Select2和initSelection回调 [英] Select2 and initSelection callback

问题描述

在页面加载时，我尝试使用initSelection选择ID 60 (输入字段的指定值).我似乎无法使其正常工作.

On page load, I'm trying to use initSelection to select ID 60 (specified value of the input field). I can't seem to get it to work properly.

PHP脚本可以很好地工作并返回正确的值，但是如何获取JS才能正确执行回调?

The PHP scripts work great and return the correct values, but how do I get the JS to do the callback correctly?

JavaScript:

$(document).ready(function() {
    $('#editAlbumArtistId').select2({
            placeholder: 'Search names',
            ajax: {
                url: "/jQueryScripts/jQuerySelectListArtists.php",
                dataType: 'json',
                quietMillis: 100,
                data: function (term, page) {
                    return {
                        term: term, //search term
                        page_limit: 10 // page size
                    };
                },
                results: function (data, page) {
                    return {results: data.results};
                }

            },
            initSelection: function(element, callback) {

            var id = $(element).val();
            if(id !== "") {
                $.ajax("/jQueryScripts/jQuerySelectListArtists.php", {
                    data: {id: id},
                    dataType: "json"
                }).done(function(data) {
                    callback(data);
                });
            }
        }
    });
});

HTML:

<p>
    <input type='hidden' value="60" data-init-text='Search names' name='editAlbumArtistId' id='editAlbumArtistId' style="width:180px;"/>
</p>

每次刷新页面时，都会看到PHP脚本得到执行，并且返回正确的ID和文本.但是，该字段没有更新，我已经认真尝试了我能想到的一切.

Every time I refresh the page, I see that the PHP script gets executed and that it returns the proper ID and text. However, the field isn't updated and I've seriously tried everything I can think of.

我正在使用Select2 3.4.3.

推荐答案

终于解决了！我发现select2不需要数组，因为它是单个值，所以我选择了data.results数组的第一个元素.

Finally solved it! I figured select2 didn't want an array since it's a single value, so I selected the first element of the data.results array.

callback(data.results[0]);

如果您设置了multiple:true，则只需接受整个结果数组；

And if you have set multiple:true, just accept the entire results array;

callback(data.results);
