extjs—renderer

Extjs的renderer关健字可以通过一个方法改变当前绑定的数据显示内容

//新闻状态方法
function getStatusText(value)
        {
            var result = '禁用';
            switch(value){
                case 0:
                    result = '禁用';
                    break;
                case 1:
                    result = '启用';
                    break;
            }
            return result;
        }

//返回新闻内容链接地址(value：当前字段值,p:不知道是啥,record表示当前记录,不需要定义)
function getNewsContent(value,p,record)
{
    return String.format(
'<a href=# onclick=alert({0})>'+ GetLeft(value,10,"..") +' (查看)</a>',record.data.ID)
}
var grid = new Ext.grid.GridPanel({
id: 'gridPaging',
renderTo: 'divPaging',
.......
columns:[
selModel,
new Ext.grid.RowNumberer(),     //  自动行号,
                    {
                        header: "新闻ID",
                        dataIndex: 'NewsID',
                        width: 50,
                        hidden: false,
                        sortable: true
                    },{
                        header: '新闻标题',
                        dataIndex: 'Name',
                        width: 100,
                        hidden: false,
                        sortable: true
                    },{
                        header: '新闻状态',
                        dataIndex: 'Status',
                        renderer: getStatusText,   //调用一个方法getStatusText, 通过当前vlaue来改变值
                        width: 50,
                        sortable: true
                    },{
                        header: '新闻内容,
                        dataIndex: 'Status',
                        renderer: getNewsContent,   //调用一个方法getNewsContent,返回一个超级链接                      width: 50,
                        sortable: true
                    }
