_.filter

data:[         {value:10, name:'产品'},          {value:5, name:'服务'},          {value:15, name:'业务'},          {value:25, name:'其他'},          {value:20, name:'平台'}       ]

将产品后边加上一个selected：true，

   _.filter($scope.data, function(o) {            if(o.name=='产品'){              o.selected=true;              return false;            }          });
