javascript - How to add items to a specific dictionary within an item in a list with AngularFire? -

-

The code below shows a list from the firebase and shows the related comment field for each item in the list. The user can comment on that item and it will update the comment field for that item in the list. Currently, every time a comment is made, it overwrites the previous one, but I would like to save all the comments.

How do I make it, so that every comment should be added every time, the last ones are also saved?

indx.html 

  & lt; Div ng-app = "MyApp" ng controller = "MyCtrl" & gt; & Lt; Div ng-repeat = "data (id, item)" & gt; & Lt; H2 & gt; {{Item.title}} & lt; / H2 & gt; & Lt; Input ng-model = "item.comment" & gt; & Lt; / Input & gt; & Lt; Button type = "submit" ng-click = "add comment (id)" & gt; Comment & lt; / Button & gt; & Lt; / Div & gt; & Lt; / Div & gt;   
  app.js   
  angular.module ('MyApp', ['firebase']) .controller ('MyCtrl 'function MyCtrl ($ scope, $ firebase) {var deflect = "https://helloworldtest.firebaseio.com"; var ref = new Firebase (inflection); $ scope.data = $ firebase (ref); $ scope. CommentAdd = function (id) {$ scope.data. $ Save (id);};});   
 The following is the data structure that is generated within the firebase {helloworldtest: {-JSQhsAnY5zhf0oVKfbb: {title: "nameA", comment: "second comment"}, -JSQhsAnY5zhf0oVKfbb: {title: "Name B", Comment: "Second Comment"}}}  
 However, I want to create the following where there is a 'comment' branch with all the comments. {Comment: "Comment": {Comment: "Second Comment"}, - JSQhsAnY5zhf0oVKfbb: {Comment: "First Comment", {comment: {comment: {- JSQhsAnY5zhf0oVKfbb: }}}, {-JSQhsAnYdfdfdffbb: {title: "nameA", comments: {- JSQhsAnY5zhf0oVKfAb: {note: "another commented"}, - JSQhsAnY5zhf0oVKfbb: {note: "first comment"}}}}   
 I have tried to change it  
  $ scope.data $ Save (id); With   
  
  $ scope.data. $ Add (id);   
 I have also tried to use:  
  $ scope.data [id]. $ Add ({foo: "bar"})    
 
 
 In a comment field Instead of saving comments, use a list as a comment and use  push  or  $ add . 
 
 Controller = "MyCtrl" & gt; & Lt; Div ng-repeat = "data (id, item)" & gt; & Lt; H2 & gt; {{Item.title}} & lt; / H2 & gt; & Lt; Input ng-model = "new comment" & gt; & Lt; / Input & gt; & Lt; Button type = "submit" ng-click = "add comment (id, new comment)" & gt; Comment & lt; / Button & gt; & Lt; / Div & gt; & Lt; / Div & gt; MyCtrl ($ scope, $ firebase) {var furl = "https://helloworldtest.firebaseio.com"; Var ref = new firebase (Fell + '/ item'); $ Scope.data = $ firebase (referee); Var $ comments = $ firebase (commentsRef); $ Scope.addComment = function (id, new comment) {ref.child (id) .child ( 'comments'). Push (newcomment); }; });   
 In addition to this. Instead, consider keeping the comments in their own way in their own way.

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...

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...
