我已经成功设置了一个从我的“multiselect_json.php”文件中动态填充的多选框。（这里的多选插件：https ://github.com/nicholasryan/jquery_jeditable/commit/1055cf6d51100d241b1e089c8cabcbad26207320 ）
我的问题是我只能返回 1 个标记为“已选择”的值对
例子：
我的下拉选项如下： 1-product1 2-product2 3-product3
数组（'选择'）= 1；有效并正确突出显示此选项
但是当我指定 2 个选定选项时不起作用
数组（'选择'）= 1；
数组（'选择'）= 2；
在这种情况下，使用最后一个“选定”值 (2)，而忽略前一个“选定”值 (1)。
这意味着如果在特定的多选列表中有许多预选项目，那么用户很难记住之前选择的内容，并且必须返回并重新选择之前手动选择的内容。
有谁知道如何使用 jeditable 插件为我的多选框传递多个“选定”值对？
