我想把文本从“是”改为“是！！！”从“不”到“不！！！”我尝试了很多东西，但似乎都没用。找不到有关Sencha的任何文档，如果有人能帮上忙，谢谢

Ext.application({
    name: 'Fiddle',

    launch: function() {
Ext.Msg.confirm('Confirmation', "Do you want to cancel the order?", function(btnText){
                //btnText = {
                //    yes: "YES!!",
               //   no: "NO!!"
               //}, 
               //btnText.setText("YESSS!!"),    
                if(btnText === "yes"){
                    Ext.Msg.alert("Alert", "You have cancelled the order.");
               }
               else if(btnText === "no"){
                    Ext.Msg.alert("Alert", "You have confirmed 'No'.");

               }
            }, this);
    }
});

Ext.application({
    name: 'Fiddle',
    launch: function() {                
        Ext.Msg.show({
        title: 'Title',
        message: 'Message',
        buttons: {
           yes: 'Cancel preAuth',
           no: 'Cancel the whole order',
           cancel: 'Do nothing!'
        },  
              fn: function(buttonValue, inputText, showConfig) {
                if(buttonValue === "yes"){
                    Ext.Msg.alert("Alert", "You have cancelled the order.");
               }
               else if(buttonValue === "no"){
                    Ext.Msg.alert("Alert", "You have confirmed 'No'.");
               }
            }, this);
    }
});
