大概的意思是知道,就是关于短链转换的,但细节还不是太清楚,js 达人帮忙注释下吧,非常感谢!define("task/shortURL",
function(a, b, c) {
    var d = a("task/TaskManager"),
    e = a("task/Task");
    d.add(new e("shortURL",
    function() {
        var b = a("external/jquery"),
        c = a("utils/DataSource");
        b(document.body).delegate(".short-url:not(.processed)", "mouseenter",
        function(a) {
            var d = b(a.target),
            e = d.addClass("processed").text();
            if (e.indexOf("http://163.fm") === 0) {
                var f = e.substr(14);
                c.get("longUrl", {
                    q: f
                },
                function(a) {
                    d.attr("title", a)
                },
