javascript - AngularJS: Prevent displaying the last separator when repeating multiple arrays -

-

question: elegant way ensure last separator on each line never shown?

11|18|3|8|12|1|22|31|61| 11:18:3:8:12:1:22:31: 11,18,3,8,12,61, 1 22 31

note data originates 3 different arrays, e.g., data line 1 defined as:

$scope.numbers = [11,18,3,8,12]; $scope.specialnumbers = [1,22,31]; $scope.additionalnumbers = [61];

i see more elegant/angular way, finding last <li> , remove separator using $element.find, or similar.

i created little jsfiddle example demonstrate problem.

thanks

here complete solution, using proposed $last check (only once) in combination array.concat, supported in angular expressions , supports bindings. however, correctly repeat literals, need track $index.

"<li ng-repeat='num in numbers.concat(specialnumbers,additionalnumbers) " +                "track $index'>" +     "<span>{{ num }}</span><span ng-if='!$last'>{{ separator }}</span>" +  "</li>"
