Ich bastle seit Tagen an einer Groupinggrid mit Paging, Search, Exportfunktion, Inlineediting mit Roweditor, RSA Verschlüsslung und remote Sortierung auf alle Spalten.
Gleich ein wenig viel für den Anfang.
Also beschränke ich mich vorerst auf das Remotesorting, Grouping, RSA und eben das Paging.
Wichtig zu wissen ist hier:
Der JsonReader verarbeitet die wesentlichen Serverresponse-Values. Wie die Gesamtzahl(totalProperty) der Datensätze. “totalProperty” ist wichtig für das Paging. Ohne die Zahl werden die Navigationsbuttons nicht aktiviert und paging suxx.
root: ‘data’, Enthält die Daten zur Anwort. Ohne Daten kein View. Klar.
Die Response muss allso mindestens 3 JS-Objekte liefern. “totalCOunt, sort und data”.
Die Resonse zu der Grid mit 2 Datensätzen oben sieht also folgendermassen aus:
{ "totalCount":206, "sort":"company_name", "message":"ewqeqwewqe", "data":
[
{ "copyID":"227", "survey_name":"Mitarbeiterumfrage", "orga_name":"Trainer", "company_name":"Test23 AG", "created":"2009-06-16 19:19:13", "description":"Test" },
{ "copyID":"226", "survey_name":"Mitarbeiterumfrage2", "orga_name":"Trainer2", "company_name":"Test AG 22", "created":"2009-06-16 19:19:13", "description":"Test" },
] }
Groupstore: Beinahe noch wichtiger ist der Initialload der ersten page. Der Datastore wird beim Rendern mit der page 0 geladen
gridedtorstore.load({params:{start: 0, limit: 20}});
Der Code für die Grid dann so. Nicht über die RSA Sachen wundern. Die verschlüsslung ist hier Standar
var columnobjectsurvey = Ext.data.Record.create([{name: 'copyID',type: ''},{name: 'company_name',type: 'string'},{name: 'orga_name',type: 'string'},{name: 'created',type: 'string'},{name: 'description',type: 'string'},{name: 'survey_name',type: 'string'}]);
