只是想知道是否可以调整我的代码以在加载时在页面上显示第一个目录的图像,以便在用户单击菜单选项之前显示它们,因为页面看起来有点熊,直到菜单选项为止选中,这是我的代码,谢谢。

  $(document).ready(function() {
    $("a").click(function() {
      var dir_path = $(this).data("albumid");
      //var txt=$(this).text();

      LoadGallery(dir_path);
      return false;

LoadGallery($('a[data-albumid]:first').data('albumid'));功能中添加$(document).ready(),如下所示。 $('a[data-albumid]:first')会选择具有a属性的第一个data-albumid。希望这会对你有所帮助。

$(document).ready(function () {
    LoadGallery($('a[data-albumid]:first').data('albumid'));

    $("a").click(function () {
        var dir_path = $(this).data("albumid");
        //var txt=$(this).text();
        //$(this).text(txt);
        LoadGallery(dir_path);
        return false;
    });
});
