Here, when we select city, then a special list box like control opens, which shows all the cities alphabetically.

Tell me some sample or other about it.

推荐答案

when we select city then a special list box like control open ...
which show all the cities alphabetically...

他们只是在城市选择活动中显示一个div.在div中，城市已经按字母顺序填充.

您只需要在城市文本框中的onkeydown事件上显示/隐藏div.尝试！

They are just showing up a div on city select event. In the div, the cities are already populated in alphabetical order.

You just need to show/hide a div on the onkeydown event on city textbox. Try!

在ASP.NET中轻松放置列表框，请参阅此处 [ ^ ].

但是，该页面中的内容是执行相同操作的脚本.
Tha是的，文本框是按常规填充的，但是onmousehover调用了(我认为)php脚本来显示选项，而不是标准列表框.

此 [

Poplating a listbox in ASP.NET is easy, see here[^].

What you have in that page, though, is a script to do the same.
Tha is, the text box is populated as per normal, but onmousehover calls a (I think) php script to show the options rather than a standard listbox.

This[^] may help you too.

此外，您还可以将jQuery与许多UI插件一起使用或Ajax Control Toolkit，其中有许多扩展程序可改善用户界面.

Also you can use jQuery with many UI plugins or Ajax Control Toolkit where there are many extenders to improove User Interface.
