ajax - Jquery executes in weird order -

-

Please refer to this code. I hope this is:

  1. Execute the executable which saves two values ​​( latitude and longitude )
  2. Use these values ​​here = var center = new google.maps.LatLng (resplat, resplon);

    The problem is that the code does not execute in this sequence. It "jumps" on the initial ajax and goes for a second time when it comes back first. This makes me two worthless useless. Can the code explain the logic behind the order being executed? 

      function initialize () {$ .ajax ({type: "GET", url: 'http: // ip-api .com / json', datatype: "Jason", success: Work (resp) {resplat = resp.lat; resplon = resp.lon;}}); // Google has touched its interface to some extent - it asks the API to use that new UI google.maps.visualRefresh = true; Var center = new google.maps.LatLng (resplat, resplon); // These are the options which set the initial zoom level, where the map is centered to start at the world level, and to show the map map var map = {zoom: 15, center: center, map type Do: google.maps.MapTypeId.G_NORMAL_MAP};    
     
     
     Move that code to  reslat  and  Start the   inside   
      function of AJAX success callback () {$ .ajax ({type: "GET", url: 'http: // Ip -api.com/json ', datatype: "Jason", success: function {var resplat = resp.lat; var resplon = resp.lon; // Google has touched its interface to some extent - This tells that the new UI google.maps.visualRefresh = true; var center = new google.maps.LatLng (resplat, resplon); // These are the options that set the initial zoom level, where the map starts globally Second is concentrated, and the type of map to show Var map == {zoom: 15, center: Center, type map: google.maps.MapTypeId.G_NORMAL_MAP};}}); }   
      $ Ajax  is an async call as long as the data does not come ( success  handler) you have to do  wait  then you can use it.  
     Another way to add  .done (foo)  handler:  
      $. Ajax ({.. ..}). Done (function (...) {/ * doing something});

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
