单击按钮后如何根据日期过滤交易记录？

Question

scope.routeToTxn = function(){
    route.reload();
    var items= scope.initPage().items;
    routeParams.fromDate=filter('date')(scope.formData.fromDate, 'dd MMM yyyy');
    routeParams.toDate=filter('date')(scope.formData.toDate, 'dd MMM yyyy');
  return function( items ) {
        var filtered=[];
        var txnstartDate = routeParams.fromDate;
        var txnendDate = routeParams.toDate;
        angular.forEach(items, function(item) {
            if(items.txnDate > txnstartDate && items.txnDate < txnendDate) {
                filtered.push(item);
            }
        });
        return filtered;
    };
  };

<a ng-click="routeToTxn()" class="btn btn-primary">{{'label.button.cashier.showtxn' | translate}} </a>




<tr dir-paginate="txn in cashierTransactions  | orderBy:'txn.txnDate' |filter:filterText | itemsPerPage: txnPerPage" total-items="totaltxn">

点击（routeToTxn）按钮后，交易数据应基于2个日期进行过滤。

 scope.routeToTxn = function(){
        route.reload();
        routeParams.fromDate=filter('date')(scope.formData.fromDate, 'dd MMM yyyy');
        routeParams.toDate=filter('date')(scope.formData.toDate, 'dd MMM yyyy');

        return function( items ) {
            var filtered=[];

            var txnstartDate = routeParams.fromDate;
            var txnendDate = routeParams.toDate;

            angular.forEach(items, function(item) {
                if(items.txnDate > txnstartDate && items.txnDate < txnendDate) {
                    filtered.push(item);
                }
            });
            return filtered;
        };
   };

<a ng-click="routeToTxn()" class="btn btn-primary">{{'label.button.cashier.showtxn' | translate}} </a>


<tr dir-paginate="txn in cashierTransactions  | orderBy:'txn.txnDate' |filter:filterText | itemsPerPage: txnPerPage" total-items="totaltxn">

交易数据是从后端导入的。

scope.initPage = function () {
        var items = resourceFactory.tellerCashierSummaryAndTxnsResource.getCashierSummaryAndTransactions({
            tellerId: routeParams.tellerId,
            cashierId: routeParams.cashierId,
            fromDate: routeParams.fromDate,
            toDate: routeParams.toDate,
            currencyCode: routeParams.currencyCode,
            offset:0,
            limit: scope.txnPerPage
        }, function (data) {
            scope.cashierSummaryAndTxns = data;
            scope.totaltxn = data.cashierTransactions.totalFilteredRecords;
            scope.cashierTransactions = data.cashierTransactions.pageItems;
        });
    }
