Extjs GridPanel 监听事件 行选中背景

 Extjs设置GridPanel选中行背景色和选中单元格背景色 

var view = grid.getView();

view.getRow(index).style.backgroundColor = "red";  //选中行背景色

view.getCell(rowIndex,colIndex).style.backgroundColor = "red";  //选中单元格背景色

我在开发时是在CheckboxSelectionModel中的beforerowselect中进行设置的：

var smQd = new Ext.grid.CheckboxSelectionModel({
　　'beforerowselect':function(sm,rowIndex,keepExisting,record){
                           var l = storeXtcpyy.getCount();
                           for(var i=0;i<l;i++){
                               if(i%2 == 0){
                                   var view = gridXtcpyy.getView();
                                view.getRow(i).style.backgroundColor =                                         "white";
                               }else{
                                   var view = gridXtcpyy.getView();
                                   view.getRow(i).style.backgroundColor =                                         "#FAFAFA";
                               }
                           }
                      }
                 }
　　    });

gridXtcpyy.addListener('cellclick', function (grid, rowIndex, columnIndex, event) {
    var view = gridXtcpyy.getView();
    view.getRow(rowIndex).style.backgroundColor = "#DFE8F6"; 
　　}, gridXtcpyy);
