javascript - getting wrong target object in ng-click -


html कोड 

  & lt; div ng- click = "sortOrder ($ event, पूर्णनाम ') "वर्ग =" कर्नल- xs-2 sortable asc "& gt; & LT; अवधि & gt; नाम से & lt; / span & gt; & Lt; / div & gt;   
 यहां जेएस कोड है  
  $ scope.sortOrder = function (ईवेंट, नाम) {var $ elem = $ (event.target); var c = $ elem.hasClass ('desc')? 'एसीसी': 'एड्स'; $ Elem.removeClass ('asc desc')। AddClass (सी); } 
 
 
 
  
 
  
 
 टेक्स्ट "itemprop =" text "> 
 इसके बजाय  currentTarget  का उपयोग करें:  
  var $ elem = $ (event.currentTarget);   
 वर्तमान लक्ष्य पर ईवेंट श्रोता बनने वाला तत्व है, लक्ष्य तत्व को ट्रिगर करने वाला तत्व है।  
 इसका अर्थ है कि यदि आप अवधि  लक्ष्य  अवधि होगी और यदि आप div पर क्लिक करेंगे तो  लक्ष्य  div हो जाएगा लेकिन दोनों मामलों में  currentTarget  div हो जाएगा।  
 एक और आसान समाधान के बजाय  ng-class  का उपयोग करना है।  
 HTML :  
  & lt; div ng-click = "changeSortOrder ()" class = "col-xs-2 sortable" एनजी-वर्ग = "सॉर्ट ओर्डर" & gt; & LT; अवधि & gt; नाम से & lt; / span & gt; & Lt; / div & gt;   
 जेएस:  
  $ scope.sortOrder = 'asc'; $ scope.changeSortOrder = फ़ंक्शन () {$ scope.sortOrder = $ scope.sortOrder === 'एस्क'? 'Desc': 'एसीसी'; };   
  डेमो :  
 आपके तर्क के साथ उदाहरण निर्देश में चला गया:  
 जेएस:  
  एप दि डायरेक्टिव ('माइसोर्ट', फंक्शन () {रिटर्न: स्कोप: सच्चा, लिंक: फंक्शन (स्कोप, एलीमेंट) {var डिफ़ॉल्टSortOrder = 'asc'; element.addClass (defaultSortOrder); var परिवर्तनसॉर्टऑर्डर = फ़ंक्शन ) {Var newOrder = element.hasClass ('asc')? 'Desc': 'asc'; element.removeClass ('asc desc')। AddClass (नया ऑर्डर);}; element.on ('click', changeSortOrder); दायरा। $ ('$ नष्ट', फ़ंक्शन () {element.off ('click', changeSortOrder);});}}});   
 HTML:  
  & lt; div class = "col-xs-2 sortable" my-sort & gt; & Lt; span & gt; तत्व 1 & lt; / span & gt; & Lt; / div & gt; & Lt; div class = "col-xs-2 sortable" my-sort & gt; & Lt; span & gt; एलिमेंट 2 & lt; / span & gt; & Lt; / div & gt; & Lt; div class = "col-xs-2 sortable" my-sort & gt; & Lt; span & gt; तत्व 3 & lt; / span & gt; & Lt; / div & gt;   
  डेमो :

How can I add a seperate action listener to all 14 of my buttons at once that can determine player turn?(java) -

I have a big code, for a game I'm calling Tommy's Kumamak. I know that this is not beautiful, but I am very naive and for some reasons I know from using arrays, anyway, my problem is that I can not add a variable outside the listener and within the action listener I can modify the variable (pTurn ++) from How can I go about adding a count to that variable from inside the action listener? 1 error was found: file: c: \ user \ public \ togiz_kumalak.java [line: 130] error: local variables pTurn is accessed from within internal class; Need to be declared final int pTurn = 0; Button1.addActionListener {new zero-action action (action event e) {pTurn ++; if (pTurn% 2 == 0) {display.append ("\ n Player 2 cup 1");} If ( PTurn% 2! = 0) {display.append ("\ nPlayer 1Cup 1")}}); In that case, move the contents of the functionalities into orbit and then call the action For example, display the method from: Private Zero Button Press {pTurn ++; If (pTurn% 2...
