关于cocos2d-JS开发看过两本书，《Cocos2d-JS开发之旅》和《Cocos2d-x实战-JS卷》，两本书都不错，各有特点，但是在实际开发中，有很多关于常用的控件这两本书并没有详细的阐述，因此，在接下来的开发中，我会把一些常用的控件，比如TableView和CollectionView之类的使用技巧和说明，会不断更新在此文章中。
1、Cocos Studio ListView 控件监听
if(!cc.Layer.prototype.init.call(this))
{
return false;
}
var objView = ccs.csLoader.createNode(res.StageInfo_Json);
this.addChild(objView);
this._tableViewItem1 = ccui.helper.seekWidgetByName(objView,"Tablelist_Item1");
this._tableViewItem1.setScrollBarEnabled(false);
this._tableViewItem1.addEventListener(this.onSelectedItemEvent.bind(this),this);
this._tableViewItem2 = ccui.helper.seekWidgetByName(objView,"Tablelist_Item2");
this._tableViewItem2.setScrollBarEnabled(false);
this._tableViewItem2.addEventListener(this.onSelectedItemEvent.bind(this),this);
onSelectedItemEvent: function (sender,type) {
switch (type)
{
case ccui.ListView.EVENT_SELECTED_ITEM:
break;
case ccui.ListView.ON_SELECTED_ITEM_END:
// alert(sender.getName() + " " + sender.getCurSelectedIndex());
this.showDetail(sender.getCurSelectedIndex());
break;
default:
break;
}
}
说明：很多时候使用Cocos Studio工具生成的控件，仅仅使用一个坐标而已。
var listView = ccui.helper.seekWidgetByName(objView,"Tablelist");
listView.setScrollBarEnabled(false);
this._tableView = new cc.TableView(this,listView.getContentSize());
this._tableView.x = listView.x;
this._tableView.y = listView.y;
this._tableView.setDelegate(this);
this.addChild(this._tableView);
numberOfCellsInTableView: function (table)
{
return this._players.length;
},tableCellSizeForIndex: function (table,idx)
{
return this._cellSize;
},tableCellAtIndex: function (table,idx)
{
var att = this._players[idx];
var cell = table.dequeueCell();
if(cell == null)
{
cell = new FightListCell();
}
cell._player = att;
cell._labelName.setString(att.Name);
cell._labelFight.setString("战斗力:" + DataManager.getNumberText(att.Fight));
cell._labelReward.setString(DataManager.getNumberText(att.PresentRes.Amount));
cell._TGAmount = this._res.TGAmount;
cell._res = this._res;
var url = NetProxy.HostBaseUrl + att.IconId;
cell._imgIcon.setScale(0.8);
DataManager.loadUrlImage(url,cell._imgIcon);
var sprite = cc.Sprite.create("res/gui/PlayerBox.png");
sprite.setPosition(cell._imgIcon.getPosition());
cell.addChild(sprite);
return cell;
},tableCellTouched:function (table,cell)
{
}
如果需要多行多列显示，那么就得用CollectionView了：
var listView = ccui.helper.seekWidgetByName(objView,"Tablelist");
listView.setScrollBarEnabled(false);
this.m_tableView = new cc.CollectionView(this,cc.size(listView.getContentSize().width,listView.getContentSize().height));
this.m_tableView.setDirection(cc.SCROLLVIEW_DIRECTION_VERTICAL);
this.m_tableView.x = listView.getPositionX();
this.m_tableView.y = listView.getPositionY();
this.m_tableView.setDelegate(this);
this.addChild(this.m_tableView);
tableCellSizeForIndex: function (table,idx) {
if(this.m_type == 3 && (idx > this.m_flag-5 && idx <= this.m_flag))
{
return cc.size(110,25);
}
return this.m_cellSize;
},numberOfCellsInTableView: function () {
if(!this.m_items){
return 0;
}
return this.m_items.length;
},cellSizeForTable: function (table) {
// return table.getContentSize();
return cc.size(580,130);
},idx) {
var itemAtt = this.m_items[idx];
