如何在 HTML/Javascript 中创建可编辑的组合框? [英] How can I create an editable combo box in HTML/Javascript?
问题描述
我需要让用户从下拉列表中选择一个项目,但也允许他们输入任何文本,即使它与列表中的项目不匹配.如何在带有 HTML 和 Javascript 的网页上实现此目的?
I need to let users select an item from a dropdown list, but also allow them to instead enter any text, even if it doesn't match an item in the list. How can I achieve this on a web page with HTML and Javascript?
select
字段不允许用户输入文本,input
文本字段不显示首选选项.
The select
field doesn't let users enter text, and the input
text field doesn't show the preferred alternatives.
如果用户打开下拉菜单,所有项目都必须显示,因此它不能是仅显示匹配项目的简单自动完成.
All items must show if the user opens the dropdown, so it can't be a simple auto-complete that only shows matching items.
推荐答案
或另一种工作方式略有不同的:链接已删除(站点不再存在)
Or another one which works slightly differently: link removed (site no longer exists)
