Ext.grid.ColumnModel如何获取其他列的值

[code="java"]{header: "密码", sortable:true, dataIndex:"card_password",renderer:function(value){return ""+value+""}},
{header: "创建者", sortable:true,width: 60, dataIndex:"card_admin",renderer:function(value){return ""+value+""}},
[/code]
我的密码要根据创建者来显示,有些创建者密码要隐藏,这个功能要怎么做啊?

[code="js"]
renderer:function(value, cellMeta, record, rowIndex, columnIndex, store)
{
// 得到创建者信息
var creator = record.data['card_admin'];
// 是否显示密码(boolean)
var isShowPassword = 自己的逻辑判断(creator);

  return "<span style='color:#000000;'>"+isShowPassword ? value : ''+"</span>"}

}
// value: 当前的值
// cellMeta: 单元格式ID
// record: 当前行的所有数据
// rowIndex: 当前行的行号(分页后的)
// columnIndex: 列号
// store: 数据集
[/code]

renderer有6个参数:
[quote]* value : Object
The data value for the cell.

  • metadata : Object
    An object in which you may set the following attributes:
    o css : String
    A CSS class name to add to the cell's TD element.
    o attr : String
    An HTML attribute definition string to apply to the data container element within the table cell (e.g. 'style="color:red;"').

  • record : Ext.data.record
    The Ext.data.Record from which the data was extracted.

  • rowIndex : Number
    Row index

  • colIndex : Number
    Column index

  • store : Ext.data.Store
    The Ext.data.Store object from which the Record was extracted.[/quote]
    第3个参数就是record,用record.get(fieldName)来取其它列的值。例:record.get("card_admin")
