Is it possible to set a mask on a textfield in ST2 ?

{
    xtype: 'textfield',
    name: 'phonenumber',
    label: 'Your phone number',
    mask: '(999) 999-9999'
},

Works in Ext but not in ST, I ‘thought’ ST was built on top of Ext

    There’s no direct property in Sencha Touch that will do this job.

    So, you may need to do something like this ..

    {
    xtype: 'textfield',
    name: 'phonenumber',
    label: 'Your phone number',
    placeHolder: '(999) 999-9999',
    listeners : {
      keyup : function( ) {
        // Code that checks the i/p value according to placeHolder goes here ...
      } 
    }
},

    Btw, there’s one post on Sencha Touch forum.

    Hope that helps you!
