Question

我无法获得初始化值的输入

查看：

<form ng-submit="changeDistance(form)" id="form">
  <input min="1" max="50" ng-model="form.distance" type="range"> 
  <button type="submit" >
  Done
  </button>
</form>

控制器：

$scope.form = {};
$scope.form.distance = $localStorage.distance;

$scope.changeDistance = function(form){
 $localStorage.distance = form.distance;
}

这样可行，但问题是无法提交值：

View:

    <form ng-submit="changeDistance(form)" id="form">
      <input min="1" max="50" ng-model="distance" type="range"> 
      <button type="submit" >
      Done
      </button>
    </form>

Controller:


    $scope.distance = $localStorage.distance;

    $scope.changeDistance = function(form){
     console.log(form.distance)//cannot read
    }

Answer 1

这是Angular 1.2的确认错误。有关详细信息，请参阅Github bug report。

Answer 2

尝试使用角度为1.3.14及以上的上述代码（使用ng-model="form.distance"的地方）。
