Store in a function

[Madiyana]

Hi,
I am a new user in ExtJS4 and I have a problem that i can't resolve..
I wanna put in a function this code :

    
var storeLD01_Objet = Ext.create('Ext.data.Store', {
        fields      :['id', 'libelle'],
        labelWidth      :150,
        proxy: {
             type: 'ajax',                            
             url: '/value/TypeAmenrecherche/search',
             reader: {
                 type: 'json',
                 root: 'elt'
            }
        },
        listeners: {
            'load': function(store, operation, options){
                this.insert(0, {id:'--', libelle:'--'});                
            }
        },
     autoLoad: true
    });

My objective is to have a function like :
function loadstore(link){
...
url: '/gtrte/link/search',
...
} because I want have a dynamic store who change with my value "link"

loadstore: function (link) {
   this.getProxy ().url = 'foo' + link + 'bar';
   this.load ();
}

Is storeLD01_Objet a global variable? You are not providing any scope to the object.

[Madiyana]

Yes it is a global variable
