通过在 Select2 插件中使用匹配器功能，不会出现未找到结果的消息

Question

In normal the the no results found message shows when unrecognised name enters, but by adding the below code to filter results to show only the first letter matches there is no message shown.

 function matchStart(params, data) {
    params.term = params.term || '';
    if (data.text.toUpperCase().indexOf(params.term.toUpperCase()) == 0) {
        return data;
    }
    return false;
}

$("select").select2({
    placeholder: "Input country name or select region",

    noResults: function () {
        return"No results found"
    },
    matcher: function (params, data) {
        return matchStart(params, data);
    },
});

Answer 1

Know this is an old one but I managed to find an answer here: selec2 search - Return no results found message if a specific criteria didnt match

So credit to user ikkuh for the answer. My issue was with returning false in the matcher function, try returning null instead - worked for me!

Answer 2

You need replace "return false;" to "return null;" in function matchStart
