javascript - After Initial Load Child_Added no longer returns full data -

-

I have a site where a user can order by selecting items in a menu

It is set up so that you press the "position order" button on the menu page

Then the ordered order appears on the order page.

On the orders.html page to load first, it shows all the data ok but whatever the added child does not load the rest of the data added, or it displays does not do. If I refresh all the loaded orders page

I may feel somewhat simpler, but I think where I found the fault.

Edit: Orders.html code from webpage. 

  var base = new firebase ('https://takeaway.firebaseio.com/'); ('Hair' added '', 'function' (snapshot), function (snapshot) {var orderdata = snapshot.val (); var contactname = orderdata.scope name; var contact number = orderdata contact number; var orderotal = orderdata Quotes; var command = "& lt; div class = 'openorder' gt; & lt; span class = 'name' & gt;" + contact name + "    }); Order = order + "& lt; / div> 
 gt; & lt; span class = 'total' & gt; + Order total "& lt; / span & gt; & lt; / div & gt; $ ('# Order') enclosed (order). });    
 
 
 tl;  
 In the firebase,  child_added  event triggers  only  when the child is added when the child is updated later,  Event is triggered.  
 causes your problem  
 In the menu.html, first you have to  push  popup a new order and then order items:  < Pre>  var description = base.chid ('order'). Push ({Contact Name: Contact Name, Contact Number: Contact Number, Total Cost: Total Cost}); Var detailRef = details.name (); $ ('# Selected & gt; walk away'). Each (function () {var itemName = $ (this). Child ("title"). Text (); var itemCost = $ (this) children (". (". "Chosen");  < / Pre> 
 Display more details on the order you  listen to  child_added  in order:  
  base.child ('order') ('Child_added', function (snapshot) {var orderData = snapshot.val (); var contactName = orderData. Contact; var contact number = orderdata contact number; var ordotool = orderdata totalcost; var order = "& lt ; Div class = 'openOrder' & gt; & lt; span class = 'name' & gt; "+ contactname +" + +  & gt; Lt; span class = 'number' & gt; "+ contact number +"   
 is turned on (function (ITEMST) {  
). At the time of the new order Items are not yet filled, so there is nothing to display / P> 
 when you add items, then on  child_added  event  order  There is no fire from, because there is no new order.  
 A Possible Solution  
 Solution First type the full command in menu.html and then press it on Firebase. Since you can arbitrarily send complex javascript objects into firebase, your data structure will be the same.  
 A simplified sample:  
  var order = {ContactName: ContactName, ContactNumber: Contact number, Total: TotalCast}; order. ITEMS = []; $ ('# Selected & gt; walk away'). Children ("(cost."). Push ({name: itemName, cost: itemCost});}); . Base.child ('command') push (order);   
 An added advantage is that it will save you a lot of time between the client and the server.

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...
