arrays - loading data from a json -

-

i have data available want load this:

{ "success": true, "message": null, "total": null, "data": [{     "clocktypes": ["_12", "_24"],     "speedtypes": ["mph", "kmph"],     "scheduletypes": ["default", "auto"] }]}

i normaly load data this

ext.define('myapp.store.combotimezone', { extend: 'ext.data.store',  constructor: function(cfg) {     var me = this;     cfg = cfg || {};     me.callparent([ext.apply({         autoload: true,         storeid: 'myjsonstore5',         proxy: {             type: 'ajax',             url: 'json/timezone.json',             reader: {                 type: 'json',                 root: 'data'             }         }     }, cfg)]); }});

now clocktypes 1 record in combobox. how can 2 records: _12 , _24 in combobox?

your root should be... data.clocktypes -think- ( though i'm not sure if work. )

hijacking ajax call load data bit awkward, since thats not right format store consume( it? )

ideally want... 

{ "success": true, "message": null, "total": null, "data": [{    name: "_12", name:"_24"] }]}  constructor: function(cfg) { var me = this; cfg = cfg || {}; me.callparent([ext.apply({     autoload: true,     storeid: 'myjsonstore5',     valuefield:'name',     displayfield:'name',     proxy: {         type: 'ajax',         url: 'json/timezone.json',         reader: {             type: 'json',             root: 'data'         }     } }, cfg)]); }});

though mean end more ajax calls. alternatively, if you've got heart set on populating 3 comboboxes (i'm kinda guessing that's trying ) 1 ajax call, need generate stores dynamically based off data ext.request()

however if cant mess data, can...

    ext.define('myapp.store.combotimezone', {     extend: 'ext.data.store',      constructor: function(cfg) {         var me = this;         cfg = cfg || {};         ext.define('tz', extend: 'ext.data.model',         fields: [{             name: 'name'         }])         me.callparent([ext.apply({             autoload: true,             model: 'tz',             storeid: 'myjsonstore5',             proxy: {                 type: 'ajax',                 url: 'json/timezone.json',                 reader: {                     type: 'json',                     root: 'data'                 }             }         }, cfg)]);         //hacky, works guess         ext.ajax.request({             url: 'my.json',             success: function(response) {                 var text = response.responsetext;                 var json = ext.json.decode(text);                 for(var =0);i<json.data.lenght();i++;){                     ext.data.storemanager.lookup('myjsonstore5').add(ext.create('tz',{name:json.data[i]}))                 }             }         });     } });

*barrring typos create bugs.

basically call url, data raw json, , process format store can read.

it's bit of hack unfortunately.
