Answer 2

谢谢版主回复 不过我改成下面的 还是没有效果，异议类型为A时，还是可以编辑
           fieldLabel: '异议类型',
                name: 'ObjectionType',
                readOnly: true,
                allowBlank: false,
                listeners: { keypress: function (o, e, eOpts) { Ext.getCmp('txtMoney').setReadOnly(o.getValue() == '买方违约') } }
            }, {
                fieldLabel: '异议种类',
                name: 'ObjectionMode',
                readOnly: true,
                allowBlank: false
            }, {
                fieldLabel: '异议内容',
                name: 'ObjectionContent',
                readOnly: true,
                allowBlank: false
            }, {
                xtype: 'numberfield',
                fieldLabel: '退还资金',
                name: 'RefundMoney',
                allowBlank: false, 
                id: 'txtMoney'
            }]

Answer 3

为省事，A 就是上面代码中的 买方违约弱弱的问下版主， 为什么这里用的是 keypress？ 

Answer 4

原本是想用blur事件的，但是blur事件需要ext4.1+版本，不知道你的ext版本多少的

Answer 5

如果是版本原因， 那 不用listeners， 还有能有其他适合的方法吗

Answer 6

2.0...api都不知道去哪找来看了。。自己看2.0的apisetReadOnly好像都要2.3+才支持这个方法

Answer 7

 
原来这样， 谢谢版主了。也算学习了setReadOnly
