Ext provides a straightforward means of accessing component objects by ID:

Ext.getCmp('time')

Also see the new component query : http://dev.sencha.com/deploy/ext-4.0-beta2/docs/api/Ext.ComponentQuery.html

You can then select the component via the "#id" selector.

There is also the possibility to find query in a components tree with cmp.query, cmp.down...

Assuming the following :-

  Ext.create('Ext.form.FormPanel', {
       **alias:'myFormPanel'**
        title: 'Task option',
        items:[
            {
              xtype: 'textfield',
              name: 'txt-test1',
              id: 'time',

you can use :- Ext.ComponentQuery.query('myFormPanel textfield[name=txt-test1]')
