Question

这是Codepen：

在Codepen上，您会找到两个选择框。一个预先选择了第二个最后一个选项，另一个选择了最后一个选项。

问题是我无法预先选择下拉框中的最后一个选项。

angular.module('ionicApp', ['ionic'])

.controller('MyCtrl', function($scope) {
 
  var values = [{"id":"84279ed396g5l6kj","name":"One"},{"id":"62d9lg85llek38j7","name":"Two"},{"id":"46327g3839elk5j9","name":"Three"},{"id":"8kj65g6536el47d2","name":"Four"},{"id":"46l38el98jg57d2k","name":"Five"},{"id":"7kd35g4k3lej698l","name":"Six"}];
  
  $scope.typeWorking = {
    "value": '46l38el98jg57d2k',
    "values": values
  };
  
   $scope.typeNotWorking = {
    "value": '7kd35g4k3lej698l',
    "values": values
  };
  
});

Answer 1

您的代码中存在错误，name.id == name.value应为name.id == typeNotWorking.value

<option value="{{ name.id }}" ng-selected="name.id == typeNotWorking.value" ng-repeat="name in typeNotWorking.values">{{ name.name }}</option>

无法在Ionic Select中预先选择最后一个选项
