ng-repeat索引,按字母顺序排列

Question

我希望以$index字母格式输出而不是编号.

<div ng-repeat="name in names">{{$index}}</div>

这可能吗？

Answer 1

这是我找到的解决方案:

使用Javascript:

// the alphabet    
$scope.alphabet['A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z'];

// get the index and return the letter of the alphabet
$scope.getLetter = function(index) {

  return $scope.alphabet[index];

};

HTML:

<div ng-repeat="name in names">{{getLetter($index)}}</div>

编辑(感谢@TheShalit和@patrick):

使用Javascript:

// get the index and return the letter of the alphabet
$scope.getLetter = function(index) {

  return String.fromCharCode(65+index);

};

HTML:

<div ng-repeat="name in names">{{getLetter($index)}}</div>
