Answer 1

代码:

    var dir = "Src/themes/base/images/";
var fileextension = ".png";
$.ajax({
    //This will retrieve the contents of the folder if the folder is configured as 'browsable'
    url: dir,
    success: function (data) {
        //List all .png file names in the page
        $(data).find("a:contains(" + fileextension + ")").each(function () {
            var filename = this.href.replace(window.location.host, "").replace("http://", "");
            $("body").append("<img src='" + dir + filename + "'>");
        });
    }
});

这将加载文件夹中存在的所有图像 .png，请注意此代码使用 jquery。
