在 Angular JS 中重新启用禁用 ng 的按钮

re enabling ng-disabled button in Angular JS

本文关键字：ng 按钮 启用 JS Angular 新启用      更新时间：2023-09-26

我是AngularJS的新手。我创建了一个带有字段的表单，默认情况下使用 ng-disabled 禁用该字段。当我单击编辑<button>时，我希望这些字段重新启用。

.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>

控制器

  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
      });
  }

在控制器中创建作用域变量，

$scope.disabled= true;

并将所有ng-disabled替换为该变量，例如，

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

当您单击编辑按钮时，$scope.disabled设置为false喜欢，

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

您可以使用一个范围变量来保存true或false值，并为该变量设置一个资源库。

  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;
};

}

在你的HTML中，你可以绑定那个getter函数。

 <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>
你需要

在控制器的顶部创建一个变量，比如

$scope.mydisabled=true;

然后使用变量设置您的 ng 禁用

ng-disabled="mydisabled"

并在单击编辑按钮时将其值设置为 false

$scope.mydisabled=false;

另一种（无论多么相似）的方法是将表单内容包装在字段集中，并在字段集中禁用 ng，而不是在所有输入字段中禁用。使 html 更清晰。

<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>

现在在控制器中，根据您的逻辑将 isFormSetForSave 设置为 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;
      });
  }
