javascript - jQuery Select2 : [object Window] in tags value

Question

我使用 Select2 插件来显示标签。

JS:

$(document).ready(function () {
    $("#tags").select2({
        tags: true,
        minimumInputLength: 3,
        tokenSeparators: [','],
        createSearchChoice: function (term) {
            return {
                id: $.trim(term),
                text: $.trim(term)
            };
        },
        ajax: {
            url: "./controller/citynames.php",
            dataType: "json",
            data: function (term, page) {
                return {
                    q: term
                };
            },
            results: function (data, page) {
                return {
                    results: data
                };
            }
        },

        // Take default tags from the input value
        initSelection: function (element, callback) {
            var data = [];

            function splitVal(string, separator) {
                var val, i, l;
                if (string === null || string.length < 1) return [];
                val = string.split(separator);
                for (i = 0, l = val.length; i < l; i = i + 1) val[i] = $.trim(val[i]);
                return val;
            }

            $(splitVal(element.val(), ",")).each(function () {
                data.push({
                    text: this
                });
            });

            callback(data);
        },

        // Some nice improvements:

        // max tags is 3
        maximumSelectionSize: 5,

        // override message for max tags
        formatSelectionTooBig: function (limit) {
            return "Max tags is only " + limit;
        }
    });
});

HTML:

<input type="hidden" id="tags" value="test1,test2," style="width: 400px;">

现在我有两个问题:

1- 我的 html 操作我有两个 value="test1,test2," 但在 html 输出中我只看到一个值:test1 !!

2- 我检查元素，我看到 3 个值:test1,test2,[object Window]

我该如何解决这个问题？!

Answer 1

你需要在你的initSelection中添加id

data.push({
    id:this,
    text: this
});
