Changing search behavior in jquery plugin Chosen
提问by David W.
I'm using the Chosen plugin for jQuery and would like the search behavior to change a bit (single select). Searching only results in hits where the beginning of a word in the seach string matches. I would like to extend this to also hit words after slash and brackets.
我正在使用 jQuery 的 Chosen 插件，并希望搜索行为有所改变（单选）。搜索结果只匹配搜索字符串中单词开头的匹配项。我想将其扩展到斜线和括号后的单词。
For example: search string: "second" does not match items "first/second" or "first (second)".
例如：搜索字符串：“ second”不匹配项目“ first/second”或“ first (second)”。
I doubt this is changeble by simply adding options to constructor, but I am willing to change/hardcode source script.
我怀疑这是否可以通过简单地向构造函数添加选项来改变，但我愿意更改/硬编码源脚本。

As mentionned in some more recent answers, the plugin now implemements an option to change the search behavior:
正如在最近的一些答案中提到的，该插件现在实现了一个更改搜索行为的选项：
search_contains: true
The plugin does not provide an option to change the search method behavior.
该插件不提供更改搜索方法行为的选项。
If you're willing to change the plugin source itself, here's a way to do it.
如果您愿意更改插件源本身，这是一种方法。
The method that makes the search in the plugin is Chosen.prototype.winnow_results. It uses a regular expression that matches text that "starts with" the search term:
在插件中进行搜索的方法是Chosen.prototype.winnow_results. 它使用一个正则表达式来匹配“以”搜索词开头的文本：
// "^": means "starts with"
// "searchText" is the text in the search input (it is just cleaned up don't be scared)
regex = new RegExp('^' + searchText.replace(/[-[\]{}()*+?.,\^$|#\s]/g, "\$&"), 'i');
Change it to:
将其更改为：
regex = new RegExp(searchText.replace(/[-[\]{}()*+?.,\^$|#\s]/g, "\$&"), 'i');

The search behavior can be set with the option search_contains
可以使用选项设置搜索行为 search_contains
This is by default false
这是默认的 false
Set it to true, and chosen will also find matches inside instead of only the beginning:
将其设置为true, 而 selected 也会在内部找到匹配项，而不仅仅是开头：
$('#my_dropdown').chosen({ search_contains: true });

As in Chosen 1.0, just add option {search_contains: true}
在 Chosen 1.0 中，只需添加选项 {search_contains: true}
$('.selector').chosen({search_contains: true});
Have fun.
玩得开心。

有选项search_contains可用于搜索选项中的子字符串，可用作：
$(".chosen-select").chosen({
search_contains: true
});

in chosen 1.0 i did on line 301&302
在选择的 1.0 中，我在第 301 和 302 行做了
escapedSearchText = searchText.replace(/[-[\]{}()*+?.,\^$|#\s]/g, "\$&");
regexAnchor = "";
