    javascript - Select2 TypeError: b is undefined - Stack Overflow

    programmeradmin1浏览0评论

    I'm using select2 to show ajax results in a dropdown but when I append data to select2 its showing error 

    TypeError: b is undefined

    JS Code

            var baseurl = $("#baseurl").val();
        $(".myselect").select2({
            placeholder: "Select a inspector",
            allowClear: true,
            ajax: {
                url: baseurl + '/admin/getdata',
                dataType: 'json',
                type: "GET",
                quietMillis: 50,
                data: function (term) {
                    return {
                        term: term.term
                    };
                },
                results: function (data) {
                    var myResults = [];
                    $.each(data, function (index, item) {
                        myResults.push({
                            'id': item.id,
                            'text': item.firstname
                        });
                    });
                    return {
                        results: myResults
                    };
                }
            }
        });

    term.term contains the value of input text in dropdown search box.

    Reset to default 14

    In your ajax configuration you use results you should use processResults

    Try this

    var baseurl = $("#baseurl").val();
    $(".myselect").select2({
        placeholder: "Select a inspector",
        allowClear: true,
        ajax: {
            url: baseurl + '/admin/getdata',
            dataType: 'json',
            type: "GET",
            quietMillis: 50,
            data: function (term) {
                return {
                    term: term.term
                };
            },
            processResults: function (data) {
                var myResults = [];
                $.each(data, function (index, item) {
                    myResults.push({
                        'id': item.id,
                        'text': item.firstname
                    });
                });
                return {
                    results: myResults
                };
            }
        }
    });

    Aamir@, sometimes errors are misleading. If you see from your code, it doesn't have a reference to b at all. I believe that must be an error that is being thrown from a method outside of your code, due to an error in your code.

    You might have to set a break point by clicking on the line number on browser console and then check the call stack to find the error in the code.
