How to get value from the Store by id?

此类领域的储存

    fields: [
    {name: "id", type:  int },
    {name: "name", type:  String },...

我们需要获得id- > 姓名/em> 价值。

I try so:

var rec = Ext.StoreMgr.lookup("MyStore").getById(id); alert(rec.data.name);

我做了什么错误?

Answer 1

The function getById finds the record with the specified id which has nothing to do to with the id you specified in the fields config - Basically you re looking at record.id while you should be looking at record.data.id.

3.3.1 应使用:

var index = Ext.StoreMgr.lookup("MyStore").findExact( id ,id);
var rec = Ext.StoreMgr.lookup("MyStore").getAt(index);
