javascript - How to disable a particular row in Picker in Sencha touch -


i have created picker in sencha touch 2.1. data displaying properly. want disable particular value not if select value , click "donebutton" shouldn't taken.

example:

function loadpicker(paramname, valueset) {     ext.viewport.remove(ext.getcmp(paramname + 'pickerfield'), true);     if (!paramname.picker) {         paramname.picker = ext.viewport.add({             xtype: 'picker',             id: paramname + 'pickerfield',             usetitles: true,             slots: [{                 name: paramname,                 title: paramname,                 data: valueset             }],              donebutton: {                 listeners: {                     tap: function(button, event, eopts) {                         var selectedpacingmodevalue =                             ext.getcmp(paramname + 'pickerfield').getvalue()[paramname];                         sendsetpendingrequest(paramname, selectedpacingmodevalue);                     }                 }             }         });     } }

lets take these values in picker field. doing on select of value , click of "donebutton", showing value in textfield. want if select "option 2" , click "donebutton" option 2 shouldn't displayed in textfield other values selecting , showing in textfield operation should work.

you can selected record , check flag upon click of done button, move textbox (or not).

ext.create('ext.form.panel', {     fullscreen: true,     items: [         {             xtype: 'fieldset',             title: 'select',             items: [                 {                     xtype: 'selectfield',                     itemid: 'myselectfield',                     label: 'choose one',                     options: [                         {                             text: 'apple',                             value: 50                         }, {                             text: 'orange',                             value: 100,                             disabled: true                         }, {                             text: 'banana',                             value: 200                         }, {                             text: 'papaya',                             value: 300                         }                     ]                 },                 {                     xtype: 'button',                     text: 'done',                     handler: function(button){                         var panel = button.up(),                             sf = panel.down('#myselectfield'),                             tf = panel.down('#answerfield');                          /* can access raw value unless use                          * actual store , actual model                           * disabled field. in case can                          * sf.getrecord().get('disabled')                          */                          if(sf.getrecord().raw.disabled === true){                             tf.setvalue(''); //noting see :)                         } else {                             tf.setvalue(sf.getrecord().get('text')); //display value                         }                     }                 },                 {                     xtype: 'textfield',                     itemid: 'answerfield',                     title: 'answer'                 }             ]         }     ] });
