getSelectionModel().getSelections()什么意思

 var cumgrid = new Ext.grid.GridPanel({
     width:600,
     autoHeight:true,
     //列重新计算后自动填满[Ext.grid.GridView]
     viewConfig:{
         forceFit:true,
         columnsText:"显示的列",
         sortAscText:"升序",
         sortDescText:"降序"
     },
        store:store,
        cm:cm,
        sm:sm,
        renderTo:"cumgrid"
    }); 

    store.load();
    cumgrid.on("click",function(){
        var selections = cumgrid.getSelectionModel().getSelections();
        for(var i=0;i<selections.length;i++){
         var record = selections[i];
         Ext.Msg.alert("提示","您所选中的行的编号为"+record.get("memid")+",名称为"+record.get("memName"));
        }
    });

解决方案

ext中
cumgrid.getSelectionModel().getSelections()是选中的行数据

解决方案二：

Returns an array of the currently selected records.获取gridpanel当前选中的数据行
