一个蛮二的sencha-touch-toggle控件

单独用确实比较二，需要放在fieldset进行使用。

xtype: 'togglefield',name: 'toggleName',label: 'My Toggle Field',listeners: {beforechange: function (slider, thumb, newValue, oldValue) {if (oldValue == 0 && newValue == 1) {// Changing from off to on...validate something?}},change: function (slider, thumb, newValue, oldValue) {if (oldValue == 0 && newValue == 1) {// Changing from off to on...do something?}else if (oldValue == 1 && newValue == 0){// Changing from on to off...do something?}}            }
