以下代码工作正常，但一次只有一个值，我希望选择多个值，用逗号分隔。例如，我从下拉列表中选择了阿拉巴马州，然后当我给出逗号示例：阿拉巴马州，并输入一个新字母，例如 C [示例：阿拉巴马州，C]，下一组项目必须显示在下拉列表中所以最后我会在 TextBox 示例中具有以下值：Alabama,California

Dojo Filtering 选择小部件不允许选择多个项目。考虑使用 Dojo MultiSelect 小部件作为替代方法。

看：

你应该看看 CheckedMultiSelect：

https://dojotoolkit.org/reference-guide/1.9/dojox/form/CheckedMultiSelect.html

它同时具有下拉菜单和多选功能。要更改显示的标签，有趣的代码在函数中_updateSelection：

        this.dropDownButton.set("label", this.multiple ?
            lang.replace(this._nlsResources.multiSelectLabelText, {num: i}) :
            label);

它显示标签n item(s) selected。如果您想用逗号分隔项目，这是插入代码的好地方。