var cell = null;
// var cell = table.dequeueCell();
if(!cell){
cell = new InventoryCell();
}
cell.m_inventory = itemAtt;
if(itemAtt.Id != 0){ //空行的Id==0
var pic = "";
if(this.m_type == 1)
{
cell.m_level.setString("Lv." + itemAtt.Level);
pic = "res/pic/Equip/" + itemAtt.IconId + ".png";
}
else if(this.m_type == 2)
{
cell.m_level.setString(itemAtt.Amount);
pic = "res/pic/Gems/" + itemAtt.IconId + ".png";
}
else if(this.m_type == 3)
{
if(idx < this.m_gemsNoEquip.length)
{
cell.m_level.setString(itemAtt.Amount);
}
else
{
cell.m_level.setString(itemAtt.EqpAmount);
}
pic = "res/pic/Gems/" + itemAtt.IconId + ".png";
}
else if(this.m_type == 4)
{
cell.m_level.setString(itemAtt.Amount);
pic = "res/pic/Gems/" + itemAtt.IconId + ".png";
}
}
else
{
if(idx == this.m_flag-4)
{
cell = new CombatCell();
cell._Time.setVisible(false);
cell._Info.setString(" ------已装备宝石------")
}
else
{
cell.m_level.setVisible(false);
cell.m_image.setVisible(false);
// cell.m_Box.setVisible(false);
}
return cell;
}
// this.changeNodeTexture2(pic,"image_Equipment",cell);
this.createImage2(this.createIcon(itemAtt.IconId),cell);
return cell;
},tableCellTouched: function (table,cell) {
if(cell.m_inventory.Id != 0){
if(this.m_type == 1)
{
// SceneManager.addLayer(cc.LAYER_EQUIPUI,cell.m_inventory);
var ui = SceneManager.addLayer(cc.LAYER_EQUIPUI,null,true,cc.LAYER_ANI_NONE,true);
if (ui)
{
//替换装备与装备相关操作
ui.initEquipUI(null,cell.m_inventory);
}
}
else if(this.m_type == 3)
{
SceneManager.addLayer(cc.LAYER_GEMINFO,cell.m_inventory);
}
else
{
SceneManager.addLayer(cc.LAYER_ITEMINFO,cell.m_inventory);
}
}
}
CollectionView比TableView需要多实现一个方法，CellSizeForTable return table.getContentSize(); 但这样写，我这里出现bug，刷新列表时，即
this.m_tableView.reloadData()，会出现所有行都重叠到第一行中的bug，debug发现table.getContentSize的值为（0,0）所致。所以索性直接传入 return cc.size(580,130);
2、TableView实现可拖动的地图
/**
*世界地图
*/
WorldMapCell = cc.TableViewCell.extend({
_btnStage: [],_imgPath: [],_wordMap: null,_imgPosition: null,ctor: function () {
this._super();
this.init();
},init: function () {
this._super();
var cell = ccs.csLoader.createNode(res.WorldMapCell_Json);
this.addChild(cell);
for(var i = 0; i < 30; i++)
{
this._btnStage[i] = ccui.helper.seekWidgetByName(cell,"btnStage" + (i+1));
this._btnStage[i].setVisible(false);
this._btnStage[i].addTouchEventListener(this.onButtonClick,this);
if(i < 29)
{
this._imgPath[i] = ccui.helper.seekWidgetByName(cell,"WorldMap_Path" + (i+1));
this._imgPath[i].setVisible(false);
}
}
this._imgPosition = ccui.helper.seekWidgetByName(cell,"PlayerMarker");
this._imgPosition.setScale(0.4);
return true;
},onButtonClick: function (sender,type) {
switch (type)
{
case ccui.Widget.TOUCH_ENDED:
if(sender.getName().substr(0,8) == "btnStage")
{
SceneManager.addLayer(cc.LAYER_STAGEINFO,sender.getName().substr(8));
}
break;
default:
break;
}
}
})
WorldMapUI = BaseUI.extend({
_Prompt0:null,_Prompt1:null,_TCoinNum:null,_labelSweep:null,_size: null,_cellSize: null,_worldMap1: null,_worldMap2: null,_worldMap3: null,_scrollView: null,_btnExit: null,_btnAdd: null,_layer: null,_dots: null,_listener: null,ctor:function() {
this._super();
this._dots = new Array();
var cell = ccs.csLoader.createNode(res.WorldMapCell_Json);
