Question

我尝试按照http://select2.github.io/select2/的示例进行操作，以使我的基本select2 ajax远程数据正常运行。但是，它返回错误为

未捕获的错误：无select2 / compat / initSelection

我四处搜寻，发现了类似的问题select2 - initselection error，但模糊不清可以帮助解决当前的问题。

                return { results: data.items };
            },
            cache: true
            // Additional AJAX parameters go here; see the end of this chapter for the full code of this example

          initSelection: function(element, callback) {
                // the input tag has a value attribute preloaded that points to a preselected repository's id
                // this function resolves that id attribute to an object that select2 can render
                // using its formatResult renderer - that way the repository name is shown preselected
                var id = $(element).val();
                if (id !== "") {
                    $.ajax("https://api.github.com/repositories/" + id, {
                        dataType: "json"
                    }).done(function(data) { callback(data); });
                }
            },

            escapeMarkup: function (m) { return m; } // we do not want to escape markup since we are displaying html in results
        });
    </script>
</body>

上面的代码有什么问题？我想知道它的哪一点对我来说是正确的，并且可以正常工作？谢谢。
