JSON Nested List to Checkbox

[lab-24]

HI,

Is it possible to bind a nested array (the Roles in the following JSON) to checkboxes in a fieldset?

[
{
"name": "User 1",
"role": ["admin", "user", "partner"],
},
{
"name": "User 2",
"role": ["admin"],
}
]

Roles:
[ ] superuser
[x] admin
[x] user
[x] partner

Regards,
Marcel

You could create an ArrayStore and then use combo.store.loadData() to load the data.

Check out setValue for checkboxgroup:
http://docs.sencha.com/ext-js/4-0/#!...ethod-setValue

var form = ​Ext.widget('form', {
    width: 400
    , renderTo: Ext.getBody()
    , items: [{
        xtype: 'checkboxgroup'
        , defaults: { name: 'role' }
        , items: [{
            boxLabel: 'Superuser'
            , inputValue: 'superuser'
        }, {
            boxLabel: 'Admin'
            , inputValue: 'admin'
        }, {
            boxLabel: 'User'
            , inputValue: 'user'
        }, {
            boxLabel: 'Partner'
            , inputValue: 'partner'
        }]       
    }]
});


Ext.widget('button', {
    text: 'Set Values'
    , renderTo: Ext.getBody()
    , handler: function () {
        var boxes = form.down('checkboxgroup');
        var data = [{"name": "User 1","role": ["admin","user","partner"]},{"name": "User 2","role": ["admin"]}];
        boxes.setValue(data[0]);
    }
});
