javascript - Array not passing with ajax. -

-

This is a Java code code for AJAX calls. In this case, get the code variable AC program code and pass it on the compiler.php page.

() {var code = Document.getElementById ("file_cont") value; Var arr = New array (code, "c"); Warning (arrival [0]); Var xmlhttp; If (window.XMLHttpRequest) {xmlhttp = new XMLHttpRequest (); } And {xmlhttp = new ActiveXObject ("Microsoft.XMLHTTP"); } Xmlhttp.onreadystatechange = function () {if (xmlhttp.readystate == 4 & xmlhttp.status == 200} {//window.location.assign("login.php "); Warning (xmlhttp.responseText); }} Xmlhttp.open ("POST", "server_controlers / compiler.php? Q =" + JSON.stringify (arr), true); xmlhttp.send ();}

Ajax call works well but the case is in php file. I am decoding the Jason array for the $ arr variable but if I echo this way < Code> echo $ arr [0] This is empty but if I type the code for the array in the Java script like var arr = new array ("aaa", " C ") in I do not get it; Its working fine Some can tell me that when I send the array with the code variable then what is wrong? This is a php file. 

   

  server_controlers / compiler.php? Q = "+ JSON.stringify (AR)

Your data is not being made secure URL. You say that there is c in the code, it means That is, in this case (for example) the & Amp; character that breaks the string string format and JSON will be invalid if it is removed from it.

encodeurIComponent to run it is in your URL.

server_controlers / compiler.php? Q = "+ encodeurIComponent (JSON.stringify (arr))

python - Writing Greek in matplotlib labels, titles -

I'm trying to write some text for labels, shape titles etc. with my plots, but no benefit till now Has not happened . I do not want to print specific characters (I know how to use special characters), I want to write the entire text in Greek (maybe Unicode and text ' ?). , suggesting that I would like to mention that for some reason I can not get matplotlib to cooperate with Tex (using IPython notebook from Anaconda in Ubuntu 14.10) so that there really is an option Will not be the first. I tried loading the Arial font and it loads successfully but again I get square blocks instead of characters. I import matplotlib.font_manager FM PROP = FM Font Properties (fname = '/ usr / share / fonts / truetype / msttcorefonts / Arial.ttf') And then to display the string I u'Î? ? I ?? Î¿Ï ??

c# - LINQ to Entities does not recognize the method 'Int32 IndexOf(System.String, System.StringComparison)' method -

I have performed a linq query using Entityframework as below GroupMaster getGroup = Null; GetGroup = DataContext.Groups.FirstOrDefault (item = & gt; keyword.IndexOf (item.Keywords, StringComparison.OrdinalIgnoreCase)> = 0 & amp; amp; item.ISNAmd) I found an exception like the method when executing it LINQ units do not recognize the 'Inter 32 index of (system string, system. String compromise)' method, and This method can not be translated to Store expression. Includes () method is sensitive by default, then I need to convert to minimize. Is there any method in which a string match match is examined and whether there is any method to solve the index question of the method? You actually have four options Databases globally Change the colon of it can be done in many ways, a simple Google search should reveal to them. Change the mix of individual tables or columns. Use a stored procedure and specify the call statement on your query Perform...

Pygame memory leak with transform.flip -

-
Today I came across an interesting issue which, by writing a small side scroller, instead of a sprite sheet, I was planning to use because I lacked a good "packer" for making phantom sheets (and honestly with patience and passion as it is only a test project). Anyway, I showed the animation running on the right of 8 PNG (with transparency). I considered it a good idea to prepare the flipped images to run on the left in the consultant, and the frame is not framed when the game is running (Flip actually consumes a lot of CPU like I Was measured). > To get access to the loop, I get the memory leak self.move_l = [# 8 PNG images with transparency to the right] For the self in IMG. Move_l: self.move_r.append (pygame.transform.flip (img, true, false) error traceback: traceback (most recent Call final): The file "D: \ Python 34 \ _Projects \ efg \ efg.py", in line 196, in the & lt; module & gt; main = master program ((1024, 680)) "D: \ Python ...
