Ext JS 4.2分页组合-如何跳至页面

Question

I have a Combo such as:

{
        xtype : 'combo',
        anchor : '70%',
        id : 'companyCombo',
        fieldLabel : 'Company',
        name : 'COMPANY_ID',
        store: companyStore,
        pageSize: 25,
        displayField : 'COMPANYNAME',
        valueField : 'COMPANY_ID',
        typeAhead : true,
        queryMode : 'local',
        forceSelection : true,
        allowBlank : false,
        editable : true
},

When using a paging Combo Box with Ajax data, I am advised to first determine (via Ajax) which 'page' the current item is on, and then set the Combo's page to that via:

pagingtoolbar.move(pageNumber)

The problem is, I'm not sure how to get a reference to pagingtoolbar for the Combo. It doesn't seem to correspond to any of the member fields of the object returned via Ext.getCmp('companyCombo') ...

Answer 1

The toolbar is on the combo's picker, not the combo itself. Try this:

var combo   = Ext.getCmp('companyCombo'),
    toolbar = combo.getPicker().pagingToolbar;
