//keyPath:Javascript对象，对象必须有一属性作为键值
var store=db.createObjectStore('Notprint',{keyPath:"groupId"});
store.createIndex('buyerName','name',{unique:true});
}
}
}代码有些长， 就是我从后台拿过来的数据 传进来， 没有建索引的时候很正常 数据能正常存储进来，可是我一但建立了索引那么 if(!db.objectStoreNames.contains('Shipped')){
//keyPath:Javascript对象，对象必须有一属性作为键值
var store=db.createObjectStore('Shipped',{keyPath:"groupId"});
store.createIndex('buyerName','name',{unique:true});
}这个表里 包括索引里 都没有数据，调试也没有报错 ！ 来大神拯救
