Question

我在单页上显示两种类型的数据，一种是插入表单，第二种是在Angular dataTables的帮助下显示数据的位置，现在我想要做的就是当我点击编辑时我在“插入”表单中显示数据字段还将“保存”按钮从“保存”更改为“更新...”我已经尝试了但是我收到此错误，尽管它在控制台中显示数据。

controller.js:1356 24
controller.js:1363 Colony 02 2
angular-1.4.8.js:12520 TypeError: Cannot set property 'colony_name' of undefined

注意：插入，删除，显示数据工作正常。

这是我的HTML PAGE

Answer 1

在您的模板中，您输入了ng-model="field.colony_name"，但在您的控制器中，您从未定义过$scope.field。您确实在var values = $scope.field函数中指定了值$scope.InsertData，但这只会将values设置为undefined。

尝试初始化变量，方法是将$scope.field = {}添加到控制器的开头，作为初学者。这将解决您遇到的错误。

Answer 2

以下是可能对您有用的代码。 Html：

<div ng-app="myApp" ng-controller="MainCtrl">
   <fieldset  data-ng-repeat="choice in choices">          
      <input type="text" ng-model="choice.name" name="" placeholder="Enter mobile number"> <button class="remove" ng-show="$last" ng-click="removeChoice()">-</button>
   </fieldset>
   <button class="addfields" ng-click="addNewChoice()">Add fields</button>           
   <div id="choicesDisplay">
      {{ choices }}
   </div>
</div>

<强> JS：

var app = angular.module('myApp', []);    
app.controller('MainCtrl', function($scope) { 
    $scope.choices = [{id: 'choice1'}, {id: 'choice2'}];      
    $scope.addNewChoice = function() {
        var newItemNo = $scope.choices.length+1;
        $scope.choices.push({'id':'choice'+newItemNo});
    };

    $scope.removeChoice = function() {
        var lastItem = $scope.choices.length-1;
        $scope.choices.splice(lastItem);
    };

});

还有CSS：

fieldset{
    background: #FCFCFC;
    padding: 16px;
    border: 1px solid #D5D5D5;
}
.addfields{
    margin: 10px 0;
}

#choicesDisplay {
    padding: 10px;
    background: rgb(227, 250, 227);
    border: 1px solid rgb(171, 239, 171);
    color: rgb(9, 56, 9);
}
.remove{
    background: #C76868;
    color: #FFF;
    font-weight: bold;
    font-size: 21px;
    border: 0;
    cursor: pointer;
    display: inline-block;
    padding: 4px 9px;
    vertical-align: top;
    line-height: 100%;   
}
input[type="text"],
select{
    padding:5px;
}

            </form>
        </div>
    </div>
</div>

    $scope.albums = [

    ];
    $scope.addOrSaveAlbum = function() {

        }else {
            $scope.albums.push({ title: $scope.editing.title, artist: $scope.editing.artist });
        }            
            $scope.editing = {};
        };        
    $scope.onChange = function() {
