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);
},
tableCellAtIndex: function (table, 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), "image_Equipment", 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
/**

*/
WorldMapCell = cc.TableViewCell.extend({
_btnStage: [],
_imgPath: [],
_wordMap: null,
_imgPosition: null,
ctor: function () {

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;
}
}
})

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._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();
};
