how sencha dynamic add tab in tabpanel,and add list to the tabpanel

Question

i want to build a framework that dynamic. first, add "loanname" to be my title in tab to add to a tabpanel. second, dynamic add my product which the loanname measure the tab title's loanname.

the loanname in json be the title which i want to be the title on everytab:

{
"listjson" : [
    {"loanname" : "xixi22" , "loandesc" : "use to architecture"},
    {"loanname" : "xixi2" , "loandesc" : "use to education"},
    {"loanname" : "xixi3" , "loandesc" : "use to plane and others"}
]
}

and the product which i want put it in list(a list contain the same loanname product), then put the list into the match tab:

{
"products" :[
    {"loanname": "xixi22", "loannum": "A-0000001", "interests": "6.5", "timeline": "1 year"},
    {"loanname": "xixi22", "loannum": "A-0000002", "interests": "7", "timeline": "2 year"},
    {"loanname": "xixi2", "loannum": "B-0000001", "interests": "9", "timeline": "3 year"},
    {"loanname": "xixi3", "loannum": "C-0000001", "interests": "11.5", "timeline": "4 year"}
]
}

the result view i want is similiar like under: but i have encounter a problem the list contain the other product which not match the loanname in title and display for null

-------------edit part--------- my part code in view:

        {
            xtype: 'tabpanel',
            itemId: 'tabfirst',
            flex: 1,
            //activeItem: 1,
            tabBar: {
                layout: {
                    pack: 'center'
                }
            },
            defaultType: 'tablist'
        }

the list view:

Ext.define('ylp2p.view.tablist',{
extend: 'Ext.dataview.List',
xtype: 'tablist',
config: {
    title: '',
    store: 'productstore',
    itemTpl: '{loanname}'
}
});

my code in controller:

Ext.define('ylp2p.controller.addtab',{
extend: 'Ext.app.Controller',

config: {
    refs: {
        myTabPanel: '.makemoney #tabfirst',
    },
    controller: {
        myTabPanel: {
            activate: 'OnActivateTabPanel',
            activateitemchange: 'OnActivateItemChangeTabPanel'
        }
    }
},
launch: function(){
    var products = Ext.getStore('productstore');

    products.filterBy(function(record, id){
       return record.get('loanname') === 'xixi22';
    });
},

OnActiveTabPanel: function(newActiveItem, viewport, oldActiveItem, eOpts){
    var tabs = Ext.getStore('loanliststore');

    tabs.each(function(record){
        newActiveItem.add({
            title: record.get('loanname')
        });
    });
},

OnActiveItemChangeTabPanel: function(cmp, value, oldValue, eOpts){
    var products = value.getStore();

    products.clearFilter(true);
    products.filterBy(function(record, id) {
        return record.get('loanname') === value.getTitle();
    });
}

});

my store:1.tab store loanlist.js,2.product store prostore.js

Ext.define('ylp2p.store.loanlist',{
extend: 'Ext.data.Store',
config:{
    model: 'ylp2p.model.list',
    storeId: 'loanliststore',
    autoload: true,
    proxy: {
        type: 'ajax',
        url: 'resources/json/loanlist.json',
        reader:{
            type: 'json',
            rootProperty: 'listjson'
        }
    }
}
});

and

Ext.define('ylp2p.store.prostore',{
extend: 'Ext.data.Store',
config: {
    model: 'ylp2p.model.loanproduct',
    storeId: 'productstore',
    autoload: true,
    proxy: {
        type: 'ajax',
        url: 'resources/json/product.json',
        reader: {
            type: 'json',
            rootProperty: 'products'
        }
    }
}
});

app.js:

Ext.application({

    Ext.getStore('productstore').load();
    console.log('start Big weapon!!here is app.js launch function');       

onUpdated: function() {
    Ext.Msg.confirm(
        "Application Update",
        "This application has just successfully been updated to the latest version. Reload now?",
        function(buttonId) {
            if (buttonId === 'yes') {
                window.location.reload();
            }
        }
    );
}
});

Can you provide us the code which is responsible for filtering the data based on the title? In other words, what is causing the null values? — Tarabass, Sep 18 '15 at 18:20

