HTML select tag autocomplete
提问by kfirba
I got some select tag as follows:
我得到了一些选择标签，如下所示：
<select id="fruits">
<option value="1">Apple</option>
<option value="2">Banana</option>
<option value="3">Orange</option>
<option value="4">Grapes</option>
<option value="5">Ginger</option>
</select>
What I want to do is, whenever the user focus on the select, and he's clicking on the key "G" in his keyboard, the option "Grapes" will be automatically selected, and when he presses "G" once again, "Ginger" will be selected and so on.
我想要做的是，每当用户关注select，并且他G在键盘上单击“ ”键时，Grapes将自动选择选项“ ”，当他G再次按下“ ”时，Ginger将选择“ ”并很快。
I have no clue how to do it.
我不知道该怎么做。

Well, If you want to add Auto Complete functionality to your html select element then there is nothing better than selectize.js
好吧，如果你想为你的 html select 元素添加自动完成功能，那么没有比 selectize.js 更好的了
All you need to do is either include its css and js file in your project or you can use cdns.
您需要做的就是在您的项目中包含其 css 和 js 文件，或者您可以使用 cdns。
Go to Selectize website here
去这里选择网站

I think this is the default action of drop down(select control). You have to do zero effort to achieve it.
我认为这是下拉（选择控件）的默认操作。你必须做零努力来实现它。

This need no effort to be made. Try it out yourself in any browser. Browser do it for you by default. Try on chrome or any current browser
这不需要努力。在任何浏览器中自己尝试一下。浏览器默认为你做。尝试使用 chrome 或任何当前浏览器
Eg: Facebook page signup form:
例如：Facebook 页面注册表单：
just select the month and press J
只需选择月份并按 J
first it will show january
首先它会显示一月
on second press of Jit will show june.. and so on
第二次按下J它会显示六月.. 依此类推
