ExtJs4怎么修改和操作Panel的html属性值

操作方法见下面的代码：

khzbGrid.on('select', function( rowModel, record, index, eOpts ) {
        var zbms = record.get('zbms');//指标表述
        var zbfdsm = record.get('fjsm');//指标分档说明
        Ext.getCmp('eastZbmsPanel').body.update('<div tyle="font-size:smaller">' + zbms + '</div>');
        Ext.getCmp('southZbfdsmPanel').body.update('<div tyle="font-size:smaller">' + zbfdsm + '</div>');
});
