JSP中基于上下文的搜索 [英] Context based search in JSP

问题描述

我对
< Select>< option />< / select>
标签存在一个奇怪的问题。我不写任何代码来启用上下文搜索（例如，如果我键入A，它将列出与A，AA，A，AB，AB，AC，AC等所有可能的组合（不以相同的顺序）） 。类似地，如果我输入Ab，它应该列出所有以Ab开头的组合，但问题是你必须在这里快一点，否则，如果我按A并等待一段时间，然后按B，那么我将获得以B开头的所有内容而不是AB，这是什么意思。是否有这样的替代，以便我输入的任何内容都将得到apt搜索结果

解决方案

p>您所描述的是由浏览器（和/或用户可能已安装的插件）提供的行为，因此如果对于不同的客户端可能会有所不同。

为了获得一致的可自定义您需要将行为替换为标准< select>与基于JS的组件。查看 ExtJS ComboBox实施例如;还有很多其他可用的。

I have a strange issue with the
<Select><option/></select> tag.I don't write any code to enable context search(ie. if I type A it will list all possible combinations with A like AA,Aa,Ab,AB,Ac,AC and so on(not in the same order)).Similarly if I type Ab it should list all combinations starting with Ab which it does but the problem is you have to be little quick here otherwise if I press A and wait some time and then press B then I wil get all contents starting with B and not with AB which is what was intented.Is there an alternate to this so that whatever I type will get the apt search results

解决方案

What you're describing is a behavior provided by the browser (and/or plugin(s) user may have installed), therefore if may differ for different clients.
In order to have a consistent customizable behavior you'll need to replace standard <select> with JS-based component. Look at ExtJS ComboBox implementation for example; there are many others available as well.
