您可能会使用jQueryUI的自动完成破解行为类似的东西，例如:

You could probably use jQueryUI's autocomplete to hack something up which behaves similarly, for example:

var fruits = ["apples", "oranges"];
$("input").autocomplete({
    source: fruits,
    minLength: 0
}).autocomplete("search", "");


Select preset from list or type something: <input type="text"/>

在这里玩.
