javascript - 在 Angular JS 中重新启用 ng-disabled 按钮

Question

我是 AngularJS 的新手。我创建了一个表单，其中包含使用 ng-disabled 禁用的字段默认。当我点击编辑 <button>我希望重新启用这些字段。

HTML

  <form class="form-horizontal" role="form" ng-submit="edit_setting()" ng-controller="ExchangeController">
    <div class="form-group">
      <label>Name</label>
      <div class="col-sm-6">
        <input type="text" class="form-control" ng-model="exchange_dt.name" ng-disabled="true">
      </div>
    </div>
    <div class="form-group">
      <label>Host Name</label>
      <div class="col-sm-6">
        <input type="text" class="form-control" ng-model="exchange_dt.host_name" required ng-disabled="true">
      </div>
    </div>
    <div class="form-group">
      <label>Address</label>
      <div class="col-sm-6">
        <input type="text" class="form-control" ng-model="exchange_dt.address" ng-disabled="true">
      </div>
    </div>
  </form>

Controller

  function ExchangeController($scope, $http, $cookieStore, $location) {
    var edit_exchange_setting = "https://pvbp.com/api/settings.html?contactid=292351&exchange_id=7124&clearinghouseid=1&token=e5349652507c0esae86d50fdbdc53222cf97&page=view";
      $http.get(edit_exchange_setting).success(function(response){
        $scope.exchange_dt.exchange_name = response.name;
        $scope.exchange_dt.exchange_host_name = response.host_name;
        $scope.exchange_dt.exchange_last_processed_date = response.address;   
      });

      $scope.edit_exchange_setting_click = (function(){
      // how can i make the fields re enable here

      });
  }

在 Controller 中创建作用域变量，

$scope.disabled= true;

并用该变量替换所有 ng-disabled，例如，

...ng-model="exchange_dt.name" ng-disabled="disabled"....

当您单击编辑按钮时，将 $scope.disabled 设置为 false，例如，

$scope.edit_exchange_setting_click = (function(){      
    $scope.disabled = false;
});
