ExtJs4 获取grid.panel中的被修改数据
var updateBtn=Ext.create('Ext.Button', {
text: '保存修改',
ionCls:"icon-edit",
handler: function(){
var _grid = Ext.getCmp("id_of_grid");
//我尝试了很多方法都获取不到
var m = _grid.getStore().getUpdatedRecords();
if(m.length == 0) {
Ext.MessageBox.alert("信息","没有任何记录被修改");
return;
}
var jsonArray = [];
Ext.each(m,function(item){
jsonArray.push(item.data);
alert(item.data);
});
Ext.Ajax.request({
method:'POST',
url:'user_update.action',
success:function(response) {
Ext.MessageBox.alert("信息",response.responseText,function(){
store.load();
store.modified = [];
});
},
failure:function(){
Ext.MessageBox.alert("错误","与后台联系的时候出了问题");
}
,
params:'data=' + Ext.encode(jsonArray)
});
}
});

[解决办法]
var _grid = Ext.getCmp("id_of_grid").getValue;
你的grid是个什么，是整个grid么？？
