Cocos2d-JS项目之二：studio基础控件的使用

 

在studio里把几个基础控件往场景文件一拖，然后导出json格式的资源文件

 

逻辑代码如下：

  1 var HelloWorldLayer = cc.Layer.extend({
  2     sprite:null,
  3     value : 90,
  4    // self : this,
  5     ctor:function () {
  6         //////////////////////////////
  7         // 1. super init first
  8         this._super();
  9 
 10         /////////////////////////////
 11         // 2. add a menu item with "X" image, which is clicked to quit the program
 12         //    you may modify it.
 13         // ask the window size
 14         var size = cc.winSize;
 15 
 16         this.initUI();
 17 
 18         return true;
 19     },
 20 
 21     //init ui
 22     initUI : function(){
 23         var mainscene = ccs.load(res.MainScene_json);
 24         this.addChild(mainscene.node);
 25 
 26         var self = this;
 27         //   btn.addClickEventListener(this.btnClick);
 28         //   addTouchEventListener(this.backEvent,this);
 29 
 30         var btn = ccui.helper.seekWidgetByName(mainscene.node, "Button_9");
 31         btn.addClickEventListener(function(){
 32                 cc.log("btn_9 click: %d", self.value);
 33             });
 34 
 35 
 36         var checkBox = ccui.helper.seekWidgetByName(mainscene.node, "CheckBox_2");
 37         this.checkBox = checkBox;
 38         checkBox.addEventListener(this.selectedStateEvent, this);
 39 
 40         //slider addClickEventListener、addTouchEventListener 事件在鼠标松开时才触发 //
 41         // addEventListener 在按住并有移动时（值不一定有改变）就触发 //
 42         var slider = ccui.helper.seekWidgetByName(mainscene.node, "Slider_2");
 43         this.slider = slider;
 44         slider.addClickEventListener(function(){
 45             var percent = slider.getPercent();
 46             cc.log("addClickEventListener   %d", percent);
 47         });
 48 
 49         slider.addTouchEventListener(function(){
 50             var percent = slider.getPercent();
 51             cc.log("addTouchEventListener   %d", percent);
 52         });
 53
