【中文标题】单击angularjs后禁用按钮【英文标题】:Disable button after click in angularjs 【发布时间】:2017-08-30 15:06:14 【问题描述】:我创建了一个通用对话框指令,用于显示创建、编辑、删除等表单。
它运行良好,但现在我需要禁用“创建”按钮,除非我收到来自 Web 服务的响应。这听起来很简单,但我创建这个指令的方式看起来很困难。

angular.module('productApp', [])
.controller("createProduct", function($scope, $timeout)
$scope.status = "loading";
$scope.createProduct = function ()
var newProduct = 'Title': $scope.Name ;
//datacontext.createProduct(newProduct)
// .then(function (data)
// location.path("/categories/" + data.data.CategoryID + "/products/" + data.data.ID, false);
// window.location.reload();
// )
// .finally(function ()
// $scope.$close();
// );
setTimeout(function() alert("product saved"); , 10000);
)
.directive("dlg", function()
return
transclude: true,
templateUrl: 'dialog.html',
scope:
dlgTitle: '@dlgTitle',
dlgPosText: '@dlgPosText',
dlgPosClick: '&dlgPosClick',
dlgIsValid: '=dlgIsValid'
,
link: function (scope, element, attrs)
scope.dlgNegClick = function (e)
$(".modal").click();
e.stopPropagation();
;
);

【参考方案1】:我更改了您的代码,请检查一次
angular.module('productApp', [])
.controller("createProduct", function($scope, $timeout)
$scope.status = "loading";
$scope.isUploading = false;
$scope.createProduct = function ()
$scope.isUploading = true;
var newProduct = 'Title': $scope.Name ;
//datacontext.createProduct(newProduct)
// .then(function (data)
// location.path("/categories/" + data.data.CategoryID + "/products/" + data.data.ID, false);
// window.location.reload();
// )
// .finally(function ()
// $scope.$close();
// );
setTimeout(function() alert("product saved"); $scope.isUploading = false;, 10000);
)
.directive("dlg", function()
return
transclude: true,
templateUrl: 'dialog.html',
scope:
dlgTitle: '@dlgTitle',
dlgPosText: '@dlgPosText',

dlgIsValid: '=dlgIsValid'
,
link: function (scope, element, attrs)
scope.dlgNegClick = function (e)

e.stopPropagation();

【讨论】:
感谢 ankit,但您的示例对我不起作用 anikit,谢谢,它现在来回更改 is-upload 但实际上并没有禁用创建按钮 感谢 ankit 它正在工作,但不是我希望它工作的方式,如果您在我的代码中看到我使用对话框作为模板,然后将控制器的选项注入其中,但是您的最新示例有一个创建表单中的按钮不是我想要的,我想在指令中保留创建按钮,以便我可以在不同的表单/控制器中使用它以上是关于单击angularjs后禁用按钮的主要内容,如果未能解决你的问题,请参考以下文章
