我正在尝试使用库Select2来实现。假设我有如下数据列表：
[当我输入“水果”时，是否只能显示Apple，香蕉和橙子，而当我输入“体育”时，可以显示篮球和足球。含义是否存在“相关搜索/标记”类型的功能？
谢谢！
您可以做这样的事情：
搜索文档：https://select2.org/searching
function matchCustom(params, data) {
const term = $.trim(params.term);
if (term === "fruit" || term === "sports") {
if (data.type === term) {
return data;
}
return null;
}
return data;
}
const data = [
{
id: 0,
type: "fruit",
text: "apple"
},
{
id: 1,
type: "fruit",
text: "orange"
},
{
id: 2,
type: "sports",
text: "football"
},
{
id: 3,
type: "sports",
text: "basketball"
}
];
$(document).ready(() => {
$(".js-example-basic-single").select2({ data, matcher: matchCustom });
});.js-example-basic-single {
width: 100%;
