Question

i’m working with couchdb as database.. i need show the data in pagination grid..
i can handle the next page proccess… but i am stack in how to handle previous page

after hard trying,… i can show previous json like this :

http://localhost/myapp/_view/getAll?limit=2&startkey=10&skip=1&descending=true
and the response :

{
    total_rows: 21,
    offset: 12,
    rows: [{
        id: "fd899e87f9f682a4df71d9e2a9010b26",
        key: 9,
        value: {
            _id: "fd899e87f9f682a4df71d9e2a9010b26",
            _rev: "1-ce4ed0e621ae53996f323a8927bcf470",
            $type: "siswa",
            Nama: "test9",
            Agama: "Islam",
            Hobi: ["Membaca","Menulis"]
        }
    } , {
        id: "fd899e87f9f682a4df71d9e2a9010622",
        key: 8,
        value: {
            _id: "fd899e87f9f682a4df71d9e2a9010622",
            _rev: "1-45c71654623d385bd95f6970c72dce50",
            $type: "siswa",
            Nama: "test8",
            Agama: "Islam",
            Hobi: ["Membaca","Menulis"]
        }
    }]
}

the shown data is in reverse format.
as you can see, the response json start with key 9, and then 8..
so, the solution is reverse back in extjs / UI..

how to reverse data from store in extjs 4 ?
in ext 3 i do that like this : this.store.reader.reversed = true; and then reload the store..

Answer 1

You can sort you store like this:

Ext.create('Ext.data.Store', {
        sorters: [
        {
            property : 'key',
            direction: 'ASC'
        }
        // ...
}

or call store.sort('key', 'ASC');
