javascript如何在点击这个“查看”的时候让“保存”这个button失效？

{
xtype:'gridcolumn',
header:'操作',
width:60,
sortable:true,
renderer:function (value, metadata, record, rowIndex, colIndex, store) {
return "<div width='30' align='center'><a href=javascript:edit_window(" + rowIndex + ")><img src='" + _root + "/res/img/biaoji/edit.png' title='编辑'/><a href=javascript:view_window(" + rowIndex + ")><img src='" + _root + "/res/img/biaoji/lookup.png' title='查看'/></a></div>";
}
},

跳转到
function view_window(){
var rec = sw_editorgridpanelUiIns.getSelectionModel().getSelected();
windowUiIns = new windowUi();
windowUiIns.show();
Ext.getCmp('dbid').setValue(rec.get('dbid'));
Ext.getCmp('code').setValue(rec.get('code'));
Ext.getCmp('name').setValue(rec.get('name'));
Ext.getCmp('count_student').setValue(rec.get('count_student'));
Ext.getCmp('teacher_name').setValue(rec.get('teacher_name'));
Ext.getCmp('staff_name').setValue(rec.get('staff_name'));
Ext.getCmp('create_date').setValue(rec.get('create_date'));
setReadOnlyWithCss(['code', 'name', 'count_student', 'teacher_name'],true)
}

button
this.tbar={
xtype:'toolbar',
items:[

{
xtype:'button',
text:'保存',
iconCls:'save',
handler:function (){
win_save();
}
},
]
};

点击查看的时候，单击事件里获得button的对象，button对象.disabed=true,而且要加个条件，使没点查看的时候button对象.disabed=false

追问

如何在view_window()里面获取button对象呀？
需要怎么设置id？
语句怎么写，谢谢啦

追答

document.getElementById("buttonid")就是button的对象了啊，就是把disabed在true和false间切换就是了

追问

我写了还是不行啊
全部的语句是怎样的呀。。。谢谢
