为此目的有一个内置标签。

用户在文本框中输入一个字符，以输入的字符开头的字符串应该以列表的形式显示。从列表中选择的项目应填充在文本框中。

PS：示例和演示可用显示包含输入字符的字符串。但我只想显示以输入字符开头的那些字符串。

A way to do that is shown in the wiki page of the pluguin where it says: Autocompleter that handle a JSON Result. Yo just set that code in your jsp, and then you implement something like this in your action:

    private static String[] staticLanguages = { ...a list... };                                                                                      
    private String term;
    private String[] languages  = Autocompleter.staticLanguages;
    public String execute() throws Exception {
            if (term != null && term.length() > 1)
            {
                    ArrayList<String> tmp = new ArrayList<String>();
                    for (int i = 0; i < staticLanguages.length; i++)
                    {
                            if (StringUtils.contains(staticLanguages[i].toLowerCase(), term.toLowerCase()))
                            {
                                    tmp.add(staticLanguages[i]);
                            }
                    }
                    languages = tmp.toArray(new String[tmp.size()]);
            }
            return SUCCESS;
    }

Just change StringUtils.contains line and check instead if the begining is the same.

The jsp tag would be:

<sj:autocompleter 
    name="term"
    id="languages" 
    href="%{remoteurl}" 
    delay="50" 
    loadMinimumCount="2"
/>

I think this should work. Just take a look at the example code in the wiki and try it out.

我使用 Struts2 和 Jquery 制作了自己的自动完成实用程序，它们从 oracle 读取数据并显示建议列表，您可以根据您的要求进行相应更改。请从这里下载代码http://javaant.com/dynamic-autocomplete-using-jquery-struts2-and-oracle/#.V0RxL5N96Hs