this._cellSize = cell.getContentSize();
var Main= ccs.csLoader.createNode(res.WorldMapUI_Json);
this.addChild(Main);
this._size = cc.director.getWinSize();
this._btnExit = ccui.helper.seekWidgetByName(Main,"btnReturn");
this._btnExit.addTouchEventListener(this.onMainMenuClick,this);
this._btnAdd = ccui.helper.seekWidgetByName(Main,"btnAdd00");
this._btnAdd.addTouchEventListener(this.onMainMenuClick,this);
this._labelSweep = ccui.helper.seekWidgetByName(Main,"label_NuSweep");
this._scrollView = ccui.helper.seekWidgetByName(Main,"Tablelist_WorldMap");
this._scrollView.setScrollBarEnabled(false);
this._scrollView.setDirection(ccui.ScrollView.DIR_BOTH);
this._scrollView.setInnerContainerSize(cell.getContentSize());
this._scrollView.setInertiaScrollEnabled(true);
var item = new ccui.Layout();
// var cell = ccs.csLoader.createNode(res.WorldMapCell_Json);
var cell = new WorldMapCell();
cell._wordMap = this;
item.setContentSize(cell.getContentSize());
// var currentPveBig = DataManager.playerAtt.PveId;
var currentPveBig = 1;
var currentPve = 3;
this.getCellPoints(cell._btnStage,currentPveBig);
for(var i = 0; i < this._dots.length - currentPve; i ++)
{
cell.addChild(this._dots[i]);
}
for(var i = 0; i < currentPveBig; i++)
{
cell._btnStage[i].setVisible(true);
if(i < currentPveBig-1){
cell._imgPath[i].setVisible(true);
}
}
cell._imgPosition.setPosition(this._dots[this._dots.length - currentPve].getPosition());
item.addChild(cell);
this._scrollView.addChild(item);
},bindData:function(json)
{
return true;
},onMainMenuClick:function(sender,type) {
switch (type)
{
case ccui.Widget.TOUCH_ENDED:
if (sender.getName() == "btnReturn")
{
SceneManager.removeLayer(cc.LAYER_WORLDMAP);
}
else if (sender.getName() == "btnAdd00")
{
alert("购买扫荡次数");
}
break;
default:
break;
}
},getCellPoints: function (btns,index) {
for(var i = 0; i < btns.length - 1; i++)
{
if(i >= index)
{
break;
}
this.createDot(btns[i].getPositionX(),btns[i].getPositionY(),btns[i+1].getPositionX(),btns[i+1].getPositionY());
}
},createDot: function (x1,y1,x2,y2) {
var xA = (x2-x1)/6;
var yA = (y2-y1)/6;
for(var i = 0; i < 5; i++)
{
var dot = new cc.Sprite("res/gui/WorldMap_pic04.png");
dot.x = x1 += xA;
dot.y = y1 += yA;
this._dots.push(dot);
}
},});
WorldMapUI.create = function() {
return new WorldMapUI();
};
3、特效播放
/**

*/
DrawUI = BaseUI.extend({
m_size: null,m_confirm: null,m_drawAgain: null,m_img: null,m_name: null,m_type: null,//抽卡类型：1，免费单抽；2，免费十连；3，钻石单抽；4、钻石十连

}
this.m_size = cc.director.getWinSize();
var drawDode = new cc.DrawNode();
this.addChild(drawDode);
drawDode.drawRect(cc.p(0,0),cc.p(this.m_size.width,this.m_size.height),cc.color(0,210));
var objView = ccs.csLoader.createNode(res.DrawUI_Json);

this.m_btnItem = ccui.helper.seekWidgetByName(objView,"btnItem");
this.m_confirm.addTouchEventListener(this.onButtonClick,this);
this.m_drawAgain.addTouchEventListener(this.onButtonClick,this);
this.m_btnItem.addTouchEventListener(this.onButtonClick,this);
this.hideWidget();
return true;
},bindData: function (type) {
this.m_type = type;
if(type == 1)
{
ShopApi.Lottery(1,this,this.callbackLottery);
}
else
{
ShopApi.Lottery(3,this.callbackLottery);
}
