javascript - 如何自动链接一系列 ajax 请求？

Question

看看我的函数的下半部分:我想重复 info(url_part1 + next + url_part2, function(next) { 几次。有没有比下面介绍的方法更聪明的方法(也许是某种循环)？我想了一整天，但想不出任何办法。

 function info(link, callback) {
        $.getJSON(link, function(json) {
            $.each(json.data.children, function(i, things) {
                $("#threadlist").append('<img src="' + things.data.url + '">');
            });
            callback(json.data.after);
        });
    }
    var url_first = "http://www.reddit.com/r/aww/.json?jsonp=?";
    var url_part1 = "http://www.reddit.com/r/aww/.json?after=";
    var url_part2 = "&jsonp=?";

    info(url_first, function(next) {
        info(url_part1 + next + url_part2, function(next) {
            info(url_part1 + next + url_part2, function(next) {
                info(url_part1 + next + url_part2, function(next) {
                    info(url_part1 + next + url_part2, function(next) {

                    });
                });
            });
        });
    });
