extjs4 grid 多选、添加复选框、动态添加删除数据

grid多选属性：multiSelect: true[b]添加[/b]复选框：首先定义var selectModel = Ext.create(‘Ext.selection.CheckboxModel’); 然后设置grid的selModel属性。动态[b]添加删除数据[/b]：store.insert();和store.remove();//示例代码：var arows = Ext.getCmp('dailytestuffASG').getSelectionModel().getSelection();var
orows = Ext.getCmp('dailytestuffOSG').getSelectionModel().getSelection();if(orows.length==0){Ext.Msg.alert('错误','请选择要[b]添加[/b]的记录！');return;}var flag = false;for(var i=0;i<orows.length;i++){if(arows.length>0){for(var j=0;j<arows.length;j++){
if(orows[i].get('userId')==arows[j].get('userId')){ flag = true; break; }}if(flag==true){ flag==false; continue;}}var data = [{'userId': orows[i].get('userId'), 'userName': orows[i].get('userName'), 'depart': orows[i].get('depart')}];dailytestuffASGStore.insert(0,data);}Ext.each(orows,function(orows){dailytestuffOSGStore.remove(orows);});dailyASGModel.selectAll();
