Question

我在表单中有一个输入和一个按钮。

我想输入输入并按Enter键，提交输入内容并触发打开模式，显示结果。我不知道如何在没有获得自定义/ hacky的情况下触发ng-submit模式。这样做是否有理解的方法？

目前：

<form>
    <div ng-show="thirdPhase" class="input-group animated fadeIn">
        <input type="text" class="form-control finderBar" placeholder="City, State..." autofocus>
        <span class="input-group-btn">
            <button data-toggle="modal" data-target="#searchModal" class="btn btn-default" type="button">Go!</button>
        </span>
    </div>
</form>

和模态：

<div class="modal fade" id="searchModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Search Results</h4>
      </div>
      <div class="modal-body">
        TEST SEARCH MODAL
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>
  </div>
</div>

我尝试将典型的模态触发器属性放在表单元素中，但只要单击表单内的输入，就会立即触发模态。

在下面的示例中，我创建了自己的模态指令。

<强> HTML：

<div ng-controller="MainCtrl" class="container">
    <h1>Modal example</h1>
    <form ng-submit="toggleModal()">
        <div class="input-group animated fadeIn">
            <input type="text" class="form-control finderBar" placeholder="City, State..." autofocus>
            <span class="input-group-btn">
                <button class="btn btn-default" type="submit">Go!</button>
            </span>
        </div>
    </form>

    <modal title="Search Results" visible="showModal">
        TEST SEARCH MODAL
    </modal>
</div>

<强> JS：

var mymodal = angular.module('mymodal', []);

mymodal.controller('MainCtrl', function ($scope) {
    $scope.showModal = false;
    $scope.toggleModal = function(){
        $scope.showModal = !$scope.showModal;
    };
});

mymodal.directive('modal', function () {
    return {
      template: '<div class="modal fade">' + 
          '<div class="modal-dialog">' + 
            '<div class="modal-content">' + 
              '<div class="modal-header">' + 
                '<button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>' + 
                '<h4 class="modal-title">{{ title }}</h4>' + 
              '</div>' + 
              '<div class="modal-body" ng-transclude></div>' + 
            '</div>' + 
          '</div>' + 
        '</div>',
      restrict: 'E',
      transclude: true,
      replace:true,
      scope:true,
      link: function postLink(scope, element, attrs) {
        scope.title = attrs.title;

        scope.$watch(attrs.visible, function(value){
          if(value == true)
            $(element).modal('show');
          else
            $(element).modal('hide');
        });

        $(element).on('shown.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = true;
          });
        });

        $(element).on('hidden.bs.modal', function(){
          scope.$apply(function(){
            scope.$parent[attrs.visible] = false;
          });
        });
      }
    };
});

您可以使用ui-bootstrap以及@Pankaj Parkar建议。

所以假设你不想要一个特殊的按钮来弹出模态，并且只是ngSubmit引导方式（而且没有得到hacky），你需要修改你的html到这样的东西，

    <div ng-controller="whateverYouWant" data-target="#searchModal" data-toggle="modal">
        <form ng-submit="submit()">
            <div ng-show="thirdPhase" class="input-group animated fadeIn">
                <input type="text" class="form-control 
finderBar" placeholder="City, State..." autofocus>
                <span class="input-group-btn">
                </span>
            </div>
        </form>
    </div>

注意我从HTML中删除了<button>，并将data-target和data-modal放在了{-1}}中，其中包含ng-controller。

最后将脚本修改为以下内容：

<div>

这样，当ng-submit完成其任务时，它会自动初始化模态，你可以使用$scope.submit = function (){ . . . $('#searchModal').modal('show'); }来绑定数据。

结帐Modals。

正如评论中所提到的，最好使用angular-ui-bootstrap。

然后你可以创建一个工厂来创建模态，你可以从第一个modalInstanceController的方法中打开结果模态。

演示中的工厂非常基础，可以改进，例如使用参数传递控制器名称以避免硬编码控制器名称。

请查看下面的演示或此jsfiddle。

angular.module('ui.bootstrap.demo', ['ui.bootstrap'])
  .factory('modalFactory', function($uibModal) {
    return {
      open: function(size, template, params) {
        return $uibModal.open({
          animation: true,
          templateUrl: template || 'myModalContent.html',
          controller: 'ModalResultInstanceCtrl',
          size: size,
          resolve: {
            params: function() {
              return params;
            }
          }
        });
      }
    };
  })
  .controller('ModalDemoCtrl', function($rootScope, $scope, $log, $uibModal) {

    //$scope.items = ['item1', 'item2', 'item3'];

    //$scope.animationsEnabled = true;

    $scope.open = function(size, template) {
      var modalInstance = $uibModal.open({
          animation: $scope.animationsEnabled,
          templateUrl: template || 'myModalContent.html',
          controller: 'ModalInstanceCtrl',
          size: size
        });

      /*modalInstance.result.then(function(selectedItem) {
        $scope.selected = selectedItem;
      }, function() {
        $log.info('Modal dismissed at: ' + new Date());
      });*/
    };

    $scope.toggleAnimation = function() {
      $scope.animationsEnabled = !$scope.animationsEnabled;
    };

  });

// Please note that $modalInstance represents a modal window (instance) dependency.
// It is not the same as the $uibModal service used above.

angular.module('ui.bootstrap.demo').controller('ModalInstanceCtrl', function($scope, $uibModalInstance, modalFactory) {

  //$scope.searchTerm = term;

  $scope.ok = function() {
    modalFactory.open('lg', 'result.html', {searchTerm: $scope.searchTerm});
    //$uibModalInstance.close($scope.searchTerm);
  };

  $scope.cancel = function() {
    $uibModalInstance.dismiss('cancel');
  };
});

angular.module('ui.bootstrap.demo').controller('ModalResultInstanceCtrl', function($scope, $uibModalInstance, params) {

  $scope.searchTerm = params.searchTerm;

  $scope.ok = function() {
    $uibModalInstance.close($scope.searchTerm);
  };

  $scope.cancel = function() {
    $uibModalInstance.dismiss('cancel');
  };
})
