我发现了一种即时更新的方法。基本上，我保留了所有数据的隐藏集，并且在接收到新数据或更改过滤器后-我将此过滤器应用于完整数据集，并将网格交给过滤后的版本。
这使我可以在过滤器中使用 比较器 （即年龄> = 50），这是此问题的目的。
// Full unfiltered data set$scope.entries = []; // Updated and pushed to$scope.gridOptions = { // The grids already filtered data set data: 'filteredEntries', enableColumnResize: false, multiSelect: false, enableSorting: false, selectedItems: $scope.selectedEntries,} $scope.$on("updateEntries", function(data) { // My table is filled by socket pushes, this is where it is updated. $scope.updateFilters(); } $scope.$on("newFilter", function(newFilter) { // This is where I update my filter $scope.updateFilters(); } $scope.updateFilters = function() { // Filters the full set and hands the result to the grid. $scope.filteredEntries = $filter('filter')($scope.entries, $scope.myFilter); $scope.$digest(); } // A modifiable limit, modify through newFilter so data is refiltered $scope.lowerLimit = 50; // My Filter $scope.myFilter = function(entry) { if (entry < $scope.lowerLimit) { return false; } return true; }
