angular.js - An issue with loops in angular directives

Question

There is a variable a=30; how to loop out the thirty numbers from 1 to 30 in the angular HTML command? It is not the output of an array, it is a loop of numbers with a step size of 1

I can’t think of a better way. To operate an array with ng-repeat, you must create an array

html


  

     

          {{$index+1}}

js

angular.module('app', []).controller('MainCtrl', function($scope){
    $scope.a = 30;
    $scope.arr = new Array($scope.a);
});
