在使用limitTo再次过滤之前，请查看已过滤的ngRepeat数组的大小。

Question

I'm currently paginating my ngRepeat through a combination of a custom startAtIndex filter and a limitTo filter. I want to display the total number of results in the data set regardless of the page. However, when you use limitTo , this obviously chops the array off at that point, and you can't get the length property you want.

My ngRepeat :

ng-repeat-start="colleague in pagination.filteredData = (colleagueDataArray | filter:{name: queries.name} | filter:{client: queries.client} | filter:queries.generalQuery | orderBy:sortByField:reverseSort | startFrom: pagination.startAtIndex | limitTo:pagination.pageSize)">

I assign the results of the filter to the pagination.filteredData object, I can then display it's length anywhere in my controller with {{pagination.filteredData.length}} .

How can I go about this to get the length of the filtered array before it's filtered by startAtIndex and limitBy ? Can I somehow partially filter the colleagueDataArray array, and then filter the resulting filteredArray again with the ngRepeat ?

If this makes no sense to you, please let me know so I can edit the question.

Write a custom filter, whatever you are trying there.

ng-repeat="data in bigData | filter:myfilter"

$scope.myfilter= function(data)
{
    // Check length or i dont know
    // $scope.bigData.length 

    if($scope.bigData.length > 2)
    {
        return true; // this will be listed in the results
    }

    return false; // otherwise it won't be within the results
};
