Question

以下代码工作正常，但一次只有一个值，我希望选择多个值以逗号分隔。例如我从下拉列表中选择了Alabama，然后当我给逗号做例子：Alabama，并输入一个新的字母，比如C [例如：Alabama，C]，下一组项目必须显示在下拉列表中最后，我将在TextBox示例中使用以下值：加利福尼亚州阿拉巴马州

Answer 1

Dojo过滤选择窗口小部件不允许选择多个项目。考虑使用Dojo MultiSelect小部件作为替代方案。

请参阅：

Answer 2

你应该看看CheckedMultiSelect：

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

它包含下拉菜单和多项目。要更改显示的标签，有趣的代码在函数_updateSelection中：

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

显示标签n item(s) selected。如果你想用逗号分隔项目，那么它就是插入代码的好地方。
