Answer 1

首先把hiddenLanel:true属性去掉.然后select 函数修改如下:
select:function(combo, record, index){
//alert(record.get('type')+" index : "+index +" combo : "+combo);
var t=record.get('type');
alert(t);
if(t==0){
Ext.getCmp('passwordId').setDisabled(false);
Ext.getCmp('passwordId').setVisible(true);
}else{
Ext.getCmp('passwordId').setDisabled(true);
Ext.getCmp('passwordId').setVisible(false);
}
你可以试试看 行不行.

Answer 2

this.password 中 hiddenLabel:true 这句话去掉
