javascript - Filtering data-foreach rendering view with option dropdown, BatmanJS -

-

I simply try to manipulate a populated table by Batman JS to filter the entries with a dropdown option box I am doing

(html view code) 

  & lt; Select Data-Bind = "Itemview" & gt; & Lt; Option Data- foreach-item = "items" data-bind = "item.key1" data-bind-value = "item.key1" & gt; & Lt; / Options & gt; & Lt; / Select & gt; & Lt; Table & gt; & Lt; Tr class = "key" & gt; & Lt; Th class = "label" data-bind = "keys. Key1" & gt; & Lt; / Th & gt; & Lt; Th class = "label" data-bind = "keys .key2" & gt; & Lt; / Th & gt; & Lt; Th class = "label" data-bind = "keys .key3" & gt; & Lt; / Th & gt; & Lt; / TR & gt; & Lt; Tr class = "item" data-foreach-item = "items" & gt; & Lt; Td square = "name" data-bound = "item.key1" & gt; & Lt; / Td> & Lt; Td square = "number1" data-bound = "item .key2" & gt; & Lt; / Td> & Lt; Td square = "number2" data-bind = "item .key3" & gt; & Lt; / Td> & Lt; / TR & gt; & Lt; / Table & gt;   
 I have lost a lot from the point of view of this problem. My initial thought was to use coffeescript to select 'item' elements and declare it as "Display: None",  
   and coffeescript filterView => - obsolete = obj.options [obj.selectedIndex] .value; temp = document.getElementsByClassName ("item") temporary name For element = getElementsByClassName ("name"). InnerHTML not selected the name if the element element.style.display == "none"   
 But I stuck at this point slightly, I'm wondering if there is any way to handle it with Batman Filters. / P>  
 
 
 Using the  data-protected  binding  Item1key  is selected.  
 When you select an item from the dropdown, its  key1  is  item value , so that you may be able to check for:  
  & lt; tr data-foreach-item = "items" data-showif = 'item .key1 | equals object | ue '& gt; & lt; td class = "name" data-bound = "item.key1" & gt; & lt; / td & gt; & Lt; Td square = "number1" data-bound = "item .key2" & gt; & Lt; / Td> & Lt; Td square = "number2" data-bind = "item .key3" & gt; & Lt; / Td> & Lt; / TR & gt;   
 (My experience is that you have to be careful with non-string in the domes when they

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...
