    मेरे पास इस तरह के कुछ कोड उदाहरण हैं

    --------------- ------- पहले उदाहरण ----------------- 

      var सही कार्य = समारोह () {if (options.currentPage & lt; Options.numberOfPages) {options.currentPage + = 1; ajaxConnection (); } विवरण झूठा है; }; $ ('# न्यूज़ कॉन्टैनेयर # राइटस्लिडर')। क्लिक करें (दाएं फंक्शन); । $ ( '# RightSliderHigh') पर क्लिक करें (rightFunction);   
     ---------------------- दूसरा उदाहरण --------------- ----  
      $ ( '# rightSliderPagination') पर क्लिक करें (function () {अगर (parseInt (_pagina_last_link.html ()) & gt;। = options.numberOfPages) {return false;} _first_page_num = parseInt (_pagina_first_link.html ()); paginationGenerator (_first_page_num + options.centerNumber - 1); $ ( '# स्लाइडर-भीतरी') स्लाइडर ( "विकल्प", "मूल्य", _first_page_num + options.centerNumber - 1)। ; विवरण झूठा है; });   
     ------------------------ तीसरे उदाहरण ------------- ---------  
      $ ("। डाउनलोड")। क्लिक करें (फ़ंक्शन () {if ($ (this) .attr ('goToPage') == 'true ') {Var url = $ (this) .attr (' href '); document.location.href = url; वापसी वापस;} var _this = $ (this); var thistext = $ ("# bg- डाउनलोड-बॉक्स ") .html (); वर _whattoshow = $ (this) .parent () (पाते हैं।" क्या करने के लिए शो। ") एचटीएमएल ();। अगर (_whattoshow) {$ (" # bg-डाउनलोड बॉक्स प्रपत्र ") .html (_whattoshow);} else {$ (" # bg-डाउनलोड-बॉक्स ") एचटीएमएल (।" & lt; div id = 'bg-डाउनलोड-बॉक्स भीतरी' शैली = 'ऊंचाई: 132px' & gt; & lt ; / div & gt; ");} अगर ($ (" की सिफारिश बॉक्स। ") # rightColumn") सीएसएस (। "z- सूचकांक लंबाई = 0) {$ (।!" ", 99999);} $ (" # bg-डाउनलोड-बॉक्स ") शो ();। वर whattocopy = $ (" # bg-डाउनलोड-बॉक्स "); $ (whattocopy) .insertAfter (केवल इस); $ ("। उल # गीत-सूची ") सीएसएस ( "Z-index", "99999"); $ ("ul # गाने-सूची li.bar")। RemoveClass ("emph"); $ (यह)। Parent ()। Parent ()। Parent ()। AddClass ("एएमएफपी"); वापसी झूठी;});   
     
     इन फंक्शंस के अंत में लौटाए जाने वाले फर्स्ट का इस्तेमाल क्यों किया जाता है? कृपया, किसी व्यक्ति को वापसी के उद्देश्य की व्याख्या हो सकती है।   
     
     
     उदाहरणों में 2 & amp; 3, पहले वापसी झूठी फ़ंक्शन में किसी भी आगे कोड के निष्पादन को रोका जा रहा है।  
     उदाहरण 1 में, यह वास्तव में कुछ भी नहीं करता है कभी-कभी मैं खुद को यह करता हूं, भविष्य में प्रोग्रामर के लिए आदत और स्पष्टता की वजह से जो मेरे कोड को पढ़ते हैं।

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...

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...

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...
