Question

我正在使用yii2-advanced-app。我遇到问题，如下面的快照所示 -

如果我选择任何主要类别，则所有子类别都在变化，而不仅仅是相应的子类别。

我的观看代码如下 -

<div class="row">
        <div class="panel panel-default">
            <div class="panel-heading"><h4><i class="glyphicon glyphicon-envelope"></i> Add More Categories</h4></div>
                <div class="panel-body">
                     <?php DynamicFormWidget::begin([
                        'widgetContainer' => 'dynamicform_wrapper', // required: only alphanumeric characters plus "_" [A-Za-z0-9_]
                        'widgetBody' => '.container-items', // required: css class selector
                        'widgetItem' => '.item', // required: css class
                        'limit' => 4, // the maximum times, an element can be cloned (default 999)
                        'min' => 1, // 0 or 1 (default 1)
                        'insertButton' => '.add-item', // css class
                        'deleteButton' => '.remove-item', // css class

                                                'prompt' => 'Select Sub Category'
                                            ]);
                                        ?>
                                        </div>
                                    </div><!-- .row -->                                    
                                </div>
                            </div>
                        <?php endforeach; ?>
                    </div>
                    <?php DynamicFormWidget::end(); ?>
                </div>
            </div>
        </div>
    </div>

此外，点击＆＃39;添加＆＃39;按钮，它会在Uncaught TypeError: Cannot read property 'widgetItem' of undefined中显示错误yii2-dynamic-form.js。

我哪里错了？请告诉我。

Answer 1

将Java脚本用于操作事件...使用bind来避免多次触发

Answer 2

您的表格和型号都是一些或不是？我的意思是说你的表格属于不同的模型而且你传递的是不同的模型。

Yii2-动态形式
