1.错误的写法:
js异常这样会导致view对象没有实例化
//加载品牌数据集,并给品牌下拉框赋初始值
brandStore.load({
params: {
date: Ext.util.Format.date(Ext.Date.add(new Date(),Ext.Date.MONTH, -1),"Ym"),//默认参数
},
callback: function(records, operation, success){
//获取grid的复选框对象
var selMod = brandGrid.getSelectionModel();
//默认选中10个品牌
for (var i = 0; i <10; i++){
selMod.select(i,true,false);
};
//打开品牌窗体
brandWindow.show();
}
});
2.正确的写法:
先打开窗体,然后操作窗体中grid对象的复选框
//加载品牌数据集,并给品牌下拉框赋初始值
brandStore.load({
params: {
date: Ext.util.Format.date(Ext.Date.add(new Date(),Ext.Date.MONTH, -1),"Ym"),//默认参数
},
callback: function(records, operation, success){
//打开品牌窗体
brandWindow.show();
//获取grid的复选框对象
var selMod = brandGrid.getSelectionModel();
//默认选中10个品牌
for (var i = 0; i <10; i++){
selMod.select(i,true,false);
};
}
});
