我正在使用Select2来设置我的选择框并添加功能,我想知道如何使搜索规则更加宽松。目前,如果我在下拉列表中有“新墨西哥”,我可以搜索“墨西哥”或“新墨西哥”以匹配选择选项,但如果我输入“mexico new”,我会“找不到结果”。有没有办法扩展搜索功能以匹配搜索词而不管它们的顺序?
$(document).ready(function() {
$(".states").select2();
});

好吧,显然你可以设置custom matchers来完成这个任务。我找到了this one,它似乎正在按预期工作:
$(function () {
$('.states').select2({
matcher: function (params, data) {
if ($.trim(params.term) === '') {
return data;
}
keywords=(params.term).split(" ");
for (var i = 0; i < keywords.length; i++) {
if (((data.text).toUpperCase()).indexOf((keywords[i]).toUpperCase()) == -1)
return null;
}
return data;
}
});
});
