How to add/remove entry related to a store.

[Thierryg]

Hi,

I have a list feed by a store from a local json.

I wanna know how to remove an entry from my store. Because it is feed by a json file, does it will update the json ? and once the json is update how to refresh/synchronize my list ?

Same question for adding one entry, in the json file, then refreshing the list.

Here is the source code i am using for creating the store :

        // -----------------------------------------
        // ----- Create a live profile's store -----
        // -----------------------------------------
        Ext.define('LiveProfileModel',
        {
            extend: 'Ext.data.Model',
            config:
            {
                fields:
                [
                    { name: 'id',    type: 'int'    },
                    { name: 'name',  type: 'string' },
                    { name: 'delay', type: 'int'    }
                ]
            }
        });
        LiveProfileStore = Ext.create('Ext.data.Store', { model: 'LiveProfileModel' });
        LiveProfileStore.setData(dmngConfig.liveProfile);

And the code need for the list :

{
                    title: 'LstLive',
                    layout: 'vbox',
                    padding: 10,
                    items:
                    [
                        {
                            title:   _strings_live_liveprofilelisting[dmngConfig.deviceLanguageID],
                            xtype:   'list',
                            itemTpl: '{name} (delay:{delay})',
                            store:   LiveProfileStore,
                            listeners:
                            {
                                itemtap: function(record, index)
                                {               
                                    //console.log("record="+record+" - index="+index);
                                    //console.log(record);
                                    console.log("[LIVE] id="    + dmngConfig.liveProfile[index].id);
                                    console.log("[LIVE] name="  + dmngConfig.liveProfile[index].name);
                                    console.log("[LIVE] delay=" + dmngConfig.liveProfile[index].delay);
                                    localStorage['liveprofileid']    = dmngConfig.liveProfile[index].id;
                                    localStorage['liveprofilename']  = dmngConfig.liveProfile[index].name;
                                    localStorage['liveprofiledelay'] = dmngConfig.liveProfile[index].delay;
                                    liveview.push(2);
                                }
                            }
                        }
                    ]
                }

Thanks in advance.

You shouldn't access localStorage directly, use the Store methods instead.

Most importantly, add/remove.
