square board[BOARD_SIZE][BOARD_SIZE]) { int x,y,value; if(getCoords(x,y)) { cin>>value; if(board[x][y].permanent) { cout<< endl << "That location cannot be changed"; } else if(!(value>=1 && value<=9)) { cout << "Invalid number"<< endl; clearInput(); } else if(validMove(board, x, y, value)) { board[x][y].number=value; } } } bool getCoords(int & x, int & y) { char row; y=0; cin>>row>>y; x = static_cast<int>(toupper(row)); if (isalpha(row) && (x >= 'A' && x <= 'I') && y >= 1 && y <= 9) { x = x - 'A'; // converts x from a letter to corresponding index in matrix y = y - 1; // converts y to corresponding index in matrix return (true); } else if (!(x >= 'A' && x <= 'I')) { cout<<"Invalid row"<<endl; clearInput(); return false; } else { cout<<"Invalid column"<<endl; clearInput(); return false; } }

• How to call a javascript function from a servlet?

  - by sunnyj

  I submit a (jsp) form to a Servlet A. Then I handle some logic which would make the submission either a success or a failure. I use jquery's ajaxForm() function to re-direct the user to a different jsp after the Servlet logic is executed. But before this redirection happens I need to show a javascript notification showing whether the submission was successful or not. Can someone tell me how can I do this?

• Getting ORA Oracle error code using PHP function oci_connect?

  - by me_here

  The PHP function oci_connect (which connects to an Oracle database) just returns false if it fails, which at the moment I handle like this: $connection = oci_connect($username, $password, $database); if (!$connection){ return $result = "Trouble connecting to the Oracle Database"; } But really I'd like to have the actual ORA error code, so I can be more informative. Is this possible?

• Function that converts hex color values to an approximate color name?

  - by dclowd9901

  I don't suppose anyone knows of a function (PHP, preferably) that can take a hex color code and give an approximate color name for that hex value. I don't need a solution with 100s of colors. Even if it just amounted to the colors white, black, red, green blue, brown orange and yellow, I'd be pretty well in shape. If you don't know of an existing resource, does anyone know of a good way to approach this problem? Thanks in advance for the help.

• How to add custom function in onClick-event jqGrid-mode editGridRow?

  - by Anatoliy

  Firstly I used this call jQuery('#grid').jqGrid('editRow',id,true,pickdates);, it worked fine with UI Datepicker integration, but editRow is implemented for inline editing, but I prefer modal dialog, so I switched to editGridRow, now I can't find the way to call my custom function (pickdates) in onClick-event. My current call is jQuery('#grid').jqGrid('editGridRow',id,{closeOnEscape:true,width:400,savekey:[true,13]}); Thanks Anatoliy

• Is there a way to set a handler function for when a set of events has happened?

  - by allyourcode

  eg I have two concurrent AJAX requests, and I need the result from both to compute a third result. I'm using the Prototype library, so it might look something like this: var r1 = new Ajax.Request(url1, ...); var r2 = new Ajax.Request(url2, ...); function on_both_requests_complete(resp1, resp2) { ... } One way would be to use polling, but I'm thinking there must be a better way.

• Jython: is there a clean way to implement a Java interfaces with function references?

  - by auramo

  I know that I can implement a Java interface with Jython like this: class MyListener (Listener): def foo(self, event): print(str(event)) Python has first-class functions so that seems like an overkill - especially for interfaces with one method. Is there a way to just pass a lambda or function which implements a single method in an interface instead?

• Can one construct a "good" hash function using CRC32C as a base.

  - by DavidD

  Given that SSE 4.2 (Intel Core i7 & i5 parts) includes a CRC32 instruction, it seems reasonable to investigate whether one could build a faster general-purpose hash function. According to this only 16 bits of a CRC32 are evenly distributed. So what other transformation would one apply to overcome that? David

• Most inappropriate function or variable names you have encountered?

  - by Andrioid

  I was reading through my daily doze of RSS when I noticed a link to the python compiler documentation where class names like assList, assName and assTuple exist. While starting names with 'ass' is perfectly acceptable to me, it just sparked this idea that there probably exist much better examples of this. Have you personally used or otherwise encountered any inappropriate function or variable names? Personally I have used 'crap' and 'moo' for temporary purposes, forgot them and at a later point they came too integrated for me to bother with fixing them.
