我如何通过自定义主轴编辑器按钮调用模式

Question

我在羽毛笔编辑器中有一个自定义按钮（embed），它使用提示来调用Windows弹出窗口

现在，我想单击embed按钮将窗口弹出窗口更改为模态。

老实说，我不知道该怎么做，因为这是我第一次使用鹅毛笔。

我正在使用鹅毛笔扩展名文件创建自定义按钮（embed）

我很困惑，是要创建模态以及单击主轴定制按钮时如何调用模态。

这就是我从视野中称呼鹅毛笔的方式

<div class="form-group col-xs-12">
                                <label class="control-label">
                                    Description
                                </label>

                                <div id="createSchool_Description_div" style="height:300px;"></div>


</div>
 <script>
        $(document).ready(function () {



<text>  
      prepareQuill('#createSchool_Description_div');  
 </text>

}

我的羽毛笔扩展名文件

我认为您无需为此编写自定义按钮，因为鹅毛笔已经具有视频嵌入按钮。

在创建下面的羽毛笔示例时，只需在工具栏选项中添加“视频”：

    ['bold', 'italic', 'underline', 'strike', '**video**']]