Use this code. It will work.

var items = [];
        var store = Ext.getStore('YourStore'); // write your store here
        var loanname = record.get('loanname');
        store.each(function (r) {
            if (r.get('loanname') == loanname) {
                items.push(r.data);
            }
        });
        var myPanel = Ext.create('Ext.List', {
            title: 'loanname',
            data: items,
            itemTpl: '{loannum}'
        });
        moneytab.add(myPanel);

You don't have to push all items to an array, and use that array as data on the list. Just set the store as store on the list and use `queryBy` to filter the items. A store is automatically one-way binded. All changes to the store are automatically binded to the list. – Tarabass Sep 18 '15 at 18:19

In the activeitemchange listener you can filter the store based on the title of the tab (activeitem). I quickly created a fiddle for you to show you how I would do it:

https://fiddle.sencha.com/#fiddle/u50

var tabs = Ext.create('Ext.data.Store', {
    fields: ['loanname', 'loandesc'],
    data: [
        {"loanname" : "xixi22" , "loandesc" : "use to architecture"},
        {"loanname" : "xixi2" , "loandesc" : "use to education"},
        {"loanname" : "xixi3" , "loandesc" : "use to plane and others"}
    ]
})

var products = Ext.create('Ext.data.Store', {
    fields: ['loanname','loannum','interests','timeline'],
    data: [
        {"loanname": "xixi22", "loannum": "A-0000001", "interests": "6.5", "timeline": "1 year"},
        {"loanname": "xixi22", "loannum": "A-0000002", "interests": "7", "timeline": "2 year"},
        {"loanname": "xixi2", "loannum": "B-0000001", "interests": "9", "timeline": "3 year"},
        {"loanname": "xixi3", "loannum": "C-0000001", "interests": "11.5", "timeline": "4 year"}
    ]
});

Ext.define('Fiddle.view.MyList', {
    extend: 'Ext.dataview.List',
    xtype: 'mylist',

    config: {
        title: '', // We have to config a title to let the framework generate getters and setters
        store: products,
        itemTpl: '{loannum}'
    }
});

Ext.application({
    name : 'Fiddle',


    launch : function() {
        var tabPanel = Ext.create('Ext.TabPanel', {
            fullscreen: true,
            defaultType: 'mylist',
            items: [],
            listeners: {
                activate: function( newActiveItem, viewport, oldActiveItem, eOpts) {
                    products.filterBy(function(record, id) {
                        return record.get('loanname') === 'xixi22';
                    });
                },
                activeitemchange: function( cmp, value, oldValue, eOpts ) {
                    products.clearFilter(true);
                    products.filterBy(function(record, id) {
                        return record.get('loanname') === value.getTitle();
                    });
                }
            }
        });

        tabs.each(function(record){
            tabPanel.add({
                title: record.get('loanname'),
                iconCls: 'home',
            });
        });
    }
});

hi!~~ i have a question in the fiddle:what's the mean of "type:products" in products store not the "storeId : products". and in my code above the "products" store in activate items cant get, so i use the getstore method. and now the trouble is the my view "tablist " cant getthe data.THX!~ — chen, Sep 21 '15 at 08:54
Forget the 'type' config. I was just messing around. I also greated this app with mvc structure. Hopefully it does help you with getting the products store etc. https://fiddle.sencha.com/#fiddle/u7c — Tarabass, Sep 21 '15 at 20:10
now both the tab and list cant display.and i have edit my question.is there something wrong in my MVC? — chen, Sep 22 '15 at 02:56
Are the filenames corresponding with your class names? Did you include the store, models, views and controllers in `app.js`? If you look in the Sencha App Inspector extension for Chrome, are your stores and views shown there? Any errors? — Tarabass, Sep 22 '15 at 06:17
1.yes, 2.yes, 3. show none,4.no errors. sencha is difficult! Ho-Ho! — chen, Sep 22 '15 at 06:50
Check your app.js, and compare it with mine (in the mvc fiddle). — Tarabass, Sep 22 '15 at 07:08
