javascript - ckeditor 插件对话框选择从所选的获取描述

Question

我正在为 CKEDITOR 开发一个占位符插件，它基本上已经完成了。我遇到的问题是，我试图从对话框中的 select 获取值和 description，但我只获取了值。包含描述和值的数组如下所示

-->项目:[['description1', 'value1'], ['description2', 'value2']] <--

在 return -> contents -> elements with ID dropdown 我有 setup 和 提交功能。在这些函数中，我需要像从选择选项中获取名称一样获取描述。

真的需要这方面的帮助，在此先感谢

示例 -->

<select>
    <option value="value1">description1</option>
    <option value="value2">description2</option>
</select>

                var data = { tag: 'link', content: null, title: null, text: null };

                this.commitContent(data);

                CKEDITOR.plugins.phlink.createPlaceholder(editor, this._element, data);

                delete this._element;
            }
        };
    }

    CKEDITOR.dialog.add('createplaceholder', function (editor) {
        return placeholderDialog(editor);
    });
    CKEDITOR.dialog.add('editplaceholder', function (editor) {
        return placeholderDialog(editor, 1);
    });
})();

使用以下命令获取选项的文本:

var input = this.getInputElement().$;
console.log( input.options[ input.selectedIndex ].text );
>> "description1"
