在Angular JS中重新啟用ng-disabled按鈕

Question

我是AngularJS的新手。 我創建了一個包含字段的表單，默認情況下使用ng-disabled 。 當我點擊編輯<button>我希望這些字段重新啟用。

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>

  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

      });
  }

Answer 1

在控制器中創建范圍變量，

$scope.disabled= true;

並用該變量替換所有ng-disabled ，如，

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

當你點擊編輯按鈕將$scope.disabled設置為false ，

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

Answer 2

你可以讓一個范圍變量保持true或false值。並為該變量設置一個setter。

  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

  });

  $scope.dtName=true;
   $scope.isdtNameDisabled=function()
    {
      return $scope.dtName;
    };
  $scope.updatedtName=function(flag)
  {
  $scope.dtName=flag;
};

}

在HTML中，您可以綁定該getter函數。

 <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="isdtNameDisabled()>
  </div>
</div>

Answer 3

你需要在控制器頂部創建一個變量說

$scope.mydisabled=true; 

然后使用變量設置ng-disable

NG-禁用= “mydisabled”

並在單擊編輯按鈕時將其值設置為false

$scope.mydisabled=false;

另一種（但是類似的）方法是將表單內容包裝在字段集中，並且僅在字段集中使用ng-disabled而不是在所有輸入字段中。 使html更清潔。

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

現在在控制器中根據您的邏輯將isFormSetForSaving設置為true / false。

function ExchangeController($scope, $http, $cookieStore, $location) {
    $scope.isFormSetForSaving = true;
    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
          $scope.isFormSetForSaving = false;
      });
  }
