Question

我创建了一个通用对话框指令，我用它来显示创建，编辑，删除等表单。

它工作正常，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。这听起来很容易但是我创建这个指令的方式看起来非常困难。

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();
            };
        }
    }
  });

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',
            dlgPosClick: '&dlgPosClick',
            dlgIsValid: '=dlgIsValid'
        },
        link: function (scope, element, attrs) {
            scope.dlgNegClick = function (e) {
                $(".modal").click();
                e.stopPropagation();
            };
        }
       }
     });

Html代码：

<!DOCTYPE html>
<html ng-app="productApp">

<head>
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.12/angular.min.js"></script>
  <script src="app.js"></script>

  <div ng-controller="createProduct">
    <form role="form" name="productForm" dlg dlg-title="Create Product" dlg-pos-text="Create" dlg-pos-click="createProduct()" dlg-is-valid="productForm.$valid">
      <div class="listrow">
        <span class="listrow_label">Name</span>
        <span>: </span>
        <span class="listrow_value">
            <input type="text" name="Name" data-ng-model="vm.Name" class="listrow_value" data-ng-required="true" style="width: 339px"></span>
        <span data-ng-show="productForm.Name.$invalid" class="val-hl">*</span>
      </div>
      <button type="button" ng-click="createProduct()" ng-disabled="isUploading">{{isUploading?"Uploading":"upload"}}
