| 方法 | 定义对象 | |
|---|---|---|
CellSelectionModel(Object config) |
CellSelectionModel | |
addEvents(Object object) : void |
Observable | |
| 将对象中没有的事件从给出的对象中复制过来。 | ||
addListener(String eventName, Function handler, [Object scope], [Object options]) : void |
Observable | |
| 为该组件加入事件处理器函数 | ||
| clearSelections() : void | CellSelectionModel | |
| Clears all selections. | ||
fireEvent(String eventName, Object... args) : Boolean |
Observable | |
| 触发指定的事件, 并将参数传入(至少要有事件名称)。 | ||
hasListener(String eventName) : Boolean |
Observable | |
| 检查该对象是否拥有指定事件的侦听器 | ||
| hasSelection() : Boolean | CellSelectionModel | |
| Returns True if there is a selection. | ||
| isLocked() : Boolean | AbstractSelectionModel | |
| Returns true if the selections are locked | ||
| lock() : void | AbstractSelectionModel | |
| Lock the selections | ||
on(String eventName, Function handler, [Object options]) : void |
Observable | |
| 为该组件加入事件处理器函数, addListener 的简写方式 | ||
| purgeListeners() : void | Observable | |
| 从对象身上移除所有的侦听器 | ||
removeListener(String eventName, Function handler, [Object scope]) : void |
Observable | |
| 移除侦听器 | ||
select(Number rowIndex, Number collIndex) : void |
CellSelectionModel | |
| Selects a cell. | ||
un(String eventName, Function handler, [Object scope]) : void |
Observable | |
| 移除侦听器, removeListener 的简写方式 | ||
| unlock() : void | AbstractSelectionModel | |
| Unlock the selections | ||
| 事件 | 定义对象 | |
|---|---|---|
beforerowselect : (SelectionModel this, Number rowIndex, Number colIndex) |
CellSelectionModel | |
| Fires before a cell is selected. | ||
cellselect : (SelectionModel this, Number rowIndex, Number colIndex) |
CellSelectionModel | |
| Fires when a cell is selected. | ||
selectionchange : (SelectionModel this, Object selection) |
CellSelectionModel | |
| Fires when the active selection changes. | ||

组合选项
使用选项参数可以组合不同类型的监听器:
下面是一个标准的、延迟执行的、一次性的监听器,将会自动停止事件并传递一个自定义的参数(forumId)
el.on('click', this.onClick, this, { single: true, delay: 100, stopEvent : true, forumId: 4 }); 这个方法也允许传递的单个参数是一个包含多个指定处理函数的设置对象。
一次调用多个处理函数
代码:
el.on({ 'click' : { fn: this.onClick scope: this, delay: 100 }, 'mouseover' : { fn: this.onMouseOver scope: this }, 'mouseout' : { fn: this.onMouseOut scope: this } }); 或者简写为:
代码:
el.on({ 'click' : this.onClick, 'mouseover' : this.onMouseOver, 'mouseout' : this.onMouseOut scope: this });
