通过Angular中的多个字段
如何以角度同时使用多个字段进行排序?例如,先按组再按子组 $scope.divisions = [{'group':1,'sub':1}, {'group':2,'sub':10}, {'group':1,'sub':2},{'group':1,'sub':20},{'group':2,'sub':1}, {'group':2,'sub':11}]; 我想显示为 组:子组 1-1 1-2 1-20 2-1 2-10 2-11 <select ng-model="divs" ng-options="(d.group+' - '+d.sub) for d in divisions | orderBy:'group' | orderBy:'sub'" />
